  • How Does Metal Casting Work?
    Nov 04, 2022

    The metal casting process can create anything from tiny fasteners to large industrial components, all through a five-step procedure. It happens by creating a pattern and making a mold, melting and transferring the metal and finishing, cleaning, polish and inspecting the casting. While metal casting is a straightforward practice, it requires specialized skills and techniques to perfect.

    At Hengchang Foundry, we have the mastery and technology to form objects of various sizes for different industries like heavy equipment and transportation. No matter the complexity of the parts you require, our professional team can produce tailored castings to deliver unique parts for your application.

    What is the metal casting process? Continue reading to learn what to know about metal casting and how our metal casting services work.

    1. MAKING THE PATTERN

    When talking about a pattern, we aren’t referencing one you trace on a piece of paper. Instead, metal casting foundries refer to patterns as a replica of the object they’re casting. This pattern helps form the mold cavity, which can be made of wood, plastic, aluminum and many other suitable materials. Making a pattern is a crucial first step because the accuracy of the mold determines the accuracy of the final product.

    The four steps in producing a precise pattern include:

    1. Shaping the mold cavity
    2. Adapting the properties of the metal cast
    3. Referencing accurate dimensions
    4. Creating a way for the liquid metal to enter the mold

    Depending on the type of material being poured into each mold, the final, solid product will distort to a certain degree. For example, it may shrink compared to the original size of the mold. This is why each pattern has allowances for slight alterations. Additionally, patterns require a draft, or a vertical tapered wall, where professionals can extract the pattern without tampering with the molded product.

    2. CREATING THE MOLD

    It’s now time to create the mold, which is a hollow shape that will form the metal later on in the process. While some molds are expendable, others are nonexpendable.

    An expendable mold means you can’t use it again. In that case, materials like sand, plaster foam or plastic make up the mold, and they’re destroyed during the casting process. Alternatively, you can use nonexpendable molds indefinitely, as they’re often made of aluminium.

    Both expendable and nonexpendable molds can support different pattern complexities and materials.

    3. MELTING AND TRANSFERING THE METAL

    While we use a multitude of materials for metal casting, they all fall under one of two categories — ferrous and non-ferrous metals. The metals used in metal casting can include iron, zinc, aluminum, tin, copper, lead alloys and others. While a ferrous metal contains malleable iron or steel, a non-ferrous metal contains nonmalleable metal, such as copper, nickel or aluminum.

    After selecting the appropriate metal type, we load it into the furnace where temperatures rise until it reaches the material’s melting point. At Warner Brothers Foundry Company, we use gas furnaces during the metal casting process, though there are two other common types of furnaces for metal casting — electric arc and induction.

    Using electric furnaces is our preferred method for metal casting because it burns cleanly and efficiently. Electric furnaces also allow us to heat the metal to the necessary temperatures without using high amounts of electricity. Electric furnaces are more efficient for our process, which keeps costs lower on our end and allows us to offer lower prices on your end.

    Once the material melts down, it’s transferred to a large ladle before it reaches the mold. Through gates and risers, or openings in the mold, workers or machines pour the liquid material into the mold. Once it takes shape, solidifies and cools, we eject the casting from the mold, removing excess metal from the gate and rider system before moving to the next step in the process.

    Understanding how long metal casting takes depends on the material — some may cool within minutes, and others take several days.

    4. FINISHING AND CLEANING EACH PART

    This stage involves making the final touches and cleaning each individual part. At Hengchang Foundry Company, we go in and remove excess metal parts and begin the cleaning process, using different tools to clear away particles and dirt. The final product is the same proportion and shape as the original pattern used during step one.

    Additionally, some products may require a heat treatment, such as rail clamp, hydraulic cylinder, buffer. This process alters the properties of the material through a heating and cooling technique where the metal becomes more resilient. These treatments are ideal for applications that may endure extreme weight, wet environments or freezing temperatures.

    5. INSPECTING THE CASTING

    The metal casting process ends with an inspection to ensure everything is complete and up to our standards. During the final stage, we check the part’s physical structure and integrity to ensure it’ll hold up and perform the expected job.

    There are destructive and nondestructive testing methods, which are put in place depending on the casting’s specifications. In particular, visual inspections include looking for cracks, accuracy and surface finishes, and more in-depth testing checks tensile strength, hardness and ductility, among other components.

    No matter the industry, we inspect everything from trailer hitches and industrial equipment to small automotive parts. In the end, you’ll have a durable component that’s suited to your unique needs and operations.

  • What is the difference between ductile iron and cast iron?
    Oct 12, 2022

    Ductile iron is an alloy of cast iron or grey iron in which the carbon forms into nodules as opposed to plates as it is in grey iron. This makes the metal more ductile than cast iron hence the name.

    Ductile iron has greater strength and ductility than gray iron. Those properties allow it to be used effectively in a wide variety of industrial applications, including pipe, automotive components, wheels, gear boxes, pump housings, machine frames for the wind-power industry, and many more.

  • Preliminary Raw Casting Inspect
    Oct 21, 2022

    After produce the items, the preliminary casting inspection will use the visual. This inspection way involves using the human eye to detect surface defects, tears, misruns, cracks, cold shuts, gas evolution, molding flaws, metal penetration, slag adhesions and sand inclusions. This inspection is essential to ensure the casting adheres to visual acceptance standards. Inspection results should be documented and recorded, and every surface irregularity should be classified. Any castings with visually detected defects should be picked out and not moved to next steps or delivered to customers. The inspection way always use in the casting parts with different material, such as QT450-12, QT500-7,QT600-3 etc

  • Sand Casting Process
    Oct 28, 2022

    The Sand Casting Process

    Even a child playing at the beach or in a sandbox can immediately grasp how sand casting works. When you see a child mixing water into sand to make it easier to shape it into a sand castle, that child is demonstrating how combining some sand and water works so beautifully for creating a shape. 

    At its simplest, the sand casting process for a casting foundry  is nothing more than making a cavity in the sand in the desired shape, pouring molten metal into the cavity and letting it cool. Humankind has been doing this for thousands of years. Sand is heat resistant and readily available almost anywhere on earth. 

    If you’ve ever noticed the way footprints made in wet sand hold their shape, you can easily imagine what likely inspired the first ancient metal workers to use wet sand to shape their cast metals. Everything after that has just refined and perfected the basic process.

    What Is Green Sand Casting?

    The term green sand has nothing to do with the color of the sand casting material. It means there’s some moisture in the sand; when the sand is said to be green, it means the mold has not been baked or dried. This kind of molding sand is a very economical and versatile material. When desired, the foundry can add select additives can make the green sand more ideal for a specific purpose. Green sand is used in the most common sand casting processes.

    How Do You Make Sand Casting Molds?

    Sand casting equipment within a foundry can be very basic or quite advanced, depending on the items being made. Typically, the sand is placed in a mold box, which is known as a flask. The pattern, or model, is placed in the prepared sand inside the flask to make a mold. The pattern is removed, leaving behind a perfect shape in the sand. The mold is filled with molten metal, which is allowed to cool. When the metal is sufficiently cooled, the sand mold can be broken away.

    More complicated items can be cast by combining an upper and a lower section. The upper mold is known as the cope, while the bottom half is known as the drag. Once the cope and drag are ready, they can be fastened together so that molten metal can be poured into the resulting cavity. Even further detailing is possible with the addition of a core. A core is something placed inside the mold to form a negative space that no molten metal will fill. An example would be the middle of an engine block or any other cast item that requires a hollow space.

    Castings made with cope and drag must provide a way to introduce the molten metal into the mold. It can be a simple vertical passage, known as a sprue. The sprue and its channel will fill with molten metal that will solidify and will need to be machined off to get the item to its final design.

    How Does The Sand Casting Process Work?

    In the modern foundry or casting industry, the knowledge of how each alloy will react with each potential form of mold and each potential additive allows the worker to make choices to give the finished item the desired characteristics. Metal casting is both an art and a science.

    As the molten metal cools and solidifies, it will give off gasses. The molds are designed to take that into consideration and when necessary, will be constructed to allow the gasses to escape throughout the sand casting process.

    What Is Sand Casting Used For?

    Chances are good that you’re less than 10 feet from at least one cast item right now that has been through the sand casting process. There’s hardly an industry that doesn’t have some kind of need for cast materials. Some cast items are large and can weigh hundreds of pounds, while other cast items are tiny and intricate.

    What Are Some Common Metals Used in Sand Casting?

    Almost any kind of metal can be shaped using the right sand casting equipment. Grey iron and ductile iron very well.

    What Additives Are Common In Sand Casting?

    Modern manufacturers will usually add some water and other additives to the sand casting process to make it work better for various purposes. Different alloys and different items call for additives, including these common materials:

      • Clay: It could be bentonite clay (most likely calcium bentonite) or another kind of clay. For special delicate and high-detail items, such as jewelry, Delft clay, which is imported from the Netherlands, can be used.
      • Coal Dust: Also known as Sea Coal, this is added to produce a more even surface, to make it easier to get the cast item out of the mold. It also produces casts with fewer defects.
      • Corn Flour: Believe it or not, a little bit of corn flour added to the wet sand gives the sand greater strength and plasticity.
      • Dextrin: Dextrin, derived from corn starch, is used as a binder. It improves the dry surface strength of the sand.
      • Pitch: Made from soft coal, a little pitch added to the sand improves the surface finish.
      • Wood Flour: This material is combustible, which like other combustible additives helps create a space for the grains of sand to expand without changing the shape of the mold.
      • Silica Flour: This material is just finely ground sand that’s mixed into casting materials for a more durable mold. 

    What’s The Future In Sand Casting?

    Relatively new technology in today’s casting foundry is 3D printed patterns and molds.
    The latest 3D printing equipment is capable of manufacturing a sand mold and core in just a few hours. This can save considerable time and money in some cases. 

    Once the pattern is produced, sand casting proceeds as usual, but the ability to use a 3D printer to produce the pattern, molds and cores greatly speed up the process, potentially saving production costs and increasing the accuracy of the casting. If an example of the item to be sand cast already exists, it can easily be scanned to create the 3D model.

    Once the program for producing the sand mold and core is perfected, it can be reproduced as many times as desired. Such sand casting equipment is a growing part of the metal casting industry. The sand casting advances of today would no doubt amaze the master sand casters from a hundred years ago — not to mention those of a thousand years ago!

    Why Do Some Cast Items Require Machining?

    In some cases, an item produced through the sand casting process requires machining, painting, or another process to bring it to completion. Oftentimes, the item will have extraneous material necessary to make a good cast but not meant to be part of the finished design. At other times, fine detailing is needed and can be added after the cast is completed. Cast Technologies has a CNC machine shop on-site in order to deliver a finished product that meets your needs. This allows us to serve our customers better, as we take responsibility for all the processes the part requires to meet its design specifications.

  • What is a Foundry
    Jun 23, 2022

    Human beings left the Stone Age behind roughly 4,000 years ago when the Bronze Age began, although some foundries go back even further. The team at Cast Technologies takes great pride in coming from a long line of skilled craftsmen that reaches back to the ancient world. We are today using processes based on the same principles as those used by our ancient ancestors to radically change and modernize the world. While people might think of things like electricity, the printing press and computers as the building blocks of the contemporary world, the truth is our way of life rests to a very large degree on the work of foundries: Automotive, air travel and energy production are just three industries that heavily depend on cast items. You depend on multiple cast items every day of your life.

    Naturally, modern foundries bear little resemblance to the primitive technologies that man invented to make weapons and tools from simple bronze alloys, but the ideas are much the same: Melt a mixture of metals together and pour the liquid into some kind of mold. Making a bronze spearhead uses much the same technology still used for making parts for a power generator.

    The ancients made things like weapons and plows, allowing them to put aside their more primitive stone tools. Today, foundries make an almost infinite number of items we rely on in modern life, including car engines, pipes, chains, aircraft parts, tools and many other metal components. Of course, foundries today aren’t limited to bronze, but can cast countless metal alloys depending on the characteristics required by the finished item. 

     

    How Has Foundry Technology Changed?

    Foundries have evolved considerably, thanks to advances in technology and the science of metallurgy. Initially, charcoal fires were used to power little furnaces hot enough to melt metal, but now gas or electric heat are used to power more advanced furnaces. 

    Early foundries were a dangerous work environment, but modernization and mechanization have made them much less hazardous. For example, pouring molten metals into molds via a robot or other automated equipment is much safer than pouring by hand using a ladle. 

    Another change in foundries involves the methods used to placing the molten metals into molds. Traditional gravity pours are still used, but there are other methods available now, including vacuum or pressurized gas pours.

     

    A Simple Explanation of the Foundry Process

    Imagine you are living a few thousand years ago and you wanted to cast a simple item, such as a flat disk, in metal. The easiest method would be something called sand casting.

    You might start by carving something called a pattern from wood. Once you had your desired shape just as you wanted it, you could sink it into a sandpit and then — very carefully! — you would remove your wooden model from the sand. Done right, this would leave a perfect impression of your wooden model in the sand. 

    Next, you would prepare your metal according to the characteristics you wanted your finished item to have. Perhaps you’d follow the ancient recipe of one part tin to nine parts copper. You’d need a small furnace, a clay melting pot and of course a hot charcoal fire for melting. Yes, primitive charcoal-fired furnaces can indeed get hot enough to melt copper and tin together, although it’s much easier to achieve the necessary temperatures in a modern foundry.

    Once your metals had melted together, you’d carefully pour your mixture into the sand cavity and let the metal cool. Finally, you’d remove the solidified metal disk from the sand. If all went well, you’d have a perfect metal copy of your wooden disk.

    Now let’s imagine you wanted to make a more complex casting. You might want to make your item in two different sections, a top and bottom. This is called a split pattern, and the upper section is called the cope, while the bottom section is called the drag. 

    Even more complex designs can be made using something called a core. The core is inserted into the mold to create a hollow area. 

    Now imagine you needed your item to have a smoother finish. You could smooth it out by sanding or grinding. Today, you might sandblast the surface, sand it or machine it smooth with a grinder. This same general process is used in making everything from the simplest tiny items, such as jewelry, to the most complex and large parts weighing hundreds of pounds, such as wind turbine blades.

    After the item comes out of the mold, further processes may be used if necessary. Cast Technologies has an on-site machine shop to add the finishing touches to any component.

  • Advantages and Disadvantages of Casting Pattern Classes Types
    Jun 23, 2022

    The table shows the advantages and disadvantages of the different classes of pattern equipment used by sand casting process.

     

    Pattern Type
    Advantages Disadvantages
    Wood Loose Low cost to produce. Use to produce plastic patterns. Easily modified. Not suitable for production batches unless converted into plastic before becoming worn. Tend to become inaccurate and to produce poor surface finish.
    Hardwood Inexpensive for small-batch production. Can be used as masters for plastic patterns. Fairly easily modified but expensive if multiple impressions involved. Fair wearing properties. With care, will remain reasonably accurate over fairly long periods. Not suitable for high-volume production.
    Plastic Inexpensive to produce. Urethane technology provides good wearing properties and accuracy. Easily modified depending upon the materials used. Suitable for high-volume production patterns with the same dimensional tolerances as metal patterns. Urethane technology has reduced many of the disadvantages of early plastic pattern materials.
    Metal Excellent wearing properties. High standard of accuracy and stability. Suitable for high-volume production and shell molding. CAD/CAM improvements are greatly reducing cost and lead time requirements. Costly. Difficult to modify. Equipment is less adaptable for movement from one foundry to another.

  • Casting Competition: Sand Castings vs. Permanent Mold Castings
    Jul 22, 2022

    Sand castings or permanent mold castings? Since we offer both casting processes here at Hengchang Foundry, we often get posed this question. What is the difference between these two casting processes and which one is better suited for your application? Let’s clear up the casting confusion with a cursory overview.

    Sand Castings: A one-time sand mold is produced, which may contain one or more impressions of the part. Molten metal is poured into the sand mold, then following solidification and cooling, the sand is broken away and the casting is removed. In most cases, the sand is recycled and reused. So when is sand casting the appropriate method? When the production is suited for low and high volumes, the process is driven by material and mechanical casting property requirements, only moderate surface finishes and dimensional tolerances are needed, low tooling costs are needed, and when size and configurations dictate that the part can only be made as a sand casting. There are additional considerations that may have to be taken into account, and it is recommended that the user consult with the foundry prior to finalizing part design.

    Permanent Mold Castings: Unlike a sand casting, the mold is made from cast iron or steel, allowing for one or more cavities depending on the geometry of the part. The process is best suited for mid to higher volumes, when the part configuration dictates this type of casting, or the process is best suited for the application of the casting. The molds are in, most cases, fully CNC machined with the parting surfaces aligned with a locking system that provides good repeatable casting dimension conditions. When compared to sand castings, permanent mold castings have improved surface finishes, less machining allowances required, and closer net shaped profiles which are made possible by the metal mold configurations. Unlike sand castings, however, permanent mold castings are limited in size and the tooling proves to be more expensive (though part price tends to be lower!). Again, consult with a foundry to determine the right process for your needs!

    Do you better understand the difference between sand castings and permanent mold castings? Have you decided which is better for your specific applications? See our website for more information on.

  • Investment Casting vs. Sand Casting — What’s the Difference?
    Jul 22, 2022

    Several casting methods exist for producing the machine parts required for industrial manufacturing processes, including sand and investment casting . Here, we will explore some key similarities and differences between the two. 

    Sand Casting Process 

    Metalworkers widely use sand casting technology because it is suitable for casting steel, iron, brass, and most nonferrous alloys—as well as for final products that weigh anywhere from less than a pound to thousands of pounds. The sand casting process begins with creating a sand mold. In a traditional foundry, after making the desired pattern or model of the final product from hardwood, urethane, or foam, sand is compacted around it to form the mold. In order to maintain its shape, the sand is initially treated with a bonding agent known as binder, which improves adhesion between its particles. The pattern is then removed by splitting the sand mold apart into two or more sections. These sections are then bound to receive the molten metal through a delivery system referred to as the gating system. After the metal sufficiently cools and solidifies, the final product is recovered by removing the sand through a shake-out process.

    Advantages of Sand Casting 

    Some key benefits of sand casting are outlined below:

    • Low operational costs
    • Can cast ferrous and nonferrous materials
    • Suitable for casting large parts
    • Relatively easy to change the design of the mold
    • Fast lead time 

    Investment Casting Process

    Also known as lost wax casting, investment casting technology is reliable for complex and detailed components. Metalworkers use it to create a final product with a near-net shape, leading to lesser material, machining, and labor costs compared to other forms of metal casting. 

    The investment casting method begins with molding wax into the desired cast and coating it with refractory material, such as ceramic. Applying heat melts out the wax, leaving an empty shell with the void to be filled shaped in the geometry desired. Molten metal is then introduced into this pre-heated shell. As soon as it suitably cools and solidifies, it is recovered by shattering the shell. 

    Advantages of Investment Casting 

    Some major advantages of employing investment casting include:

    • Capable of casting ferrous and nonferrous materials 
    • High levels of accuracy 
    • Can cast thin-walled products with complex designs 
    • Smooth surface finishing 
    • Lesser need for extra machining and finishing  

    Investment Casting vs. Sand Casting Comparison

    Both investment and sand casting have experienced significant improvements over the years—geared at minimizing the quantity of metal used and reducing extensive finishing and machining requirements. Although they are similar in some ways, some notable differences exist between them. 

    Similarities

    A few similarities between both casting methods include:

    • They can both cast ferrous and nonferrous materials 
    • Metalworkers shatter the molds to recover the finished product in both methods
    • They both require a molten metal delivery system  

    Differences

    There are some fundamental differences between investment and sand casting, including:

    • Casting time
    • Quality of appearance
    • Materials
    • Design
    • Dimensional tolerance
    • Range of products
    • Mass production  

    Casting Time

    The molding cycle for sand casting is short, while the investment casting process takes longer.

    Quality of Appearance

    The final product from sand casting is usually rough depending on the sand used. Other defects include clip sand, sand wash, and gas holes. Meanwhile, products from investment casting are significantly smoother.

    Materials

    Materials needed for investment casting, such as paraffin wax, sodium silicate, etc., cost more than those required for sand casting (sand, binder, etc.). Sand casting is relatively cheaper.

    Design

    Metalworkers can achieve more complex designs with investment casting, while sand casting may require extra tapering and machining to achieve the desired geometry. Sand casting patterns are more cost effective and require much less time to modify than the tooling required to manufacture investment castings, if design changes are required during a production run.

    Dimensional Tolerance

    With the high dimensional tolerance of investment casting (CT 4-6), finished parts can have thin walls, while finished parts from sand casting have a minimum wall thickness of 3 to 5mm because of their lower-dimensional tolerance (CT 10-13).

    Range of Products

    The adaptability of sand casting is broad, and as a result, it can be used for a wide range of castings, including ductile iron, grey iron, steel, aluminum, etc. Although investment casting can be used for other metallurgies, they are generally suitable for steel castings.

    Mass Production 

    Since investment casting can ensure consistency, it is suitable for mass production. Sand casting, however, cannot promise such consistency. Hence, mass-producing finished parts are more challenging using sand casting methods.

    Which Method Is Right For You?

    Knowing the appropriate method requires you to put some factors into perspective. Different materials are well suited for different products. Therefore, you must know the materials suitable for your product since it can help you determine the better-suited casting method. You must also consider the possibility of mass production and that each casting method requires different cycle times to inform your decision. Additionally, the overall casting cost must be considered. Ultimately, it is up to you to select the method which overall casting benefits for your project or application.

  • How to Clean a Cast Iron Pan
    Sep 05, 2022

    Cast iron Pan are very popular. Most metal pans are made of Grey iron. How to clean it is the key to the life of the IRON Pan. Here some tips for reference. Now that the crusty food is gone, a simple baking soda scrub will restore it to its former, flavorless, glory. Use baking soda and water in a 2:1 ratio, it should form a thin paste. Scrub this into the pan with a soft or plastic bristle brush and then allow the paste to sit for two to five minutes. Just like the stinky aromas in your refrigerator, the baking soda neutralizes the leftover flavor that may be in the top layer of your cast iron.

    Then rinse the paste out of the skillet and wipe with a paper towel or a kitchen rag. If you went really crazy with the fried catfish or boiled clams in the skillet and you're about to make Grandma's pear upside down cake in it, go ahead and give the skillet another baking soda bath. If the flavors of the previous dish weren't too strong, skip the second scrub and follow these steps to re-season your skillet.

  • Factors Affecting Graphitization Of Cast Iron
    Sep 05, 2022

    The formation process of graphite in cast iron is called graphitization process.

    It can be divided into three stages:

    1.Liquid phase hypoeutectic crystallization stage.It include the direct crystallization of primary graphite from the liquid phase of hypereutectic components, the crystallization of austenite from the liquid phase of eutectic components and the graphite formed by primary cementite decomposed during high temperature annealing.

    2.Eutectic transition phases between hypoeutectoid transitions.It include the direct precipitation of secondary graphite from austenite and the graphite formed by the decomposition of secondary cementite in this temperature range.

    3.Co-folding transition stage.Including the eutectoid graphite formed during the co-folding transformation and the graphite formed by the decomposition of the eutectoid cementite during annealing.

    The structure of cast iron depends on the degree of graphitization. In order to obtain the required structure, the key is to control the degree of graphitization. Practice has proved that many factors such as the chemical composition of cast iron, the cooling rate of cast iron crystals, the overheating and standing of molten iron, etc., all affect graphitization and the microstructure of cast iron.

     

    Factors affecting graphitization of cast iron:

    1.Influence of chemical composition.

    2.Influence of cooling rate.

    3.The effect of overheating and high temperature standing of cast iron.

  • How Will China’s New $44 Billion Stimulus Impact Steel Prices?
    Sep 09, 2022


    A few days ago, China’s State Council announced more stimulus policies. The new measures included an additional 300 billion yuan ($44 billion) in quotas for infrastructure spending and investments by banks. This was in addition to the 300 billion yuan announced at June-end. However, the only real question regarding the stimuli is looking at everything happening with steel and iron ore prices: will it help? Most initial reports suggest that the move may give impetus to steel and iron ore off-take, both of which are in a months-long slump. However, other reports believe these new stimulus actions might not achieve their goals. More specifically, they won’t generate a renewed interest in construction activity in China. As a result, there won’t be much (if any) of a positive impact on the steel sector.

    In 2021, China produced 1.033 billion tons of crude steel. It was the first decline since 2016. Thus far, in 2022, national steel production is down 6.4% year-on-year. The China Metallurgical Industry Planning and Research Institute predicted this at the beginning of the year, stating that China’s 2022 output would slow to 1.017 billion tons. This represents a 1.5% decrease from the year before.

    Steel and Iron Ore Prices Bouncing Back
    Following the recent stimuli announcement, a Bloomberg report stated that China’s raw materials prices, including iron ore prices, had officially steadied. This came after factory activity shrank less than expected in August. Meanwhile, the purchasing managers’ index for steel stayed in contraction, and the pace of its decline narrowed sharply.

    Steel industry experts are hopeful that steel output will increase in September as the country starts to respond to the government stimulus efforts, which will hopefully aid iron ore prices. Some Chinese steel mills have already signaled that production is rising and profit margins are back in positive territory. Industry castings will be back to normal production.
