Custom Auto Parts Disc Brake

Grey Iron disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a disc or a "rotor" to create friction . This action slows the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary. The energy of motion is converted into waste heat which must be dispersed.

Hydraulically actuated disc brakes are the most commonly used form of brake for motor vehicles, but the principles of a disc brake are applicable to almost any rotating shaft. The components include the disc, master cylinder, caliper (which contains cylinder and two brake pads) on both sides of the disc.

OEM & ODM Cast Iron Disc Brakes from Hengchang Foundry

Hengchang is the leading producer of gray, ductile iron in China, melting more than 6000 tons per year, with more than 15 years experience.We produce custom grey iron disc brakes by Resin Sand Casting.In the resin sand casting process, resin and sand are first mixed together. Following that, the mixture is self-hardened through chemical reaction to produce exceptionally hard molds.

• Resin sand casting typically produces accurate results that are superior to other sand-casting methods.
• This process also results in increased surface strength when compared to other sand-casting options
• The nature of resin sand casting can help reduce defects such as sand holes, air holes, and shrinkage.
• More flexibility with sizing
• Resin sand casting can produce large iron castings. These castings can range from dozens of kilograms up to several tons.

Gray Iron Applications:

The following is the common application for each degree of grey cast iron for your reference.

HT100 (GG10, EN-GJL-100):
For small loads, the friction and wear no special requirements for important castings, such as protective cover, cover, oil pan, hand wheels, frame, floor, hammer, small handle, etc.

HT150 (GG15, EN-GJL-150):
Under moderate load of castings, such as the base, frame, box, knife, bed, bearing seat, table, wheels, cover, pump, valve, pipe, flywheel, motor blocks and other

HT200 (GG20, EN-GJL-200):
Requirements withstand greater load and a certain degree of tightness or corrosion resistance of the more important castings such as cylinder, gear, base, flywheels, bed, cylinder block,cylinder liner, piston, gear box, brake wheel, coupling Plate, medium pressure valve, etc.

HT300(GG30, EN-GJL-300)

Under high load, wear and high air tightness important castings, such as heavy machine tools, shears, presses, automatic lathe bed, frame, high-pressure hydraulic parts, piston rings, force large gear, Cams, bushings, large engine crankshaft, cylinder block, cylinder liner, cylinder head....

The Quality Control 

Quality is the soul of our foundry, we are equipped with a complete metallurgical laboratory to determine the chemical and mechanical characteristics of each melt and to analyse the metallurgic condition of the molten metal before pouring. Microsections are examined under the microscope to obtain final information.we issue related reports for each delivery part on customers' demand.
