resin coated sand casting alloy yacht keel

The Lead Alloy Yacht keel is the bottom-most longitudinal structural element on a vessel. On some sailboats, it may have a hydrodynamic  and counterbalancing purpose, as well. OEM long deep keels are common on traditional yachts. They form part of the hull structure as opposed to being bolted on to the hull. They provide plenty of strength and stability but are less efficient than modern designs.

Hengchang is custom lead alloy yacht keel manufacturer. We use resin sand casting process to produce it. Resin sand is a type of quartz sand that is mixed with a resin material.  The chemical reaction created by the resin helps to bind and stiffen the quartz sand to make solid, hard and strong molds. 。 The resin sand can be used to create just a part of the mold, or the entire mold material. The mold can create 3D products in a variety of shapes, configurations and sizes.  Once the mold is made, materials are poured into the mold as the sand’s refractory properties help the mold remain stable.  Then the sand is removed through a shakeout process as the metal is then cut, ground, finished and assembled into the final product. 

A wide variety of metals can be used in resin sand cast molding due to the sand’s tolerances to high temperatures.  So iron, titanium and nickel alloys can be used in this process. 

Lead alloy casting:

- weight: 0.5-2000KG

- technology: vacuum casting, resin sand, shell molding

- application: Water heating, air conditioner, pump, valve, other mechanical field
