Key points of metal lost wax molding

Now to say the process is: lost wax casting (also known as lost wax method), is a kind of less cutting or no cutting precision casting process. Its application is very extensive. It can not only be used in all types, all kinds of alloy precision casting, and production of casting dimension precision, surface quality than other precision casting method to high, and other precision casting method is difficult to cast the complex, high temperature resistant, not easy machining of castings can be used lost wax casting.

Process costs: tooling costs (low - middle), single piece costs (middle - high), labor charges (high)

Typical products: the use of a very wide range, such as building structure, consumer electronics, aerospace, jewelry, urban sculpture, etc.

Production is suitable for medium and large scale production

Quality: high precision forming surface, especially suitable for forming metal parts with complex shape.

Speed: the cycle is long (24 hours).

Applicable Materials

Not only for all ferrous and non-ferrous metals, but also can be used for the traditional cast materials such as super alloy. The most commonly used materials are: low alloy steel, stainless steel, aluminum, titanium, zinc, copper, nickel alloys and precious metals.

Design considerations

The part thickness is determined by the alloy material used.

1 aluminum alloy and zinc alloy parts wall thickness should be controlled between 1.5mm-3mm (0.079-0.118in)

2 steel and copper alloy parts wall thickness should be greater than 3mm (0.118in)
