Shell Casting

Features of Shell Mold Casting

1. This shell casting technology can reduce the quantity of the foundry sand and obtain a clear outline,smooth surface and precise size.It does not need machining process or only a small amount of machining.
2. The shell mold casting is especially suitable for producing various alloy castings with larger batch,high dimensional accuracy and complex shapes,but the manufacturing cost is relatively higher.
3. This shell casting process can achieve fully automation for mass production.
4. The characteristics of the shell mold casting are high productivity,low labor costs and excellent surface finishes.

Description

Shell casting puts resin coated sand on the preheated metal template with mould ,makes the resin melt and form a layer of shell.It achieves the desired moisture and rigidity after melting,drying and hardening.

The shell mold casting is applied to the automobile,train,shipbuilding,electronic and semiconductor industries.The material can choose a variety of copper alloys,aluminum alloy,zinc alloy,ductile iron,gray iron,stainless steel and carbon steel.

Shell casting is a metal casting process similar to sand casting,in that molten metal is poured into an expendable mold.However,in shell mold casting,the mold is a thin-walled shell created from applying a sand-resin mixture aroud a pattern.This casting process requires the use of a metal pattern,sand-resin mixture,dump box and molten metal.

Shell Casting Process

The shell mold casting process is composed of following steps:

Patten creation

A two-piece metal pattern is set up in the shape of the desired part,typically from iron or steel.Other materials are also can be used,such as aluminum for low volume production or graphite for casting reactive materials.

Mold creation,mold assembly

After the molten metal is cooled,the mold can be broken and the castings can be removed.Trimming and cleaning processes should removed any excess metal from the feed system and any sand from the mold.
