Metal Casting Processes

Metal casting is an essential process in the manufacturing industry, complex shape and structure can be formed through casting.

This is a aluminium motor cover.

Die Casting

High pressure die casting is shortened as die casting. It is a metal forming process through high pressure die casting machine and molds.

By precision molds and machine, good surface roughness and complex shapes can be reached.

Gravity Casting

When it comes to Gravity casting, it is also called as Permanent Mold Casting. The molten metal is poured from a furnace into a steel mold under the force of earth gravity.

By controlling the flow speed and direction of molten metal, better structure and performance can be obtained.

The stainless steel lost wax parts - investment castings.

Investment Casting

Lost wax casting is another name of Investment casting. From wax to molds, complex structure and fine surface can be done.

It’s used in various industry such as machinery, equipment, aerospace, automotive etc.

Sand Casting

Green sand, resin sand and pre-coated sand casting are mostly used. Through mold and sand for shaping, melted metal is poured into the cavity to get the parts.

It’s with low cost and wide application, however, surface is rough and complex shape can not produce
