Processing Technology of Sand CastingSand casting process is a casting method in which sand is used as the main modeling material to prepare molds.

What is Cold ForgingForging is one of the oldest metal forming processes known to man. The process of forging metal involves tapping or hammering the workpiece on or on the mold, template, or fixture.

The role of heat treatment is to improve the mechanical properties of materials, eliminate residual stress and improve the machinability of metals.
