Rework and Rejection Rate of Casting Process
Problem Description – Out of our total rejections and rework of about 10%, about 80% rework and rejections are due to casting defects. We are doing brass casting by Gravity Die Casting Process, where dies are filled up with molten metal either by hand or by Die Casting Machines. We analyze the material composition regularly, maintain material temperature, provide gas vents in the dies, etc. But to reduce the rejection and rework rate is a big challenge.
Development of new product ranges and die designing is also one of the challenging tasks in this department.
AIM – To reduce rework and rejection rates.
To develop a system of Simulation of the flow of liquid metal before manufacturing a new Die.
