Investment casting process is suitable for most metal parts.With this process,we could cast many investment castings with different metals and alloys that have high temperature properties for use in a range of applications,and especially suited to small castings ranging from 0.1kg-60kg.
Tongda precision casting focuses on the techniques of silica sol, water glass，shell mould and lost-foam castings. The materials we are dealing with are stainless steel, carbon steel, alloy steel, ductile iron, grey iron and so on.
Casting, also called pouring, is the most important process during steel castings manufacturing. If this process is not properly managed, the scrap rate of the steel castings will be very high. Thus, during steel casting production process, our investment casting factory builds strict requirements and attention matters on every operations. The workers are also trained with all announcements before starting casting process.
When making stainless steel investment castings,we often meet shell expansion defect.Shell expansion defect is caused by volume solidification mode of modular cast iron ally and graphitization expansion in the process of eutectic transformation.Below Tongda will talk about how we solve this problem.
A PO Procedure starts from inquiry to PO closed.To make this process standard,we have a strick procedure to follow. Tongda mainly exporting investment castings to overseas customers,such PO procedure will help us to have a better communication with our customers.
