Bathtub Moulding

Heat treatment of molds during the manufacturing process is a process that most molds have used for a long time. From the surface treatment method, it can be divided into: chemical method, physical method, physical chemical method and mechanical method. , Extend delivery time and increase mold manufacturing cost. Since the 1970s, the idea of ​​pre-hardening has been proposed internationally.　　

Mold manufacturing precision: uneven and incomplete structure transformation and excessive residual stress formed by heat treatment cause mold deformation during processing, assembly and mold use after heat treatment, thereby reducing mold accuracy and even scrapping.　　

It is the heat treatment technology and the mold quality that have a very close relationship, which makes these two technologies mutually promote and improve together in the modernization process.　　

Hardened film deposition technology is currently more mature CVD, PVD. To replace other materials, thereby reducing manufacturing costs. Surface treatment technology can often get twice the result with half the effort, which is the reason why surface treatment technology has developed rapidly.　　

The use of Bathtub Moulding materials can simplify the mold manufacturing process, shorten the mold manufacturing cycle, and improve the mold manufacturing accuracy. Since the 1980s, the rapid development of international mold heat treatment technology has been vacuum heat treatment technology, mold surface strengthening technology and mold material pre-hardening technology. The technical idea introduced from this is to use lower grade materials, that is, through carburizing and quenching
