Perforated Metal Sheets - The Ultimate FAQ Guide

Generally, only two processes: heating and cooling are used for tooling heat treatment.

Heyou supply professional and honest service.

Before heated the precision stamping die, first buried & sealed the mold in the underground pit furnace, secondly add carbon-rich liquid to the furnace; (those liquid can be decomposed into carbon atoms at high temperature and penetrate into the micro-hole mold). Thirdly put the mold in a preheated furnace, wait for a period of time to reach the preset temperature and keep it warm, finally take out the mold.

Place the heated stamping mesh tooling in a cooling tank, the cooling method used here is quenching. There is an aqueous solution or oil in the quenching pool, put the punching die in for a period of time and take it out; then heat it with a high-frequency machine (it is a super high-power machine that changes 50HZ frequency into 200HZ current) to complete the quenching process.

Micro-hole stamping die heat treatment only used heating and cooling method, but generally, there are three processes for heat treatment: heating, heat preservation, and cooling.
