Production of High-Pressure Die-Casting Molds: Application of Vacuum Gas-Quenching Furnaces

2026-10-08 09:10

For high-pressure die-casting molds, strict requirements regarding the degree of deformation and quenching effectiveness are paramount. Furthermore, given the large size of these molds, the processing equipment must meet high load-bearing standards.

SIMUWU’s RVGQ-774 vacuum gas quenching furnace is specifically designed for this type of mold:

1. It features a 6-bar high-pressure gas quenching capability, ensuring optimal cooling rates and superior quenching quality, with the option to upgrade to 12-bar or even higher pressures.
2. The heating chamber supports a maximum load of 1,500 kg, offering robust load-bearing capacity, broad applicability, and a long service life.
3. It utilizes a top-and-bottom opposing gas flow design to minimize the impact of gas quenching on the workpiece, thereby preventing cracking and deformation.
