The vacuum pressure sintering furnace is a horizontal resistance heating furnace with multiple independent control loops to ensure high temperature uniformity.
The entire process is controlled by SIEMENS S7-1500 PLC and 15-inch touch screen to realize temperature, heating rate, insulation time and gas flow and pressure automation control, monitoring, tracking and recording, self-diagnosis, and fault handling in all process steps.
This pressure sintering furnace is mainly used for degreasing, sintering, vacuum adjustment, pressure densification, and rapid cooling of high-performance powder metallurgy (hard alloy, etc.) materials in a single sintering cycle.
