DESCRIPTION
Degreasing and pressure sintering of powder metallurgy products such as CNC inserts, cermets, hard alloys, copper-based alloys, iron-based alloys, titanium carbide, etc., improve bending strength, hardness, increase density, and obtain excellent microscopic metallography organization. The equipment integrates negative pressure degreasing, H2 micro-pressure degreasing, atmosphere sintering, vacuum sintering, pressure sintering and rapid cooling in a single furnace, which effectively improves production efficiency and reduces energy consumption. Stable performance and low production cost.
