Integrated vacuum debinding and sintering furnace is specially designed for metal injection molding (MIM).
Overview
Integrated vacuum debinding and sintering furnace is specially designed for metal injection molding (MIM).
The following functions could be carried out in the furnace: negative pressure de-waxing, pressure de-waxing with H2, vacuum sintering, atmosphere sintering, partial pressure sintering and cooling.
The debinding function is suitable for following kinds of binder: wax, stearic acid, and oleic acid.
Advantages
Our integrated vacuum debinding and sintering furnace has the following advantages.
① Improve production efficiency: Since the vacuum debinding and sintering integrated furnace can complete debinding and sintering in the same equipment, the switching time in production is reduced, and the production efficiency is improved.
② Reduce energy consumption: In the process of debinding and sintering, the furnace uses advanced heat preservation technology to effectively reduce energy consumption.
③ Convenient operation: The integrated vacuum debinding and sintering furnace adopts advanced control system, which makes the operation more convenient and reduces the labor intensity.
④ Optimize the working environment: Because the vacuum environment is used in the sintering process, the emission of harmful gases can be effectively reduced, thus optimizing the working environment.
