[0002] The debinding sintering furnace is a crucial process test instrument in the field of material science and metallurgical engineering technology. Debinding, as a key step in the powder metallurgy process, refers to the process in which the fat added to the pressed green body must be removed before sintering. Sintering is the process of combining metal or ceramic particles into a hard material at high temperature. In the debinding sintering furnace, this process is achieved through a high temperature environment, which causes surface diffusion and solid-state reaction between particles to form a dense structure.

[0003] At present, most of the existing titanium alloy 3D metal printing on the market directly adopts vacuum sintering. During the sintering process, the volatilized resin of the material runs into the heat insulation screen or vacuum chamber and vacuum system. Long-term use will cause damage to the sintering design. In view of this, we propose a degreasing sintering furnace. Utility Model Content
