Abstract

The mixed defatting stove includes one stove body with a solvent inlet in the lower part and connected via a pump to a solvent storage device, a solvent outlet, a protecting gas inlet in the lower part, a gas exhaust port in the upper part, a solvent vapor inlet in the upper part and connected to solvent distiller, and has a heater on the side wall of the stove body, a blower on the upper part of the stove body to homogenize gas inside the stove, and an atomizer on the upper part of the stove and connected via a pump to a catalytic defatting acid storing device outside the stove body. The mixed defatting stove may meet the requirement of different defatting processes, including single or simultaneous solvent defatting, vapor defatting, condensed vapor defatting, catalytic defatting and siphonic defatting.

Description

technical field [0001] The invention relates to a device for degreasing powder injection molded parts, in particular a hybrid degreasing furnace for such parts. The invention also relates to a hybrid degreasing process using the furnace. Background technique [0002] Degreasing method definition advantage shortcoming thermal degreasing Heat the PIM forming blank to a certain temperature to make the binder Evaporation or thermal decomposition produces gas small molecules, gas small Molecules are transported to the shaped body by diffusion or osmosis surface. Then the binder decomposition gas escapes from the surface of the forming billet face into the external atmosphere Simple process, low cost, investment Less capital, no ring environmental pollution Degreasing speed slow, easy labor birth defect, only suitable for Small pieces so...
