Problems solved by technology

[0005] The purpose of the present invention is to solve the shortcomings in the prior art. Firstly, the raw materials are detected to avoid defective products; then the metal powder raw materials and binder are uniformly mixed and injected into the mold for molding processing, and the rough workpiece is quickly obtained. ; Combining rough workpieces for sintering processing to obtain sintered workpieces; then deep processing of sintered workpieces to quickly and effectively complete the production and processing of products. The entire production and processing process is scientific and can effectively complete the processing and production of complex MIM parts to solve The existing MIM lock frame and lock cylinder parts proposed in the above background technology have complex product structures, and the problem that the mold cannot be formed and processed at one time

Abstract

The invention discloses a machining method for a complex MIM part. The method comprises the following steps of S1, raw material inspection, S2, mixing and injection molding, S3, sintering machining, S4, deep machining treatment, and S5, product inspection and packaging, specifically, carrying out randomly selecting and inspecting on all products, and packaging the randomly selected products afterthe randomly selected products meet the qualified rate of 100%, and storing the packaged products in a shipment warehouse. According to the machining method for the complex MIM part, firstly, a raw material is detected, and defective products are avoided; the metal powder raw material and a binder are uniformly mixed and injected into a mold for molding so as to quickly obtain rough blank workpieces; the rough blank workpieces are combined and sintered to obtain a sintered workpiece; and then the sintered workpiece is subjected to deep machining treatment, so that production and machining of the product are rapidly and effectively completed, the whole production and machining process is scientifically designed and treated, and machining and production of the complex MIM part can be effectively completed.

Description

technical field [0001] The invention belongs to the technical field of MIM part processing, and more specifically relates to a complex MIM part processing method. Background technique [0002] Sintering, which refers to transforming powdery materials into dense bodies, is a traditional process. People have long used this process to produce ceramics, powder metallurgy, refractory materials, ultra-high temperature materials, etc. Generally speaking, the dense body obtained by sintering after the powder is shaped is a polycrystalline material, and its microstructure is composed of crystals, glass bodies and pores. The sintering process directly affects the grain size, pore size, and grain boundary shape and distribution in the microstructure, which in turn affects the properties of the material. Macroscopic definition: At high temperature (not higher than the melting point), the solid particles of ceramic green bodies are bonded to each other, the grains grow, the voids (pore...
