Problems solved by technology

[0002] The metal frame is a metal frame made by injection molding. Since the metal frame made by injection molding has a small gap, when a metal frame with a large gap is required, the injection molding method cannot To meet the existing demand, and with the continuous reduction of the total amount of metal resources, the price of metals continues to rise, so the use of injection molding for production will increase the consumption of enterprise costs and reduce the benefits of enterprises

Abstract

The invention discloses a manufacturing method of a powder metallurgy metal frame, which uses several aluminum powders, plasticizers, carbon powders, alloy reinforcing elements, nickel powders, iron powders, and paraffin powders, and the balance is copper powders, and the materials are mixed by a mixer , to form a mixed substance, and then make the mixed substance adhere to the surface of the metal frame, and finally form the metal frame by sintering. The present invention uses powder metallurgy to make the metal frame, which can form a porous or semi-dense metal structure, reduces the consumption of enterprise costs, and thus improves the revenue benefit of the enterprise.

Description

technical field [0001] The invention belongs to the technical field of powder metallurgy, and in particular relates to a manufacturing method of a powder metallurgy metal frame. Background technique [0002] The metal frame is a metal frame made by injection molding. Since the metal frame made by injection molding has a small gap, when a metal frame with a large gap is required, the injection molding method cannot To meet the existing demand, and as the total amount of metal resources continues to decrease, the price of metals continues to rise. Therefore, the use of injection molding for production will increase the consumption of enterprise costs and reduce the benefits of enterprises. Contents of the invention [0003] The present invention overcomes the deficiencies of the prior art, and provides a method for manufacturing a powder metallurgy metal frame. The powder metallurgy method is used to make the metal frame, which can form a porous or semi-dense metal structure...
