Abstract
The invention relates to an aluminum alloy injection molding feed, an aluminum alloy injection molded part and a preparation method. The aluminum alloy injection molding feed includes aluminum alloy powder and a molding agent in the following mass percentages: 85% to 88% of the aluminum alloy powder, and 12% of the molding agent %~15%; Among them, the molding agent includes the following components in parts by mass: 6-8 parts of paraffin wax, 7-9 parts of ethylene-vinyl acetate copolymer, 8-10 parts of high-density polyethylene, 8-10 parts of stearic acid 10 parts, 3-5 parts of polyethylene glycol and 65-75 parts of polyoxymethylene. The above-mentioned aluminum alloy injection molding feed, aluminum alloy injection molded parts and preparation methods can be applied to the production of aluminum alloy products with complex structures that are feasible for injection molds, and have changed the shortcomings of traditional aluminum alloys such as difficult processing, long processing cycle and high processing cost. It greatly reduces the production and processing costs of complex aluminum alloy parts, innovates the production mode of the entire aluminum alloy industry, and improves the technological innovation and production level of the domestic manufacturing industry.
Description
technical field [0001] The invention relates to metal injection molding technology, in particular to an aluminum alloy injection molding feed, an aluminum alloy injection molded part and a preparation method. Background technique [0002] With the continuous advancement of social science and technology and the vigorous development of global industrialization, powder metallurgy industry has developed rapidly due to its many advantages, and its technology has been widely used in military, transportation, machinery, electronics, aerospace, aviation and other fields. [0003] MIM (Metal Injection Molding, Metal Injection Molding) feeding is the core process of metal injection molding products. Mixing at time and temperature, and then through screw extrusion, cutting and granulation, to make injection molding feed. [0004] Aluminum alloy material, because of the finished parts, the density is low, but the strength is relatively high, close to or exceed high-quality steel, good ...
