Manufacturing process of instrument carriage with raw materials containing ACS (acrylonitrile-chlorinated polyethylene-styrene) resins

Abstract

The invention discloses a manufacturing process of an instrument carriage with raw materials containing ACS (acrylonitrile-chlorinated polyethylene-styrene) resins. The manufacturing process is characterized by respectively drying a material A and a material B at 100-120 DEG C for 3-5 hours, then uniformly mixing the material A and the material B according to parts by weight and then granulating the material A and the material B and remixing and then granulating the granulated material A and material B; and adding the obtained granulated materials to an injection molding machine to be molded and demolding the materials, thus obtaining the instrument socket, wherein the material B contains the ACS resins. The manufacturing process has the beneficial effects that the injection-molded instrument carriage for a car easily suffer from such physical property defects as drag marks, breakage, poor toughness and low strength during molding; and meanwhile, the injection molding process is good in stability, the obtained product has stable quality and high surface gloss, the production efficiency is improved and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a manufacturing process of an instrument bracket whose raw material contains ACS resin. Background technique [0002] With the progress of society, the use of cars is increasing. [0003] In the prior art, the instrument brackets used in automobile manufacturing are mainly made of nylon materials, which are compounded by adding a toughening agent. After mixing various materials, the dispersion of each component is not good during the blending process, and the components are compatible. Poor performance, insufficient strength, toughness, and corrosion resistance, high material cost, difficult demoulding, poor surface gloss, poor processing performance, and unstable product quality. Contents of the invention [0004] In order to alleviate the deficiencies and defects of the prior art, the object of the present invention is to provide a manufacturing process for instru...

AI Technical Summary

Problems solved by technology

[0004] In order to alleviate the deficiencies and defects of the prior art, the object of the present invention is to provide a manufacturing process for instrument brackets whose raw materials contain ACS resin, which solves the problem that the instrument brackets used for automobiles in injection molding are prone to whitening during molding. , fracture, poor toughness, low strength and other physical defects. At the same time, the injection molding process is stable, the product quality is stable, the surface gloss is high, the production efficiency is improved, and the production cost is reduced.
