Plastic socket, manufacturing method thereof and application of plastic socket on automobile

Abstract

The invention discloses a plastic socket, a manufacturing method thereof and application of the plastic socket on an automobile. The manufacturing method mainly comprises the steps of: modifying nylon PA66, then adding the nylon PA66 as a raw material into a heated injection machine, and obtaining a final accepted product by setting the injection pressure, speeds, injection time and injection glue quantities of different sections of the injection machine and simultaneously setting that the final dwell pressure and pressure holding speed achieve the optimal injection technique. The socket disclosed by the invention is easy to mold in an injection manner, easy to demold, stable in machining technology, and high in qualification rate; the production efficiency is improved; the production cost is reduced; and the injected product socket is high in surface gloss, good in fire resistance, good in toughness, high in strength and stable in performance, and can be applied to the automobile.

Description

Background technique [0001] The invention relates to the field of engineering plastics, in particular to a plastic socket, its manufacturing method and its application in automobiles. Background technique [0002] With the development of the economy, the automobile industry is also developing rapidly. Most of the materials used in many parts of the automobile are engineering plastics, of which nylon is used in a large amount, and the requirements for the performance of nylon materials are getting higher and higher. While maintaining its own performance, it must be able to overcome its own shortcomings, so it needs to be modified. In the prior art, it is improved by adding additives such as tougheners and flame retardants to nylon. However, after various materials are mixed, the dispersibility of each component is poor during the blending process, the compatibility between each component is poor, the strength, toughness, and corrosion resistance are insufficient, the material...

AI Technical Summary

Problems solved by technology

[0003] In order to alleviate the deficiencies and defects of the prior art, the object of the present invention is to provide a plastic socket used in automobiles and a manufacturing method thereof. Difficult demoulding, fracture, poor toughness, low strength and other physical defects. At the same time, the injection molding process is stable, and the product quality is stable, which improves production efficiency and reduces production costs.
