Abstract

The present invention discloses a vehicle fuse box upper cover and a manufacturing method thereof. The manufacturing method mainly comprises: preparing a material A and a material B, drying the materials, mixing the materials according to a certain ratio, adding the mixed material to a heated injection molding machine, setting injection pressures, speeds, injection times and glue injection amounts at different segments of the injection molding machine, and setting a final packing pressure and a packing speed to achieve an optimal injection molding process so as to obtain the final qualified product. According to the present invention, physical property defects such as easily-appearing white drawing, fracture, poor toughness, low intensity and the like during molding of the injection molding vehicle fuse box upper cover are solved, the injection molding process is stable, the obtained product has stable stability, production efficiency is improved, and production cost is reduced.

Description

technical field [0001] The invention relates to an automobile fuse box upper cover and a manufacturing method thereof, belonging to the technical field of automobile manufacturing. Background technique [0002] Nylon has the advantages of excellent toughness, self-lubrication, wear resistance, chemical resistance, gas permeability, oil resistance, non-toxicity and easy coloring, so nylon is widely used in industry. With the progress of society, The use of automobiles is increasing. Most of the parts of automobiles are made of nylon. The plastics in the prior art often have disadvantages such as inconvenient assembly, inaccurate positioning, unstable connection, insufficient connection strength, and poor contact performance. Contents of the invention [0003] In order to alleviate the deficiencies and defects of the prior art, the object of the present invention is to provide a car fuse box top cover and its manufacturing method. The invention solves the problem that the in...
