Abstract

The invention discloses an automobile chassis guard plate and a manufacturing method thereof. The preparation method mainly comprises the following steps of: firstly preparing a material A and a material B; drying and then mixing according to a proportion; adding the mixture into a warmed injection molding machine; setting injection pressure values, speed values, injection time values and injection glue amount values of different sections of the injection molding machine, and meanwhile, setting a final dwell pressure value and a final dwell speed value so as to enable the best injection molding technology to be realized, so as to obtain the final qualified product. According to the automobile chassis guard plate and the manufacturing method thereof, physical performance defects that the injection molding automobile chassis guard plate is easy to pull apart and crack during molding, is poor in toughness, low in intensity and the like are solved; meanwhile, the injection molding technology is stable; products obtained by using the method are stable in quality; the production efficiency is improved; and the production cost is lowered.

Description

technical field [0001] The invention relates to an automobile chassis guard plate 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 an automobile chassis guard and its manufacturing method. Physical performance defects such as poor...
