Abstract

The invention discloses a wiring harness protective plate and a manufacturing method thereof. The manufacturing method mainly comprises the following steps of: adding dried and mixed raw materials into a heated injection molding machine; setting the injection pressures, speeds, injection time and injection rubber amounts for different sections of the injection molding machine; and setting a last pressure preserving pressure and pressure preserving speed for reaching an optimal injection molding process to obtain a finally-qualified product. According to the invention, the physical property defects of deformation, fracture, poor toughness and the like which occur easily during molding of an injected-molded wiring harness protective plate are overcome; and meanwhile, an injection molding process is stable, the quality of an obtained product is stable, the production efficiency is increased, and the production cost is reduced.

Description

Background technique [0001] The invention relates to a wire harness guard plate and a manufacturing method thereof, belonging to the technical field of auto parts. Background technique [0002] The traditional automotive wiring harness is fixed on the car body by buckles. In order to avoid interference between the wiring harness and other parts, the size of the wiring harness needs to be strictly controlled. This method is easy to cause the deviation of the wire harness, the size of the wire harness is not easy to control, and the size may be too short, which affects the assembly of the wire harness. In the case of forced assembly, the tensile stress generated on the wire harness is large, and the wire harness is easily damaged. Affect the performance of the car, and even affect driving safety when serious. 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 wire harnes...
