Abstract

The invention discloses an automobile wiring harness plastic protective frame and a manufacturing method thereof. The manufacturing method mainly includes: adding dried proportioned raw materials in a warmed-up injection molding machine, setting injection pressure, speed, injection time and injection glue quantity of different sections of the injection molding machine, simultaneously setting final holding pressure and holding speed which arrive optimum injection technology and obtaining a final acceptable product. The automobile wiring harness plastic protective frame and the manufacturing method of the automobile wiring harness plastic protective frame overcome shortcomings that the injection-molded automobile wiring harness plastic protective frame is easy to have while-pulling and crack, poor in toughness and low in strength and other physical properties while being molded, simultaneously are stable in the injection technology and quality of the obtained product, improve productionefficiency, and reduce production cost.

Description

Background technique [0001] The invention relates to a plastic protective frame of an automobile wiring harness and a manufacturing method thereof, belonging to the technical field of automobile 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...
