Abstract
The invention discloses an automotive engine harness guard plate and a manufacturing method thereof. The method mainly comprises the following steps of: adding dried and proportioned raw materials into a heated injection molding machine, setting injection pressure, speed, time and glue quantity of different stages of the injection molding machine, setting final protective pressure and protective pressure speed to achieve an optimal injection molding technology, and thus obtaining a final qualified product. The method overcomes the physical property defects of deformation, breakage, poor toughness and the like when the automotive engine harness guard plate is formed by injection molding; and the injection molding technology has stability, the obtained product is stable in quality, the production efficiency is improved, and the production cost is reduced.
Description
Background technology
The present invention relates to a kind of motor car engine wire harness backplate and manufacture method thereof, belong to machinery manufacturing technology field.
Background technology
Traditional automotive wire bundle is fixed by snap on vehicle body, produces interference for avoiding wire harness to contact with other component, need carry out strict control for the size of wire harness.This mode causes the skew of wire harness easily, beam size is wayward, the short partially situation of size may appear, thereby have influence on the assembling of wire harness, under the situation of assembling by force, the tensile stress that produces on the wire harness is bigger, and wire harness damages easily, have influence on the performance of automobile, when serious even influence driving safety.
