Abstract

The invention discloses a passenger car access door material and a manufacturing method thereof. The manufacturing method mainly comprises the following steps: adding dried proportioned raw materials into a heated injection molding machine; and setting the injection pressure, speed, injection time and rubber injection amount at different sections of the injection molding machine, and setting the final dwell pressure and dwell speed to achieve the optimal injection molding technique, thereby obtaining the end qualified product. The invention overcomes the defects of high whitening and cracking tendency, poor toughness, low strength and other physical properties in the passenger car access door injection molding process; and meanwhile, the injection molding technique has the advantage of high technical stability and stable product quality, enhances the production efficiency and lowers the production cost.

Description

Background technique [0001] The invention relates to a passenger car inspection door material and a manufacturing method thereof, belonging to the technical field of automobile manufacturing. Background technique [0002] With the rapid growth of the national economy, the pace of urbanization in my country is also accelerating, and the number of cars owned is also increasing. However, the maintenance of passenger cars must be rigorous and meticulous. The existing passenger car inspection doors are complex and easy to deform. It is inconvenient and the visual effect is not good. At the same time, it is easy to affect the quality of bus maintenance and reduce the efficiency of bus maintenance. Contents of the invention [0003] In order to alleviate the deficiencies and defects of the prior art, the purpose of the present invention is to provide a passenger car inspection door material and its manufacturing method. The invention solves the problem that the injection molded pa...
