采用如下生产流程：通过固定加料方式和弹簧加料法将粒料加入挤出机中，进行挤出造粒。在通过胶带式运输机运送至注塑车间，物料经过注塑机注射成型，再经过表面处理、涂装工艺和质量检验以及最后的废品回收后，最终得到保险杠成品。期间，也尽量考虑了低成本、高性能、低污染、可循环的理念对车间较为合理的设计，并且绘制了工艺流程图和生产车间平面布置图。

500,000 sets of automobile bumper's workshop process design
Abstract: According to the order of the design task order, this design is the annual output of 500,000 sets of car bumper workshop for the design process. By referring to a large amount of literature, I clear about the bumper materials and the formula, as well as the basic material such as PP and filler POE's property. Also, I also chose a more mature technological process, equipment, and etc, and make a more detailed description for device models, equipment structure as well as material balance in the production process.
Adopting the following production processes: putting the pellets into the extruder by Fixed loading and spring feeding to do the extrusion granulation. Through the belt conveyor, send to the injection molding workshop, material through the injection machine for the injection molding, after surface treatment, coating process and quality inspection and the final step recovery unit, finally got bumper products. During the period, I also consider the idea of low cost and high performance, low pollution and recyclable to make the design of workshop more reasonable, as well as draw the process flow diagram and layout plan of production workshop.
