Annual output of 500000 sets of automobile large plastic parts molding workshop process design
Abstract: This topic is the workshop process design of 500000 sets of large injection molding parts for automobiles. The development of the automotive industry continues to develop a large injection molding part of the vehicle, Workshop main products include automotive bumper, dashboard. The process flow is injection molding. And explain the basic material of modified polypropylene chooses， in processing automobile bumper, dashboard, with polypropylene resin mixed with various additives into the mold to make and is thus obtained with excellent rigidity strong plasticity products. The specific technological process includes three stages: preparation, molding process, product modification inspection. Material and auxiliary agent is added into the injection molding machine after drying and mixing, and the material is injected into the injection molding machine, and the final post-processing is finished, and the bumper and the instrument panel are eventually finished. Design content mainly includes the overview, process flow and formulation design, equipment selection, material balance calculation and workshop layout design (CAD). The main results are as follows: design instruction, workshop layout plan.
Key Words: Bumper; dashboard; modified polypropylene (PP); injection molding; workshop layout
