Description

Injection molding is a method of producing shapes for industrial products. Products are usually injection molded from rubber and plastic. Injection molding can also be divided into injection molding and die casting. Injection molding machine (referred to as injection machine or injection molding machine) is the main molding equipment for making thermoplastic or thermosetting materials into plastic products of various shapes by using plastic molding die. Injection molding is realized by injection molding machine and mold. Rubber Injection Molding: Rubber injection molding is a production method that injects rubber directly into the mold from the barrel. The advantage of rubber injection molding is that although it is intermittent operation, the molding cycle is short, the production efficiency is high, the blank preparation step is eliminated, the labor intensity is small, and the product quality is excellent. Plastic injection molding: Plastic injection molding is a method of plastic products. The molten plastic is injected into the plastic product mold by pressure, and the various plastic parts are desired by cooling molding. There are mechanical injection molding machines dedicated to injection molding. The most commonly used plastic at present is polystyrene. The resulting shape is often the final product and no further processing is required prior to installation or use as a final product. Many details, such as bosses, ribs, threads, can be formed in one injection molding operation. Injection molding is a common way of using plastic materials. However, precision injection molding is the pursuit of high-precision injection molding products. Precision injection molding has two indicators: one is the precision of the equipment, and the other is the mold error precision injection molding has the most excellent injection-related products. The injection molding process is the process of shifting the bumper plastic from solid (powder or pellet) to liquid (melt) to solid (product). From the pellet to the melt, and then from the melt to the product, the temperature field, the stress field, the flow field and the density field are used in the middle. Under the action of these fields, different plastics have different polymer structures. And rheological properties.

In the process of injection molding of automobile bumper, it is necessary to use the molding die material, the existing material does not have a buffering effect, and the structure is not strong, and the flame retarding effect is not good.
