Auto parts can be divided into five categories: starting system, driving system, body accessories, steering system and braking system. There are many kinds of auto parts. A car is a highly safe product. Especially in the event of an accident or collision, the combustion performance of the internal materials is crucial to the safety of passengers. The flame-retardant plastic used in auto parts can prevent the spread and combustion of fire to a certain extent, and reduce the threat of fire to passengers after an accident. Injection molding devices are needed in the production process of auto parts. The flame-retardant plastic is loaded into the heating box from the feed funnel. The flame-retardant plastic is heated by the heating box to form a molten fluid. The fluid is stirred and transported to the injection head by a screw. The molten material is injected from the injection head into the mold cavity of the mold. After cooling, various shapes of auto plastic parts are made. After the mold is opened, the auto plastic parts in the mold cavity are taken out by manipulators, suction cups, etc.
