Automotive bumper injection molding parts mainly include engine parts, water tank parts, air conditioner parts, air filter parts, various instrument panel parts, seat parts, floor parts, roof parts, gear lever parts, steering wheel parts, door interior parts, rearview mirrors As well as various buckles and fixings, front and rear lights, air intake grilles, fenders, rear mirrors, etc.
In the automobile injection molding parts, the corresponding plastic welding technology is mainly used. In the automobile industry, welding is a key link in the manufacture of automobile parts and bodywork, and plays a special role in connecting the previous and the next. Complexity, specialization and standardization of parts production, as well as the comprehensive requirements of automobile manufacturing in terms of quality, efficiency, and cost, all determine that automobile welding is a multi-disciplinary, cross-field and technically integrated production process.

There are two types of plastics for automobile injection molding parts: one is thermosetting plastic, which can withstand ordinary baking operations; the other is thermoplastic, which has the advantages of easy and fast processing. Among automotive plastics, the top 7 plastic materials and their proportions are roughly as follows: polypropylene 21%, polyurethane 19.6%, polyvinyl chloride 12.2%, thermosetting composite material 10.4%, ABS 8%, nylon 7.8%, Polyethylene 6%. The commonly used plastic welding techniques are: ultrasonic welding, hot melt hot plate welding, vibration friction welding and laser welding. Nicol's main automotive ultrasonic welding equipment and automotive hot-melt hot plate welding equipment are commonly used in: car lights, car dashboards, car fuel tanks, car expansion kettles, car bumpers, car dashboards, car battery shells, etc.
When it comes to the advantages of automotive injection molding parts: automotive lightweight has become a common hot spot between the plastics industry and the automotive industry. Plastics cater to automotive lightweighting is the general trend. Driven by the concept of energy saving, safety, comfort, light weight, and energy saving have become the main trends in the future development of the automotive industry. Plastic has become a good material choice for the automobile industry in the 21st century due to its advantages of light weight, large design space, low manufacturing cost, excellent performance, and wide range of functions. The application of plastics in automobiles actually has more advantages.
In addition to reducing the weight of plastic instead of metal, it can also reduce the friction between automobile transmission parts, especially the surface friction with metal (aluminum, copper), which not only reduces the friction coefficient, but also improves the sealing performance and achieves better wear resistance. Sex. Improve design flexibility and component integration, improve safety, comfort and fuel efficiency, and achieve better sealing and noise isolation effects. The overall outlook for China’s economy is positive. The rapid development of urbanization will inevitably drive greater demand for transportation. The focus of the future auto market will be to improve fuel efficiency and promote the development of hybrid vehicles and even electric vehicles. Plastics Will usher in broader development opportunities.
