Automotive Plastic Part Application And Welding

　　100kg of plastic material on modern cars has replaced the traditional metal material that originally required 200-300kg, and the weight reduction effect is very prominent, which is of great significance for saving energy and reducing greenhouse gas emissions. According to statistics, there are dozens of types of plastics used in automobiles, and the average amount of plastics used in each automobile accounts for 5% to 10% of the car's weight. The use of bicycles will further increase in the future. This is also in line with the trend of the contemporary low-carbon economy!

　　In modern vehicles, whether it is exterior trim parts (such as bumpers, fenders, wheel covers, air deflectors, etc.), interior trim parts (such as instrument panels, door inner panels, sub-dashboards, glove box covers, seats, etc.) Chairs, rear guards, etc.), or functional and structural parts (fuel tank, radiator water chamber, air filter cover, fan blades, etc.), the shadow of plastic parts can be seen everywhere.

　　Automotive plastic part welding technology:

　　The use of automotive plastic parts in automobiles requires corresponding plastic welding technology. In the automobile industry, welding is a key link in the manufacture of auto parts and bodywork and plays a special role in connecting the previous and the next. The specialization and standardization of parts production and the comprehensive requirements of automobile manufacturing in terms of quality, efficiency, and cost all determine that automobile welding processing is a multi-disciplinary, cross-disciplinary, and technically integrated production process.

　　There are two types of plastics used in automobiles: thermosetting plastics, which can withstand ordinary paint baking operations, and thermoplastics, which have the advantage of being easy and fast to process. In automotive plastics, the top 7 plastic material varieties and proportions are roughly: polypropylene 21%, polyurethane 19.6%, polyvinyl chloride 12.2%, thermosetting composite materials 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. Niko specializes in automotive ultrasonic welding equipment and automotive hot-melt hot plate welding equipment, which are commonly used in automotive lamps, automotive LCD instrument plastic parts, automotive fuel tanks, automotive expansion kettles, automotive bumpers, automotive dashboards, automotive battery shells, etc.
