Due to the Superior performance of plastics, a large amount of plastics are used in automobile exterior parts and interior design, which can not only achieve design performance requirements such as lightweight automobile structures, safety, anti-corrosion, styling and comfort, but also help reduce costs and save energy. The applications of our plastic parts in automobile interior and exterior applications include bumpers, seats, lights, reflectors, center armrests, folding tables, door panels, etc. We have an injection molding workshop, and the largest injection molding machine is 3,000 tons which can produce various large plastic parts for automobiles. Because our injection molding workshop only has injection molding machines, all of our mass-produced automotive plastic parts use the injection molding process.
Our plastic parts for bumpers, seats, lights, center armrests, and folding tables are designed to be developed in aspects such as automotive aesthetics, coordination of overall decoration, reduction of drag coefficient, and improvement of driving maneuverability. After years of experience in injection molded manufacturing, our technology is becoming more and more mature. Our bumpers are generally made of modified polypropylene resin material; our transparent covers for car lights are made of highly transparent optical material PMMA; our car rearview mirrors are made of modified plastic PEEK with carbon fiber added to increase the hardness and toughness of the shell; others ABS materials are usually used in car seats, folding tables, door inner panels, etc. Our injection molding machine uses a heated barrel to melt the resin, and then pushes the molten resin into the mold. After the resin cools in the mold, the mold is opened and the product is taken out.
Our plastic parts of interior and exterior parts are mainly for modification and not supplied to automobile manufacturers. There is no need for the mold design to meet the high-tempo production requirements, so that the mold has sufficient cooling time to improve product quality. This can not only reduce mold costs, but also reduce product costs and increase the market competitiveness of our products. The molding cycle of products produced by our injection molding machines is generally more than 60 seconds. We design the mold with full consideration of two points. First, the structure cannot be too complex. During the process of opening and closing the mold, the movements are simple and compact. Second, the cooling effect of the mold is good, the mold material has excellent thermal conductivity, and the mold must be easy to arrange water channels.
