About the production technology of automobile injection mold
Apr 18, 2022
With the rapid development of the automobile industry and the trend of lightweight automobiles, the proportion of plastics in automobiles is increasing. The rapid development of the automobile industry has mobilized the development of the automobile injection mold industry.
There are many complete and huge automobile production bases in China, and the corresponding auto parts customer supply chain is also expanding. More and more manufacturers are interested in the processing and production of various auto parts. With the maturity of production technology, the production process is not Secret again. Under the influence of fierce competition in the market, more spirits of auto parts manufacturers have shifted from the client to the constraints of the production process, to meet the needs of customers with quality, and to produce high "quality" products.
1. Plastic can be processed at one time, with short processing time and guaranteed accuracy. Trials can hold a second shaping while the client allows it, and the junk takeover is very high.
2. The plastic product itself is relatively light, has good elastic deformation, can absorb a large amount of collision energy, has a much better buffering effect on strong blows than other materials, and can better protect the vehicle and occupants. The front part of the dashboard of a car is an easily deformed part.
Management skills: In the environment where the wall thickness is not increased, the reinforcing ribs usually increase the strength of the injection molded parts and improve the deformation of the injection molded parts. However, if the reinforcing rib design is not reasonable, the deformation of the injection molded part will increase.
3. Automobile injection molds have very strong corrosion resistance, and partial damage will not erode. It is almost very difficult to find non-plastic parts for automotive air conditioning cooling systems.
4. Add different additives, plasticizers, curing agents, and elastomers, and make modifiers to meet other applications and requirements of automobiles. What's more convenient is that the color of plastic can be adjusted with masterbatch and powder, which eliminates the difficulty of paint, and the electroplating performance of plastic is better than other materials.
Injection molding of automobiles is a major development trend of today's international automobile production industry, especially the interior and exterior decorations are mostly plastic. The plastic parts inside are mostly instrument panel accessories, seat accessories, floor accessories, roof accessories, steering wheel accessories, door inner accessories, rearview mirrors, various buckles and fixtures. Appearance car injection molds include front and rear lights, air intake grilles, fenders, mirrors, etc.
