With the continuous changes and development of the technological era, cars have gradually been used in our lives, and they are also widely used. It is understood that the current automobile industry is very popular with the public in today's era, and the total annual sales volume is getting higher year by year. Everyone must know a lot about cars, but I believe that everyone doesn’t know much about the various parts and molds of cars. For example, car lights are a general term for all automotive lighting systems. Car lights have very high requirements for appearance, so they have extremely high requirements for mold design and manufacturing. The headlight uses H7 as the high and low beam light source, which switches between high and low beams through a motor and a baffle. The position light uses 8 LEDs and has a separate position light mirror. Many people are not very clear about the requirements for the appearance of plastic parts. So what is the appearance of plastic parts? Next, let Xiehe manufacturer give you a brief introduction.

1. Under certain circumstances, based on the characteristics of the plastic parts, we can know to a certain extent that the lamp housing plastic parts have the risk of mold sticking, and the design of the plastic parts needs to prevent mold sticking. Generally, plastic parts are internal functional parts, lamp holder holes, back cover holes and other assemblies, and the requirements for these assemblies are very high.

2. Among plastic parts materials, non-appearance parts are a relatively special material. The requirements in all aspects are that they must meet its main standards. Otherwise, the products produced will not meet the standards. Generally, the appearance of plastic parts is not allowed. There are spots, shrinkage dents, weld marks, flash and other defects. The requirements for appearance shrinkage are not very high, and can be matched at will in all aspects.

3. The appearance of plastic parts is actually relatively complex. Common plastic parts have 6 undercuts on the outside and require a lateral core-pulling structure. Except for the fact that the lamp hole is not a left-right mirror image, all other features of the lamp housing are left-right mirror images.

In summary, the above is the editor’s preliminary understanding of this product. If you want to know more, please feel free to call our Xiehe manufacturer.
