Automobile Fender Liner Plastic Injection Mold

Automobile Fender Liner Plastic Injection Mold

it is a very big automobile fender liner plastic injection mold ,more than 1.5 meters with just one cavity. Asia Billion make the mold with in 10 weeks and mold are ready to shipped at 15 weeks. it is our first time to make the automobile fender liner plastic mold and we learn more fromour customer duering this project. we would like to cooperate with you too for any similar project.

Product Details

 Asia Billion Plastic Injection Tooling Quality Control

  The fender is the outer part that covers the wheels. Its function is to ensure the maximum limit space when the front wheels rotate and jump, and can reduce the drag coefficient too.The function of the inner lining of the fender cannot be ignored, it can effectively reduce the impact of road noise on the cockpit, prevent the damage to chassis which caused by the sand and stones that thrown out during the rolling of the tire, and reduce the drag coefficient of the chassis;


 At present, the automotive inner fender lining plates are made of plastic injection molding. The lining plates are easy to freeze on the road in winter, which seriously affect the normal driving feeling of the car, and the inner lining plates are also easily  been damaged because of frost cracking. When the tyre of the car is hit by some bigger object, the inner lining made of plastic is often shattered. In addition, the inner lining made of plastic will generate a lot of noise during driving, which is not conducive to normal driving.

 In the process of using the fender inner lining of the car, because it is close to the tire and the use environment is complicated, it often experiences wind, sun, freezing , impact and other factors, so it is easy to break, and it is a part that is relatively easy to damage in the car exterior. In the design of this project, we choose the HDPE material which still can work well under 40 degree of below zero. it is double the low temperature performance capacity than the normal pp plastic, our customers also have added special horizontal and vertical reinforcing ribs to increase the strength of the product to reduce damage risk. In addition, after the product is injection molded, a spraying process is generally used to spray asbestos and other materials on the side of the product near the tire and attach it to the fender to solve the above troubles.

  We can't be always an expert for any different project , but we always keep trustable , keep learning and asking if we don't know .After this project experience , Asia Billion can be a qualified automobile fender liner plastic injection mold and mudguard plastic injection mold maker for automotive industry, let us know freely if we can do something for you too.
