Problems solved by technology

[0003] The front cover of the van is relatively small, and the production process is relatively simpler than that of ordinary cars, SUVs and other models. However, due to the importance of the front cover, the production process is not simple, and many car front covers now Some PVC materials are used, although the price is very low, but the safety performance is very poor

The main models are generally made in China, such as Jinbei, Zh...
