However, due to the different existing truck models, the outer diameters of the tires are different. Different types of tires need to be matched with different types of fenders so that the arc-shaped fenders can cover the tires. The difference between different types of fenders is that the lengths of the connecting plates are different. However, an existing truck fender injection mold can only inject one type of fender, so it cannot be used for the injection molding of different types of fenders, and its applicability is poor.
