Custom Injection Automobile Wiper Mould
The windshield wiper is an important accessory installed on the windshield. Its function is to sweep away the rain, snow and dust on the windshield that obstructs the view. Therefore, it plays an important role in driving safety.
The key to a good wiper blade is that the rubber wiper strip can maintain sufficient moisture. Only with sufficient moisture can it have very good toughness to maintain close contact with the car window glass.
In the market, injection molded wipers are widely used in the manufacture of automobile wipers due to their excellent electrical insulation, fatigue resistance, and high toughness and fatigue resistance.

The plastic sheet on the wiper blade refers to a layer of plastic sheet covering the rubber sheet of the wiper, also known as the wiper skeleton, which is used to protect the rubber blade and ensure its life and performance. Common plastic sheet materials include polyethylene, polyurethane, polypropylene, polystyrene, etc.
The plastic sheet made of polyurethane has a certain elasticity and hardness, and its durability and scratch resistance are better than other plastic products. Because its polymer contains urea structure, it has excellent weather resistance and UV resistance, high temperature resistance and low temperature resistance, and is difficult to burr, so it is widely used in the manufacture of wiper blades.

The plastic sheet made of polyethylene material has good softness and ductility, light weight, but its UV resistance and cold resistance are poor, and it is easy to age. The plastic sheet made of polypropylene material has good rigidity and toughness, and has good shockproof performance, but its ability to resist severe sunlight is also relatively weak. The plastic sheet made of polystyrene material has good transparency and glossiness, but low hardness and poor durability.
