Application of Nylon on the Cover of the Air-valve Chamber
2023-11-20
The valve chamber cover is used to protect the cam cover, at the same time it can prevent oil leakage and reduce noise. The parts have traditionally been molded from aluminum or thermosetting plastic, but glass or mineral-reinforced nylon is becoming an ideal choice in this area.
Nylon's excellent rigidity, mechanical strength and outstanding thermal aging performance at high temperatures can meet the demanding application requirements of engine compartment components. At the same time, due to the harmonious collocation of glass fiber and mineral powder, it has low shrinkage and isotropy, so the warping deformation is small. In addition, since the modified material has a relatively low thermal expansion when the temperature rises (the molded part has little creep after passing the high temperature test of 5000h), oil leakage can be avoided. Furthermore, more complex oil vapor separation systems can be integrated through welding to reduce fuel consumption and meet increasingly stringent emission standards.
