Products Description
In automobile engines, plastic parts are widely used. First of all, our Car Engine Plastic parts is the valve cover of the engine. The valve cover has the advantages of weight reduction, vibration reduction and noise reduction, low cost and can meet complex structural design.
The valve cover of the Car Engine Plastic parts' main functions are
1. The function of sound insulation The plastic cover of the engine compartment has the function of sound insulation , which can greatly reduce the impact of engine noise and improve driving comfort.
2. The function of heat preservation The engine compartment cover has a certain heat preservation effect on the engine, which can shorten the time for starting the hot car from cold, reduce fuel consumption, and reduce engine carbon deposition caused by idling.
3. Dustproof function At the same time, with the plastic cover of the engine compartment, it can block the dust for the engine, so that the engine is clean and free from the harm of dust.
Car Engine Plastic parts mainly include
PUR material:
Fuel pipe protection cover, high pressure fuel rail protection cover, high pressure fuel pump protection cover, high pressure fuel pump frame cover. These parts are used to protect the components while eliminating noise, and the foamed plastic is used because the material retains its shape when molded, is softer, and costs less.
PA66 (with PA66-GF reinforcement):
Oil dipstick, intake manifold, cylinder head cover, oil pan wire harness bracket, chain tensioner arm, engine carbon canister solenoid valve muffler, etc. This material is mainly used because PA66 has higher fatigue strength and rigidity, and its blended modified material has higher wear resistance and better heat resistance.
PA46 (with PA46-GF reinforcement):
It is mainly used for some parts of the throttle valve. This material has excellent heat and wear resistance, but due to its high cost, it is generally used less.
PA6:
Used in oil filter, it has the advantages of high strength and wear resistance, and has good durability and mechanical properties after glass fiber reinforcement.
PPA:
It is used for engine water jacket. Since the water jacket has been in high temperature and high humidity for a long time, PPA is used. It has high tensile strength, strong heat resistance and strong coolant resistance under high temperature and high humidity. this material.
PBT:
It is mainly used for some parts of the ignition coil, because the material has excellent electrical properties and flame retardant ability, and at the same time, the heat-resistant aging temperature is high, which can meet the working conditions of the ignition coil.
PPS:
It is mainly used for some parts of ignition coils. The main advantages are that the water absorption rate is extremely low, the flame retardancy is good, the heat resistance and electrical properties are good, and the creep resistance under load is strong.
