Automotive injection molding parts plastic requirements
Good weather resistance, ensure long time use no discoloration, no aging crack (including heat resistant oxygen aging and light aging);
Good chemical resistance to resist oil and daily chemicals;
Easy molding, injection grade materials should have enough liquidity, to ensure the formation of complex structural parts, and improve production efficiency;
Economy, the requirement material has high cost performance.
Material requirements for exterior trim
Weatherability: for parts not coated or electroplated, weather-resistant materials should be selected, such as AES, ASA (AAS), PC/PBT (PET), etc.;
Heat resistance: due to the low ambient temperature, the standard heat resistance level can meet the requirements;
Low temperature resistance: the material is required to have a certain low temperature resistance to prevent the cracking of components in low temperature environment in winter;
Chemical resistance: to prevent oil and acid rain erosion;
Scratch resistance: the material is required to have a certain surface hardness and low friction coefficient, in order to prevent scratches.
Material requirements for interior trim
Heat resistance: due to the long sunlight in summer, the temperature inside the carriage is relatively high, so the interior decoration materials are required to have high heat resistance.
Aging resistance: including thermal oxygen aging and light aging, prevent parts from aging and deterioration;
Odor: for the health of drivers, the materials should be low volatile and low odor.
Matte: matte material or matte skin texture is selected to ensure driving safety;
Scratch resistance: the material is required to have a certain surface hardness and low friction coefficient to prevent scratches.
