Automotive plastic mould parts molds are divided into three categories: interior parts, exterior parts and functional parts.

General requirements for plastic materials for automobiles:

  1. The impact strength and modulus are balanced (both with strong and tough properties, excellent dimensional stability, that is, the creep resistance of the material under long-term surface load is better);
  2. Good temperature resistance, ensuring that the material does not deform under illumination and heat;
  3. Specific surface properties such as matt, high hardness, scratch resistance, easy coating, plating, etc.
  4. Excellent weather resistance, ensuring long-term use without discoloration, no aging cracks (including heat-resistant oxygen aging and photoaging);
  5. Good chemical resistance to resist the erosion of oil and daily chemicals;
  6. Easy to molding, it should have sufficient fluidity for injection molding and materials, ensure the formation of complex structural parts and increase productivity.

Automotive plastic moulds for interior materials:

Heat resistance: due to the constant sunlight in summer, the temperature inside the compartment is relatively high, and the interior parts are required to have high heat resistance.

Aging resistance: including thermal oxygen aging and photoaging to prevent discoloration and deterioration of components

Odor: In order to maintain the health of the passengers, the material should ensure low volatility and low odor.

Matte: To ensure safe driving, choose matte material for matte finish
