CN-moulding is a mould maker and plastic injection molding factory in shanghai china, specializing in high-quality custom injection mold and plastic injection molding products –company,manufacturer,suppliers.

 
With the direction of the development of the lightweight car, the amount of plastic in the car is increasing, especially in automotive interior parts of the material increases the higher requirements. The use of lightweight plastic, rust-proof, vibration absorption, design flexibility features, modern automotive plastics structural parts made considerable development, and is one of the focus of the future direction of development.
Characteristics of plastics
The plastic is a synthetic resin (polymeric resin or a condensation resin) as a main component, and the mixture is added according to the different needs of the different additives consisting of, has unique properties:
• density: 100Kg per plastic can substitute other materials 200 ~ 300Kg, can reduce vehicle weight and increase payload.
• good physical properties: good flexibility, wear-resistant, shock absorbers, plastic unit mass impact resistance not inferior metals, some plastics, carbon fiber reinforced plastics, etc. are also much higher than the metal.
• Chemical resistance: Plastic acid, alkali, salt and other chemicals are resistant to corrosion, which is the most stable chemical properties of PTFE material; most commonly used corrosion-resistant materials, hard PVC, it concentration of 90% can be resistant to concentrated sulfuric acid, hydrochloric acid and various concentrations of lye.
• design flexibility: can be made transparent, translucent or opaque products, the appearance of a variety of surfaces can produce a distinctive pattern.

Plastic products can not only reduce the number of parts, reducing noise has also played a good role in automotive design and many conditions, in order to reduce weight and cost, greater use of plastic has important significance. Future trends in automotive materials transition from metal to plastic.
