car parts mould plastic rubber, the difference between rubber and plastic products and rubber products?

The essential difference between plastic and rubber is that plastic deformation occurs when plastic deformation occurs, while rubber is elastically deformed. In other words, plastic is not easy to return to its original shape after deformation, while rubber is much easier. Plastic has little elasticity.

Most of the molding process of plastic has been completed, and the product process has also been completed; after the rubber molding process is completed, a vulcanization process is required.

Both plastics and rubber are polymer materials, mainly composed of carbon atoms and hydrogen atoms, and some also contain a small amount of oxygen, nitrogen, chlorine, silicon, fluorine, sulfur and other atoms. They have special properties and special uses. At room temperature, plastic is solid, very hard, and cannot be stretched out of shape. However, the rubber hardness is not high, it is elastic, it can be stretched and lengthened, and it can be restored to its original state when it stops stretching. This is because of their different molecular structures. Another difference is that plastic can be recycled multiple times, while rubber cannot be recycled directly. Only after processing can it be made into glue.

Rubber is actually a type of plastic. Plastics include rubber.

The tire rubber of the auto lamp mould factory will become hard and brittle in winter, and the friction coefficient will decrease, so the tire pressure should not be too high, but not too low. Low outside temperature, low tire pressure and severely soft tires can accelerate tire aging. In winter, the debris on the tread should be cleaned, avoid using tires that have been repaired many times, and replace tires with greater wear, different brands, and different patterns. Tires wear very differently inside and out. To reduce wear and tear, tires should be replaced regularly.
