Automobile injection spraying is one of the important technologies for automobile interior decoration. The popular explanation is to wrap a soft decorative layer on the surface of plastic products to beautify the appearance of plastic products while giving them a soft, delicate touch and visual pleasure similar to leather.
The Slush process was born in Germany in 1924. It was originally used as toy crafts. It was not until the 1960s that Japan used this process to create soft instrument panels and car door shells. In the late 1980s, Europe began to be introduced and quickly promoted. It was only introduced at the beginning of the 21st century, initially only in a few joint ventures. In application, it has not been gradually applied in domestic independent brands until recent years.
From its birth to the present, the level and precision of mold and molding control have been greatly improved. The precision and quality control requirements of the plastic molding process used in automobiles are not comparable with ordinary toys. It is not a technology that can be used well. However, the basic raw material of plastic is still paste PVC. The outer material of ordinary wires that are in daily contact is PVC.
Generally speaking, plasticizers are similar to adding vegetable oil to flour. It is easy to add oil, soft and resistant to nails. Both the composition of the PVC material and the precipitation of a large amount of plasticizer lead to the poor environmental friendliness of the material. With the increasingly stringent regulations on automobile environmental protection and safety, consumers have gradually improved their awareness of the air quality in the car, and PVC materials have been adopted by other more environmentally friendly materials. Replacement is a big trend.
