I remember that Meng Haoran, a famous poet in the Tang Dynasty, once wrote: "Chu people don't know each other, where can they ask for a chair." The chair-wu refers to the phoenix resting on the phoenix tree, and the chair represents rest. The image of the chair rest furniture is from the Hu bed. Many scenes in the Dunhuang frescoes reproduce the use of chairs and stools in the family of official nobles during the Northern and Southern Dynasties. It can be seen that chairs have a long history in our country. The plastic chairs made by the main material plastic chair injection mould on the market are generally made of PP or PE plastic.
Polypropylene, also known as PP, is a semi-crystalline thermoplastic. It has high impact resistance, strong mechanical properties, resistance to a variety of organic solvents, and acid and alkali corrosion. A plastic chair made of this material. Polypropylene is widely used in the production of clothing, blankets and other fiber products, medical equipment, automobiles, bicycles, parts, pipelines, chemical containers, etc. It is also used in food and pharmaceutical packaging.
Like chairs, most electrical appliances need molds to make them. However, as people's living standards are getting better and better, there are more and more types of electrical appliances, and there is also more and more electrical appliance mould .
