What are the molding methods for recycled plastics?

PP PE flake products recycling and pelletizing machine

Plastic is a polymer material with resin as its main component.

The molding machine of plastic granulator is very important in the plastic processing process.

It has plasticity at a certain temperature and pressure, and after molding, it can maintain the shape and size and meet certain performance. Because plastic has the lightweight, high specific strength, excellent electrical performance, superior chemical stability, small friction coefficient, excellent wear resistance, good shock absorption and noise reduction, good elasticity, easy forming, easy cutting, and easy welding. It has good characteristics of bonding with metal, glass, wood and other materials. In addition, it is rich in raw materials, so it has been widely used in people’s life, industrial and agricultural production, and the national defense industry.

After a long period of struggle and openness to the world, China’s plastics industry has also formed a relatively complete industrial system. From the perspective of synthetic resin, plastic granulator, and plastic products, it shows the strong development momentum of China’s plastics industry. Plastic molding methods can be divided into film pressing, laminating, injection, extrusion, blow molding, casting plastics and reaction injection plastics. Among them, extrusion molding plays an important role in the plastic molding processing industry. In the molding process of plastic products, the output of extruded products has always ranked first in plastic products. Although some extruders can be molded directly from powdered materials, most plastic machines still require the use of initially plasticized pellets for forming.

Plastic granulators are commonly used in the processing of waste plastic film (industrial packaging film, greenhouse film, beer bags, handbags, etc.), woven bags, agricultural convenience bags, basins, barrels, beverage bottles, furniture, daily necessities, etc., especially suitable for large Recycling of some common waste plastics. With the rapid development of the granulator industry, beverage and beer matching granulators will have greater development potential.
