Four Commonly Used Plastic Processes Introduction

Plastic is a kind of material widely used in manufacturing, its strong plasticity, light weight, low cost and other characteristics, so that it has a wide range of applications in various fields. In the manufacturing process of plastics, there are also a variety of different processes, which will be introduced according to the categories below.

Injection molding is a common plastic processing process, which is formed by heating and melting plastic particles and injecting them into a mold. This process can produce plastic products of various shapes, such as plastic cups, plastic boxes, plastic parts and so on. The advantages of injection molding are high production efficiency, low cost and high product accuracy.

Second, Extrusion Molding

Extrusion molding is a process in which plastic particles are heated and melted and the molten plastic is extruded by an extruder. This process can produce various shapes of plastic pipes, plastic sheets, industrial plastic films, etc. The advantages of extrusion molding are high production efficiency, low cost and smooth surface of products.

Blow molding is a process in which plastic particles are heated and melted, and the molten plastic is blown into hollow products by a blow molding machine. This process can produce various shapes of plastic bottles, plastic buckets, etc. The advantages of blow molding are high production efficiency, low cost and lightweight products.

Calendering is a process in which plastic particles are heated and melted, and the molten plastic is calendered by a calendering machine. This process can produce various shapes of plastic film, plastic sheet and so on. The advantages of calendering are high production efficiency, low cost and smooth surface of the product.
