What Is an Extruding Machine?

An extruding machine，also known as an extruder， is a plastic processing machine, . It is a device that melts and extrudes plastic raw materials into shape through heating and pressure. The extruder usually consists of a hopper, a heater, a screw, and a cross head.

Plastic raw materials enter the extruder from the hopper and become molten after being heated by a heater. Then, the screw pushes the molten plastic forward and extrudes it into shape through the die head. The extruder can produce plastic products of various shapes and sizes, such as pipes, sheets, films, wires and cables, etc.

Extruder is one of the most important equipments in the plastic processing industry, widely used in the production and processing of plastic products.
