Plastic extruder machines are used to manufacture a wide range of consumer, industrial and agricultural products. But, no matter what the end use, the basics of the different plastic extrusion machinery remain the same.
The Extrusion Process
All plastic extrusion equipment is made up of a hopper, a barrel and a die. To break the process down, plastic resin is first fed into the hopper. Depending on the application, the resin may have previously been mixed with additives like UV inhibitors or colorants.
