Plastic Extrusion Machines are essential equipment in the plastics industry, used to transform raw polymer materials into uniform pellets or finished profiles. They are widely applied in industries such as packaging, automotive, construction, and electronics. Understanding how they work helps B2B buyers choose the right solution for their production needs.
Feeding
Raw plastic materials, usually in the form of granules or powder, are fed into the hopper.
Melting
The material is conveyed by the screw into a heated barrel, where it gradually melts under temperature and shear force.
Mixing and Homogenizing
The screw action ensures that additives, colorants, or fillers are evenly dispersed in the molten plastic.
Extrusion
The molten plastic is forced through a die to form the desired shape or pushed into a pelletizer for granulation.
Cooling and Cutting
The extruded plastic is cooled using air or water, then cut into pellets or shaped into continuous profiles.

Plastic extrusion machines work by feeding, melting, mixing, extruding, and cooling polymers into usable forms. Choosing between a single screw machine and a twin screw machine depends on material type and production complexity. With advanced technology, strong R&D, and decades of manufacturing experience, HONGQI provide efficient, customizable extrusion solutions that meet the needs of global B2B clients.
