The difference between plastic granulators and plastic extruders

The appearance of plastic granulators and plastic extruders is generally the same, but the production processes are not quite the same. The basic molding production process of a general extruder is that after the particles enter the feed port of the plastic extruder, the screw is used to plasticize the particles, squeeze the raw material to the head of the extruder for molding, and then cool to obtain the product we need.

Difference Between Plastic Granulators and Plastic Extruders

The production process of plastic granulation is that the feed port is to be fed with powder. After the powder is plasticized, it is cut into particles by the head or extruded into a long strip by the extruder, and then cut into particles by the cutting machine.

Plastic extruders are mainly suitable for the processing of plastics such as PVC, PE, PP, ABS, and TPE. With various auxiliary equipment, it can directly make plastic products such as profiles, sheets, and pipes by plasticizing and extruding.

Plastic granulators are mainly suitable for the granulation of PP, PE, PS, PET, ABS, PC, and acrylic sheets or granular materials. Processing of original packaging materials and recycled materials.

The difference between plastic granulators and plastic crushers

A plastic crusher, also known as a plastic shredder, is used to break plastic products into irregular particles smaller than one centimeter.

A plastic granulator is a machine that re-forms plastic particles into green bean-sized plastic particles by melting, plasticizing, compressing, and extruding the crushed plastic particles into a plastic extruder.
