Production process of plastic granulator

Feb 20, 2020Leave a message

Plastic granulator is also called plastic pellet extruder. It is a kind of plastic extruder. Most of the plastic products common in our daily life are produced from plastic pellets. For example, plastic sealing strips, plastic tubes, and plastic barrels must be extruded with pellets before production to complete subsequent product molding. 

So how are plastic particles produced? We know that different products have different requirements for raw materials. When we produce plastic granules, we must first formulate the raw material according to the quality of the product. We mix various raw materials together with a kneader according to the formula of the product. well mixed. After all the raw materials are mixed well, they can be put into the feeding system of the plastic granulator for feeding. 

The raw material enters the screw barrel through the funnel-shaped feeder of the plastic pellet machine and is plasticized by heat, and is continuously extruded forward with the rotation of the screw. The screw thread shears, compresses, and mixes the raw material. After processing, the exhaust gas in the raw materials will be discharged from the exhaust port, and give the raw materials a forward thrust. The raw materials are continuously pushed forward by the processing of the screw and finally extruded at the die of the plastic extruder and extruded the screw barrel to form the shape we need. Generally, the granulator extrudes many cylindrical shapes. These strips are cooled by water and then pelletized by a pelletizer to complete the production of pellets. There are many production processes of plastic pellets. Sometimes we need to equip the plastic extruder die with a hot-cut die and cut the product into the plastic pellets we need at the same time.
