How is the production of plastic pellet extrusion equipment?

In daily life, we often encounter plastic products, such as rubber and plastic sealing strips, plastic tubes, plastic wires, plastic tubes and so on. These products are either in the extrusion molding process or in the casting process. No matter which molding process is used, most of the production process uses plastic pellets.

So how do plastic pellets come out? First of all, the raw materials of plastics should be adjusted according to the quality of the products. These raw materials include resin powder, oil, calcium powder, recycled plastics, etc. These raw materials are mixed by a kneading machine. The raw materials are thoroughly mixed under the high-speed high-temperature stirring of the kneading machine. When all the raw materials are uniformly mixed, the raw materials can be put into the plastic pellet machine for extrusion.

The plastic pellet machine is a plastic granulator that we often say, and it is a kind of plastic extruder equipment. The raw materials enter the screw barrel of the equipment through the feeding funnel of the plastic extruder to start heating up. As the temperature of the barrel increases, the plastic raw materials begin to plasticizer in the extruder barrel, and the extruder screw rotates to these. The plastic in the molten state is subjected to a series of processing such as shearing, kneading, compression, and exhaust.

Finally, a plurality of cylindrical strips is extruded at the die of the plastic pelletizer. After the strips are cooled by water, the shape is stabilized. We can cut these strip-shaped cylindrical products into ours by the tractor. The particles needed.

The quality of the plastic pellets has a direct relationship with the formulation of the product. At the time of production, we must formulate the formulation according to the quality of the product to be produced. In addition, when the granules are produced, the unsuitable products are usually crushed and then granulated, and the crusher is also indispensable in the plastic granule extrusion line.
