The products of plastic pellet extruder are plastic raw materials, which can be processed by various processing methods into many objects of daily life, such as plastic bags, mugs, various boxes, stools, tables, toothbrushes, mice, telephones, headphones, hangers, washing machine shells, plastic doors and windows, wheels, slippers, Pen holder and so on.
What are the processing characteristics of plastic pellet extruders?
What is the production process of plastic pellet extruder?
How do I operate the plastic pellet extruder for the first time?
The extrusion process of the plastic pellet extruder generally refers to the melting of the plastic at a high temperature of about 200°C, and the molten plastic forms the required shape when passing the mold. Extrusion molding requires a deep understanding of plastic properties and rich experience in mold making. It is a molding process with high technical requirements.
The plastic pellet extruder is a process in which the material is continuously passed through the nozzle by heating and applying pressure in the extruder in a flowing state. Compared to other molding processes, it has the advantages of high efficiency and low unit cost.
The plastic pellet extruder is a kind of plastic extruder that needs to be heated before production, and then the plant is started for production. As a rule, in the production of plastic granules, it is equipped with a hot cutting head or granulation. The plastic granulate extruder is extruded into a series of round rods and then cooled and cut by the pelletizer into the plastic pellets we need. This completes the production of transparent plastic granules. The transparent plastic granulate machine needs a special machine and cannot be mixed with other color granulate machines to ensure the quality of the product.
1.Before starting the plastic granulate extruder, heat it up for about 40 to 50 minutes. Increase the temperature so that you can manually pull the motor V-belt until it is free; Pull it eight to ten times continuously according to the normal working direction. Then continue to heat up for about ten minutes and then turn on the machine, but continue to heat up as normal production must continue to supplement heat. Set different temperatures according to the different properties of plastics.
2.If the plastic pellet extruder works normally, the temperature of the machine should be kept stable and not fluctuate. Near the air outlet, the temperature of the machine top should be kept at about 200 °C (relative to material C and B).
3.Feed the plastic pellet extruder evenly and add enough. The feed speed of the machine and the feed speed should be precisely matched. Otherwise, the quality and yield of the pellets will be impaired.
4.When the plastic granulate extruder is shut down, the host must completely cut off the power supply. The locking screw of the machine head (the part with the key) must be removed. Preheat separately before next use.
