How does the plastic extrusion equipment work?

We know that plastic extruders play an important role in the production of actual plastic products. For example, many products such as sealing strips, plastic tubes, plastic sheets, etc. are extruded by plastic extruders, so plastic extruders are widely used in the production of plastic products. So how does the plastic extruder work? Before production, we first need to heat the plastic extruder barrel, and when the temperature rises to the temperature we need, we can process the plastic that has been refined and opened.

The plastic enters the barrel through the feeding system of the extruder and then is cut, compressed, kneaded and the like by a plastic extruder screw. Finally, it is extruded at the die of the plastic extruder into the shape of the product we need.

During the whole production process, the screw of the plastic extruder is continuously running, and the screw barrel, the plastic, and the screw continuously interact to produce the self-production temperature. Then the temperature of the plastic extruder barrel will gradually increase with the continuous production of the equipment, but the plastic will produce vulcanization in the production of excessive temperature and even cause the plastic to produce scorch, so when we are in production It is necessary to set the temperature control part of the plastic extruder to a maximum temperature. When the temperature of the barrel of the plastic extruder reaches the temperature we set, the temperature control system will automatically deliver cold water to the screw extruder of the plastic extruder. Cooldown. Throughout the production process, the temperature control system and the screw are continuously exchanged information to maintain stable production of the equipment.

When we produce different types of plastics or products, we need to adjust and control the temperature of the equipment according to the specific conditions. The temperature requirements of the equipment are not static. We need to adjust to the actual situation.
