How to select high-quality screws and barrels for plastic extruders

In this era of rapid development of the plastics industry, the application of plastic extruders is becoming more and more widely valued and known. The screw and barrel used in the plastic extruder is one of the core parts of the equipment, which has an important influence on the plasticization, kneading and molding of plastics. Therefore, the reasonable selection of screw structure and parameters is one of the prerequisites for improving product quality and output value. High-quality parts can better ensure normal production and improve key data such as yield and output. To meet the needs of different plastic processing. There are many kinds of screw structures, and there are three common types: gradient type (equal depth unequal distance or equal distance or unequal depth unequal distance), sudden change type, torpedo head type, etc.

How to ensure the stability and rheological characteristics of the extrudate in the design and manufacture of rubber screw cylinders

In the design and manufacture of rubber extrusion screw barrel, the stability of the extrudate should be considered, which mainly includes two aspects: one is the flow stability of the extrudate in the barrel, and the other is the shape and size of the final extrusion. Stability.

Attention should be paid to the shutdown of the twin-screw extruder.

Gradually reduce the screw speed of the main engine, and exhaust the residual material in the cylinder at low speed. (For heat-sensitive materials that are easily decomposed by heat, polyolefin materials shall be used to clean the main engine before parking.) After the materials are basically discharged, adjust the screw speed to zero, press the main motor stop button, and at the same time close the valve beside the vacuum chamber and open the vacuum chamber cover.
