Production capacity of plastic extrusion equipment

The relationship between the production capacity of plastic extrusion equipment and the screw speed is that as the screw speed increases, the production capacity increases. However, if the screw speed of the plastic extruder is too high, the production capacity is limited, and the rubber material is prone to burning; The relationship between the power of a plastic extruder and the screw speed is that as the screw speed increases, the power also increases, but as the screw speed of the plastic extruder increases, the power gradually decreases. The relationship between the head pressure of a plastic extruder and the screw speed is that as the screw speed increases, the head pressure also increases. Rubber material and cylinder: The relationship between rotational speed and the shearing, kneading, plasticizing, and heating of rubber material inside the cylinder.

The inner surface hardness of the plastic extruder barrel is higher than that of the plastic extruder screw, and the damage occurs later than that of the plastic extruder screw. The scrapping of plastic extruder barrel is due to the wear and tear of time, which increases the inner diameter. If the plastic extruder barrel has a nitriding layer, the inner hole of the plastic extruder can be directly drilled, ground into a new diameter size, and then a new extruder screw can be prepared based on this diameter.

Mechanically process the inner diameter of the plastic extruder cylinder, then cast an alloy with a thickness between 1-2mm, and refine it to size. In general, the homogeneous section of a plastic extruder barrel wears out quickly and can be bored and trimmed with a nitrogen impregnated alloy steel liner. The diameter of the inner hole of the plastic extruder barrel refers to the diameter of the screw of the extruder, and the plastic extruder barrel and screw can be left in a normal gap suitable for processing and machining.
