Alloy Screw and Barrel manufacturers take you to understand the impact of excessive assembly clearance of the screw in the barrel
If the assembly clearance of the screw in the barrel is too large, what will be the impact? Presumably many people don't know it very well. The following Alloy Screw and Barrel manufacturers will take you to a brief introduction.
1. If the working surface gap between the screw and the barrel is too large, the amount of reflux material generated when the screw plasticizes and pushes the molten material forward is large. The manufacturer of Alloy Screw and Barrel tells you that the result is that part of the molten material stays in the barrel for a long time. Long and yellowish, resulting in discoloration or focal spots on the surface of the product.
2.Alloy Screw and Barrel manufacturers tell you that the output of the products produced by the extruder is unstable or the output is declining.
3. If the gap is too large, the pressure of the extruded melt will be unstable, resulting in a large error in the geometry and size of the cross-section of the product.
4. The manufacturer of Alloy Screw and Barrel tells you that because the gap is too large, the flow rate of the molten material pushed out by the screw barrel of the extruder is also unstable, which makes the surface of the product prone to transverse wrinkles.
