How to Improve the Service Life of Screw Barrel

1. Selection of high-quality materials: The materials for the screw barrel should be high strength, high wear resistance, and high corrosion resistance materials, such as high-quality alloy steel, stainless steel, etc. 2.Strengthening surface hardening treatment: Through surface hardening treatment, the hardness and wear resistance of the screw barrel can be improved. Common surface hardening treatment methods include nitriding, hard alloy coating, etc. 3.Strengthen lubrication maintenance: The screw barrel needs to be kept in a good lubrication sta

Uses and differences of different types of screw barrel

The screw barrel is one of the core components of a plastic extruder. Its function is to melt and compress plastic, pushing it through the extrusion port to form the desired product. Different models of screw barrel are suitable for different extrusion processes and plastic materials, with the main differences in the following aspects: Diameter and length: The diameter and length of the screw barrel can affect the melting and extrusion effects of plastics. Generally speaking, the larger the diameter, it is

What is the cause of the slippage of the injection screw

For hygroscopic materials (such as nylon), the high water content of the resin can also cause the screw to slip. Improper drying will significantly reduce the viscosity of the material and generate water vapor in the drum, resulting in a reduction in the conveying capacity of the screw. In fact, there are many reasons for slippage, which may be related to high back pressure, overheating or overcooling of the end of the cylinder, wear of the cylinder or screw, conical screw b

What is the difference between screw and lead screw

The screw consists of a feeding section, a compression section and a metering section. The outer surface of the screw is a cylinder with a spiral groove or a cone with a conical spiral groove. Screws are used in plastic molding equipment, barrel nuts and screw such as plastic profile extruders, injection molding machines, molding machines, rubber machines, etc. Screw and barrel are the core components o

What causes the injection screw to slip

I think most users will be troubled by this problem, that is, the injection screw is slipping. So what caused this situation? For hygroscopic materials (such as nylon), the high water content of the resin can also cause the screw to slip.
