1. High hardness and wear resistance 9Cr18MoV is a high-carbon chromium stainless steel. After heat treatment, the hardness can reach HRC 58-62, which is suitable for making high-strength and high-wear-resistant tools and parts. In the design of conical twin screws and cylinders, high hardness and w... read more
1. Improve hardness and wear resistance The nitriding surface treatment technology can form a high-hardness nitriding layer on the surface of conical twin screws and cylinders, thereby improving the hardness of the screw. For example, the surface hardness of the screw barrel made of 38CrMoAlA high-q... read more
1. Exhaust capacity The core function of the exhaust screw is to remove gases and volatiles from the molten material. Its exhaust capacity directly determines the amount of residual gas and volatiles in the extruded product. Efficient exhaust capacity can significantly reduce defects such as bubbles... read more
1. Design features of exhaust screw Exhaust channel or notch: The exhaust screw is designed with special exhaust channels or notches, which allow gas to escape from the material during the rotation of the screw. Their position, number and shape are carefully designed to ensure that the gas can be di... read more
1. Automobile industry Body manufacturing: In the process of automobile manufacturing, high-speed screws are widely used to fasten various parts of the body, such as hoods, doors, etc., to ensure the overall structural stability and safety of the car. Engine assembly: In the assembly process of the ... read more
