The injection molding screw is one of the key components in the injection molding machine. Its main function is to heat and extrude the plastic raw materials so that they are evenly melted and injected into the mold. The working principle of the injection molding screw can be divided into the follow... read more
1. Effect on wear resistance Improve hardness: Nitriding treatment forms a high-hardness nitride layer by allowing nitrogen atoms to penetrate into the surface of high-speed screws. This nitride layer can significantly increase the hardness of the screw, thereby enhancing its ability to resist wear.... read more
AISI 4140 alloy steel has a high carbon content (usually between 0.40% and 0.55%) and contains appropriate amounts of chromium and molybdenum elements, which give it extremely high strength and toughness. This makes AISI 4140 alloy steel exhibit excellent fracture resistance when subjected to impact... read more
1. High strength and wear resistance By adding appropriate amounts of alloy elements, such as chromium (Cr), molybdenum (Mo), etc., alloy steel can significantly improve the strength and hardness of the steel while maintaining good wear resistance. This is crucial for components such as screws and b... read more
1. Comparison of material properties 38CrMoAIA Nitriding performance: 38CrMoAIA steel is a commonly used nitriding steel with good nitriding performance and mechanical properties. After nitriding treatment, the surface can obtain high hardness and good wear resistance. Mechanical properties: The ste... read more
