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
Causes of wear 1. Material friction: When the exhaust screw of the extruder rotates in the barrel, the friction between the material and the screw and barrel will cause the working surface of the screw to gradually wear. Especially when the material contains fillers such as calcium carbonate and gla... read more
1. Plastics field Special requirements: Plastics are of various types, including polyolefins, polyamides, polystyrene, etc. Different plastics have different characteristics such as melting temperature, viscosity, thermal stability, etc. The exhaust screw should adapt to the extrusion process of dif... read more
