Single screw extruder series single screw extruder, can be applied to PP, PE, PS, ABS, PMMA, PVC and other thermoplastic pipe, plate, sheet, rod, profile and plastic pelletizing and other products processing.
Yuanjin Plastic Machinery provides:/ For different raw materials and product specifications, the screw adopts different aspect ratios and compression ratios, and the barrel adopts different structures. Choose the right barrel, screw and drive mechanism to meet the processing needs of high quality products. Features:? ●High output and low energy consumption. ●? Screw geometrical parameters, reasonable design, for different raw materials, make different products, screw has different aspect ratio and structure, to meet the needs of different customers. ●? The heating section of barrel has two structures of grooved and smooth section to meet the needs of different raw materials. Screws and barrels are made of high performance alloy steel, which has the advantages of wear-resistant, corrosion-resistant and high strength. The whole machine is designed to be compact and reasonable, easy to operate. Compact and reasonable design of the whole machine, convenient operation, simple maintenance
Production, plastic machinery should be based on the products of plastic varieties, material state and size of the size of the size of the extruder model selection and regulations.
Raw materials for PVC pellets, with a single-screw extruder extrusion pipe, pipe cross load area and the selected extruder screw area ratio of about 0.30 ~ 0.35.
If the selection of PE, PP and other good liquidity of the plastic, the pipe cross load area and the selected extruder screw area ratio can be larger, it can be taken as 0.4.
Raw materials for the powder
When selecting the twin-screw extruder, the maximum diameter of the pipe should be selected according to the relationship between the type of twin-screw extruder and the maximum diameter of the pipe.
Plastic machinery pipe extrusion molding, should be according to the pipe production specifications to select the appropriate extruder specifications, which can ensure product quality and reasonable use of the extruder.
Large specification extruder production teach small diameter plastic pipe, both increase the manufacturing cost of pipe, and waste of energy.
The production of large diameter pipes by small size extruders increases the difficulty, does not guarantee the quality and accelerates the wear and tear of the equipment.
Different specifications of the extruder used in the production of different diameter pipe size, teach a reasonable choice. Plastic machinery screw speed depends on the size of the extruder, product pipe diameter size. Increase the rotational speed, can improve the output, but not to improve the equipment; increase the rotational speed, the material plasticization is not good, the inner wall of the roughness, the strength of the pipe is reduced.
