Extruder is one of the types of plastic machinery, which originated in the 18th century. The extruder can divide the head into right angle head and oblique angle head according to the material flow direction of the head and the included angle of the screw centerline.
Screw extruder relies on the pressure and shear force generated by screw rotation, which can make the materials fully plasticized and evenly mixed and formed through die. Plastic extruders can be basically classified into twin-screw extruders, single screw extruders, rare multi screw extruders and non screw extruders.
Wuxi Lanling plastic machine Co., Ltd. is an enterprise specializing in the production of plastic extruder, wire wrapping machine and wire machine series products. Our company has been engaged in the professional production of extruder since the early 1990s, and has occupied a considerable market at home and abroad. We have an experienced technical team and advanced design means to continuously improve the quality of our products.
Let's share the mechanical principle of extruder.
Add water or appropriate liquid to the raw material powder and keep stirring. The stirred material is extruded from the porous die or metal mesh with high extrusion pressure.
Usually, after the material is put into a cylindrical container, the material is extruded with a screw. After using the frequency conversion technology, the pressure can be controlled so that the most appropriate linear speed can be selected.
