5 things you need to know about twin screw extruders

Twin-screw extruder is a machine used to extrude plastics, it has good production efficiency, can meet the needs of different customers, and can extrude almost all types of plastics. The twin-screw extruder has a unique design and high-efficiency extrusion capacity, which can meet the different requirements of customers.

A twin-screw extruder works on the principle that it consists of a pair of twin-screws, one on the inside and the other on the outside, which rotate in opposite directions to extrude plastic. When the twin-screw rotates, the plastic will be extruded by the screw to form plastic parts of a certain shape.

The advantage of the twin-screw extruder is that it has high speed and high production efficiency, can extrude almost all types of plastics, and can meet the needs of different customers. It also has high-efficiency extrusion capacity, which can meet different requirements of customers.

The disadvantage of the twin-screw extruder is that its cost is relatively high, and the maintenance and maintenance of the twin-screw extruder is also complicated, requiring constant replacement of lubricating oil to prevent the extruder from malfunctioning.

Generally speaking, the twin-screw extruder is a very effective extruder, which has high-efficiency extrusion capacity and can meet the needs of different customers, but its cost is relatively high, and its maintenance and maintenance are also complicated.

Working principle of twin screw extruder

Twin-screw extruder is a kind of extruder, which adopts twin-screw pitch structure, which can extrude raw materials into shape.

Working principle: The main part of the twin-screw extruder is the twin-screw, which consists of two screws, and the pitch between them can be adjusted. When the twin-screw rotates, the raw material will be clamped by the pitch between the twin-screw, so that the raw material is extruded into shape.

Important components: The important components of twin-screw extruder include twin-screw, screw bearing, lubrication system, hydraulic system and control system, etc. The twin-screw bearing is responsible for rotating the twin-screw, the lubrication system is responsible for lubricating the twin-screw, the hydraulic system is responsible for controlling the pitch of the twin-screw, and the control system is responsible for the control of the entire extruder.

Application of twin screw extruder

Twin-screw extruder is a general-purpose extruder, which can be used for extrusion of various materials, such as plastic, rubber, silicone rubber, aluminum alloy, copper alloy, steel alloy, etc. It is most commonly used in the manufacture of plastic pipes, plastic fittings, plastic pipes, plastic drains, plastic pipes, etc.
