About The Extruder

2024-11-06 10:46:55

The extruder is the main equipment for the production of light alloy (aluminum alloy, copper alloy and magnesium alloy) pipe, rod and profile. The types of extruder include metal extruder and plastic extruder, among which the plastic extruder can be divided into double screw extruder and single screw extruder.

Working principle of the extruder

The working principle of the extruder is the pressure and shear force generated by the rotation of the screw rod, so that the material is fully plasticized and is evenly mixed, and then formed through the mouth mold. The main components of the extruder include the mechanical part, the hydraulic part and the electrical part.

Application field of the extruder machine
Extrsors are widely used in industrial fields, especially in the production of light alloy tubes, rods and profiles. In addition, plastic extruder are also widely used in the plastic processing industry.

Structural composition of the extruder
The structure of the extruder includes the mechanical part, the hydraulic part and the electrical part. The mechanical part mainly includes screw, drum and mold; the hydraulic part is responsible for providing pressure and power; and the electrical part controls the operation of the whole equipment.

Specific types and characteristics of the extruder
horizontal extruder‌：
The movement direction of the main working parts is parallel to the ground level.
Advantages: the equipment layout is flexible, suitable for mass production
Disadvantages: occupy a large area, easy to produce uneven wall thickness.

Vertical extrusion machine:‌
The movement direction and discharge direction of the main components are perpendicular to the ground.
Advantages: small area, suitable for the production of small size pipe and hollow products
Disadvantages: you need a higher plant and a deeper pit

Advantages of extrusion machine
The advantages of the extruder mainly include the following aspects:
High efficiency production: the extruder can efficiently produce light alloy tubes, rods, profiles and other products. From the manual hydraulic pressure press of several megabytes to the automatic oil pressure press of two hundred megabytes, the ability of the extruder has been greatly improved, which can reflect the production technology level of an enterprise

High degree of automation: modern extruder is usually equipped with lifting equipment, high degree of automation, can reduce human operation, improve production efficiency

Energy saving and environmental protection: fully closed open bag unloading design can eliminate dust, reduce environmental pollution.

Efficient molding: some designs, such as the synergistic effect of the main cylinder and the side cylinder, can achieve more efficient molding in the primary processing, reduce the processing times, and save time and resourcesh

Temperature control: through the high temperature hot oil injection of the liquid cavity, ensure the constant temperature of the forging in processing, improve the quality of the forging, and reduce the cost of secondary heating in the later period.

Wide range of application: extruder is not only used in the production of aluminum alloy, copper alloy and magnesium alloy and other light alloy products, but also can be used in the production of high-performance industrial aluminum, such as hard aluminum and super hard aluminum alloy bar, profile, etc

Technology maturity: Extrusion technology originated in the United Kingdom in 1797. After years of development, the technology has been quite mature, widely used in automotive, aerospace and other fields.
