Extrusion system: It consists of a screw and a barrel. The screw is the core component, and its diameter, aspect ratio, and rib shape affect the extrusion efficiency and quality. The barrel provides support and heating environment for the screw, allowing the material to fully plasticize

Transmission system: provides power for the extruder to rotate the screw at a set speed, usually consisting of a motor, reducer, coupling, etc., to ensure smooth transmission and strong power

Heating and cooling system: The heating system brings the material barrel and screw to the temperature required for material plasticization, commonly including cast aluminum heating rings, ceramic heating rings, etc. The cooling system is used to control temperature, prevent material from overheating and degradation, and ensure stable extrusion process

Control system: Achieve precise control of various parameters of the extruder, such as temperature, pressure, speed, etc., to ensure stable product quality and efficient production process. Advanced control systems can achieve automated production, improve production efficiency and product consistency

working principle

When the extruder is working, the plastic raw materials are first automatically added to the hopper, and the raw materials fall into the screw groove of the screw under the action of gravity. As the screw rotates, the raw materials are continuously transported forward and gradually heated and plasticized by the external heating device of the material barrel, ultimately forming a uniform melt. The melt is extruded through the head of the extruder under the push of the screw, and then molded into the desired edge banding shape through the mold. After subsequent cooling, shaping, traction, and coating processes, the final edge banding product is obtained

Characteristics and advantages

High production efficiency: able to achieve continuous and stable production, with a large output per unit time, meeting the large-scale production needs of edge banding strips and improving production efficiency

Good product quality: precise temperature, pressure, and speed control ensure uniform plasticization of materials, high dimensional accuracy of extruded edge banding, good surface quality, and stable physical properties, improving product quality and usability

Wide applicability: By replacing different screws, molds, and other components, edge banding strips of different materials, specifications, and shapes can be produced to meet the edge banding needs of multiple industries such as furniture, doors and windows, and building materials.

High degree of automation: Advanced control systems achieve automated control and monitoring of the production process, reducing manual intervention, lowering labor intensity and production costs, and improving production stability and reliability
