Extruder Screw Barrel for Plastic Recycling Machine

The extruder barrel is an important component of the extruder. The following will provide a detailed introduction from aspects such as its structural form, material, function, and application scenarios. 
Structural form
Integral barrel
Features: The integral barrel is machined from a single billet, which makes it easier to ensure higher manufacturing and assembly accuracy. It is also convenient for uniform heating and the installation and disassembly of heating and cooling systems.
Application scenarios: It is widely used in various small and medium-sized injection molding machines and extruders.
Assembled barrel
Features: Generally composed of several barrel sections, it has relatively lower processing difficulty and can be customized according to usage requirements and product types.
Application scenarios: Mainly used in larger-sized extruders and vented extruders.

Function and Features
Material Accommodation and Conveyance: The barrel serves as the accommodation space for materials and works in conjunction with the screw. As the screw rotates within the barrel, it pushes the materials forward, achieving material conveyance.
Plasticizing and Melting: The heating system on the exterior of the barrel conducts heat to the materials inside. Combined with the gradual reduction of the screw thread volume, the materials are subjected to various forces such as compression, tumbling, and shearing, resulting in uniform mixing and plasticizing. The materials gradually melt into a viscous flow state, completing the plasticizing process.
Precise Temperature Control: The barrel is equipped with heating and cooling devices, such as electric heating elements and water cooling systems, which can precisely control the processing temperature of the materials, ensuring they are in an optimal processing state and meeting different process requirements.
Ensuring Uniform Material Mixing: In coordination with the screw, through the rotation of the screw and the confinement of the barrel, the materials are thoroughly mixed and dispersed within the barrel, achieving uniform physical and chemical properties and enhancing product quality.
