Multi-color Profile Extrusion Line
The composite extrusion process is specifically engineered for multi-layer PP/PE/PS/ABS eco-friendly sheet production. Leveraging an automated batching system and high-efficiency screw design, it achieves synergistic powerful plasticisation and stable conveying. This ensures exceptional product quality while delivering high output and low energy consumption. Optimised screw and screen-changing systems further enhance production efficiency and operational continuity. The process accommodates high-proportion filler additions, not only reducing costs but also enhancing the sheet’s biodegradability and physical properties. This ensures comprehensive stability and reliability throughout the processing stages and in the final product quality.

Production Process
Production Line Composition
The extruder main unit is the core of the production line, responsible for efficiently plasticizing and extruding raw materials to ensure tubing quality and production efficiency. It features a high-precision screw and barrel design, paired with an advanced multi-zone temperature control system to guarantee stability and uniformity during extrusion. Driven by a powerful motor, the unit enables continuous, high-efficiency production and adapts to tubing of various specifications.
The cooling system is a critical component of the line, rapidly cooling and shaping extruded tubing to ensure dimensional stability and surface quality. It consists of stainless steel cooling water tanks and a precision-controlled cooling circulation unit.
This system ensures stable pulling of the tubing from the cooling tank at a constant speed, maintaining dimensional accuracy and consistency. Equipped with multiple traction belts or pulleys and a precise speed control system, it accommodates tubing of varying specifications and wall thicknesses.
These final stages ensure seamless transition from production to packaging:
- Cutting System: Precisely cuts continuous tubing into preset lengths using high-accuracy blades.
- Collection System: Automatically coils or stacks cut tubing for organized storage and transport.
Product Introduction
Technical Background
The foundation of universal sheet extrusion technology stems from the continuous demand for high-efficiency, versatile, and energy-saving equipment in the plastics processing industry. Driven by the rapid development in fields such as packaging, construction, home appliances, advertising, and electronics, the market demand for plastic sheets has surged. To meet the stringent requirements of these industries for product quality, surface finish, dimensional accuracy, and production efficiency, universal sheet extrusion machines have emerged and continue to undergo technological innovation.
Traditional sheet production often faces challenges such as low efficiency, significant material waste, and high energy consumption. In contrast, modern universal extrusion machines achieve efficient and stable production through three major technological breakthroughs: a precision temperature control system, an advanced screw plasticizing device, and optimized die design. This equipment can process a variety of polymer materials, including PVC, PP, PS, PET, and PE, meeting the manufacturing needs of sheets with different thicknesses and specifications. The integration of automation control technology further enhances the equipment’s adaptability to diverse market demands, effectively improves production efficiency, reduces operational costs, and significantly enhances product competitiveness.
Additionally, universal extrusion machines are continuously incorporating energy-saving and environmentally friendly innovations, such as high-efficiency drive systems and low-energy heating devices, ensuring a more sustainable and efficient operational mode. These technological breakthroughs not only advance the process of intelligent and automated production but also establish greener and more sustainable manufacturing practices for the plastic sheet industry.
