Coating Extruder Production Line
This Coating Extruder Production Line is specifically designed to uniformly coat one plastic material onto substrates (e.g., metal, rubber, fiber) to form high-performance composite materials. Utilizing advanced extrusion technology, it ensures precise thickness and uniformity of the coating layer while achieving strong adhesion between the composite layer and substrate. Widely used in cables, wires, pipes, and other fields, it produces corrosion-resistant, wear-resistant, and high-temperature-resistant composite products such as cable sheaths, automotive components, and industrial pipes. The machine enhances mechanical strength and durability while allowing customizable coating materials and thicknesses to meet diverse industrial needs. Its efficiency and stability make it indispensable in modern manufacturing.

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.
