Heating Element Coil Wrapping Tube Extrusion Production Line
Classification:
This heating wire-wrapped tube extrusion production line is specifically engineered for manufacturing high-performance heating tubing, widely utilised in pipeline systems requiring precise temperature control across medical, industrial, and domestic appliance sectors. The equipment employs synchronised multi-wire heating element and sensor integration technology, precision helical groove structure flexible shaft support rods, and a dual-machine co-extrusion system. This enables multi-wire routing within the tube body, precise spacing control, multi-material co-extrusion forming, and real-time temperature monitoring. These features ensure uniform insulation, structural stability, and consistent forming of the tubing. Heating-wrapped tubing typically demands reliable heating performance, stable wiring spacing, and clean internal cavity treatment. This production line meets these stringent requirements, guaranteeing product compliance with relevant industry standards and safety certifications.
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 development of medical pipe extruder technology stems from the growing demand for high-precision, high-quality medical devices. Advances in minimally invasive surgery and precision therapies require tubing with exceptional dimensional accuracy, biocompatibility, high-temperature resistance, and corrosion resistance. Such tubing is used in blood transfer, drug infusion, and gas delivery, demanding rigorous safety and environmental resilience.
To meet these needs, modern extrusion lines integrate precision temperature/pressure controls and automation, ensuring stable production, efficiency, and consistency. Additionally, eco-friendly materials and energy-saving technologies align with sustainability goals. These innovations drive continuous improvements in meeting global medical industry standards.
