Computerized Heat Shrink Sleeve Manufacturing System with Basic Film Extrusion Line and Adhesive Coating for PE Hollow Wall Spiral Pipe

The Qingdao Huashida heat shrinkable tape and sleeve production line consists of a base material extrusion line, adhesive coating line, heat shrinkable sleeve forming equipment, and auxiliary devices.
The system features low energy consumption, low noise, adjustable speed, and high automation. It is capable of producing heat shrinkable tapes and sleeves with widths ranging from 800 mm to 1600 mm.

These products are widely used for municipal pipelines, oil and gas pipelines, steel pipe corrosion protection, and thermal insulation pipe systems. The finished heat shrinkable materials feature high adhesion, excellent corrosion resistance, and stable shrink performance, meeting international pipeline protection standards.

Applicable pipe types include:

Hollow-wall winding pipe 

Steel belt reinforced spiral corrugated pipe 

Plastic-steel composite pipe 

PVC-U sewage pipe

PU insulated pipe (black-yellow jacket) 

3LPE steel pipe

Extruder
Adopts a high-efficiency PE/PP single-screw extruder. The extrusion section is equipped with a forced water-cooled feeding zone, which significantly reduces the power consumption of the main drive motor. The extruder features a large length-to-diameter (L/D) ratio screw, providing strong material adaptability and excellent plasticizing performance.

Die Head
Features a coat-hanger type flow channel design with nitrided and polished surfaces. The specially designed thickness adjustment system ensures easy operation and high precision control.

Three-Roll Calender
Depending on the product width, the calender can be configured in vertical or inclined structures. The specially designed internal flow channel of the rollers ensures precise temperature control, guaranteeing excellent surface gloss for geomembranes and waterproof sheets. The high-precision mirror rollers are hard-chrome plated for superior strength and long service life.

Cooling Rack
Supports and cools the freshly extruded heat shrinkable tape, ensuring flatness and uniform thickness.

Control System
 Monitors and adjusts the operational parameters of the production line in real time to ensure stable, safe, and efficient production.

1.Intelligent Control: Highly automated with synchronized operation and easy adjustment.

2.Energy Efficient: Optimized design for low energy use and long service life.

3.Customized Service: Tailor-made solutions with lifelong technical support and maintenance.
