The Qingdao Huashida heat shrinkable tape production line is composed of a base material extrusion unit, an adhesive coating unit, a heat shrinkable sleeve forming system, and various auxiliary components.
This advanced line offers low energy consumption, minimal noise, adjustable production speed, and a high degree of automation for stable and efficient operation.

It is capable of producing heat shrinkable tapes ranging from 800 mm to 1600 mm in width, which are extensively applied in municipal pipeline systems, oil and gas transmission lines, anti-corrosion steel pipe protection, and thermal insulation pipelines.

Typical applications cover hollow wall winding pipes, steel belt reinforced spiral pipes, plastic-steel composite pipes, double-wall corrugated pipes, PVC-U sewage pipes, PU insulated (black-yellow jacket) pipes, and 3PE steel pipes.

Cross-linked Heat Shrinkable Belt Production Line (model SRSG-800 )

Main Technical Parameters

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: Advanced automation system enables synchronized operation, precise coordination, and user-friendly adjustments.

2.Energy Efficiency: Engineered for low power consumption and extended service life through optimized mechanical and electrical design.

3.Customized Solutions: Production lines can be fully tailored to meet specific customer requirements, with continuous technical support and maintenance.

4.Safety and Reliability: PLC-integrated control system ensures stable performance, enhanced safety, and reduced resource consumption.

5.Comprehensive Service: Provides complete project assistance, including detailed presentations, video demonstrations, market insights, and cost analysis.

1.Heat Shrinkable Tapes - Mass production of high-quality tapes for pipe protection and insulation.
