Description
Our industrial heat shrink tunnel is the ideal finishing solution for wire harness packaging lines. Designed to operate seamlessly downstream from L-bar sealers or sleeve wrappers, this tunnel delivers fast, uniform, and consistent shrinking results for polyolefin films.
This high-performance unit provides consistent, professional-grade shrink results across various product configurations.
Key Features:
Uniform & Consistent Shrink – Advanced forced hot air circulation technology ensures even heat distribution from all sides, eliminating cold spots and achieving a wrinkle-free, professional-grade finish on every wire harness bundle.
High-Speed Continuous Operation – Features an adjustable conveyor belt system for continuous feeding of sealed products, maximizing throughput and making it ideal for integration into semi-automated or fully automated packaging lines.
Precise Temperature Control – Ensures accurate thermal management for consistent results and prevents film damage due to overheating.
Energy Efficient Design – Heavily insulated chamber and focused airflow design minimize heat loss, reducing energy consumption while maintaining a cooler external operating environment.
Versatile Application – Suitable for shrinking PE, PVC, and POF films. Easy-to-adjust speed and temperature settings accommodate various film types and thicknesses.

| Option | Description |
| Take-out Robotic Arm | Automatically picks up and unloads finished wires for continuous unmanned operation; works with collection trays or conveyors. Requires a table on the equipment for installation. |
| Wire Twisting Unit | Twists and compacts copper strands after stripping to prevent stray or reversed strands, facilitating terminal insertion and crimping while improving first-pass yield. Effective for small-gauge wires (≤ 3 mm² cross-section); does not produce noticeable twisting effect on stiffer copper strands. |
| Middle Stripping Device (Window Stripping) | Creates a T-shaped slit on the wire for middle (window) stripping at any position — can be located at the middle or at both ends of the wire. Available in electric and pneumatic versions. |
| Production Management System | Two modes: standalone management (output statistics and job management on a single machine) and multi-machine networking (centralized order dispatching and capacity allocation across multiple machines). |
| Equipment | Function | Key Notes | Product Link |
| Inkjet Printer | Synchronized online printing of serial numbers, characters, and barcodes on the wire surface. | Clear, high-contrast print quality; requires regular consumables (ink and solvent). | View Product |
| Laser Marking Machine | Synchronized online laser marking on the wire surface — no ink required. | No consumables, maintenance-free; marking color depends on wire insulation material and varies accordingly. | View Products |
| Wire Prefeeder | Automatic wire payoff with constant tension, preventing pulling damage from heavy spools and ensuring stripping accuracy. | Compatible with spools of various weights; smooth and steady feeding. | View Products |
| Wire Stacker | Automatically stacks finished wires neatly for easy collection, bundling, and packaging. | Supports extended unattended operation; stacking and collection are fully automatic. Requires a table on the equipment for installation. | View Products |
| Wire Coiler | Automatically coils finished wires into loops for easy bundling and packaging. | Requires an operator nearby to remove finished coils promptly. Requires a table on the equipment for installation. | View Product |
The PK-H40, PK-H50, and PK-H60 are industrial heat shrink tunnels designed for wire harness packaging lines. They are used downstream from L-bar sealers or sleeve wrappers to shrink polyolefin films onto products.
PK-H40: 350*150mm product size, 5.5KW, 220V, 60kg. PK-H50: 450*250mm, 11KW, 380V, 90kg. PK-H60: 550*250mm, 11KW, 380V, 100kg. All feature 0-15M/MIN conveyor speed and support POF/PVC films.
Key features include advanced forced hot air circulation technology for even heat distribution, precise temperature control to prevent film damage, energy-efficient insulated chamber design, and adjustable conveyor speed for various film types.
The machines support POF and PVC shrink films. Conveyor load capacities: PK-H40 (15KG), PK-H50 (20KG), PK-H60 (20KG). Conveyor options include mesh belt, chain roller, and Teflon.
PK-H40: 220V, 5.5KW, 110*56*66cm, 60kg. PK-H50: 380V, 11KW, 160*66*76cm, 90kg. PK-H60: 380V, 11KW, 160*76*76cm, 100kg. They require dedicated floor space.
