HIPOWER HR‑25KW‑2C Double‑Head HF Conveyor Belt Welding Machine: Cost‑Saving Solution For Cleat, Sidewall & Treadmill Belt Production

Manufacturers producing PVC / PU conveyor belts and treadmill belts are facing common challenges. Buying two independent single‑head HF machines means high capital cost and large floor‑space occupation. Ordinary machines deliver unstable output, causing weak joints, delamination and low tear‑resistance. Sparks during processing easily damage expensive custom moulds. Poor HF‑shielding endangers operators. Standard fixed‑size tables cannot adapt to various belt dimensions for flexible production.

To solve these industry pain points, DONGGUAN HIPOWER LTD launches HR‑25KW‑2C double‑head HF conveyor‑belt welding machine. Two working heads share one HF generator and work alternately, cutting investment cost and workshop footprint. Equipped with European‑style square oscillation cabinet, 5557 anti‑flash controller and advanced HF‑radiation shielding. It is built for welding PVC / PU conveyor belts, cleats, sidewalls and treadmill belts. Power options range from 5KW‑35KW, with comprehensive non‑standard customization available.

Core Technical Features of HR‑25KW‑2C

1. Shared HF‑Generator with Alternate‑Cycle Operation, Cost & Space Saving

Two welding heads share one high‑frequency generator. While one head executes welding cycle, operators load / unload workpieces on the other station. Compared with purchasing two separate HF units, it greatly lowers equipment investment and saves factory floor area. It improves utilization rate of core HF components for high‑volume continuous belt production.

2. European‑Style Square Oscillation Cabinet for Stable Powerful Output

European‑standard square oscillation cabinet is equipped with premium 8T25RA electron tube running on 13.56 MHz industrial frequency. Robust anti‑interference circuit delivers consistent strong HF energy. It realizes deep molecular fusion for PVC and PU belts, cleats and sidewalls. Weld seams feature high tear strength and resist peeling, meeting heavy‑duty industrial belt requirements.

3. 5557 High‑Sensitivity Anti‑Flash Protection for Mould Safety

Built‑in high‑sensitivity 5557 instant anti‑spark system cuts HF power within milliseconds upon flash occurrence. It protects custom belt moulds, electron tubes and internal circuits, reduces mould wear during frequent product change‑over and supports 24‑hour non‑stop workshop operation.

4. Advanced HF Radiation Shielding for Operator Safety

High‑quality HF‑shielding treatment suppresses radio‑frequency leakage to protect long‑term operating staff and meets international workplace safety standards. Air‑intake filter keeps dust and moisture away from electronic assemblies to extend service life.

5. Optional Upgrade: Auto‑Tuning System & Wide Power Selection

Optional ATS auto‑tuning system automatically adjusts energy output according to belt material thickness for consistent welding results for thin or thick PU/PUC belts. Power can be selected from 5KW‑35KW to fit light guide strips up to heavy‑duty thick cleats.

6. Full Customization & Complete ODM/OEM Support

Worktable dimension, upper/lower electrode size and horn travel can all be tailor‑modified. We build widened / extended worktables and special mould‑mounting frames according to belt width and process. Private‑label ODM / OEM service is available. The machine can connect to conveyor production lines to build fully‑automated cleat‑sidewall welding lines.

Frequently Asked Questions

Can both welding heads work simultaneously?

This machine adopts shared‑generator alternate‑cycle design. Only one head outputs HF power at a time. One station welds while the other allows loading/unloading. It increases total throughput without extra HF‑generator cost for mass cleat‑production.

Is it suitable for treadmill running‑belt splicing?

Yes. European‑spec oscillation cabinet provides sufficient energy for PU treadmill belts. Weld seams achieve high tear‑resistance for high‑speed treadmill operation.

Will welding quality vary for belts of different thickness?

Optional ATS auto‑tuning system adapts output power automatically for thin guide strips and thick cleats to keep consistent weld quality.

Can we customize wider table & electrodes for broad conveyor belts?

Yes. Worktable and electrode can be widened / lengthened to match actual belt width for large‑size industrial belt production.

What is the warranty policy for customized machines?

1‑year full‑machine warranty plus lifelong remote‑technical‑support. Engineers provide on‑site installation, commissioning and operator training. All technical inquiries get response within 24 hours.
