HIPOWER HR-15KW-2C Double Heads HF Welder: Efficient Welding Solution for PVC & PU Conveyor Belt Skirt & Baffle

Manufacturers producing food conveyor belts, industrial transmission belts, treadmill running belts and raised skirt baffles face obvious drawbacks: single-head HF machines limit output, purchasing multiple single units raises cost and occupies large workshop space; split oscillators deliver unstable power, leading to cold weld and delamination on thick belts, while spark flash easily damages moulds. To solve these industry pain points, DONGGUAN HIPOWER LTD launches HR-15KW-2C double-head HF welding machine for industrial belts. Two welding heads work alternately while sharing one HF generator, saving workshop space and equipment investment, specially designed for integrated welding of skirt edges, baffles and partitions on all kinds of industrial belts.

Core Technical Features of the HR-15KW-2C

1. Stable 15KW HF Output with 8T85RB Electron Tube

Equipped with 15KW high frequency generator and premium 8T85RB tube at standard 27.12MHz frequency. European square oscillation box provides powerful steady output for long-hour continuous welding of thick PVC & PU belts and high skirt edges. The integrated weld seam features strong tensile resistance without delamination, meeting heavy-load conveyor application standards.

2. Alternating Dual Heads with Shared HF Unit, Cost & Space Saving

Two heads operate cyclically and share one HF oscillator cabinet, no need to purchase two separate HF machines. It greatly cuts workshop occupation area, equipment investment and power distribution cost. Operators load materials on one station while finishing welding on the other, nearly double output compared to single-head model.

3. 5557 Anti-Flash Protection + Air Intake Dust Filter

Standard high-sensitivity 5557 spark protection instantly cuts HF power once abnormal flash occurs, protecting moulds, oscillator tubes and internal circuits to reduce mould maintenance cost. Built-in air intake filter blocks workshop dust to extend machine service life, supporting 24/7 non-stop mass production.

4. Optimized HF Radiation Treatment for Operator Safety

Professional HF shielding and radiation reduction design lower electromagnetic radiation level, much safer for long-time operators and fully comply with global workshop safety standards, suitable for food and electronic conveyor accessory factories.

5. Optional ATS Auto-Tuning System for Multi-Thickness Belts

Optional ATS automatic tuning system automatically matches HF output power according to belt and skirt thickness, no manual frequency adjustment required for light thin conveyor belts or heavy thick industrial straps, consistent stable welding results.

6. Full Non-Standard Customization + ODM/OEM Support

Upper/lower electrode size, head stroke and max pressure can be customized based on belt width and baffle height, HF power range optional from 5KW to 35KW. Private label ODM & OEM service available, machine structure adjustable to match customer production rhythm.

Frequently Asked Questions

What advantages does dual shared-head machine have over two single-head machines?

One HF cabinet serves two welding heads, cutting procurement cost, floor space and power consumption by half, while output equals two single units with higher cost performance.

Can it weld thick PU conveyor belts with high raised skirts?

15KW power plus European square oscillator delivers sufficient energy for deep penetration welding on thick belts and tall skirt edges, tensile-resistant weld without peeling off.

Do I need manual frequency adjustment for belts of different thickness?

With optional ATS auto-tuning system, the machine auto-adapts material thickness without repeated manual tuning, saving debugging time and stabilizing yield rate.

Is the machine safe for long-hour operation regarding radiation?

Optimized HF shielding structure reduces radiation to meet global safety standards, friendly for long-time operators.

What’s your after-sales warranty policy?

1-year full machine warranty plus lifetime remote technical support, engineers provide on-site installation, commissioning and operator training, all technical inquiries replied within 24 hours.
