HIPOWER HR-15KWG Automatic HF Inner Page Forming Machine: Automated Continuous Welding Solution for Plastic Inner Pages & Soft Bags

Manufacturers producing PVC folder inner pages, card sleeves, ID holders, urine bags and folding plastic boxes face common pain points with semi-automatic machines: low efficiency from manual feeding, easy surface scratching, inaccurate welding dimension, and low-power models cannot meet mass continuous production demand. To solve these industry issues, DONGGUAN HIPOWER LTD launches HR-15KWG automatic high frequency inner page forming machine. It realizes automatic roll feeding and synchronous welding with imported scratch-free feeding system, becoming core automated production equipment for stationery inner pages and soft packaging products.

Core Technical Features of the HR-15KWG

1. Stable 15KW HF Output with 8T85RB Electron Tube for Multi-Material Compatibility

Equipped with 15KW HF generator and premium 8T85RB tube at standard 27.12MHz frequency. High-Q oscillation circuit delivers stable reliable output, compatible with PVC, EVA, TPU, PETG, GAG and other easy-welding plastic materials. Smooth firm weld seams without cold weld or peeling, suitable for soft plastic products of various thicknesses.

2. Synchronous Feeding & Welding with Adjustable Production Speed

Feeding and HF welding run synchronously in continuous assembly line. Full material rolls loaded directly without pre-cutting by hand, greatly improving production efficiency. Operating speed can be flexibly adjusted according to material and process, meeting stable mass production of inner pages and soft bags.

3. Imported Feeding System, Zero Scratch on Material Surface

The feeding transmission system adopts imported wear-resistant soft rubber material, feeding gently and smoothly, completely avoiding surface defects like scratches, pressure marks and whitening. It is especially suitable for high-appearance products such as transparent PETG and high-gloss PVC, improving finished product yield for high-end stationery and packaging.

4. Photoelectric Precision Feeding with PLC Touch Screen Control

Built-in photoelectric sensor accurately controls feeding length for consistent product dimension. PLC HMI touch screen operation enables one-click parameter setting and automatic memory, easy for operators to learn and short changeover time, suitable for flexible multi-spec small-batch production.

5. High-Sensitivity 5557 Anti-Flash Protection for Mould Protection

Standard high-sensitivity 5557 spark protection instantly cuts HF power during abnormal flash, effectively protecting welding moulds and internal electronic components, reducing mould maintenance and replacement cost, supporting 24/7 non-stop factory production.

6. Full Customization + ODM/OEM Support

Electrode size, worktable dimension, power configuration and additional functions are all customizable. Private label ODM & OEM service available. We can design exclusive continuous welding solutions based on customer product size and production rhythm to meet personalized demands of different industries.
