HIPOWER HR-15KWG Automatic HF Inner Page Forming Machine: Continuous Roll-Fed Solution for Stationery & Medical Bag Mass Production

Manufacturers producing PVC/EVA/TPU stationery inner pages, card sleeves, medical urine bags and folding boxes face common challenges with traditional single-station HF machines. Manual sheet-by-sheet loading leads to low productivity and positioning deviation. Sheet surfaces easily get scratched and damaged, affecting finished appearance. Frequent product changeovers require lengthy tuning with poor parameter reusability, and continuous mass production lacks stability.

To solve these pain points, DONGGUAN HIPOWER LTD launches HR-15KWG automatic high frequency PVC inner page / plastic bag forming machine. It integrates synchronous HF welding and automatic feeding, with photoelectric induction unwinder/rewinder and imported wear-resistant conveyor. Designed for continuous production of stationery sleeves, card holders, urine bags and box creasing from PVC, EVA, TPU, PETG and GAG materials. PLC touch screen control with recipe storage supports both high-volume production and flexible multi-SKU changeover, with full non-standard customization available.

Core Technical Features of HR-15KWG

1. Synchronous Feeding & Welding with Bidirectional Pulling for Higher Output

Automatic feeding runs synchronously with HF welding. Bidirectional material pulling is selectable with adjustable speed. Compared with manual single-station loading, it realizes fully automatic roll-to-roll production from unwinding, forming to discharging, greatly reducing manual work and boosting productivity for mass production of inner pages and soft bags.

2. Imported Wear-Resistant Conveyor Prevents Sheet Scratches

The conveying system adopts imported wear-resistant rubber material, feeding sheets gently without scratching surfaces. It eliminates scuffs and pressure marks from traditional roller feeding, ensuring high surface finish. It is especially suitable for appearance-sensitive products like card sleeves, file holders and transparent boxes, improving yield and premium feel.

3. Photoelectric Induction with Synchronous Unwinder for Precision

Photoelectric sensor works with synchronized unwinding/rewinding stands to track material position in real time, controlling feeding length and tension precisely. Full-line 联动 of unwinding, welding and rewinding reduces manual alignment, ensuring consistent dimensions during long-run production and avoiding length variation and position deviation.

4. High-Q Oscillation Tube + 5557 Anti-Flash for Stable Durability

Equipped with high-Q oscillation tube at 27.12MHz industrial frequency, delivering stable and reliable HF output. It creates firm, crack-free welds on PVC, EVA and TPU materials. Standard high-sensitivity 5557 anti-flash system cuts HF power within milliseconds upon sparking, effectively protecting moulds and core components, reducing maintenance cost and supporting long-time continuous operation.

5. PLC Touch Screen with Recipe Storage for Fast Changeover

PLC+HMI touch control enables visual adjustment of welding time, temperature and feeding speed. Multiple production recipes can be saved and recalled with one click when switching products, eliminating repeated tuning, shortening changeover time and adapting to flexible multi-item small-batch orders.

6. Full Customization for Diverse Production Needs

Electrode size, worktable width, power rating, feeding width and unwinder structure are all customizable. Dedicated moulds, creasing structures and multi-cavity dies can be designed for specific products. Private-label ODM & OEM service is available. The machine can be integrated with downstream cutting and sorting processes to build complete inner page / soft bag production lines.

Frequently Asked Questions

Can HR-15KWG do creasing for PETG transparent folding boxes?

Yes. Custom creasing moulds are available to perform welding and box scoring in one pass, delivering clear crease lines without scratching for PETG/GAG transparent box production.

Will roll feeding scratch the sheet surface?

The imported wear-resistant rubber conveyor feeds gently without scratching or marking sheet surfaces, ensuring appearance quality for card sleeves and transparent boxes.

Is changeover time-consuming for different inner page sizes?

The PLC system stores multiple recipes. Operators recall saved parameters and adjust feeding speed for fast changeover without repeated trial runs.

Can we customize a wider model for large-size inner pages?

Yes. Electrode size and feeding width can be extended and widened for large-format book pages and big soft bags.

What is the warranty policy for customized machines?

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