HIPOWER HR-15KWT Automatic Slide HF Welder: Efficient Welding Solution for Cooler Bags, Waterproof Backpacks & Bike Bags
For manufacturers of cooler bags, waterproof backpacks, bike bags, and outdoor storage bags made of TPU/PVC/eco-friendly plastics, achieving welding and cutting in one step while ensuring weld sealability, waterproof performance, and product yield is a core industry pain point. Traditional equipment requires two separate processes, resulting in low efficiency, large positioning errors, and difficulty in precision processing of eco-friendly materials such as APET and PETG, especially failing to meet the strict waterproof requirements of cooler bags and waterproof bags.
To solve these industry pain points, DONGGUAN HIPOWER LTD has launched the HR-15KWT automatic slide high frequency welding and cutting machine, a purpose-built solution for outdoor products such as cooler bags, waterproof backpacks, and bike bags, equipped with an automatic slide, high-precision temperature control, and synchronous cutting function. It completes welding and cutting in one step, greatly improving production efficiency and product quality.
Core Technical Features of the HR-15KWT
1. 15KW Stable Output for Cooler Bag/Waterproof Bag Materials
The HR-15KWT is equipped with a 15KW high-frequency oscillator and a premium 8T85RB electron tube, operating at the global industry-standard 27.12MHz frequency. Strong and stable power output easily meets the continuous welding needs of materials such as TPU, PVC, APET, PETG, and GAG. The weld strength is close to the base material itself, with excellent waterproof and tear resistance, perfectly adapting to the sealing welding requirements of cooler bags and waterproof backpacks.
2. Automatic Slide + Dual-Station Alternating Operation for Doubled Efficiency
The machine adopts an automatic slide structure with pre-set programs and mechanical interlocks, enabling dual-station alternating operation with automatic slide movement. It greatly reduces manual operations, doubling efficiency compared to single-station equipment. Operators can load materials at one station while completing welding and cutting at the other without waiting, realizing assembly line operation, especially suitable for mass production of cooler bags and waterproof backpacks.
3. Weld & Cut in One Step with 1T-80T Customizable Cutting Pressure
The machine supports synchronous cutting technology, completing welding and cutting in the same station in one step without secondary processing. The cutting pressure is customizable from 1T to 80T, with stable and reliable output and a firm and strong structure. The cut edges are smooth and burr-free, requiring no additional trimming and forming directly, greatly reducing labor costs and scrap rates.
4. High-Precision Temperature Control (±2.5℃)
The machine is equipped with a high-precision temperature control system with a temperature tolerance range of ±2.5℃, adjustable from 30℃ to 200℃. It can accurately control the welding temperature, effectively avoiding material overheating deformation or weak welds/leaks caused by insufficient temperature, ensuring the sealability of cooler bag and waterproof backpack welds to prevent leakage.
5. Multi-Mode Pressure for Different Product Processes
The machine supports two optional pressure modes: pneumatic-oil pressure and pure hydraulic pressure, with a maximum pressure of up to 30T. It can be flexibly adjusted according to the material thickness and process requirements of cooler bags and waterproof backpacks, adapting to various processes such as soft rubber welding, thick material welding, and synchronous cutting. One machine can cover the production of multiple products.
6. High-Sensitivity 5557 Anti-Flash Protection System
A standard high-sensitivity 5557 anti-flash protection system instantly cuts off high-frequency output when abnormal sparking occurs, effectively protecting the welding mold and internal electronic components, reducing production waste, extending the service life of the equipment, and lowering mold maintenance costs, adapting to 24/7 continuous production in workshops.
7. Full Non-Standard Customization + ODM/OEM Support
The HR-15KWT supports comprehensive non-standard customization, including electrode size, slide travel, cutting pressure, temperature range, etc., which can be customized according to customer product requirements. ODM and OEM services are also available to adapt to personalized production scenarios in different industries such as cooler bags, waterproof backpacks, bike bags, and medical ice packs.
Suitable Applications & Compatible Materials
The HR-15KWT is designed for high-frequency welding and synchronous cutting of the following products:
Outdoor products: cooler bags, insulated ice packs, waterproof backpacks, hiking bags, cycling bags, bike bags, wading bags
Eco-friendly packaging: APET, PETG, GAG blister packaging, toothbrush packaging, eco-friendly soft plastic packaging
