Widely used for raincoats, hot water bags, small inflatable toys and blister packaging.Single-head 3-Station Rotary High Frequency MachineThree-station rotating disc enables simultaneous unloading, welding and feeding for non-stop production. The top choice for mass production of blister packages and small medical pouches.Double-head Pneumatic / Hydraulic High Frequency Machine
Two independent welding heads working alternately. Applied to leather embossing, PVC ornaments, leather bags and large-area grain pressing. Hydraulic versions deliver greater pressure for thick materials.High Frequency Simultaneous Fusing Machine (Integrated Welding & Cutting Machine),Finishes welding and edge trimming in one single step, leaving smooth cutting edges without secondary trimming. Equipped with cutting dies as standard, for blister-card sealing, leather labels, automotive leather parts and eco-friendly APET packaging.Large Gantry / Auto Travelling Membrane High Frequency Machine (15KW~150KW),Auto moving welding head along long tracks for continuous long-seam welding. For truck tarpaulins, architectural tension membranes, swimming pool liners, biogas tank membranes and waterproof coiled materials.Double-sided Upper & Lower High Frequency Machine (Exclusive for Heating Pads),Uniform high-frequency output from both sides to avoid cold solder and sparking. Specialized equipment for automotive seat heating pads, physical therapy heating mats and snow melting mats.Full-automatic Assembly Line High Frequency Machine,Integrated functions of automatic coil feeding, continuous welding and winding. For mass production of medical IV bag production lines, waterproof fabrics and industrial belt coils.
2. Classification by Power Rating
Small power: 5KW, 8KW (for small parts and thin films)
Medium power: 10KW, 12KW, 15KW (for raincoats, inflatable toys and small auto accessories)
High power: 25KW, 35KW, 50KW, 100KW and above (for tarpaulins, membrane structures and large inflatable pools)
3. Industry-Specific Specialized Models
Medical high-frequency welding machines, high-frequency machines dedicated to automotive interiors, canvas & membrane welding machines, blister fusing machines, leather embossing machines, high-frequency machines exclusively for heating pads.
二、Core Advantages of High-Frequency Welding (Compared with Hot Welding, Ultrasonic Welding and Gluing)
Molecular-level fusion with superior weld strength and tight sealing
1.Heat is generated inside the materials, allowing plastic molecules of two layers to interpenetrate. The tensile strength of welds is close to that of the raw material. The joints are fully airtight and watertight with zero air or water leakage, making this the only reliable process for inflatable products and medical supplies.
2.Precise heating without workpiece deformation or surface damage
Heat is only generated on the welding zone, while non-welding areas stay unaffected by high temperatures. Ultra-thin films, printed leather and patterned fabrics will not scorch, yellow or wrinkle, delivering an extremely high yield of finished products with intact appearance.
3.Eco-friendly with no consumables and zero glue cost
No solvent adhesives are required, eliminating pungent VOC fumes and complying with environmental standards for medical and automotive industries. There is no risk of delamination caused by glue aging, extending the service life of finished goods.
4.Integrated processes: welding, embossing and cutting in one go
A single mold can simultaneously complete edge sealing, concave-convex logo embossing and trimming. It eliminates secondary cutting and hot pressing procedures and boosts production capacity by over 30%.
5. Adjustable Parameters for Stable Batch Consistency
Power, welding time and pressure can be adjusted independently, with built-in spark protection. It delivers an extremely low defect rate of cold solder and missing welds in mass production, ideal for standardized assembly lines.
6. Fast Cycle Time: 1 to 10 Seconds per Piece
Unlike hot plate welding which requires lengthy preheating and cooling, high-frequency welding generates internal heat instantly. Small workpieces can be formed in just one second, greatly boosting daily output.
7. Compatible with Multi-Layer Composite Materials
It can weld multi-layer composites in one single pass: non-woven fabric laminated with TPU waterproof film, foam with PVC surface, multi-layer mesh fabric, etc. Multi-layer materials fuse integrally without delamination.
