Import Drifting Bag Surface Hf Welding Machine — Buy in wholesale FOB from Supplier in China

The Donguan Kailong Machinery Co., Ltd Drifting Bag Surface HF Welding Machine is a dual-head high-frequency welding system available in 5kW and 8kW models, operating on 380V power with silicon diode rectifiers and 7T85RB or 7T69RB vibrational tubes. It delivers maximum electrode pressure of 350kg or 450kg respectively, with an active horn size of 60mm and a plat size of 350mm by 700mm. The machine features adjustable welding time from 0 to 10 seconds and temperature control ranging from 30°C to 300°C, enabling precise seam formation on thermoplastic materials.

The machine uses imported components and a high-Q vibrational tube to ensure stable RF output, reducing energy loss during welding. Pneumatic pressure application reduces manual effort and improves consistency, while dual-circuit counter-action allows automatic head switching between operations. A high-sensitivity fire prevention system protects the mold from overheating, and temperature control ensures uniform weld integrity across batches. These features align with standard industrial requirements for continuous production of waterproof bags, inflatable products, and sealed containers.

This equipment is commonly purchased by manufacturers of waterproof bags, water sports gear, medical pouches, and industrial tarpaulins who require consistent, high-strength seams. Buyers typically source it for batch production lines requiring repeatability and minimal operator intervention. Packaging is standard industrial crate with foam padding. Lead time is not specified; buyers must confirm delivery schedules directly. Incoterms and payment terms are not listed and should be negotiated with the supplier.
