WELD-750-Zipper is a high-frequency welding machine specially developed for PVC waterproof zippers and tarpaulin zippers. It supports adjustable power from 10KW to 25KW and is equipped with a high-sensitivity arc suppressor to avoid scorching during welding. The wide curved worktable enables continuous processing of large-size zippers for roller blinds, tents and waterproof bags, with freely adjustable welding time and pressure. Weld seams are tight, waterproof and crack-resistant after repeated washing. The intuitive control panel, foot switch and mobile casters allow easy single-person operation. Compatible with thermoplastic coated fabrics like PVC and TPU, this machine is widely applied in production lines of outdoor sunshades, inflatable goods and waterproof pouches, effectively boosting output and lowering rework rates.
