Plastic handle forming welding machine combines plastic handle punching, pail ear punching and ear welding together, carving a reputation as pioneers in plastic handle production field. Meanwhile, rivet-like ear and plastic strip, components for pail handles, are punched and welded directly in this machine, which leads to decreased material cost and labor cost. Besides, the machine introduces cams for conveying and transmission system, as well as electric cylinder feeding system and Siemens motion control system to make it run more accurately, flexibly, smoothly with high speed.
