Qingdao Yifei Plastic Welding Equipment Co., Ltd. is a professional manufacturer specializing in the design and production of electrothermal fusion welding machines, plastic hot air guns, extrusion-type plastic welders (portable plastic welders), electrothermal sleeve production lines, plastic sheet production lines, plastic welding rod production lines, and hot melt tape coating machines. Our products are widely used in various industries such as plastic welding, plastic chemical anti-corrosion, plastic container welding, plastic pipe and fitting fabrication, and electroplating equipment manufacturing. In recent years, we have also developed and produced automatic plastic sheet bending machines, plastic sheet butt welding machines, plastic cutting machines, and plastic sheet engraving machines. We provide high-quality and cost-effective equipment for the electroplating equipment industry, PCB equipment industry, environmental protection equipment industry, and chemical container industry, addressing the issues of poor quality, low speed, safety concerns, material waste, and leakage associated with manual processing of plastic sheets. Our products have been well received and favored by customers both at home and abroad. The RFSJ-16 portable hot air preheating extrusion-type plastic welder is a new type of hot air welder that our factory has carefully developed by introducing advanced technology from home and abroad. Its technical specifications meet those of similar foreign products. It combines hot air preheating with plastic welding rod extrusion, featuring a reasonable structure, easy operation, continuous welding, and high efficiency. The high extrusion pressure significantly increases the welding strength, making it an ideal product for welding various thermoplastic materials. This product integrates hot air preheating and welding rod extrusion, with continuously adjustable electric temperature control for the hot air, an auto-feed air source, and an advanced temperature control system for the extrusion part, directly displaying the melting temperature of the welding rods. The extrusion speed can be easily adjusted, using a screw feeding mechanism. During welding, the high extrusion pressure, along with a sensitive low-temperature protection system, ensures excellent performance. It operates on 220V AC power and can be used for welding plastic sheets, fabricating plastic anti-corrosion pressure vessels, and other thermoplastic products. It is especially suitable for sealing, repairing, and connecting large-diameter hollow wall winding pipes, jointing vertical insulation pipes, PE protective sleeves, elbows, tees, and large-diameter plastic fittings, as well as welding plastic manholes. Since its launch, this plastic welder has been praised for its low price, high quality, and excellent after-sales service. Long-term use by companies such as Taicang Shuangyi, Huada Company of Shengli Oilfield, Changchun Ante, and Zibo Hengyong has resulted in high evaluations, replacing imported products. Our products have been exported to more than twenty countries and regions, including South Korea, Russia, the Middle East, and South Africa. Our factory has also established a dedicated service department to repair imported plastic welding machines, such as the German Munch extrusion plastic welder, Swiss Leister hot air gun, and German Dr. Schröder extrusion welder, solving the problem of high maintenance costs and long repair cycles faced by users through agents. Our factory is located in Aishan Industrial Park, Jiaozhou City, Qingdao, with convenient access to railways, highways, national, and provincial roads. Relying on Qingdao International Airport and Qingdao Port, we have formed a comprehensive and well-connected transportation network, providing a superior geographical location. We warmly welcome both new and old customers to visit and discuss business.
