Recently, an eco-friendly, portable plastic extrusion welding machine has been developed and is now widely applicable in the repair of large-diameter plastic pipes, on-site construction, and welding of pipe elbows, cathodes, public waterproofing projects, sewage pools, waterproof boards, and engineering plastic sheets. This innovative device has successfully passed expert evaluation at Qingdao Huashida Machine Co., Ltd. and has now entered mass production.
According to industry experts, the portable plastic extrusion welding machine independently developed by Qingdao Huashida Machinery Co., Ltd. is compact and lightweight, weighing only 4 kg, making it highly portable and ideal for field operations. It is not affected by weather conditions, which makes it particularly suitable for outdoor and remote construction sites. The machine offers high welding strength, excellent sealing performance, a wide weld seam, and a large extrusion output during the welding process. It also allows for rapid one-time forming, with many economic and technical indicators leading the domestic market.
The welding process involves using hot air to preheat the surface of the base material to the required welding temperature, enhancing the softening and fluidity of the material. Simultaneously, the plastic welding rod is automatically fed into the screw via a feeder, uniformly heated, re-plasticized through screw stirring, and then extruded. It is forced onto the pre-heated surface or groove of the base material, where the uniform plasticized solder fills the weld bead shape and re-synthesizes with the base material, resulting in a welded joint with mechanical strength that closely matches the original material.
Due to its ability to weld directly with the base metal, this machine is corrosion-resistant, non-polluting, and offers a long service life. As a result, it has gained widespread acceptance among users for its reliability, efficiency, and environmental benefits. Its versatility and performance make it an essential tool in modern construction and maintenance projects involving plastic piping systems.
