Environmentally friendly portable plastic extrusion welding machine has passed expert appraisal
Recently, an eco-friendly, portable plastic extrusion welding machine has been developed and is now widely used in the repair of large-diameter plastic pipes, on-site construction, and the welding of plastic pipe elbows, cathodes, and public waterproofing projects. It is also extensively applied in sewage pools, waterproof boards, and engineering plastic sheets. This innovative welding machine was officially appraised by experts at Qingdao Huashida Machinery Co., Ltd. and has since entered mass production.
According to the expert evaluation, this portable plastic extrusion welding machine, independently developed by Qingdao Huashida, is compact and lightweight—weighing only 4 kg—which makes it highly portable and ideal for field operations. It is not restricted by weather conditions, making it especially suitable for outdoor construction work. The machine offers high welding strength, excellent sealing performance, wide weld seams, and a large extrusion output during the welding process. It forms quickly in one go, with many economic and technical indicators leading in 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. At the same time, the plastic welding rod is automatically fed into the screw via a feeder, uniformly heated, re-plasticized through the screw’s stirring action, and then extruded. It is forced onto the pre-heated surface or groove of the base material, where the molten plastic fills the joint area, forming a strong, uniform weld that closely matches the mechanical strength of the original material.
This welding machine is favored by users due to its ability to bond with the base metal, offering corrosion resistance, environmental friendliness, and a long service life. Its efficiency and reliability make it a popular choice in various construction and industrial applications.
