Environmentally friendly portable plastic extrusion welding machine passed the identification in Qingdao Huashida
An environmentally-friendly portable plastic extrusion welding machine which can be widely used for repairing large-diameter plastic pipes and plastic pipe elbows, cathodes and public waterproofing works, sewage pools, waterproof boards and engineering plastic sheets, etc. In Qingdao Huashida Machine Co., Ltd. successfully passed the expert appraisal and put into mass production. According to the experts, the portable plastic extrusion welding machine independently developed by Qingdao Huashida Machinery Co., Ltd. is small in size and light in weight (only 4 kg), which is easy to carry, especially suitable for field construction work in the field, and is not affected by seasonal climate. The utility model has the advantages of high welding strength, good sealing effect, wide weld seam, large discharge amount during welding, rapid forming at one time, and many economic and technical indicators leading domestically. The welding machine adopts hot air to preheat the surface of the welded base material to the welding temperature, and the softening and fluidity of the surface of the material is enhanced. At the same time, the plastic welding rod is automatically fed into the screw through the feeder, uniformly heated by heating, re-plasticized by screw stirring, and extruded. It is forced out to the surface or groove of the pre-heated soldered base material, and the plasticized uniform solder and the surface of the soldered body are filled with the weld bead shape and re-synthesized, so that the mechanical strength of the welded part is very close. It is widely used by users because it is welded with base metal and is corrosion-resistant, non-polluting and has a long service life.
