Shandong launched a new type of aluminum-plastic composite pipe production line Shandong Qingdao Greenhua Plastic Machinery Co., Ltd., the introduction of foreign advanced production technology to develop a new one-step butt welding argon-plastic composite pipe production line, is currently a success. It is understood that the current aluminum-plastic pipe market, there are low welding seam welding strength, explosive cracks, the internal wall is not round, two-step butt welding aluminum plastic pipe easy plastic layer and other quality problems. The environmentally friendly GY14/63 co-extruded one-step aluminum-plastic composite pipe production line developed by Green China Co., Ltd. uses the national 863 scientific and technological achievements and integrates the advantages of both butt-welding and lap-joint welding processes into an integrated production line with ordinary aluminum-plastic composite pipes. Compared with significant performance advantages. Its internal and external plastic, plastic and aluminum ribbon forming mechanism is composed of a channel plate and two co-extruder heads. The plastic and hot-melt adhesives are layered and summarized in the die and the core mold to achieve true co-extrusion and the production line is greatly shortened. The production of aluminum-plastic composite pipe can guarantee the free adjustment of the internal and external wall thickness. The production line breaks through some technical blind spots in the domestic aluminum-plastic composite pipe production line and can completely replace imported equipment. The relevant departments have detected that the technical indicators of the environment-friendly aluminum-plastic composite pipe produced by the equipment have met the requirements of the industry standards and have a promising market prospect.
