1. Qingdao SHIZE Machinery Equipment Manufacture Co.,Ltd is one of leading manufacturers of plastic extrusion machinery, which is located in the beautiful costal city of Qingdao. It takes 30 minutes to Qingdao international airport or Qingdao seaport. Since its inception, we devote in innovation and management. Recently, we developed a new type of HDPE pipe production line, which is specially designed for meeting demands of heat insulation pipe manufacturer. Because cost is high with conventional production of heat insulation casing pipe, we develop this new machine. Cost is brought down and production is more efficient. This patent is protected. Our patent No.: 201310307252.4
2. At present, heat insulation steel pipe is more popular and market demand is increasing rapidly. HDPE casing pipe is an important part. In traditional way, HDPE casing pipe is large and price of the production machine is high. And with increase of pipe diameter, pipe can not sustain itself because of gravity and become deformed because its thin wall structure. In order to resolve this problem, we developed this new production line. With the same wall thickness, pipe is stronger. And price of the production line is much lower.
