As the main equipment of the heat pipe production line, there are mainly two technologies. Today we are going to talk about two major technologies for manufacturing insulation pipe production lines, namely vacuum sizing technology and inner aeration technology. Directly buried thermal insulation pipe production line with Qingdao vacuum sizing technology as the support point, represented by Qingdao Haixi Plastic Machinery Co., Ltd., and a kind of inner inflation method technology. Some traditional backward enterprises are still using inner inflation production technology. Cooling dimension method.

Qingdao Haixi Our company has always been in the spirit of innovation, relentlessly pursued the development and promotion of new technologies, the vacuum sizing technology has continuously improved and improved the quality, the production line uses segmental cooling, and the spiral forced feeding system is designed to achieve fast feeding and high pressure forced compression Plasticization, flow design, after a period of resistance, in a long mixing section, efficient and stable extrusion is achieved, especially suitable for secondary processing of recycled plastics. In terms of control systems, the company has continuously optimized the design and introduced the PLC computer centralized control system, which has increased the degree of automation, stable and reliable production, and reduced human error. Using planetary rotary cutting, the cutting surface is flat, making the production process simple and reliable, the roundness of the outer tube is perfect, the thickness of the tube wall is stable, uniform and smooth, and the cut is neat. When the foaming does not require secondary processing, it can be formed in one processing, with less waste, high output, saving human resources, and very safe. It is an ideal production line for directly buried insulation pipes. This is an important reason why customers trust Qingdao Haixi.



But in the inflation technology, there are too many shortcomings, the equipment is complicated, not only covers a large area, but also has a low degree of automation, high speed but not high efficiency, and there is an urgent need for uneven thickness of the pipe wall. Secondary processing causes waste of raw materials, and has significant safety hazards. The pipeline is prone to blowouts, and it is very likely to endanger people's lives.

There is also the Qingdao Haixi insulation pipe production line. Due to the use of vacuum sizing technology, stable operation, high screw extrusion efficiency, obvious economic benefits, and long service life are a prominent feature. Now there are more and more customers, and they hope to change the existing Qingdao Haixi vacuum sizing technology insulation pipe production line to Qingdao Haixi vacuum sizing technology insulation pipe production line, which fully illustrates the extent of Qingdao Haixi vacuum sizing technology insulation pipe production line .
