China's development of new plastic pipe manufacturing technology

With the wide application of plastic pipes in construction, agriculture, and environmental management, China's plastic pipe manufacturing new technology has also been further developed.
Shanghai Jinwei Machinery Manufacturing Co., Ltd. has recently developed a high-speed and high-efficiency production equipment for random copolymer polypropylene (PP-R) pipe, which can be used as a replacement product for traditional extruders. The equipment has strong material conveying capability and uniform melt flow. The special PP-R head is used to make the material highly plasticized. The pipe is evenly cooled by the high-efficiency sizing cooling system, reducing the internal stress and greatly improving the PP-R pipe. The production efficiency and product performance.
Beijing University of Chemical Technology has introduced plastic pipe precision extrusion molding technology. Its process parameters in the extrusion process fluctuate very little, extrusion equipment working state is stable, can greatly improve the accuracy of pipe extrusion, save raw materials, and can save about 2.4% of raw materials. This technology is especially suitable for the production of medical plastic pipe with small pipe size, complex cross-section, multi-layer and multi-cavity, and high precision.
