A 90/65 high-pressure extrusion line is a specialized industrial production system designed for the efficient manufacture of high-performance plastic pipes and related tubular products. It is widely used in applications that require strong pressure resistance, stable dimensional accuracy, and reliable continuous production. The designation “90/65” typically refers to the main machine and auxiliary equipment configuration, indicating a line optimized for medium-to-large pipe sizes and demanding processing conditions.This extrusion line is built around a high-torque, precision-controlled extruder that melts and conveys polymer materials under stable temperature and pressure conditions. The system is suitable for processing materials such as polyethylene, polypropylene, and other engineering thermoplastics, depending on the required product specifications. Its high-pressure capability ensures that the molten material is delivered consistently to the die head, resulting in uniform wall thickness and excellent pipe quality.One of the key advantages of a high-pressure extrusion line is its ability to maintain process stability during long production runs. The screw and barrel are engineered for strong plasticizing performance, allowing raw materials to be fully melted and homogenized before extrusion. This helps reduce defects such as uneven surfaces, bubbles, or internal voids. The line also typically includes an advanced temperature control system, which precisely regulates heating zones to improve material flow and production consistency.The die head is another critical component of the line. It is designed to distribute molten polymer evenly, ensuring that the extruded pipe has a smooth surface and accurate dimensions. Together with a vacuum calibration unit and cooling system, the line helps the product retain its shape immediately after extrusion. This is especially important for high-pressure pipes, where structural reliability and geometric precision are essential.A complete 90/65 high-pressure extrusion line generally includes automatic feeding, extruder, die head, vacuum tank, spray cooling tank, haul-off unit, cutting system, and stacking or coiling equipment, depending on the final product type. Modern lines are often equipped with intelligent control interfaces that allow operators to monitor speed, temperature, pressure, and output in real time. This improves ease of operation, reduces labor intensity, and minimizes material waste.Energy efficiency and production automation are also important features. By integrating servo-driven systems, optimized screw design, and precise control technologies, the line can achieve high output while reducing power consumption. This makes it suitable for manufacturers seeking both productivity and cost control.In addition, the 90/65 high-pressure extrusion line offers strong versatility. By changing dies and auxiliary devices, it can support different pipe diameters, thicknesses, and production requirements. This flexibility makes it valuable for infrastructure, water supply, irrigation, industrial fluid transport, and other fields where durable piping is needed.Overall, the 90/65 high-pressure extrusion line combines stability, precision, and efficiency. It is a dependable solution for producing high-quality pressure-resistant pipes with excellent mechanical performance and consistent output.
