Used HDPE 250 and 400mm Pipe Production Machines

Shende Plastic Machinery has been deeply involved in China's plastics machinery manufacturing sector for many years, consistently upholding the principles of innovation-driven development and quality-first approach. Leveraging China's comprehensive manufacturing industry chain, Shende Plastic Machinery boasts a top-tier R&D team and advanced production processes. From precision component machining to complete machine assembly and commissioning, every step strictly adheres to international standards and industry specifications. This deep technical expertise and extensive practical experience ensure the exceptional quality of these used 250 and 400mm HDPE pipe production machines, demonstrating the reliability of Chinese manufacturers.

These two machines each offer distinct advantages, yet both offer exceptional performance. The 250 HDPE pipe production machine, while compact, offers a comprehensive suite of functions. The extrusion system is equipped with a highly efficient and energy-saving single-screw extruder. Its screw features a specially optimized thread design and surface hardening treatment. This not only enables rapid and thorough plasticization of HDPE raw materials, but also effectively improves material conveying efficiency, ensuring stable and efficient extrusion. Even under complex production conditions, it can easily achieve continuous production, meeting the needs of small and medium-sized production runs. Regarding temperature control, a high-precision intelligent temperature control system utilizes multiple temperature sensors for real-time monitoring, keeping extrusion temperature deviations within a minimal range and ensuring precise control of pipe quality.

The 400mm HDPE pipe production machine is even more impressive, designed specifically for medium- to large-scale production tasks. Equipped with a high-torque, high-speed drive and a large-diameter screw, it can process larger batches of raw materials and boasts robust plasticizing capabilities. Whether it's standard HDPE raw materials or specialized materials with fillers or modifiers, it achieves uniform plasticization and stable extrusion. The mold design features a streamlined die head structure and optimized melt flow channels, reducing melt flow resistance and avoiding wall thickness variations caused by uneven pressure. The resulting pipes exhibit uniform wall thickness, minimal roundness error, and superior mechanical properties, making them suitable for applications requiring high-quality pipes, such as municipal engineering and water supply and drainage.

The cooling systems of both devices are truly exceptional. The vacuum sizing chamber utilizes advanced negative pressure control technology, automatically adjusting the vacuum level based on pipe specifications and production speed to precisely define the pipe's outer diameter. The spray cooling water tank utilizes a strategically positioned nozzle array to achieve 360-degree uniform cooling, rapidly dissipating heat from the pipe and preventing deformation.

The traction system also performs exceptionally well, equipped with a servo motor drive that provides strong and stable traction. It automatically adjusts the traction speed based on the pipe's hardness and size, ensuring smooth pipe transport. The cutting device utilizes planetary cutting technology, resulting in precise and fast cutting, resulting in smooth, even cuts, significantly reducing subsequent processing costs and time. Compared to new equipment, Shende Plastic Machinery's used HDPE 250 and 400mm pipe production machines are extremely competitively priced, offering businesses access to high-quality production equipment at only [X]% of the cost of new equipment. Furthermore, Shende Plastic Machinery undergoes comprehensive and in-depth inspections, professional repairs and maintenance, and performance upgrades on every used machine it recycles to ensure stable and reliable performance. A comprehensive after-sales service system also eliminates any worries during equipment operation, truly achieving significant results with minimal investment, allowing businesses to invest more in product R&D and market expansion.

Shende Plastic Machinery's used HDPE 250 and 400mm pipe production machines perfectly combine China's intelligent manufacturing capabilities with high cost-effectiveness. Whether you're a small or medium-sized enterprise seeking flexible production or a large enterprise looking to expand production capacity, these machines offer excellent performance and affordable pricing, making them a valuable tool for enhancing competitiveness and achieving efficient growth.
