Used HDPE 63 Double-outlet Pipe Production Machine

As a professional Chinese manufacturer deeply engaged in the plastics machinery field, Qingdao Shende is well aware of the challenges of producing small-diameter dual-exit pipes. To address the high-volume, high-precision requirements of HDPE63 pipes, the R&D team has optimized dual-extrusion production technology. Using a twin-screw parallel extrusion design, the parameters of the two extrusion channels are independently controllable, enabling simultaneous production of two pipes, increasing production capacity by 80% compared to single-extrusion equipment. The independently developed micro-sizing sleeve achieves dimensional accuracy of 0.05mm, ensuring a diameter error of no more than ±0.2mm for both pipes, completely resolving the issue of "one good, one poor" quality in dual-extrusion production. A synchronized pulling system ensures consistent pulling speeds for both pipes, preventing wall thickness variations caused by uneven stretching. These detailed designs, which embody China's intelligent manufacturing, allow second-hand equipment to meet the high standards of mass production.

The quality of used equipment, a major concern for customers, is completely eliminated at Qingdao Shende. Each recycled HDPE63 dual-extrusion pipe machine undergoes a quality inspection process that's "comparable to new." The inspection team uses precision equipment like laser diameter gauges and pressure sensors to meticulously check screw wear and heating coil power on both extrusion channels to ensure consistent performance. Technicians disassemble the equipment and replace all wearing parts on both channels with genuine parts, even small components like bearings and seals. Finally, a 72-hour continuous dual-extrusion trial run is conducted, during which every pipe produced passes pressure tests and wall thickness uniformity inspections. Only pipes with a 100% pass rate are released. Through this refinement, HDPE63 pipes produced using used equipment fully meet the stringent standards for building plumbing, electrical wiring, and other applications.

Stable performance is the hallmark of this equipment and the key to alleviating production anxiety for our customers. The equipment's dual-outlet system has been professionally calibrated, keeping temperature and pressure fluctuations in both channels within ±1°C and ±0.5 MPa, respectively. It maintains virtually no deviation in pipe dimensional parameters during 8 hours of continuous production. The variable frequency motor and reducer used are both factory-installed and, after load testing, have proven trouble-free operation for 300 hours, eliminating the constant worry of minor malfunctions. A building materials company uses this system to produce conduit for electrical wiring. The dimensional consistency of the pipes produced in batches far exceeds customer requirements, reducing returns to zero and securing long-term supply orders.

When it comes to customer concerns about cost, the advantages of used equipment are clear. While a new HDPE63 dual-outlet production line would cost hundreds of thousands of yuan, Qingdao Shende's used equipment has been reduced by 60%, allowing it to be purchased for around 200,000 yuan, and comes with the same technical support as a new machine. A pipe manufacturer in Zhejiang province not only saved a significant amount on equipment investment but also rapidly captured the local home improvement market with its dual-outlet production capacity, earning back its investment in just three months. As a professional Chinese manufacturer, Qingdao Shende also provides comprehensive after-sales support: During on-site installation, engineers will provide specialized training on parameter adjustment techniques for dual-output production to ensure workers master "dual-output synchronization." A 24/7 online technical team provides remote guidance for any issues encountered during operation, and on-site repairs are available within 48 hours in East China. Common accessories, such as sizing sleeves and traction wheels, are well-stocked in the warehouse and can be delivered the next day, ensuring no delays in mass production.

Qingdao Shende's used HDPE63 dual-output pipe production machine leverages the technical expertise of a professional Chinese manufacturer to address the pain points of customers who are hesitant to expand production and concerned about the cost and instability of dual-output systems. Choosing this machine allows companies to achieve a cost-effective capacity increase while gaining market trust through stable performance, easily gaining an advantage in the competitive small-diameter pipe market.
