Municipal Construction
Adaptation to injection molding machine equipment configuration
Pipe extrusion production line:
We offer extrusion lines for 16–1,600 mm HDPE, PE, ABS, and MPP pipes, covering the full range of diameters from residential to municipal applications. Small-diameter pipes (≤315 mm) are produced using single-screw extruders, while large-diameter pipes (≥710 mm) are manufactured with a twin-extruder co-extrusion configuration. These lines can produce a variety of municipal piping products, including water supply pipes, gas distribution pipes, MPP electrical conduits, and double-wall corrugated pipes. When paired with auxiliary equipment such as vacuum sizing tanks, spray cooling tanks, and planetary cutting machines, they ensure stable pipe formation and dimensional accuracy.
Injection molding machine:
Large two-platen injection molding machines (such as the NEO·HII) are selected, equipped with dedicated high-efficiency plasticizing units and multi-cavity core-pulling systems, to manufacture municipal components such as plastic inspection chambers, rainwater collectors, pipe elbows, and tees. These machines support widened door and window designs or U-shaped door configurations, ensuring product sealing performance and structural strength to meet the stringent requirements of municipal engineering projects.
Auxiliary equipment configuration:
A complementary weightless weighing and batching system is employed to enable online material weighing and precise proportioning, thereby minimizing raw material waste. An integrated online flaring machine and radial measurement equipment are provided to ensure the connection accuracy and dimensional stability of pipe products. For outdoor applications, an UV-resistant modification unit is incorporated to enhance the product’s aging resistance and extend its service life in outdoor environments.
Process Optimization Plan
To meet the requirements for large-diameter, high ring stiffness in municipal piping, the extruder length-to-diameter ratio and power configuration are optimized, and a twin-extruder co-extrusion process is employed to achieve simultaneous formation of thick-walled pipes or structural layers and identification strips. For example, pipes with diameters ranging from 710 to 1,200 mm utilize an SJ120/33 + SJ90/33 co-extrusion configuration, ensuring that the pipe’s ring stiffness meets or exceeds the SN16 standard. In the production of MPP electrical conduit, a segmented cooling process is adopted to control shrinkage and ovality, thereby safeguarding insulation performance; for PVC foamed core pipes, an ABA three-layer structure is used, with the middle layer optionally incorporating recycled materials to balance cost-effectiveness and noise reduction, achieving a noise level reduction of up to 3 dB. At the same time, temperature control and draw speed are optimized and matched, with PLC closed-loop control employed to ensure dimensional stability and a smooth surface finish, thus meeting the acceptance criteria for municipal engineering projects.
Core Advantages
The product range covers a wide diameter spectrum (20–1,600 mm across all specifications), enabling a single production line to accommodate multiple municipal applications and thereby reducing capital expenditure on equipment. The equipment operates with high stability, featuring an intelligent temperature-control and pressure-regulation system that minimizes downtime and ensures timely project delivery. The products exhibit excellent resistance to corrosion, impact, and ultraviolet radiation, making them suitable for complex municipal environments—both underground and outdoor—and delivering a long service life. Customized production is available, allowing equipment parameters and manufacturing processes to be tailored to the specific requirements of each municipal project, such as pressure ratings and pipe diameters, while also prioritizing energy efficiency and resource conservation: the power consumption per production line is 15% lower than that of comparable products, and the waste-heat recovery system can reduce heating energy consumption by 20%, aligning seamlessly with the principles of green municipal infrastructure development.
