Industrial piping
Adaptation to injection molding machine equipment configuration
Dedicated extruder:
A large-capacity twin-screw extruder with a length-to-diameter ratio of 36:1 is employed, equipped with wear-resistant screws and dedicated dies, and compatible with corrosion-resistant resins such as HDPE, PP, and CPVC for the production of industrial conveyance pipelines. This setup enables stable extrusion of thick-walled pipes with wall thicknesses exceeding 50 mm, and when paired with a high-precision vacuum calibration system, it ensures tight dimensional accuracy and excellent roundness.
Injection molding machine:
High-pressure injection molding machines are employed, equipped with JI dual-stage extrusion-injection units and high-power ceramic heating systems, for the production of industrial pipeline fittings such as corrosion-resistant elbows, tees, and flanges. This ensures tight connections between fittings and pipelines with no leakage. Certain models can be configured with hydraulic core-pulling mechanisms, making them suitable for manufacturing complex-structured fittings and enhancing both product sealing performance and structural strength.
Auxiliary equipment configuration:
A complementary raw-material purification system removes impurities from the feedstock, preventing scratches on the inner pipe walls that could impair conveyance efficiency; an online pressure-monitoring device is installed to continuously track the pipeline’s pressure-resistance performance, ensuring compliance with industrial pressure standards; high-precision cutting equipment is provided to enable precise pipe cutting, minimizing joint misalignment; additionally, an internal pipe-wall polishing unit is incorporated to enhance the efficiency of media transport.
Process Optimization Plan
Optimize extrusion process parameters by adopting a “low-temperature plasticization, slow extrusion, and staged cooling” approach to prevent raw-material degradation, enhance the pipe’s corrosion resistance and high-temperature performance, and ensure compatibility with industrial operating conditions ranging from –40°C to 120°C. For thick-walled pipe production, refine the die flow-channel design through simulation-based optimization to achieve uniform material distribution, thereby eliminating defects such as uneven wall thickness and internal voids; additionally, employ co-extrusion technology to apply a wear-resistant, corrosion-resistant coating on the inner pipe wall, further extending service life. In injection-molded fitting production, optimize injection pressure and holding time to ensure a dense, defect-free part structure free of sink marks and cracks, while rigorously controlling the raw-material formulation by incorporating corrosion- and aging-resistant additives to improve fitting compatibility. Furthermore, strictly control particle moisture content and cleanliness, coupled with upstream drying and precision filtration equipment, to guarantee both product appearance and mechanical strength.
Core Advantages
The equipment is highly specialized and tailored to withstand harsh industrial operating conditions, enabling the production of high-pressure, corrosion-resistant, and high-temperature–resistant industrial pipelines and fittings to meet the diverse conveying requirements of various industries. The products exhibit exceptional dimensional accuracy, with wall-thickness deviation controlled within ±0.2 mm, ensuring tight joints and eliminating leakage risks to safeguard industrial production safety. Production efficiency is high, as the twin-screw extruder supports continuous operation and robust batch supply capabilities. Customization is also available: raw-material formulations and process parameters can be adjusted in accordance with the characteristics of the process media—such as corrosivity, temperature, and pressure—to precisely meet the specific needs of industries including chemicals, petroleum, and power. In addition, the modular design of the equipment facilitates easy maintenance and process upgrades over the equipment’s service life.
