MPP (Modified Polypropylene) power pipe equipment is the core equipment for producing high-performance power cable protection pipes. Yongte MPP Electric Conduit Pipe Making Machine boasts advantages such as high production efficiency, high automation, energy saving and environmental protection, and easy operation and maintenance.
1. Extrusion System: Efficient Plasticization of High-Viscosity Materials
Single-Screw Extruder: Utilizing a 33:1 length-to-diameter ratio single-screw design, the screw is equipped with a barrier section and a mixing head. The barrel features a slotted structure, enabling uniform plasticization of MPP materials at high temperatures of 190-220℃, with a capacity of 150-300 kg/h.
2. Die and Mold System: High-Precision Molding Guarantee
Spiral Composite Die Head: Employing a spiral flow-dividing die design, the die cavity pressure is low (≤5MPa), and the melt temperature is uniform (temperature difference ≤2℃). The produced pipes achieve an inner wall smoothness of Ra0.2μm, reducing cable penetration resistance.
3. Vacuum Calibration and Cooling Technology: Equipped with a three-dimensional adjustable vacuum sizing water tank, it controls the vacuum level (-0.06~-0.08MPa) and spray cooling (water temperature 15-25℃) to minimize pipe roundness error and outer diameter tolerance. It also employs a butterfly sizing sleeve with a water curtain, making it particularly suitable for rapid cooling of small-diameter pipes.
4. Automated Control: Doubling Production Efficiency
PLC + Servo Drive: Achieves fully automated control of the entire process from raw material proportioning, extrusion speed, shaping pressure to cutting length, with a production speed of 0.5-5m/min, increasing efficiency by 30% compared to traditional equipment.
