PVC Injection Molding Machine

Standard Double Hydraulic Core-Pulling Device for Fitting Molds:

● This machine comes standard with a dual hydraulic core-pulling system, specifically engineered for complex pipe fitting molds. It ensures smooth internal surfaces and damage-free demolding, enabling stable and highly automated part ejection. This design significantly enhances the dimensional accuracy of pipe fittings and boosts production efficiency, meeting the core demands of high-quality PVC/CPVC fitting manufacturing.

Barrel Air Fan Cooling & PID Temperature Control System:

● Addressing the thermal sensitivity of PVC/CPVC, key barrel zones feature high-efficiency forced air cooling. This system precisely assists heat dissipation, effectively preventing material overheating and decomposition. Integrated with a high-precision PID closed-loop temperature control system, it ensures stable and uniform temperature profiles throughout the barrel, providing the ideal thermal environment for material plastication and guaranteeing consistent product quality.

Dedicated Screw and Barrel for PVC/CPVC:

● The core plasticating unit utilizes a screw and barrel specifically optimized for PVC/CPVC material characteristics. Key features like optimized L/D ratio, compression ratio, and flight design ensure efficient and uniform plastication under gentle shearing forces. This minimizes thermal stress and degradation risks while simultaneously enhancing plasticizing capacity and melt quality, contributing to extended equipment lifespan.

Enlarged Feeding System with High-Torque Motor:

● Equipped with a larger-capacity hopper and an optimized feed throat design, this system effectively prevents bridging or feeding interruptions common with PVC/CPVC powders or pellets. The drive system incorporates a high-torque motor, delivering ample power to ensure stable screw rotation even under high backpressure conditions. This robust setup enables powerful conveyance and thorough plastication of high-viscosity PVC/CPVC melts, markedly improving plasticizing efficiency and stability.

Widened Safety Doors Compatible with Core-Pulling Cylinder Structures:

● The machine's safety doors are specifically widened to fully accommodate the spatial requirements of the large core-pulling cylinders typical in pipe fitting molds. While maintaining strict safety compliance, this design provides greater accessibility for easier mold installation, setup, and maintenance tasks, optimizing workflow and enhancing synergy between the machine and mold.

Intelligent Control Unit with User-Friendly Interface & Rapid Response:

● Featuring an advanced intelligent control system coupled with a high-resolution, intuitive Human-Machine Interface (HMI). The system offers powerful data processing capabilities and rapid response times for convenient parameter setting and monitoring. It supports process recipe storage and recall, providing real-time machine status and diagnostic information, which significantly simplifies operations and boosts production management efficiency and process control.
