PVC Plastic Injection Machine

Standard Double Hydraulic Core Puller for Mold Installation:

● This machine comes standard with a double hydraulic core-pulling system, specially designed for complex pipe fitting molds. It ensures smooth internal surfaces and damage-free molding, allowing for highly stable and automated part ejection. This design significantly enhances the dimensional accuracy of pipe fittings and boosts production efficiency, meeting the essential requirements for manufacturing high-quality PVC/CPVC fittings.

Barrel Air Fan Cooling and PID Temperature Control System:

● To address the thermal sensitivity of PVC/CPVC, the main barrel zones feature high-efficiency forced air cooling. This system precisely helps dissipate heat, effectively preventing material overheating and degradation. Integrated with a high-precision PID closed-loop temperature control system, it ensures stable and uniform temperature profiles throughout the barrel, providing an optimal thermal environment for material plasticization and guaranteeing consistent product quality.

Dedicated Screw and Barrel for PVC/CPVC:

● The core plasticization unit employs a screw and barrel specifically optimized for PVC/CPVC material characteristics. Key features such as optimized L/D ratio, compression ratio, and flight design ensure efficient and uniform plasticization under gentle shear forces. This leads to reduced thermal stress and degradation risks while simultaneously enhancing plasticization capacity and melt quality, contributing to extended equipment lifespan.

Extended 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, providing ample power to ensure stable screw rotation even under high back-pressure conditions. This robust setup enables powerful conveying and thorough plasticization of high-viscosity PVC/CPVC melts, significantly enhancing plasticization efficiency and stability.

Expanded Safety Doors Compatible with Core-Pulling Cylinder Structures:

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

Intelligent Controller with User-Friendly Interface and Rapid Response:

● Features an advanced intelligent control system coupled with a high-resolution, intuitive Human-Machine Interface (HMI). The system offers robust data processing capabilities and rapid response times for convenient parameter setting and monitoring. It supports the storage and retrieval of process recipes, providing real-time machine status and diagnostic information, thereby significantly streamlining operations and enhancing production management and process control efficiency.
