PLC For Injection

The PLC-based injection molding system ensures precise control of injection speed, pressure, and position for consistent product quality while supporting multi-zone PID temperature control to maintain uniform plastic melting and stable processing. It is compatible with energy-efficient servo motors, reducing power consumption, noise, and cycle time, and features a user-friendly touch screen HMI for easy parameter setting and real-time monitoring. High-speed PLC processing guarantees accurate and repeatable machine cycles, while built-in safety interlocks protect both operators and equipment.

Key Features

PLCs in injection moulding machines provide precise control over pressure, temperature, and cycle timing to ensure consistent product quality.

  • Ensures accurate control of injection pressure, speed, temperature, and timing for consistent product quality.
  • Supports control of barrel, nozzle, and mold heating zones independently.
  • Enables fast response for clamping, injection, cooling, and ejection cycles.
  • Stores multiple mould programs and process parameters for quick changeovers.
