Technical Overview

The injection compression molding process involves injecting liquid or semi-solid materials into a mold cavity, then applying pressure to ensure the material fills the mold completely before being cooled and demolded.

This method combines the benefits of injection and compression molding, offering precise control over temperature, pressure, and material flow. Our molding press system features an advanced temperature and pressure regulation system, allowing for highly consistent processing conditions. This results in excellent dimensional accuracy, surface quality, and material integrity, particularly important for thermoset plastic products and high-performance composite parts.

Features of SMC Injection Compression Molding Press
  • Material is injected after mold clamping, enabling dense material structure, high dimensional accuracy, and minimal flash.
  • Fast mold opening and closing with strong clamping force reduces cycle times and minimizes mold wear.
  • Equipped with a proportional servo system for precise, stable motion and consistent molding pressure.
  • Heating platens use segmented temperature control for uniform heat distribution.
  • Supports long-term use at 50°C to 400°C for thermoset and composite processing.
  • Reliable heat insulation design ensures low thermal loss and energy efficiency.
  • Includes Siemens control system thermal plane monitoring and accurate fault detection for heating components.
  • All process parameters are continuously logged for quality assurance and repeatability.
  • Integrated mechanism allows for mold platform retraction and tilting, improving ease of operation and part removal.
