Special Purpose Machine - Customized Injection Molding Machine
Small Injection Molding Machine

Features

Kinki’s small injection molding machines are engineered for the high-precision molding of small plastic components. Built on our proven vertical injection platform, these machines deliver stable clamping force and accurate control within a compact footprint.

  • Vertical Clamp & Injection Design

    The vertical design allows easy mold installation and stable mold alignment. Gravity-assisted operation supports accurate material flow and helps maintain consistent molding conditions during each cycle.
  • Precision Injection Control

    Equipped with advanced hydraulic or servo-driven systems, these machines ensure stable injection speed, pressure, and position control. This enables uniform filling and repeatable part quality for high-precision components.
  • Compact & Space-Saving Design

    Small tonnage models feature a compact frame, making them ideal for facilities with limited production space while maintaining high structural rigidity.
  • Flexible Mold & Automation Configurations

    Supporting Single-Slide, Double-Slide, and Rotary Table designs, these machines improve productivity through parallel loading and unloading. They integrate seamlessly with robotic arms, conveyors, and inspection systems for semi- or fully automated lines.
