1. Clamping unit
- Box type platen structure designed through finite element analysis ensures even stress, less deformation, high precision mold clamping & good rigidty.
- Optimized tie bar design makes sure stable and speedy movement with less impact.
- Lengthened distance between tie bar, mold thickness and opening stroke for bigger mold.
- Optimized Lubrication system ensures precise mold clamping and prolonged life time of mold clamping components.
- Speedy differential clamping function meet the requirement of special movement.
- Multi-ejector pin mode.
- Clamping, injection and ejection position controlled by high precision electronic linear
2. Injection unit
- Twin carriage cylinders ensures even stress and improved injection precision. (Standard feature for K90VT~ K200VT, optional feature for above K260VT)
- fast response injection and sealing construction
- Movable slide guide-way for hopper, more convenient for material change.
- Both PID and Percentage control are available for nozzle temperature control
- 5 stage injection, 3 stage hold pressure, 3 stage melting control to meet the requirement of different products.
- accurate temperature control for material ensures production quality.
3. Power system
- Japanese Sumitomo gear pump, high efficiency, low noise, easy maintenance.
- Servo system package from famous, manufacturers with unit parameter and standard.
- Closed-loop control for pressure and speed, the RPM and the torque can be real-time adjusted, resulting in excellent repeatability.
- Ultra high energy saving. The energy consumption reaches China 1 st grade energy consumption standard of injection molding machine.
- High performance redundant power saving design. The power of motor is up to 10% higher than counterpart in the industry, avoiding motor over-heating or auto stop due to insufficiency of power.
