(85-650 Ton / 750-3200 Ton)

Feature

  1. High injection rate, which reduces internal press.
  2. High output hydraulic system, it provides outstanding performance
  3. Enlarged clamping stroke to meet with larger stroke requirements
  4. Low noise level hydraulic circuit
  5. Japanese made computer controller specially designed for injection moulding
  6. Proportional power saving pressure and flow hydraulic system, which is power saving, fast cycle, low noise and low maintenance cost

Control system

  1. Japanese made computer controller.(specially designed for injection moulding).
  2. Fine-tuning capability of parameters during the moulding process.
