Integrated Injection Circuit

The specially-designed manifold minimizes hysteresis of hydraulic response and boosts injection response. Additionally, the integrated injection circuit is easy to maintain and therefore saves more time for maintenance.

Two Sets of Independent Accumulators

Injection circuit unit utilizes two sets of independent accumulators. It provides pressures for first stage injection, second stage injection, and intensified injection function. A more stable intensified pressure can be offered by independent intensifying accumulator.

Manual Tuning (Standard)

Achieving Accurate Injection

Injection unit allows adjustments of various parameters, such as pressure buildup at first-stage and second-stage, intensified-pressure value, and injection pressure value. Sensors in each part of our machine return values of injection speed and pressure to controller. Then the controller compares the difference between the actual injection value and the setting value to do fine-tuning. In addition, operator can understand injection situations through curve shown on the display.

Automatic Tuning (Optional)

E.I.V. Electric Injection Valve (Optional)

Injection speeds for first-stage injection, second-stage injection, and intensifying-injection are controlled by three E.I.V. valves respectively, which feature automatic corrections and memory functions.

Injection positioning is controlled by transducer to make sure a highly accurate position.
