Z Control: Flow Front Control (FFC) System
The patent-pending Flow Front Control (FFC) System optimizes the flow front, further allowing control of low internal pressures inside the cavities. This system:
- Takes advantage of the viscoelastic properties of the resin — visco (creep) and elasticity (recovery or pull back) — and allows complete filling without flash
- Provides precision control of screw position to ensure consistent filling, shot-to-shot
- Avoids overfilling, allowing gases to be released and preventing short shots
