Injection/Injection & compression
The injection allows the manufacturing of complex geometry parts in large series, following a simple operating principle. It is essential to inject the material in the tool, retaining the initial structure of the plastic material (to limit shearing). Here are the different steps:
- Beginning of the cycle
- Filling phase (dynamic)
- Switching: filling the cavity or cavities is complete, the screw cannot move forward. Switching is not a step, it is a transition.
- Pressure holding phase or quasi-static phase
- End of dosing
- Relieve of the pressure or suction
The injection parameters are: temperature, pressure, running, speed and time.
Vertical clamping unit / horizontal injection unit
REFFAY SAS has a vertical closing press allowing to manufacture multi-component parts. It also makes possible the overmolding of metal inserts as well as RFID chips, advanced technology. The choice of process and high precision requirements result in a perfect continuity of forms and materials.
