Injection Compression

Basically, the sequences of the Injection Compression Molding process variants are similar and easy to understand because all the process involves is an additional stroke of the clamping unit

1. Close mold to compression gap
2. Inject and fill cavity 80-95% (equivalent to 100% or more of the final volume)
3. Sequential or simultaneous compression by the closing movement of the mold
4. Post-compression (If required), cooling, opening, and ejection

Compression is effected either by the closing movement of the mould only or by the movement of an individual mould element activated by a hydraulic core pull function called core stamping.
