Punched skeleton

In the thermoforming process, mainly packaging products (cups, blister packaging, boxes, etc.) are punched out from roll-fed film web or from sheet. The resulting residual thermoplastic plastic skeleton is processed into re‑usable regrind in “RST Thermoform” series granulators.

RST Thermoform granulators are equipped with a special intake section, provided as vertical or horizontal option versions.

Feeding of punched skeletons into the granulator hopper takes place under frequency or dancer arm control, whereby the intake rate is adjusted according to the production machine, so that production fluctuations are compensated.
