Rotary machines with 8-10-18 stations for processing semi-expanded materials and/or for co-injection moulding, clamping power from 70 to 1200 KN.
Structural foam moulding of any thermoplastic material involves the use of foaming agents. This process reduces the density of bulky items and thus allows important savings of material in terms of weight and cost. However thick parts require a long cooling time ranging from 2 or 6 minutes so a multi-station rotary closing system is the appropriate solution.

One of the advantages of a rotary closing system is that it provides the best efficiency of the injection group which constantly and regularly fills the moulds one after the other. The residence time into the barrel is reduced to a minimum which assures a better quantity control and greater repeatability from shot to shot. On the carousel one can use dissimilar moulds of items varying in shape and weight since each station can be set up with differing parameters. One or more stations can be skipped automatically whenever a mould is not available or when a given production quantity has been reached.
Due to added environmental pressures from state regulations structural foam as well as co-injection when associated with a multi-station system is an interesting solution to the recycling problems whether industrial scraps or the more difficult mixed plastic or post consumer wastes are involved.
