Cooling of the moulds is effected by using direct evaporation of CO2.

After the wax-containing molds are cooled by the cooling tunnel 160 the conveyer carries them to a labeling station 170, after which the finished bait stations are removed from their molds and package.

A glass product molding machine provided with molds (1A, 1B) which each comprise a pair of split molds (11, 12), and with a mold cooling device (X) which cools the molds (1A, 1B) to control the temperature thereof.

Cooling of the molds and thermoformed tank may be performed on a side of the processing lines (10A, 10B).

In the last three years we have worked in particular on a process that optimises the cooling of the moulds.

Simultaneous heating and cooling of molds to balance plastic flow and part solidification

Thus, when conditions permit, one of the system’s two batteries switches to cooling the moulds, relieving the chiller partially or even fully.
