Vacuum Cleaner Bag

T/Mould Project in Serial Production

To reach the planned output the production costs of the 3+3-cavities TandemMould were much less then the production costs of a 6-cavities standard mould (because of the needed bigger machine).

The production with two 3-cavities standard moulds would have led to higher production costs, too, because with producing with a TandemMould the injection moulder achieves the double output within the same cycle time as in the standard mould.

The costs for the moulds of the three mould concepts (3+3-cavities TandemMould, 6-cavities standard mould and two 3-cavities standard moulds) would have been nearly the same and did not influence the decision.
