Number, location of stations can adjust to application

As such, the number of stations, their individual positions and their function can be selected as needed, Boucherie noted. This is said to result in a maximum of mould layout flexibility. Versions for four or more components can be built with or without intermediate cooling stations between injection stations when desired, the company explained. It explained that one or more ejection stations or positions for pre-made structures can also be added for insert moulding. Less complicated applications that suit this type of tool include two-component moulding with maximum cavitation in a stack configuration, or combined with any of the aforementioned extra functions.

Mould design cuts complexity of connection to injection unit

Since the central cube is stationary, the interface with the injection moulding machine can be kept simple, the designer said, explaining that in this respect, it is comparable to a regular stack mould. The stationary central section allows for easy and ample supplies of cooling water, compressed air, electrics and other systems without the need for delicate rotating couplings, the company noted. The valve-gated hot-runner system has hydromechanical activation as standard for the valve pins, a system Boucherie said has been in its moulds for over 15 years.

All necessary motion controls for the servo-motors and other components are made in-house and come in a separate control box with the mould as one fully integrated package.
