Belgian mould house Boucherie, Izegem, said it has introduced a completely new concept in the field of multi-component injection moulding with the recent delivery of its first “Flexi-Cube” mould.

Parts take the first step on a five-stop tour

The shop said the first mould of this type was delivered for a three-component handle in 24 cavity layout. This particular model is a 5-station mould comprising the following:

  • Station 1 – 24 cavities for injecting the first material
  • Station 2 – Cooling
  • Station 3 – 24 cavities for injecting the second material
  • Station 4 – 24 cavities for injecting the third material
  • Station 5 – outside the mould for product ejection or removal during an active moulding cycle.

Although the product made with this mould features a relatively large wall thickness, an overall cycle time of only 15 seconds was achieved, the company noted. It explained that the core of this mould is a stack design with a central, stationary cube around which various stations are provided. They are linked by a transport-system that travels around the cube. For this purpose, a solid track is installed upon which holders with moulded parts travel. These holders are moved by means of servomotors that allow them to travel over different distances.
