« SP » for the efficient realization of core boxes

« SP » allows the realization of filter housing during the manufacture of the core box before resinification.
The drilling of the core vent housings in the core box is removed. This makes it possible to very significantly reduce the processing time as well as the costs associated with drilling the core vent housings.
The positioning of the core vents can be optimized. The SP is calibrated to 0.2 mm to ensure a core vent good seating.
