Sonicam RS6 is drilling tiny vacuum channels inside the moulds.

Advantages:

Holes from Ø 0.3 to 0.8 mm
Robust, very long life-time
User friendly, an essential tool for the mold maintenance to drill holes in engraving and mould shoulder areas as well as for freeing
clogged vent holes

RS6 has three spindles:
Two horizontal on one axis to drill and counter drill without moving the mould
A third vertical one to interconnect the vent holes
The mould cavity is fixed on a 360° swivel table for a better positioning.
The left spindle is very sensitive and makes it easy to drill the smallest diameters with almost no risk of breaking the tool as you can always ensure the drills bits to be always perpendicular to the mold surface even in shoulder areas.
