A recent export order won by Mollart Engineering for a four-spindle Omnisprint deep-hole drilling machine has enabled a bottle-moulding company in Mexico to increase its penetration rates in cast-iron moulds by 500% when drilling cooling holes in a series of bottle moulds.

Such has been the success of the operation, that the customer has ordered a second machine. The series of cooling holes measure between 4 and 9 mm, by 400 mm deep, and feature a straightness tolerance of 0.2 mm. These are now drilled at a feed rate of 600 mm/min.
