Mollart says that the order was won against strong European competition with the final purchase decision made following drilling trials that led to a massive improvement in the level of production being achieved.
During visits to Chessington to discuss the machine, the customer became aware of demonstrations being run on a Drillsprint LD2-750 two-spindle gundrill. Then, following trials and the machine’s capability to accommodate tight concentricity tolerances, the Drillsprint was also ordered.
The machines are being used to produce moulds for plastic bottles requiring a heavier wall section, incorporating pre-formed cores with accurate and uniform positioning of cooling holes within thin wall section areas of the moulds. Hole sizes are between 3.3 mm and 22 mm diameter by up to 400 mm deep.
