The use of a fleet of cutting-edge machines and highly specialised personnel has enabled us to acquire lots of precious experience in working plastic materials by chip removal. This work method offers the following big advantages: high dimensional precision (application of restricted tolerances), possibility of making prototypes and small series, no costs at all relating to design and manufacture of moulds or equipment in general, execution of component parts that cannot be moulded, requirement by customers of cutting-edge technical and mechanical characteristics, possibility of working hard-to-mould materials.
