Blok Group has extensive knowledge and experience in the machining of castings, largely owing to the acquisition of the Alkmaarsche IJzer- en Metaalgieterij (later NMA). NMA has been a producer of castings since 1879, so that Blok Group’s expertise in this field is unquestionable.

Blok Group have specialized in machining and supplying iron, steel, RVS and aluminium castings. Re-engineering castings is a recently added specialization of Blok Group, which makes it possible to produce the current castings more (cost-) effectively.
