Cast steel part from the nobake process



Sand casting in the furan-nobake process is a particularly flexible casting process for small and medium series volumes. The bonding of the mould material with a synthetic furanic resin enables flexible adaptation of the casting mould in the size and geometry of the required castings. As a result, cast parts with excellent surface quality and dimensional accuracy are created.

Process principle
Patterns made of wood or plastics are often used in the production of moulds with synthetic resin-bonded mould materials. After the moulding of the pattern and the hardening of the moulding material, the pattern is removed from the mould and leaves the mould cavity. Cores for the interior contours and rear sections are manufactured in separate core boxes, and then inserted into the mould. After finishing the mould surface with a refractory ceramic coating, the mould can be assembled and the molten steel can be poured in through a sprue cup.
