Automatic green sand moulding
DISA and HWS automatic lines make series castings in green sand, from 0.10 kg up to 250 kg, with PN-ISO 8062 tolerances CT9 to CT11 on the DISA lines.
How the process works
Green sand bonded with bentonite is pressed into moulds. The moulds are poured with liquid metal and left to cool, then the castings are separated and the sand is recycled for the next cycle.
The line is automatic and one operator can monitor it, which keeps labour cost per part low and quality repeatable from the first casting to the last.

Questions
What weight and size can the automatic lines cast?
The DISA lines cast parts from 0.10 to 47 kg, up to 600 × 450 × 350 mm. The HWS lines cast parts up to 250 kg in flasks up to 1050 × 800 × 320 mm.
Which tolerances do the DISA lines achieve?
Castings are made to PN-ISO 8062 CT9 to CT11.
When should I choose hand moulding instead?
For single pieces, short runs or castings heavier than 250 kg. See hand moulding.
