Sand Casting
Green Sand
The “Green” sand process uses only sand, water and clay to make the mould. Wet sand medium is compacted around the pattern with a jolting action. The compacted sand forms both physical and chemical bonds to retain the pattern shape. The sand costs are lower than other moulding processes making green sand an economical casting method.
For competitive production of green sand castings, a modern semi-automatic molding facility is used (International Jolt-Squeeze). Cope and drag (top and bottom) halves of the mold can be made and closed in minutes, permitting castings to be poured in the same shift.
No-Bake Sand
Kubota has both boxless and flask molding using no-bake sand technology. These molding areas give the most versatility, being able to make castings from less than 1 lb to over 4000 lbs.
