Greensand Mold Tutorial

GREENSAND PROCESS:

Patterns are made out of aluminum, wood, or plastic material. We have 3 cope and drag lines (Rollover) and 1 match plate line (Rota-Lift) with multiple flask sizes ranging from 16x78 to 33x78 (Rollover) and 20x28 to 18x40 (Rota-Lift). The green sand is a mixture of sand, clay mix & water to support a solid forming mold within minutes.

Green sand castings are produced with +/-.030 - .060" tolerances and a surface finish (150 / 350) that is a little rougher than the permanent mold process. Min. wall thickness required around .250".

Our niche at the greensand foundry is in the paint support business (Automotive Paint / Assembly). We can be competitive with larger castings (10 lbs. +) or low volume small castings. We do not have automatic machines to support high volume small castings but are happy to review for quote to see if project fits.
