SAND CASTING TOLERANCES
On the following pages is a discussion of common tolerance
issues related to sand casting. These standards are excerpted directly from the
Aluminum Association's handbook titled Standards for Aluminum Sand and Permanent
Mold Castings with the permission of the Aluminum Association. We are grateful
for their help.
Bear in mind that these are general industry standards and
many foundries, including St. Paul Brass and Aluminum
Foundry, are capable of better. Consult your foundry for more specifics.
Also remember that the if you get too fussy the cost may go
up.
