Molding process

Qualified people doing quality work

No-Bake Sand Molding

In the no-bake process, sand is mixed with a chemical binder/catalyst system and then molded around the cope and drag halves of the pattern. After a specified period, the sand mixture hardens to form the mold halves and the pattern is drawn. Then, a refractory coating may be applied to both mold halves before they are brought together to form one complete 
mold for pouring.

Flask & Pit Molding

A flask is a metal frame used for making and holding a sand mold. For larger jobs, a pit instead of flasks is used. There are many sizes of flasks and pits. The size needed is determined by the pattern and amount of sand needed.
