Production Molding & Core Making Processes
Precision Green Sand Molding
The benefits of precision green sand castings are numerous: low cost tooling, flexibility of modifying tooling or part geometry quickly, short lead times, prototype castings through high volume production quantities, thin and thick wall casting flexibility, exceptional “as cast” surface finish, intricate detail, complex coring and high integrity castings.
We use flasks (mold boxes) from very small (12"x16") to very large (4’x 20’ and 8’x 8’) to produce a wide range of precision green sand aluminum castings in the range of 1 ounce to 4,000 lbs. To support fast and quality precision green sand molding, we offer the following in our facilities:
- 3191 Osborn Rotolift molding machine, up to 32"x52" molds
- 3161 Osborn Rotolift molding machine, up to 26"x36" molds
- 4 Molding Stations using jolt squeeze molding machines, 12"x14" up to 16"x24" molds
- Floor molds capable of 8’x 8’ and 4’x 18’ sizes and 4,000 lbs. cast weight, built at Pentz.
Our high tech PLC-controlled sand mixing system, sand lab and skilled technicians set the standard for excellence in the foundry sand system control and have earned us a reputation for providing exceptional “as cast” surface finishes.
