Dry Sand Precision Molding & Cores
Dry Sand molding is versatile enables molds to be made in multiple directions of mold sections and cores.
We utilize the dry sand molding process to build molds, when radical geometry, like deep pockets, thin ribs or size makes it impractical to green sand mold.
Innovative engineered hybrid molding methods by combining processes of dry sand, green sand, 3D printed sections build castings with unlimited geometry and size.
Dry sand molds and cores are finished and coated to create great as cast finish.
Our precision dry sand, casting tooling is typically CNC machined aluminum, plastic, wood, or a hybrid mix built with customer / Pentz approved CAD models. Tooling cost is relatively low depending on geometry and life is dependent on materials used with little tool maintenance.

Features of Precision Dry Sand Molding
| Process | Benefits | Typical Part Size | Typical Surface Finish (RMS) | Min. Draft Req. | Typical Linear Tolerances (as cast) | Typical Tooling Cost | Typical Volume |
| Precision Dry Sand Molding (AKA – No Bake, Airset, Cold Box CO2, etc.) |
Excellent for producing parts that require high strength and pressure tight/vacuum tight sealing characteristics. Utilizes chemically bonded dry sand to form molds used to cast parts. |
