Capabilities
No-Bake resin bonded sand molding, induction melting and 3D CAD engineering for complete heavy industrial casting production
Molding
- Phenolic Urethane No Bake (PUNB) cope and drag molding. 600 lb./min. continuous mixer. Mechanized roll over and draw.
Electric Induction Melting
- 700kw induction melting with two 2,000 lb. tilt pour furnaces. Maximum melt per day is 8,000 lbs
- Ductile iron treatment and pouring up to 600 lbs. per ladle
- Gray iron pouring up to 800 lbs. per ladle
CNC Pattern Making
- 3D CAD/CAM and CNC milling patterns and core boxes
- 3D CAD with Solidworks
- CNC toolpath with FeatureCAM
Hard No-Bake Molds and 3D CAD Tooling for Complex Castings
No-Bake molding with resin bonded sand is the most flexible and reliable sand process for complex castings. Hard resin bonded sand molds are made with the least expensive tooling or any legacy foundry tooling with minimal re-rigging costs.
