No-Bake Process
Flowserve Dayton Foundry's No-Bake Process can satisfy the most demanding requirements for high-quality, high-performance castings.
Utilizing wood, plastic, styrofoam® and metal patterns, no-bake is particularly appropriate for prototype work as alterations can be made cost effectively. It is also appropriate for one-offs, as well as high production runs.
