Fountain Foundry offers a variety of finishing services done both in house or with a variety of local and reputable partners.
After the casting runs through the shakeout to break it from the sand, it is time to go through the degating process. Degating is the removal of the heads, runners, gates and risers from the casting. Runners, gates & risers are removed using various methods including cutting torches, bandsaws, and cutoff blades.
Once all of the extra material is removed from the castings, the casting is then put through a blast cycle. Parts are loaded into a large tumble blast unit, where they are blasted with an S-460 steel shot that is propelled by 3600rpm blast wheels. The abrasive media strikes the castings surface at high velocity to dislodge the mold remnants like sand & slag from the casting surface.
After blasting, the casting will move to the finishing area. This step involves grinding & sanding the casting in order to achieve the desired dimensional accuracies, physical shape, and surface finish. Removing the remaining gate material, called the gate stub, is usually done using a grinder.
After going through the finishing process, castings are packaged for shipment or move on to additional processes. Fountain Foundry offers additional in house or sourced processes including but not limited to:
