The plate frame is produced in 
a six step process.

1. The molten iron (2530-2570F)  is poured into the assembled sand mold and allowed to cool for 2-3 hours.

2. After cooling, the casting is removed from the sand mold by "shaking out" the sand.

3.  The riser is wedged off the casting.

4. The casting is Wheelabrator shot-basted to remove residual sand on the surface.

5.  Flash lines and the riser stub are ground off.

6.  The casting is finished painted, prior to machining.
