Size:
Dotson produces castings ranging from less than a pound to 50 pounds which can fit in a 20" x 24" mold
Cores:
Cores are produced in house, just in time, using chemically bonded, automatic, cold box machines
Molds:
Molding is done on 20" x 24" horizontally parted, green sand, automatic molding machines
Finishing:
The finishing steps have been automated into a continuous flow process using hydraulic wedges for degating. Parts remain on continuous conveyors through inspection and on to CNC controlled automatic grinding machines. Most parts are under 4 hours from the start of the molding process through to finished goods.
