Casting Sizes
Dotson produces castings ranging from 2 to 50 pounds that fit into a 17″ x 21″ x 10″ box.
Cores
Cores are produced in house, just in time, using chemically bonded, automatic, cold box machines.
Custom Casting Molds
Molds are made on 20″ x 24″ horizontally parted, green sand, automatic molding machines.
Finishing
The finishing steps have been automated into a continuous flow process. Hydraulic wedges are used to remove gating from the castings then the castings remain on continuous conveyors through inspection. CNC automated grinding machines, a trim press, or robotic grinding cell are then used to finish 100% of all castings through some form of automation.
Machining
At Dotson, it’s our vision to become the world’s most agile foundry, which means the machine shop must operate under the same key guiding principles that drive our agility in the foundry. We use only the highest quality mills and lathes in order to ensure the production of a quality product and eliminate issues for our customers.
Lead times are kept low because the machine shop is located in the production flow of the foundry where castings are machined in-line just a few feet from the finishing department.
