Here is an example of a restoration project. These solid brass Archimedean screws were removed from a food processing machine. They had been in use for a prolonged period of time and were coated with a thick layer of deposits.
The screws received our 2 stage blasting process finishing with a fine glass bead. The cost of this clean up procedure was far less than the cost to replace the items, and returned the screws back to their original efficiency.
