Wire EDM Reduces Machining Time and Increases Accuracy

From Mitsubishi EDM/Laser

World Class Technology knows a little something about tight tolerances. The company specializes in metal injection molding of orthodontic products, including brackets, buccal tubes and lingual buttons.

Based on the west coast, this manufacturer maintains a cleanroomtype manufacturing environment. They use a special nickel-free stainless steel to prevent nickel-related allergic reactions from cropping up after two years of exposure in an orthodontic patient's mouth.

A few months ago, World Class Technology was having trouble holding the 0.0001-0.0002-inch tolerances they needed with their old machining equipment. So, when Tooling Supervisor John Ashton went searching for an alternative, he went to a source he had come to trust over the past 10 years-Mitsubishi EDM.

The company recently installed a new FA10S wire EDM unit, followed just weeks later by an EA12V sinker machine. Ashton says World Class Technology is also considering adding a FA10PS machine in the near future. While the company uses the FA10S for cutting ejector pin holes, core pin holes, gib pockets and other tooling, it uses the EA12V to create molds for its metal injection molding operation.
