Tighter Tolerance EDMs Pay Off for Medical Manufacturer: World Class Technology is more than the company's name, it is its reputation. Maintaining that rep meant finding machines to match the company title

摘要

While it never pays to be sloppy, manufacturing medical products sometimes calls for tighter tolerances than other production. For World Class Technology, McMinnville, OR, holding tolerances in the ten-thousandths-inch range was critical, and it was having trouble. With the machining equipment it had on-hand, WCT had difficulty holding the 0.0001" to 0.0002" tolerances it needed. The company specializes in metal injection molding of orthodontic products such as brackets, buccal tubes, and lingual buttons. Adding to the close-tolerance demands, the company must use a special nickel-free stainless steel to prevent nickel-related allergic reactions that can appear after two years of exposure in an orthodontic patient's mouth.
