Laser Cutting

Over 25 years ago, we developed a process to laser cut thin metals that has become the industry standard today. Metals such as Kovar®, nitinol, Inconel®, Monel®, brass, copper, aluminum, stainless steel, titanium and many exotic and high temperature alloys can be cut exhibiting no edge factor, roll off, or edge deformation. Thicknesses range from 0.0005 to 0.090 inches. Laser cutting is an excellent alternative to chemical-etching, die-stamping or EDM.
Depending on the material, inside corner radii can be held to .001 inches, Hole sizes down to .002 inches in diameter can be drilled and dimensional tolerances of ± .001 of an inch can be held.
Our laser "stitching" allows parts to be "finger-formed" to reduce labor costs during production.
