Shop Spotlight: Rache Corporation
Rache Corp. is a laser specialist, fabricating, welding, marking, and cutting with its laser expertise to produce ISO 9001: 2015-compliant, tight-tolerance, high-yield, quick-turnaround parts for the medical, electronics, military, automotive, and aerospace industries.
These parts are production- and prototype-quality, without the use of toxic chemicals, typically delivered within 48 hours. The quality management system (QMS) will be AS9100 third-party certified by the fourth quarter of 2019.
Rache’s expertise in precision thin material fabrication extends into a range of plastics and metals, including exotic and high-temperature alloys, such as Kovar, nitinol, Inconel, Monel, steel, titanium and others with no edge factor, roll off, or edge deformation. In addition to dozens of other materials, Rache is willing to test new materials in an engineering trial.
With a thickness range of 0.0005 to 0.090 inches, laser cutting is an alternative to EDM, die-stamping, and chemical etching.
Tolerances include inside corner radii held to within 0.001-inch, holes down to 0.002-inch in diameter, and dimensional tolerances of plus or minus 0.001-inch.
Rache Corp. has manufactured aerospace components, microwave stripline, apertures, circular springs, copper circuits, custom screen and mesh, shims, antennas, EMI shields, gaskets, ID tags, masks, and metal diaphragms.
Services include laser cutting, laser welding, laser marking, laser drilling, laser stitching and hand forming, prototyping, helium leak testing, and deep laser engraving. For details about Rache's capabilities, visit this page.
Rache argues that deep laser engraving has advantages over alternative technologies, including machining or chemical-etching. Those are quicker setup and processing for either prototypes or production quantities, the ability to meet complex geometries and tight radius. Small overall spot size creates higher resolution in hard to reach areas.
Its laser welding process offers very low heat input, a bead size from 0.005-inch to 0.030-inch with a weld penetration of 0.065-inch and joining materials as thin as 0.002-inch.
