Company information
We will propose various precision jigs tailored to the work shape, utilizing ultra-precision machining technology developed with a vice, from the design stage. Are you having trouble with film burrs or deformation? Our ultra-precision finished "film cutting molds and jigs" have no burrs or deformation, are long-lasting, and can handle foils (0.005 mm and above) that are typically considered difficult. Thanks to our know-how regarding blade shapes, materials, and other factors, we can also create structures that are difficult for various adhesives to adhere to.
