Three kinds of PrecisionPrecision products and PartsParts services based on ProductProduct #1#1 our core technology of precise grinding DesignDesign && ManufacManufacttureure ofof ModularModular DiesDies ProductsProducts #3#3 Products #1: Precision parts machining ～Cutting edge / edge ～

NOGAMI has acquired the (technical) know‐how about material selection, heat treatment, shape of cutting‐edge and surface treatment through 41‐ year’s experience. Know‐how of keeping the quality and precision solves the problems of early wear and breakage. Products #2: Precision stamping/ blanking Capable to stamp out the thin plate, small pieces, precision parts and materials difficult to stamp By using the technology achieving ultra‐precision perpendicular and parallelism tolerance, it is capable to stamp out the materials which seems tough to punch; such as thin plate, small pieces, precision parts and materials difficult to stamp

Progressive stamping die Products #2: Precision stamping ～Die design ～ Composite swaged parts in the die make the cost reduced Investigating the technologies of die design over 20 years and acquire the know‐how. A parts which consists of 2 components was formerly welded manually, and is swaged in the progressive die. It makes the quality of parts stable and the cost reduced.

Composite swaged parts

Brush of micromotor Products #2: Precision stamping parts

〔Extremely thin parts thickness: 〔Composite parts of miniature vibrating motor and brush 〕 〔Laminated parts of motor core 〕 minimum 0.005 mm〕 Stamp out motor cores and lay ten or so Stamp out a brush and stake it with other parts in the Thickness & Width : 0.08 mm, 80 mm cores, and make them staked at once in progressive die Contact point (thickness: 0.04 mm) Slit width & length: 0.2 mm & 65 mm the progressive die Holder parts (thickness: 0.15 mm) Stamp with minimum burrs & warp

〔Exterior components of stationary 〕 〔Minute electronic parts 〕 Supply fine parts (no scratch, no dent nor burr) stably Stamp out the parts in complicated form with high precision, high quality & Manufacture the parts in a 3‐D form that is high level of difficulty low cost. You can see how small a parts is as compared with a lead of mechanical pencil Products #3: Precision Stamping Dies and Jigs ～ Design & Manufacturing ～ Stamping a thin material as thin as 0.005 mm with ● Prevent contamination and minimize sticking Al on the die. ● Minimize burrs and deformation, and keep the fine section long time ≪Aluminum foil ≫ ≪TCP Film≫ ≪Electrode of Li-ion battery≫ Thickness 0.015 mm 0.12 mm 0.12 mm
