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 #1: Precision parts machining~Cutting edge / swaging edge ~
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
Products #2: Precision stamping/ blankingCapable to stamp out the thin plate, small pieces, precision parts and materials difficult to stamp
Progressive stamping die
Products #2: Precision stamping~Die design~
Composite swaged parts
Brush of micromotor
Composite swaged parts in the die make the cost reducedInvestigating 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.
〔Laminated parts of motor core 〕Stamp out motor cores and lay ten or so cores, and make them staked at once in
the progressive die
〔Composite parts of miniature vibrating motor and brush 〕Stamp out a brush and stake it with other parts in the progressive die Contact point (thickness: 0.04 mm)
Holder parts (thickness: 0.15 mm)
〔Minute electronic parts 〕Stamp out the parts in complicated form with high precision, high quality &
low cost. You can see how small a parts is as compared with a lead of mechanical pencil
〔Exterior components of stationary 〕Supply fine parts (no scratch, no dent nor burr) stably
Manufacture the parts in a 3‐D form that is high level of difficulty
〔Extremely thin metal parts thickness: minimum 0.005 mm〕
Thickness & Width : 0.08 mm, 80 mm Slit width & length: 0.2 mm & 65 mmStamp with minimum burrs & warp
Products #2: Precision stamping parts
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
