  Features(Overview)                                                                                               

 

Stainless steel foil (coils/strips) made in Japan.
We can make strips as thin as 0.010mm (10μm),

with a guaranteed precision thickness of ±1~3μm.
All our stainless steel product grades are available,

for example, 301 ,304, 305 , 316, 316L, 430 ,420J2 , 631(17-7ph) and sus632J1(15-7PH).
We also can customize the thickness, width, surface finishing, hardness

and other specifications according to your needs. Please feel free to contact us.

 

  Main uses                                                                                                              

 

Dome switches for cell phone, shims for use in automobiles,

camera shutters, toner/doctor blades, etc.
*In addition, changing thickness for weight saving of the parts

or miniturization from the current product are also effective.

 

  The reason why you choose us                                                                             

 

1. Small quantity, short time delivery

If we have stocks, we can ship from a minimum of 1 kg sample in a few days.
We also manufacture custom-order materials in amounts of 300 kg and up

(Some materials are allowed 50 kg) in as few as 3 weeks.

 

2. High-precision thickness

We guarantee thickness tolerances that cannot be reproduced by competitors.
Example: 

            t <0.30mm     Tolerance ±1 - 3 μm guaranteed

            0.30 mm≤t     Tolerance ± 1% guaranteed

 

3. Ability to add multiple features

We are capable of adding a variety of features to metallic materials

(resin coating, plating, bonding different kinds of metal, multigage skiving, etc.).

 

4. Unique technology and custom-made solutions

We provide customed solutions to your problems with our unique

technologies and well versed knowledge of materials acquired through

our experience of manufacturing 50,000 items.

 

5. Choose the appropriate base metals for your needs

We carefully balance quality, delivery time and price,

procure various base metals from all over the world.

We manufacture appropriate products to your needs.

 

6. To control metal structure(chemical formation)

We can manufacture ultrafine metal structures with a grain size of 1 μm.
Using finer grain sizes provides benefits such as hardenability,

balancing strength and ductility, and precision press processing.

 

7. Lower total cost

We taking your processing into account,

offer you reduce a total cost by using our product.

 

8. Global network

Our plant located in Japan, Shanghai and Taiwan,

we also support flexibly local procurement and production transfer.

Manufacturing Processes	Outline
Base metal	We carefully balance quality, delivery time and price, procure various base matals from all over the world. We manufacture appropriate products to your needs.
Cold rolling	We have rolling machines like 18-high mills (Z-High type), 24-high mills (Sendzimir type), and 4-high mills, etc. We choose suitable rolling machine for each specification of metals. An AGC program in rolling machines controls pressure and position, enables an accuracy of ±1~3μm at thicknesses 0.20 mm or less, and ±1% at thickness greater than 0.30 mm in cold rolling process.
Annealing	We possess BA (Bright Annealing; Continuous-Type ), BELL(Bell-Type), and TA (Tension Annealing; Continuous-Type ) furnaces. Annealing for internal stress removal is also possible as well as soft annealing. Moreover, according to our accumulated experience and know-how, we can control the size of metallographic structure (carbide grain size).
Surface inspection (CCD)	All-digital processing by CCD camera detect surface defects. This high precise inspection machine detects even the minute scratches on a flat surface.
Slitting	Saitama plant has 7 different type of slitting machines, so we use the appropriate machinery for your metals and specifications. We can guarantee high quality slitting, like width tolerance and burr by setting optimum conditions for each metal's specification.
Sample inspection	We have furnished all the measuring equipments for mesuring metal properties and specifications, such as hardness and tension, etc. We also possess SEM (Scanning Electron Microscopes ) with EDX function. Furthermore, we have FE-SEM (+EBSD+EDS) which is more precise than SEM, so we can analyze micro crystal structure, too.
Packing	In order to prevent damage, rust, or other flaws arising in our products under transit, we alter our package one by one. We also accept specific packaging requests from you.
