  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.
