Processing Lineup

Total support for complex electronic parts machining to keep pace with the evolution of today’s most advanced IoT devices!

Our complex machining technology for punching, bending, drawing, crushing, and swaging allows us to perfectly meet the advanced specifications required by our customers.
We give shape to high-level requests not only through individual machining technologies but by combining them into composite precision press machining. We offer customers the full package with everything from press machining to washing, metal-plating, and inspection.

Technologies and service process

1Precision Press Machining

We accommodate our customers’ needs not with one single technology but through all kinds of machining technologies, including precision punching, bending, drawing, crushing, and swaging.
We also offer high-productivity manufacturing using a super-high-speed press that operates at up to 1,600 spm.

2Barrel Finishing

Press machining always produces burrs. We have our own machining equipment and can remove burrs at the customer’s request. This process can handle board thicknesses of 0.03 to 3.3t.
Additionally, we can machine almost any material, including copper and nickel alloys and stainless steel.
We can handle specifications not only for burr removal but also for heavy cutting, medium cutting, light cutting, and more.

3Metal-Plating

Unlike most press-based manufacturers, we have our own metal-plating line (specifically for lids).
We have extensive knowledge about surface treatment techniques from our many years of experience.

Board thickness: 0.05-0.2t Size: 1.0 x 0.8–19 x 6.5 Materials: Fe-Ni-Co alloys, 42 alloys Plating specifications: electro Ni, electro-less Ni

4Tape-and-Reel Packaging

We do tape-and-reel packaging and tube packaging inside our class 10,000 cleanroom.

5Appearance Inspection

We do a lot of business with automobile-related manufacturers, and we strive to continually improve the quality of our products, particularly where dust is concerned.
We have a cleanroom at our company where we conduct appearance inspection and measuring tasks in a low-dust environment.
Some of our product appearance inspection operations are handled through automation.

Leave everything to us,
from precision press machining to surface processing,
packaging, and appearance inspections!

We can handle not only precision press machining but also barrel finishing, washing (single unit / line), metal-plating (electro Ni / electro-less Ni), packaging (tape-and-reel / tube / bulk packing), and appearance inspection (visual / fully automatic).
This gives us a major advantage in terms of both quality control and production costs.

We are fully equipped with automatic measurement systems, including image dimension measurement systems and a 3D measurement system. Tape-and-reel packaging and measuring are carried out in our cleanroom (class 10,000).
