【Amazing Technology without a Trick!】Leading-edge technologies of metal working such as photo-etching, etching + diffusion bonding, half-etching + through-etching

This is the state-of-the-art technology developed by OSAKA SMEs. At the MOBIO Tech Hall, you can discover amazing technologies! 


"Photo-etching" is a chemical precision processing technology that partially corrodes materials such as metals using the photo engraving process.

SGK introduced a large-scale automatic photo-etching line, which had been considered impossible and implemented mass production of long and fine products free of burrs and distortions. As the attached, the speaker frames at about 1300 mm length have been manufactured without burr, distortion, and narrow hole pitch.

It manufactures high-aspect-ratio products and products with complex cross-sectional shapes by stacking and diffusion bonding of multiple photo-etched metal plates. And appropriate combination of half-etching (etching only one side at arbitrary depth) and common shape-forming etching provides more freedom of design.
