- About Production Techniques
- by Akiyama Co., Ltd. CEO Yutaro Akiyama
Akiyama Co., Ltd is one of the jewellery factories producing earrings,
bracelets and pendants, based in Yamanashi, Japan, established in 1948.
This case is made mainly using casting techniques.
So far, it is difficult to manufacture large and flat shaped items
with exactly fixed sizes such as iPhone cases
because the materials tend to shrink during the casting process.
We usually use fire for welding,
however, the flat surface of materials easily loses its sheen if do so.
So we had to find an innovative method with our skilled workers.
After trial and error,
we finally came up with brand new casting method without using fire.
In addition to that, there were many other problems,
such as smoothening rough surface caused from the casting process,
control the exact shape to fit iPhone, etc.
but we could get over with our knowledge and techniques.
We hope you can feel our effort and passion,
not only the design and techniques.
