Edo kiriko is traditional glasswork with detailed etching
and engraving on the glass surface using metal plates
and grindstones. Kiriko has a double-layered structure
of transparent and colored glass. After drawing rough
lines for the design with“sumitsuke”, the glass is
etched at once. “Rough etching” etches basic lines
and surfaces, followed by “san-ban kake”, “ishi kake”
and “polishing” to improve precision. The technique
called “etching” is a basic technique that is essential
for metallic mold production. Engineers design metal
molds based on CAD plans. By hearing the sound and
feeling the resistance, they move the
polishing machines little by little.

-Everything is for the production of beautiful parts.

Higher advancement and precision over previous technology is demanded in
metallic molds that make up new products and engineers are immersing
themselves in the process of trial and error. TPS has set a strict standard of
"surface precision of precision polishers being smaller than 0.2 microns" and
conducts nano-level management on precision processes such as polishing and
electric discharge. The most cutting-edge metallic molds are produced from the
latest processing technologies and the unshakable philosophy of experienced
engineers.
