In 2011, three ceramic and metal composite materials emerged at the same time. The three composite materials can be summarized by a keyword.
D-STAR Ceramos® Chronograph
EraCeramos is a new material created by combining titanium carbide and high-tech ceramics. It was first used in the manufacture of watches. The case and bracelet are treated with special surface hardening technology (Kolsterising).
Radar Ceramos® Titanium Carbide Cermet
Ceramos® titanium carbide cermet is made of high-tech ceramic materials and alloys. It has the same texture as high-tech ceramics. The difference is that it not only has a strong metallic luster, but also has thermal conductivity of metal. Fast temperature adjustment, unlike high-tech ceramics which are thermostatic materials.
EraCeramos®’s molding process must be performed in a very precise and demanding-high pressure environment equivalent to 1000 Pa. Next, the process part and the mold are placed in a vacuum high temperature environment at 1450 ° C to complete the sintering until the mold is chemically decomposed.
In this process, the craft object will shrink by 20% and reach the final size and hardness specifications.
The platinum case of the D-STAR Ceramos® watch is thrown out with a diamond diamond grinding wheel. The difficulty of the process is conceivable. It is in line with the saying ‘Don’t take the porcelain work without the diamond.’ . After careful polishing, the surface of Ceramos® watches presents a sparkling effect with unique sharp edges. After that, a golden yellow chemical vapor deposition (CVD) coating is formed on the surface of the case with titanium nitride (TiN) at a high temperature of about 1000 ° C, and then polished to give it a higher gloss.

钨 Tungsten Carbide Powder
ADORADO is the main raw material used in the manufacture of the first wear-resistant case. The powder is mixed with a synthetic bonding material and injected into a mold in a viscous melt state.

Injection-molded case
带有 After being taken out of the mold, it bears the Rado logo, which has anti-counterfeiting functions. The case at this time is still fragile and needs further processing

Finished case
At a temperature of about 1000 ° C, titanium nitride (TiN) is used to form a golden yellow chemical vapor deposition (CVD) coating on the surface of the watch case, and then it is polished to a very high gloss
