A World-Leading
Lab-Grown Diamond Provider
About ZS-Tech
With intensive efforts in microwave plasma-assisted chemical vapor deposition (MPCVD) technique, Shanghai Zhengshi Technology Co., Ltd. (ZS-Tech) boasts the world-leading capabilities of research, development and production of lab-grown diamonds. Our CVD (chemical vapor deposition) diamonds feature high grades of clarity and color, larger carat weights, and purely natural growth, Without any treatment. Our products are widely applied to jewelry making as well as scientific and technological fields, such as industrial cooling, semiconductors, high-end electronics, auto driving, among others.
An Era of Z Diamond
Pure CVD diamonds
highly graded clarity and color
ZS-Tech is one of the few companies that can produce high-quality CVD diamonds without any color treatment all over the world.
Applications of the CVD diamonds
Automobiles and Aerospace
Quality and Efficiency
New technologies and machining solutions are changing the way of vehicles and aircraft manufacturing. ZS-Tech can provide ultrahard materials that reform the machining ways of the automotive and aerospace industries. Our uniquely designed solutions and extensive know-how for applications will help handle your machining challenges.
Thermal Management
CVD synthetic diamonds achieve higher power density.
ZS-Tech’s CVD diamond radiators can offer higher levels of thermal performance, system performance, stability and equipment life than common ones. They can run at higher power levels without increasing the working junction temperature (Tj).
Anti-wear Parts
An anti-wear solution expert
We can successfully lengthen the service life of your tools and machines, and apparently, reduce the operating cost with improved safety.
Optics
Optical-quality CVD Monocrystal Diamonds
Optical-quality CVD monocrystal diamond is new functional material. Diamonds have a broad prospect of applications in optics because they have many excellent characteristics: high hardness (non-abrasive optical lens), high transmittance in a long-wavelength infrared light band (at room temperature), highest thermal conductivity at room temperature, superior chemical stability, and high resistance against thermal shock. The optical-quality CVD monocrystal diamonds can be widely used in aviation, military, scientific research equipment and other aspects, including CO2 laser windows (10.6 microns), high power microwave windows, among others. They function as advanced products with high added values.
