Synthetic diamonds are manufactured, diamond-like crystals.The manufacturing processes work to duplicate the pressure and temperature of the natural diamond-producing environment. The formation process is initiated by forcing a chemical reaction, through adding a catalyst to carbon, and placing the mixture in high-pressure cells. Then, the mixture is cooled and washed with acid, which results in a synthetic diamond.

HPHT synthetic diamond products are produced by high pressure high temperature (HPHT). Synthetic diamond mono plate is cut from good HPHT crystal diamond; its grades are divided into D21, D22, D23; The product range offers a wide choice of geometries, edge lengths and cross-sectional areas to give the synthetic diamond tool and die maker unprecedented options and the opportunity to manufacture tools for a broad range of applications.

 Lab Grown Diamonds are grown in highly-controlled laboratory conditions that simulate the earth’s natural growing environment, producing real diamonds that are optically, physically and chemically identical to earth mined diamonds, so its refractive  index , density , hardness , dispersion and crystalline structure are almost same as each other. Nowadays almost no jeweler, diamond merchant or even a customer with microscope can tell one apart from the other.

Yinwang Diamond Wire Drawing Die Blanks are Polycrystalline Diamond (PCD) products made under ultra-high temperature and ultra-high pressure, during which process diamond powders are sintered together with strong grain-to-grain bonding under the functioning of a few metal catalysts containing Cobalt. These PCD products not only have high wear resistance, hardness and good thermal conductivity, but also possess high mechanical strength and tenacity. They are suitable for high-speed drawing of nonferrous wires such as bronze, aluminum, nickel and that of stainless steel and other alloy wires.

Yinwang drawing dies are famous for the high quality and reliability. To meet all kinds of market requirements, Yinwang offers a large selection of dies for drawing wire and rod, which range from ultra-fine wires to intermediate wires and rod size wires.

Chemical vapour deposited (CVD) synthetic diamond is typically produced in a cacuum system below atmospheric pressure, with the carbon atoms supplied from a gas such as methane. The ability to control gas purity makes CVD diamond growth a particularly effective way to make synthetic diamond for applications requiring very high chemical purity, including optical electronic and certain mechanical application
