CVD Diamond

The main products of MoreSuperHard comapny include CVD diamond film, wire drawing core, dresser blank, forming knife blank, welding tool blank, geological bit blank, thermodynamic grade CVD diamond, optical grade CVD diamond and so on. Regarding the market situation of the company in the first half of this year, my boss said that the overall performance of the market in the first half of the year has slowed down compared with last year. The main reason is that the downstream market is affected by environmental factors, but the market has continued to grow. In addition, the customer's requirements for the processing accuracy of the material itself are getting higher and higher, especially the thin diamond film of 0.2 mm and 0.3 mm, the required tolerance is relatively small, and the precision of the tool to be processed is better.

In the past two years, the rising cost of raw materials has brought pressure to all walks of life. Under this situation, we always adhere to the service as the foundation, innovation as the soul, and constantly optimize the production process and research and develop new products according to market development and customer needs. At the same time, we are making active and effective efforts on the road to reducing costs for our customers.

For the future development of the company, the market and customer demand are fundamental. The next step is to further improve the wear resistance and electrical conductivity of the product. In addition, we hope to make breakthroughs in the tool market, and the tool market is relatively large. Customers often ask about tooling problems, and their application fields are more and more extensive. This is a potential development direction. In functional applications, electronic devices, heat sinks, and substrate materials are more bulky, but users usually require products. The price is lower. At the same time, they have higher requirements on the processing yield and efficiency of the products. At present, it is more difficult to reduce the cost. This is a bottleneck and a problem we will solve in the future.

MORE® CVD diamond introduction

1 CVD diamond dressing blanks

The finishing blank is divided into three grades: standard grade (CVDS) medium grade (CVDM) and high grade (CVDF)

A. CVD diamond dresser logs: diamond pen, dresser, dressing roller application

The CVD diamond dressing tool has high impact resistance and wear ratio. The wear ratio of different grades of blanks is between 20 and 1.8 million, and the performance is stable. It is suitable for multi-point dresser and dressing roller. It is sharpened by the CVD diamond dresser and has high surface finish and is suitable for large-scale industrial production.

B. CVD diamond forming tool blank 

The forming knife blank produced by MORE has good light transmittance, no crack, no breakage, good wear resistance and impact resistance, and the polished grinding wheel has high smoothness and stable product size.

2 CVD diamond tool blank

The CVD diamond tool blank produced by MORE belongs to the multi-crystal structure. It has no soft and hard surface. It is suitable for making welding tools. It has good wear resistance, high processing precision and good smoothness. It is suitable for processing high silicon aluminum alloy and composite materials. , graphite, ceramics and non-ferrous materials.

3 CVD diamond wire drawing core blank

CVD diamond wire drawing core has high hardness, good wear resistance, low friction coefficient and high surface finish. It is suitable for drawing stainless steel wire, tungsten wire, molybdenum wire, copper wire and aluminum wire. Since CVD diamond does not contain any binder, CVD diamond wire drawing die exhibits higher wear resistance, corrosion resistance, thermal conductivity, and thermal stability than PCD. Moreover, the CVD diamond is not electrically conductive, and the advantages of making a wire core are outstanding.

4 thermal grade diamond diaphragm

The heat dissipation performance of diamond is the best among the materials known in nature. In addition, the insulation performance is good, making CVD diamond an ideal material for electronic heat sinks. It is used to make heat sinks for high-power semiconductor devices, microwave devices and large-scale integrated circuits. . The CVD diamond heat sink sheet produced by Baolixin has a thermal conductivity of 1200~2000W/k.m and can be processed on one side or double side.

5 optical grade diamond diaphragm

High quality CVD diamond has excellent optical properties. From the X-ray, ultraviolet, visible, infrared, to millimeter microwave bands, there is a high transmittance.

6 Application of CVD diamond in geological drill bits

The microstructure of CVD diamond belongs to polycrystal, which is not easy to be broken compared with natural diamond, and has excellent impact resistance. CVD diamond component has only carbon element, no metal, and wear resistance is several times that of PCD diamond. Therefore, the use of CVD diamond to improve bit life has significant advantages.
