Henan Sifangda Superhard Materials Co., Ltd. Announcement on Obtaining Patent Certificate

The company and all members of the board of directors guarantee that the content of the information disclosure is true, accurate and complete, and there are no false records, misleading statements or major omissions.
Henan Sifangda Superhard Materials Co., Ltd. (hereinafter referred to as “Company” and “Sifangda”) newly obtained two utility model patent certificates issued by the State Intellectual Property Office. Details are as follows:

1. Polycrystalline diamond composite sheet is an excellent cutting tool and wear-resistant tool material. It has high strength and high wear resistance. It is widely used in many fields such as oil and gas, coal, geological drilling and so on. A high impact polycrystalline diamond composite sheet can improve the bonding area of ​​the diamond layer and the alloy matrix in the composite sheet by reducing the interface shape of the diamond layer and the cemented carbide, reduce the stress at the edge joint, and improve the resistance of the composite sheet. Impact toughness.
2. A new type of super-hard material roller bit is a new type of super-hard material roller bit suitable for rotary drilling rig. The tooth head and the gauge surface are made of super-hard material teeth and gauge flat teeth. The service life is dozens of times that of the cemented carbide roller bit, and the rock drilling efficiency is significantly improved, especially in the application of hard rock, and the effect is remarkable.
The above patents have been applied in the production of the company's products. The acquisition of patents will not have a major impact on the company's production and operation, but it will help protect the company's intellectual property rights, form a continuous innovation mechanism, and enhance the company's core competitiveness.
