R & D Strength and Teamwork

The scientific research team is composed of researchers in materials science, material physics and chemistry, material processing, and long-term research and development, production technology, and enterprise management personnel of silicon carbide ceramics, with strong technical strength and professional knowledge structure.

In 1994, Dongxin Seal Co., Ltd. cooperated with the 704 Research Institute of the Seventh Academy of China State Shipbuilding Corporation, with investments of more than 500,000 yuan, and produced the largest diameter (Ф530mm) silicon carbide seal ring in the country at that time, successfully filling the domestic gap.

National Torch Program Project Certificate (Project Name: Large Diameter Silicon Carbide Seal Ring Number: 98D231D7000263)National Key New Product Certificate (Project Name: Large Diameter Silicon Carbide Seal Ring Number: 98G041D7000053)

Liquid Phase Sintered Integral Double-Arc Ballistic Insert Plate

The utility model is a large-size silicon carbide ceramic ballistic protection insert plate. The plate body is a whole piece of double-curved silicon carbide ceramic plate, fine and compact, with smoothly transitioned periphery. The arc surface radii of the inner and outer sides of the plate are equal;

Board size is:: 315mm×250mm×10mm

Weight is approximately:: 2.150kg

New Product Development

In addition to mechanical seal products, the company has developed the application research of silicon carbide ceramics in honeycomb ceramic carriers, ballistic armors and precision parts.Silicon carbide ceramic is one of the typical structural ceramic materials. It has the characteristics of high strength, high hardness, high temperature resistance, corrosion resistance and wear resistance, so it has a wide range of applications in the fields of national defense and military industry. The high hardness and high wear resistance of silicon carbide ceramics can be used to prepare ceramic tools, ceramic bearings, balistic armor, various valves, wear-resistant linings, and sealing ri

In addition to mechanical seal products, the company is carrying out research on the application of silicon carbide ceramics in honeycomb ceramic carriers, bulletproof armors, and precision parts.

With the development of the Chinese automobile industry, the annual domestic demand for honeycomb ceramic carriers alone is expected to increase at a rate of more than 15%.
