Our Advantage

Special ceramics have a series of advantages such as wear resistance, heat resistance, corrosion resistance and so on. Used in a variety of places of industrial production. With the development of technology, many aspects such as the heat resistance and hardness of ceramics are further optimized.
Mingrui has its own technology to meet customer requirements for hardness, heat resistance, smoothness.Mingrui  has the most professional technology.


The ceramic electronic components: low loss at high frequency. Good insulating , high strength, , low dielectric constant, Great mechanical strength, high air tightness, high chemical stability, etc. We can produce all kinds of ceramic holders, ceramic support, ceramic tubes, ceramic pipe, ceramic ring, etc. Widely used in electronic components, electronic device and electric products. Our products meet the international standards.
