Jinghui Ceramic has focused on industrial ceramics for 15 years. We have mature production technology, lower scrap rate and cheaper prices. We have one-stop services for molding, sintering, and precision machining. No outsourced assistance is required, and the delivery time is shorter and more controllable. We attach great importance to customers' experience, provide customers with timely and reliable after-sales service, and solve problems encountered by customers during the use of products.
In the production of zirconia ceramic shaft rod, the materials we use are mainly Y-TZP (Y2O3 Stabilized Zirconia) and Mg-PSZ (MgO Stabilized Zirconia). They have many characteristics such as high strength, high temperature stability, good chemical stability and good optical properties, so they have a wide range of applications and provide high-quality material options for manufacturing, biomedicine, aerospace and other industries. At the same time, with our precision machining production capabilities, we are able to provide different levels of precision zirconia ceramic parts to meet customers' high-precision assembly needs.
