Our factory
Jinzhou Yunxing Industrial Ceramics Co., Ltd. was established in 2000, mainly producing various types of tubular ceramic products and various industrial parts with alumina content above 99.3%. The factory covers an area of 4000 square meters.
The company's main products are: alumina ceramic tubes, alumina ceramic crucibles, alumina ceramic rods, alumina ceramic boats, alumina ceramic plates, alumina ceramic parts, etc.
The company currently has 3 1800 ° C high-temperature furnaces and 2 1400 ° C low-temperature kilns independently designed and manufactured. The molding process is mainly based on grouting molding, and has other molding process equipment such as extrusion and hot die casting.
The company has 105 employees, including one senior ceramic engineer, three engineers, six overseas sales staff, and four professional after-sales staff.
FAQ
Q1. How to quickly obtain a quote.
A1. Provide detailed dimensions and quantities of the products you require. What is the purpose of the product. Customization of drawings can also be provided.
Q2. What are the benefits of alumina ceramics?
A2. Alumina ceramics is a widely used material because it can be produced in a range of purities—from 85 to 99.9 percent pure—that provide unique benefits. Generally, alumina ceramic components offer quality strength, hardness, corrosion resistance, and thermal stability.
A3. Alumina is often used as a replacement for metallic components in demanding engineering applications. IPS Ceramics supply 95% alumina for applications below 1450 ºC / 2650 °F and 99% alumina for temperatures up to 1600 ºC / 2900 °F or where contamination of the sample must be avoided.
A4. Alumina shares several characteristics with other polycrystalline ceramic materials, such as moderate tensile and bending resistance and the brittle fracture behavior, which is the main disadvantage of the mechanical properties of alumina.
