Why choose us?
We have a professional advanced ceramic production plant with 15 years of professional experience and many technical research results in the production of advanced ceramics.
We only produce high-quality products, using the best raw materials and equipment. In the preparation of raw materials, we grind alumina to submicron particles, which ensures the performance of subsequent ceramics.
In the molding process, we use a variety of advanced equipment, such as injection molding machines, isostatic pressing machines (CIP), hot pressing machines, etc. These equipment and the operation of our professionals ensure the quality of alumina ceramic products.
Sintering is a very critical step in the ceramic manufacturing process. We use a rapid sintering furnace (RAPID) to ensure quality while greatly shortening the ceramic sintering cycle. We also have microwave sintering furnaces, hot isostatic pressing furnaces (HIP) and other equipment for the sintering of different alumina ceramics. Our professionals strictly and accurately control the ceramic sintering time and temperature to further improve the performance of alumina ceramics.
We conduct strict product inspections on our products. For high-precision ceramic parts, we achieve the smallest and most reasonable tolerances.
A group of R&D teams with rich professional knowledge are at your service at any time. We enjoy a good reputation at home and abroad and are appreciated by many partners.
We can provide you with
A variety of purity options: 95% and 99% alumina ceramics with various purities.
Customization service: Products of various specifications and sizes can be customized according to your drawings and requirements.
Free samples: Free sample testing is provided.
Package
Gorgeous carefully packages each product to prevent the goods from being damaged during transportation. We ensure that the goods delivered to you are of high quality and complete.
