Ceramco’s production formulations are developed to address the varied environmental extremes in which OEM ceramic components are commonly used. Although the properties of ceramics in general are well documented, many industrial applications push the envelope on specific requirements (in turn) leading to the development of new formulations to successfully address them.
Production formulations are also engineered as user defined, developed for an OEM ceramic component with a unique set of conditions it must satisfy. As technology advances across all industry, what was a unique set of challenges can become mainstream. Ceramco is ready with a formulation that is already proven and well documented.
The manufacturing process may also drive the need for a production formulation. Such is the case with the differing requirements of additive compared to injection molding. While both may require and utilize a ceramic formulation of almost 100% alumina, as is Ceramco’s A998, there are some differences. With that in mind, this chart of production formulations should always be considered as only a point of general reference. While the formulation that is “just right” for your OEM ceramic component’s requirements may not appear on this chart, it may be only a phone call or an email away from being available.
