OPTICAST, our high-performance ceramic media for slurry and stucco, is engineered for the unique demands of the investment casting industry. Unlike mined alternatives, OPTICAST is manufactured, delivering consistent quality, predictable costs, and enhanced supply stability. OPTICAST combines exceptional thermal stability, low expansion, and high permeability to deliver superior precision and fewer defects—making it ideal for complex, high-temperature pours. Beyond its advantages, OPTICAST is an economical choice, offering lower cost than zircon while maintaining consistent quality and performance. Chemically inert and non-hazardous, OPTICAST reduces environmental and safety concerns and supports efficient, high-throughput production across a range of applications.
