Metal investment casting

From seven days to seven hours – Cyclone, the new extremely fast technology for the production of investment casting shells

During the metal casting process, the ceramic shell is built around a wax pattern by several layers of so-called slurry and fire proof sand.

Under the conventional process, every layer needs to dry for approximately 24 hours before the next layer can be applied. Therefore, a shell build requiring seven layers can take up to one week to construct.

MK Technology developed a high-speed drying process for Rapid Prototyping, thus reducing the production time of a shell to a few hours.

As the investment casting industry also showed great interest in this process, the high-speed drying technology was adapted to the requirements of serial production. So called continuous drying systems were developed: Booster and Tunnel.
