3D ceramic fiber shapes can be molded using our in-house vacuum forming machines. This process lends itself to higher volume parts that need to be molded to net shape, thereby minimizing the need for any secondary machining operations. A tool room can design and fabricate molds, and different batches can be formulated to meet your requirements for temperature rating, density and hardness.
