Ideal for prototypes or shapes simply not possible with Pressed or Extruded forming techniques. We isostatically press large shapes (blocks up to 12″ across and 30″ long or rounds up to 10″ diameter and 12″ long) that can then be machined. Conventionally Pressed and Extruded shapes can also be further machined. We have extensive capabilities for the machining of cores with over 100 machines available. We can also machine customer supplied material (see Capabilities).
