Our process applies extremely high centrifugal forces ("G" force) to the molten metal throughout the critical solidification and thermal contraction phases. A minimum force of 60 times the force of gravity is applied to the metal. Our process also guarantees a seemingly infinite amount of pressurized riser material feeding the solidifying form. The "G" force produces a centrifugal separation of any impurities driving them to the bore allowing removal during machining.

The water cooled mold wall applies unidirectional chilling of the metal. This allows the material to undergo directional solidification imparting optimum strength for ring and cylindrical structures. The uniform directional advance of the solidification transformation also provides a cleansing effect as impurities float ahead of it toward the riser area of the bore.

The dynamic duo of directional solidification and high "G" force mold filling provided by our process guarantees the highest quality metal components. The low cost mold materials and process efficiency offer a cost effective solution to your metal component procurement needs.

POINTS TO REMEMBER

• Johnson Brass and Machine focuses on applications where the vertical centrifugal cast alternative is the most economical method to produce the required quality component.
• Our vertical centrifugal formings are usually produced with length to diameter ratios of less than 2:1.
• Our continuing investment in the latest Computer Numeric Control (CNC) machining equipment is complemented by our in house metallurgical lab, complete certified Non-destructive Test (NDT) testing capabilities, and improved foundry capacity.
• In commonly available copper based alloys (CDA 932 and 954), we offer our best value in the 14 inch and over size range. As the diameter increases our formings become even better values.
• Uncommon alloys, heat treatment, near-net shaping, Non-destructive Testing (NDT) or certification requirements allow us to save you cost on your centrifugal forming requirements (including those smaller than 14 inch diameter).
