Net-Shape centrifugal technology provides measurable benefits compared to fabrications, forged parts, or conventional castings.
Near-Net Shaped Centrifugals combine the cost advantages of a product that has desired profiles. These are cast in with the metallurgical and thru-wall structural integrity that only the centrifugal process delivers.
Net-shaping can be readily added to centrifugally cast components through the use of sand or ceramic split dies. True net-shaping at investment casting levels of O.D. detail can be added by employing MetalTek’s proprietary net-shaping technology and special tooling. Either net-shaping or near-net shaping can vary dramatically and reduce post-processing costs while delivering the advantages of centrifugal casting.
Why use Net-Shaping as an alternative to fabrications:
Simplify: Reduces the number of components
Cost savings: Eliminates welding
Cost savings: Eliminates post-weld heat treat
Quality: Improves quality of difficult to weld material
Speed: Increases speed of production
Why use Net-Shaping as an alternative to forged parts:
Cost reduction: Reduces milling
Quality: Improved dimensional stability of a centrifugal casting
Speed: Shorter lead times / Increased speed of production
Design choices: Increased variety of alloy choices
Why use Net-Shaping as an alternative to metal casting or sand casting:
Shaping: Benefit of a static sand casting while eliminating mid-wall shrink
Welding: Smaller grain size compared to static sand casting improves weldability
Tooling: Mid-range tooling and casting pricing provides value for mid-short runs
Cost Savings: It reduces the amount of liquid metal to be poured, heat-treated and machined away
