New AFS White Paper Details 6 Parameters for Cost-Effective Metal Casting Design
“The geometric freedom of the metalcasting process allows multiple parts assembled together to become a single cast component, enhancing the finished component’s material and mechanical properties and ultimately the end product’s effectiveness and productivity,” said
The six parameters are:
1. Fluid Life 2. Solidification Shrinkage Type (eutectic, directional and equiaxed) Volume (small, medium, large) 3. Slag/Dross Formation Tendency 4. Pouring Temperature 5. Section Modulus (stiffness of casting geometry) 6. Modulus of Elasticity (stiffness of alloy itself)
The white paper includes examples of how to apply these parameters to component design; formulas for calculating stress, loads and stiffness; and a chart illustrating the application of the various principles to a specific part. The paper also lists resources for additional information. To obtain a copy of the white paper, visit www.afsinc.org/whitepapers.
