Design Considerations

When producing bronze sand castings as with all casting techniques, there are a variety of design considerations that you must prepare for. Properly locating the parting line reduces the number of cores required and the amount of waste while increasing dimensional accuracy, which helps lower costs for our customers. Uniform casting thickness results in uniform cooling and solidification, as well as distortion-free castings. When uniform cross sections cannot be maintained, gradual changes in cross sections are required. This can be achieved by using a transition radius of 1/3 of the thicker section and blending in the radius with a 15-degree slope line. To minimize problems at intersecting points within the core we use staggered rather than continuous ribs and avoid large, unsupported areas. Maintaining minimum wall thickness will prevent voids and non-fill areas.


With a solid understanding of the process and its advantages, you can confidently select Erie Bronze and Aluminum as the low-cost casting method for creating your metal components.
