Smith Foundry has the ability to help with casting design optimization. While the basic design elements are up to the customer, we are always looking at ways to cut costs out in a manner consistent with the overall project.
Some of the design criteria we look for in the quoting process are:
- A 3D model and a 2D dimensioned drawing showing tolerance requirements
- Material specification
- Casting weight (if no model provided)
- Estimated order volume and estimated annual usage
- If there is a preferred parting line for application or critical as-cast dimensions, these should be noted
With this basic information, we are able to begin collaborating with our pattern makers and other subcontractors to develop quotes for their work. Some of the typical design elements we look for are:
- Is there adequate draft where needed?
- Are there unnecessary thin sections?
- Are there Adequate radii and fillets?
- Are there features that could be revised to eliminate a need for cores?
- Is there adequate machine stock where needed?
- Is there another material that should be considered?
- Is there a way to simplify a complicated design?
We partner with a number of subcontractors with a wide range of capabilities in order to provide the level of service that meets your needs in terms of volume, lead time, dimensional accuracy, part intricacy, and price. Pattern materials range from wood for low volume, urethanes and aluminum for higher volumes and/or better accuracy. CNC machining tooling is getting to be the norm, but traditional construction methods are still used for simple designs and when appropriate.
