Foundry Request for Quote (RFQ)
With the initial list of potential casting vendors available, your request for quotation should be prepared in a way to insure that a foundry knows all the details that impact him so that a valid quotation (both cost and time) can be developed.
The information that should be included in your RFQ should include, but not be limited to:
- Legible, proper revision level, drawings and other portions of the data package that alter or expand upon the drawing requirements.
- Casting process
- Quality requirements
- Tooling data: Are you able to furnish casting tooling (patterns, wax molds, core boxes) or will new tooling need to be produced by the foundry
- Quantity required, both production quantity and first article, if required
- Required delivery dates, including both first article and production quantity
- Machining stock and flatness requirements if you do not have a separate casting drawing
- Non destructive testing requirements
- Casting documentation requirements (chemical analyses, mechanical property determination, etc.)
With this basic information included in your own RFQ, foundries should be able to respond on a timely basis. Due to the time and cost required to develop a good production casting estimate, foundries, especially those whose order books may be full, will depend upon the information you provide to initially screen the RFQ to insure that they have the technical capabilities and that the potential job fits their own business model in terms of quantity, revenue generation and other factors. As the business level at most foundries continuously varies, even a foundry who has done work for you in the past may "no quote" due to their current business conditions and projected production capacity when the job may actually reach their facility.
