RFQ Checklist
What to Send for a More Useful Manufacturing Quote
Missing information forces a supplier to make assumptions. Those assumptions often explain why quotations differ widely or why cost changes after DFM, material confirmation, or mold design.
Drawings and Revision2D drawing, 3D model, revision, critical dimensions, tolerance notes, and cosmetic zones.
MaterialResin family, exact grade when required, color, additives, recycled-content limits, and compliance needs.
