Quote FAQ
Questions that help buyers compare real RFQ paths
What should an OEM buyer prepare before asking for an aluminum casting quote?
Prepare drawings or 3D files, alloy or performance requirement, expected annual volume, machining scope, inspection requirements, packaging or export notes, and target timing. This reduces assumptions in tooling, MOQ, and unit-price discussions.
Why should a quote separate tooling, samples, machining, and production assumptions?
Separated assumptions help buyers compare suppliers more fairly. Tooling cost, sample loops, CNC machining, pressure or leak-related checks, surface finishing, and production quantity can each change the real landed cost.
Which quote page should buyers open first?
Use the supplier comparison page for sourcing decisions, the second-source page for backup supplier or transfer-tool reviews, the MOQ/tooling page for commercial assumptions, and the product-family quote pages when the drawing is for pump housings, valve bodies, gearbox housings, EV motor housings, EV battery enclosures, compressor housings, intake manifolds, thermal-management heat sinks, electrical mounting hardware, or automotive suspension brackets.
When should buyers move from research pages to the RFQ form?
Move to the RFQ form when the part family, drawing package, target quantity, and key inspection expectations are clear enough for engineering review. If some details are unknown, state them as open assumptions in the RFQ.
