Buyer RFQ Guide

Complete RFQ Package Guide for Custom Metal Parts

This OEM/ODM RFQ guide helps buyers prepare custom metal parts, plastic components and finished assemblies for engineering review, quotation and production planning.

Depending on the project, your RFQ may route to CNC machining, metal stamping, welding fabrication, plastic injection molding or OEM assembly.

What This Guide Covers

• A complete RFQ package should connect the engineering requirement, commercial requirement and production expectation in one clear file set.
• For custom metal parts, the most useful RFQ package usually includes drawings, CAD files, material specifications, tolerance requirements, surface finish standards, quantity, target schedule, packaging needs and inspection documents.

Core RFQ Information

• Product name, application and assembly position.
• 2D drawing with dimensions, tolerances, threads, surface finish notes and revision number.
• 3D CAD file such as STEP, STP, IGES or native CAD where available.
• Material grade, thickness, hardness, heat treatment and equivalent material rules.
• Surface treatment requirements such as anodizing, zinc plating, powder coating, e-coating, polishing or passivation.
• Prototype quantity, production batch quantity and estimated annual demand.
• Inspection requirements including FAI, dimensional report, CMM report, material certificate or surface treatment report.

How To Reduce Quotation Back-And-Forth

• Avoid sending only a photo or incomplete drawing when dimensional accuracy, assembly fit or finish appearance matters.
• If several materials or finishes are acceptable, state the preferred option and allowed alternatives. This helps the factory compare cost and manufacturability without guessing.
• If the part belongs to an assembly, include related mating dimensions or assembly drawings so the engineering team can evaluate functional risk.
