Scaling from a single prototype to production volume is exciting—but it’s also where small oversights can cost big in time and rework. Use this checklist to help ensure your parts are production-ready.

2. Pre-Production Checklist

a) Finalize Material Grade & Thickness

Be precise—different alloys and thickness sets behave differently during cutting, bending, or welding. Clarify metal spec early.

b) Call Out Critical Tolerances Only

Only flag tight tolerances where they matter—leaving the rest looser helps reduce scrap and machining.

c) Define Surface Treatments & Finishes

Clearly state if you need powder coating, wet spray, plating, or special masking—and whether parts are for internal use or aesthetics.

d) Share Clear CAD Files & Flat Patterns

Providing unfolded models or accurate CAD patterns reduces errors in bend placement or hole location in fabrication.

e) Discuss Nesting & Tooling Strategies

Effective nesting can reduce material waste and production time. Ask if standard tools suffice—or if custom tooling is needed.

f) Pre-plan Fixturing & Weld Access

Complex weld assemblies need good access and stable fixtures—highlight your key weld areas to avoid surprises.

g) Run a Small Pilot Batch

A trial run catches fit, finish, or process issues that a solitary prototype might not reveal—better to fix early than later.

h) Define Inspection Methods & Acceptance Criteria

Agree on how parts will be checked—dimensional inspection, sampling rate, or full QA—so delivery meets expectations.
