What Information Does a Factory Need?

The clearer and more complete your package, the better your quote and your parts.

To quote your product accurately and then make it well, a factory needs a clear, complete package of information — not just a description or a photo. The more precisely you specify what you want, the more accurate the quote and the closer the finished parts come to what you intended. Vague inputs lead to vague quotes and surprises later.

What Factories Usually Need

A design or CAD file
Drawings with dimensions and tolerances
The materials to use
Finishes and any surface requirements
The quantity you want
Any standards or special requirements

Why Completeness Matters

Missing information gets filled in with assumptions — and a factory's assumptions may not match yours. Clear specs mean the quote reflects what you actually want, and the parts come back closer to right the first time. This is also how you compare quotes fairly across manufacturers.

A Prototype Can Help, Too

A physical prototype can clear up things a drawing alone can't, but it doesn't replace the specifications — it complements them. The specs tell the factory exactly what to make; the prototype helps them understand it.

Common Mistakes We See

Asking for a quote from a description alone
Leaving out quantity, tolerances, or finishes
Assuming the factory will “figure out” the missing details the way you would

A Good Next Step

A short conversation can help you understand what to prepare so a factory can quote and build your product accurately.
