# Aluminum Casting Prototype to Production: How to Scale from 10 Pieces to 10,000
Many buyers face a frustrating problem: they start with one supplier for prototypes, encounter issues, and then scramble to find a different manufacturer for production. This guide shows how to scale smoothly using the same tooling, alloy, and process from day one.
Why Prototype-to-Production Transitions Fail

The common mistake is prototyping with CNC machining or 3D printing, then switching to gravity casting for production. Properties, dimensions, and defects all differ between processes.
The smart approach: Prototype with your production process using production-intent tooling (permanent molds), production alloy (A356-T6), and production heat treatment.
For medium-volume programs (500-20,000/year), gravity casting offers the best continuity.
