Focus	Design validation, functional testing, mechanical fitting
Volume	1–10 units typically
Turnaround Time	Fast iteration (within days)
Cost	Higher per-unit cost due to manual labor and no tooling amortization

Mass Production Phase

Aspect	Details
Methods	Injection Molding, Die Casting, Sheet Metal Stamping
Focus	Efficiency, consistency, cost reduction
Volume	100–10,000+ units
Tooling	High upfront cost but amortized over volume
Lead Time	Longer setup but lower per-unit cost once running

Dive Deeper: My Transition Strategy

Here’s how I usually manage the transition from prototype to production to maximize output and ROI:

• Phase 1 – Prototyping: Validate the drone’s structure, propulsion, and payloads using CNC aluminum mounts and 3D printed frames.
• Phase 2 – Pre-Production: Use hybrid methods—off-the-shelf ESCs and machined brackets while testing mold designs.
