Why Standard Contract Manufacturers Don't Work for 10-150 Unit/Year OEMs
Mid-volume OEMs building 10-150 units/year face a manufacturing gap - too complex for generalist CMs, too small for large design-build firms. Here is what to look for instead.
The Mid-Volume Manufacturing Gap
There is a well-documented gap in contract manufacturing for growing OEMs building 10-150 units per year. The challenge is not finding someone who can build your equipment, but finding someone whose business model is actually designed for your volume.
Standard contract manufacturers are optimized for either high-volume (1000+ units/year) or are generalist shops focused on low-complexity work. Neither model works well for precision capital equipment at mid-volume.
Why Large CMs Don't Work for Mid-Volume
Large contract manufacturers are built for speed and scale. They have invested in high-speed automation, minimal labor per unit, and tight cost control - all dependent on volume. For a 10-unit or 50-unit program, their model doesn't work. They require volume commitments and minimum order quantities that don't make sense for your business, and pricing built around high-volume economies.
Why Generalist CMs Don't Work for Precision Equipment
Generalist contract manufacturers (often called "job shops") can take on small, low-complexity work quickly. But precision capital equipment has requirements they typically don't meet:
- •Engineering oversight - Not just building to prints, but understanding the design
- •Precision metrology - Verification of tight tolerances
- •Documentation rigor - First-article inspection, traceability, configuration control
- •Program continuity - Same team across builds, institutional knowledge, lesson capture
The Program Ownership Gap
In large CM operations, your program is one of hundreds. Program ownership and continuity of expertise are lost between builds. What mid-volume programs actually need is a CM that maintains continuity of expertise across builds with stable teams, accessible engineering, lesson capture, and proactive risk flagging.
What to Look for in a Mid-Volume Partner
Designed for Your Volume
A manufacturing partner should be explicitly designed for 10-150 units/year programs - not trying to fit you into a high-volume model or a job-shop model.
Deep Industry Expertise
Look for experience in your specific domain - photonics, defense, life sciences, metrology, etc. Domain expertise is what allows engineering engagement and problem-solving.
Team Continuity and Access
Can the same core team work on your program across builds? Is there a single technical point of contact who understands your system end-to-end?
Scalable Infrastructure
Can they grow with you as volume increases? Do they have the metrology, facilities, and team to support scaling from 10 to 100 to 150 units/year?
