Your Invisible Capacity, Ready When You Need It


When a surge order hits or a schedule gets backed up, you face two bad options: push the lead time and risk the customer relationship, or overload your floor and risk quality on everything in the queue. Every job you turn away is revenue walking into another shop — one that might not send it back.

Caldwell Manufacturing operates as a white-label overflow partner for larger precision shops. We run your parts to your exact specs and quality standards, completely behind the scenes. Your name stays on every part. We sign an ironclad NDA and non-compete before we ever see a print — we have zero interest in your customer relationships.

You hold the certifications your customers require — AS9100, ISO 13485, NADCAP. We hold ISO 9001:2015 and ITAR — enough to run your overflow to spec, not enough to compete for your accounts. Think of us the way a law firm uses contract attorneys: extra capacity for sudden spikes, without the overhead, without the risk.
