The right supplier relationship should simplify production, not add risk. Evaluating your metal stamping company means looking at more than price or proximity. It’s about how consistently they deliver, how clearly they communicate, and how willing they are to adapt when your program changes.
Over time, even a once-reliable vendor can start showing cracks, like missed deadlines, inconsistent quality, slow responses, or constant excuses when problems surface. If you’re starting to wonder whether those issues are becoming patterns, it may be time to reassess your partnership.
Here’s what to look for when evaluating your metal stamping supplier, and how to recognize when it’s time to move on.
-
Quality Issues Keep Creeping Back
One bad lot is frustrating. Recurring defects are a risk to your brand and your customers. Unstable SPC data, out-of-tolerance holes, inconsistent edge conditions, or cosmetic misses force rework and slip dates. A precision-focused metal stamping manufacturer should prevent those surprises with robust APQP, in-process checks, and certified systems – not apologize for them after the fact. Principal backs production with rigorous quality control and the right certifications (IATF 16949:2016, ISO 14001:2015) to keep quality predictable at scale.
-
Lead Times Stretch (And Communication Goes Quiet)
Long lead times are hard enough. Silence makes them worse. If your vendor disappears between PO and delivery, you’re left guessing on tool readiness, capacity, and ship dates. Expect a custom metal stamping partner that’s proactive: clear launch plans, frequent status updates, and honest recovery options when demand shifts. Principal’s engineers and program teams stay engaged from kickoff through shipment so you’re never chasing answers.
-
Every Change Request Turns Into a Change Order
Programs evolve: materials shift, a datum moves, a tolerance tightens. When minor tweaks trigger major delays or a parade of upcharges, your vendor isn’t set up to support you. Look for in-house tooling design and build, plus adjacent processes like CNC machining and automated assembly. That structure shortens iterations and absorbs change without chaos. Principal integrates in-house tooling, stamping, fine blanking, machining, and assembly all under one roof, so adjustments move quickly and stay aligned.

You’re Coordinating Three Suppliers to Ship One Part
If you’re brokering between the stamper, a separate machine shop, and a third-party assembler, you’re adding time, touches, and risk. Consolidation matters. A single metal stamping company with value-added operations – tapping, counterboring, grinding, orbital riveting, automated assembly – can deliver a finished, inspection-ready component while reducing your supplier count. Principal’s one-stop model streamlines production and accelerates speed to market.

Price Looks Good on Paper; Total Cost Tells a Different Story
A low unit price can hide scrap, schedule slips, and quality escapes. Total cost includes engineering churn, freight expediting, premium labor to sort or rework, and the opportunity cost of a late launch. A better partner helps you reduce total cost with smarter tooling, stable processes, and durable capacity planning. Principal’s full-service approach of precision metal stamping, fine blanking up to 700 tons, CNC machining, and automated assembly cuts handoffs and keeps programs predictable.
How a Better Partner Shows Up
- Early engineering support. Collaborative DFM, tool design input, and realistic timelines prevent surprises later. Principal’s engineers work directly with your team to align form, fit, and function before steel is cut.
- Integrated capabilities. Tooling, custom metal stamping, fine blanking, machining, and assembly in one facility reduce lead time and risk.
- Certified, measured, documented. Automotive-grade quality systems with the certifications to match keep audits and production smooth.
- Capacity with range. Short runs, PPAPs, and high-volume production handled under the same roof give you flexibility without a learning curve.
A Quick Self-Check for Buyers and Engineers
- Are quality issues recurring instead of trending down?
- Do you have to pull updates instead of receiving them?
- Does every ECO feel like a fire drill?
- Are you managing multiple vendors to ship a single part?
- Is the “cheapest” option costing you the schedule?
If the answer is yes to two or more, it’s time to rethink your metal stamping supplier. The right partner protects your timeline, your budget, and your reputation.
