When Precision Meets Trust: A German Engineering Leader Visits Our Facility

In the world of precision manufacturing, trust isn’t built overnight—it’s earned through every perfectly machined surface, every dimension delivered within tolerance, and every deadline met without compromise. For years, we at Customparts-mfg.com have been quietly delivering high-precision CNC turned parts to one of Germany’s most respected technology innovators. But sometimes, a single day can transform a solid supplier relationship into a strategic partnership. That’s exactly what happened when the Strategic Procurement team from our customer paid us a visit.

This is the story of how one factory tour became a turning point in our collaboration—and why it matters for anyone looking to understand what true manufacturing partnership looks like in 2026.

The Visitor: A Legacy of Innovation in Human-Machine Interaction

To understand the significance of this visit, you need to understand who walked through our doors.

our customer, headquartered in Rottweil—Germany’s oldest city—is not your average manufacturer. Founded in 1971, this family-owned company has spent over five decades perfecting what they call "the art of human-machine interaction. With approximately 150–200 employees across their operations and an annual output exceeding 12 million components, they are one of Europe’s most prolific suppliers of electromechanical solutions.

But numbers only tell part of the story. What truly sets they apart is their relentless drive for innovation. With roughly 200 patents in their portfolio and the prestigious TOP 100 Innovator Award under their belt (ranking among the top 10 companies in the "Innovation Processes and Organization" category), they have reinvented themselves four times—from punched cards to magnetic strips, from chip cards to RFID technology. Today, their product ecosystem spans:

• Encoders & Switches – including their flagship 580 Series incremental encoders with touch-sensing capabilities
• Ticketing Systems – used in parking facilities and public transit worldwide
• Combi Readers – supporting RFID, NFC, barcodes, and QR codes
• Payment Terminals – secure transaction hardware
• Integrated System Solutions – complete electromechanical assemblies

Their technology powers everything from premium kitchen appliances and professional cooking equipment to EV charging stations, self-service kiosks, toll booths, gaming systems, and medical technology devices. When you tap your smartphone at a parking meter in Europe, there’s a good chance their engineering is behind that interaction.

The Starting Point: Years of Precision CNC Machining Service

Our relationship didn’t begin with this visit. It began years ago, with custom precision manufacturing work: CNC turned parts.

For our customer, these components represent the critical interface between their sophisticated electronics and the physical world. Encoder shafts must rotate with absolute smoothness. Switch actuators must engage with tactile perfection. Every micron matters when your end customer is interacting with a payment terminal or an industrial control panel multiple times per day.

We delivered. Consistently. Meeting tight tolerances, managing complex geometries, maintaining surface finishes that exceeded specifications. Our CNC lathe department became a quiet but reliable extension of their supply chain—producing the precision components that form the mechanical backbone of their encoder and switch product lines.

But here’s the thing about successful supplier relationships: they often suffer from a kind of "specialization trap." When you’re really good at one thing—say, precision CNC turned parts—your customer assumes that’s allyou do well. They stop looking further. They stop asking questions.

That was exactly where we were with ddm our customer. Great relationship. Solid delivery record. But our potential as a comprehensive manufacturing partner remained largely untapped.

The Visit: Walking Through Capability, Not Just Capacity

When the Strategic Procurement team arrived at our facility, they came prepared with questions, expectations, and—as it turned out—some preconceptions about what we could offer.

What they found was something altogether different.

Beyond the CNC turning capability

As we guided our customer through our production floor, the first revelation came in our CNC machining centers. Yes, they knew we did precision turning. But witnessing our 5-axis machining capabilities, our ability to handle complex multi-sided components, and our integrated quality inspection processes gave them a new appreciation for the breadth of what we could deliver.

Then came the real eye-openers.

One Stop Solution for Injection Molding Parts

In our samples display room, our guests saw firsthand how we transform raw plastic granules into precision-engineered components. For a company, whose encoder housings, card reader bezels, and payment terminal enclosures require tight dimensional control, cosmetic excellence, and material consistency—this was a revelation.

We discussed material selection (ABS, PC, PA, POM, and specialty engineering plastics), mold flow analysis, gate design optimization, and how we manage insert molding for metal-plastic hybrid assemblies. The conversation shifted from "you make our shaft" to "you could mold our entire encoder housing." 

Sheet Metal Fabrication Solutions

Laser cutting, CNC punching, bending, welding, and finishing. Their ticketing systems, payment terminals, and kiosk solutions all require precision-fabricated enclosures, mounting brackets, and structural components.

For automated laser cutting cells, robotic bending cells, and  welding and powder coating, they seeing that CMI can integrate a complete set of sheet metal fabrication process resources and provide professional one-stop solutions. The procurement team began connecting dots. "We currently source these sheet metal parts difficult in Europe. one of them noted. "You could consolidate all of this for us." 

Forging & Casting: The One-Stop-Shop Realization

We also walked them through our supply chain partnerships with certified forging houses and die-casting foundries, our in-house secondary machining operations, and our rigorous material traceability protocols. 

This wasn’t just a precision machine shop. This was a comprehensive manufacturing ecosystem capable of taking different processing technology.

"This is exactly what we’ve been looking for,"said one of the visitors. "A partner who understands that our products aren’t just individual components— And now we know you can support us across the entire value chain."

Why This Matters: The Strategic Logic of Consolidation

The enthusiasm from their team wasn’t just politeness—it was strategic clarity. In today’s global manufacturing landscape, supply chain fragmentation is one of the biggest hidden costs facing OEMs. 

Each handoff introduces complexity. Each supplier requires separate quality agreements, separate logistics coordination, separate payment terms, and separate risk management. When tolerances don’t align between Supplier A’s shaft and Supplier B’s housing, finger-pointing begins. Lead times compound. Inventory buffers multiply. Total cost of ownership balloons.

Now imagine consolidating all of this with a single manufacturing partner—one quality system, one project manager, one logistics flow, one relationship to nurture. That’s not just convenience. That’s competitive advantage.

Looking Ahead: From Supplier to Strategic Partner

The visit concluded with clear commitments from both sides. Their Strategic Procurement team expressed their intention to deepen the partnership significantly:

• Expanded CNC scope: Moving beyond simple turned parts to complex 5-axis milled components for next-generation encoder and switch designs
• Injection molding integration: Transitioning housing and enclosure production to our facility
• Sheet metal consolidation: Bringing bracket, chassis, and structural component sourcing under our roof
• New product development collaboration: Engaging our engineering team earlier in the design phase to optimize manufacturability across all process disciplines

"This visit has been incredibly meaningful for us,"the team told us before departing. "We’re going back with a completely new understanding of what’s possible. This changes everything."

The Bigger Picture: What Manufacturing Partnership Means in 2026

This story resonates far beyond a single customer visit because it illustrates a fundamental shift happening across the manufacturing industry right now.

The era of transactional procurement—where buyers flip through catalogs and pick the lowest-priced supplier for each component—is giving way to something more sophisticated. Today’s leading OEMs are seeking manufacturing partners, not vendors. They want collaborators who understand their products holistically, who can advise on design for manufacturability, who can scale with them across geographies and technologies, and who view quality not as a metric but as a philosophy.

At Customparts-mfg.com, we’ve built our entire operation around this philosophy. Committed to providing customers with one-stop production solutions for industrial components. Whether it’s a ±0.005mm tolerance on a CNC-turned encoder shaft, a cosmetic Class A surface on an injection-molded payment terminal bezel, or a structurally optimized sheet metal for an industrial control panel—we bring the same rigor, the same attention to detail, and the same commitment to excellence.

Closing Thoughts

Trust is easy to talk about but hard to build. It’s built in the quiet moments—when a shipment arrives exactly on spec, when a problem is solved before it becomes a crisis, when a capability is demonstrated rather than claimed.

That site visit proved something we’ve always believed: when you show customers not just what you can do, but how deeply you understand their world, partnerships transcend transactions. We’re not just making parts for them anymore. We’re helping shape the future of human-machine interaction—one precision component at a time.

And that, quite honestly, is exactly the kind of partnership we live for.
