Modular workpiece carrier systems in mechanical engineering

Process reliability, component protection and automation

In the manufacturing of precision parts, component positioning, cleanliness, and handling accuracy determine quality, reject rate, and reproducibility. For production and quality managers, this means:
Every movement must be perfect. Every component must be protected. Every process step must be traceable.

ZELL Part carrier systems were developed precisely for this purpose – as a modular, machine-compatible system that integrates seamlessly into existing production environments – including in and around machine tools from DMG Mori, EMAG, Grob, Hermle, and many others.

Automatable feeding – less waste, higher process stability

In precision parts manufacturing, automated feeding is a challenge:
Many components are small, complex, sensitive – and must not jam, become contaminated, or be damaged on the way to the machine.

ZELL Part carriers ensure exact, defined singulation, with which robots, gantries, or linear conveyors can reliably grip and feed components – without intermediate buffers or manual intervention.

Protection of high-precision components – up to quality assurance and packaging

Precision requires protection – especially for surfaces with tight tolerances or coatings.
ZELL workpiece carriers secure components in form-fitting holders: free of stress, with precise positioning, and without friction points.

This minimizes:

❌ Micro-damage to functional surfaces

❌ Defect patterns due to improper handling

❌ Rejects due to mechanical stress during repackaging

✅ Components remain in the same position – from manufacturing to cleaning and final inspection.

Flexibly adaptable – precisely for component, machine and QA process

Despite standardization, the system remains individually adaptable:
Based on proven stainless steel/plastic basic carriers, ZELL develops customer-specific holders (clips), tailored to:

  • Machine fixture and interference contours
  • Workpiece geometry, tolerance requirements, axis clearances
  • ESD requirements or chemical resistance
  • Traceability via RFID, engraving or DMC

For the production manager, this means: once coordinated - permanently ready for use.

Integration into the overall process – from raw part handling to packaging

ZELL Part Carrier systems connect what is often planned separately in many factories:
Machine automation, internal logistics, cleaning, testing, and packaging.

The same carrier system runs through:

  • Feeding to the processing machine
  • Removal & return
  • Transfer to QA / Inspection
  • Final packaging or outsourcing

No re-warehousing. No intermediate containers. No risk of loss.

The advantage for the quality manager: full traceability – and a defined position across all steps.

Your Benefits at a Glance – From a Production & Quality Perspective

Reliable Feeding for Robotics & Machines – compatible with DMG Mori, Grob, EMAG, Hermle, and industrial robotics

Repeatable Component Positioning – ideal for automated manufacturing and testing

Reduced scrap through component protection – especially for sensitive precision parts

Modular and cost-effectively adaptable – carrier remains the same, only holder (clip/multiclip) varies

Integrable into logistics & quality assurance – one carrier for all process steps

Long-term use & cleaning suitability – stainless steel, PA6GB30, optionally ESD & silicone-free

🎯 Repeatable feeding

Precise positioning for robot-assisted CNC loading.

🛡 Component protection

Form-fitting clips prevent micro-damage to precision parts, even during cleaning and transport.

🔄 Process integration

A carrier for transport, processing, testing & packaging – without reloading, without media discontinuity.

Fewer interfaces, greater process reliability.

Production managers benefit from leaner processes, fewer downtimes, and easier component handling.
Quality managers gain continuous control, reduced sources of error, and clear component identification.
System integrators save time during commissioning and system planning thanks to standardized interfaces.

ZELL Part Carrier systems – when precision, protection, and automation need to be considered together.

📥 Raw part handling

Parts are loaded directly into the carrier – manually, by robot, or by "random bin picking."

🛠 Machining

Feeding to the CNC machine or assembly unit – carrier remains in the process.

🔬 Quality control

Testing of parts directly in the carrier – with precise positioning and traceability.

📦 Final Packaging / Logistics

Automated repacking or shipping in customer packaging – optionally directly from the ZELL carrier.

FAQ

How does the carrier reduce waste?
Exact positioning prevents collisions, micro-damage and incorrect feeds – especially for sensitive milled or turned parts.
What does "robot-compatible" mean at ZELL?
All holders are designed so that common robots and gripping systems can grip and release them safely without repositioning.
Can I also use the same carriers for packaging?
Yes – the components remain in the same carrier from processing to final packaging. Automated repacking into customer-specific packaging is also possible.
