Custom Gaging & Fixtures

Inspection that predicts field performance.

We build the gages that close the loop.


We design and build custom gaging in-house, tied directly to the same datums and control schemes used in tooling and stamping.


Fixtures are built, verified, and correlated on real production parts—so measurement results match how the part is actually made and used.

Datum-Matched Gage Design

Datum-Matched Gage Design

We align gaging datums with the same references used in die and press setups.

Measurement results reflect true process behavior, not abstract coordinate systems.

GR&R-Backed Validation

GR&R-Backed Validation

Each gage is verified for repeatability and reproducibility before release.

Confidence in every capability report, audit, and launch.

Thin, Coined & Formed Part Fixturing

Thin, Coined & Formed Part Fixturing

We design fixtures for parts that CMM probes can’t read reliably.

Stable measurement of delicate or flexible geometry.

Sensorized & Automated Gages

Sensorized & Automated Gages

Add contact or non-contact sensors, limit switches, or go/no-go checks for in-line use.

Faster feedback, less manual handling, fewer missed trends.

Correlated Inspection Plans

Correlated Inspection Plans

CMM and custom gage data are correlated at launch.

Eliminates cross-plant variation and arguments over “whose measurement is right.”

Calibration & Maintenance Programs

Calibration & Maintenance Programs

We provide calibration points, adjustment tools, and PM plans.

Long-term consistency and audit readiness.

Frequently Asked Questions (FAQ)

 Yes—send us part prints or CMM data; we’ll create a fixture concept and correlation plan.

 Fixture components are built to 0.0001″; repeatability verified through GR&R studies.

Yes—optical, limit, and height sensors available for in-line inspection or press-side checks.

ELECTRICAL & POWER

Your challenge: Heat rise and torque issues are often traced back to poor flatness or misaligned contact surfaces that weren’t caught by generic inspection.

Our solution: Datum-matched gages and GR&R-backed fixtures replicate real press setup, capturing flatness, planarity, and contact area before assembly.

Your benefit: Reliable, conductive parts that mate cleanly in switchgear or busbar assemblies—validated upstream so failures never reach the field.

ELECTRONICS & SENSORS

Your challenge: Micro-features on terminals and shields can’t be measured repeatably; plating growth or contact deformation escapes detection.

Our solution: Micro-gaging fixtures built from tooling datums, with post-plate correlation to CMM; repeatability proven through GR&R studies.

Your benefit: Stable contact force, consistent connector fit, and traceable quality data that align production and assembly results.

DEFENSE & AEROSPACE

Your challenge: Zero-escape performance under shock, vibration, and thermal extremes—plus audit-ready documentation.

Our solution: Stamping validated on production presses with in-press SPC, buckle and slug sensors, and MIL-grade traceability; capability confirmed by GR&R and PPAP data.

Your benefit: Mission-critical parts that hold tolerance through service life, backed by complete documentation for qualification or re-inspection.

MEDICAL DEVICE & EQUIPMENT

Your challenge: Burrs, deformation, or finish inconsistencies on tiny parts trigger validation failures or biocompatibility issues.

Our solution: Fine-blanked and coined features, controlled bend radii, and post-form inspection that mirrors assembly and sterilization conditions.

Your benefit: Clean, burr-free components that assemble smoothly, pass FDA/ISO audits, and maintain precision through sterilization and packaging.

INDUSTRIAL MACHINERY

Your challenge: High load, vibration, and wear expose forming stress and tolerance drift in brackets, clips, and housings.

Our solution: Progressive dies tuned for uniform forming pressure, real-time feed and part-out sensors, and hardened steels to maintain geometry at speed.

Your benefit: Parts that install easily, hold alignment under vibration, and extend equipment uptime with less rework and maintenance.

MOLDING-INTEGRATED APPLICATIONS

Your challenge: Metal inserts deform or shift during overmolding, causing misalignment and weak electrical contact.

Our solution: Reel-to-reel stamping with carriers designed for thermal stability and mechanical lock; post-mold gage correlation ensures seating accuracy.

Your benefit: Inserts that stay true through molding and assembly, preserving electrical and mechanical integrity and cutting scrap.
