Testing Center

State-of-the-Art Inspection Equipment

Brand-name metrology tools in both factories — every geometry, profile, and surface finish can be verified.

Accuracy 1.9 µm · Stroke 900×1200mm

Zeiss CMM — Coordinate Measuring Machine

Measures complex 3D geometries with pinpoint precision. One unit in Dongguan, one in Nantong — your parts are verified on the same class of machine, whichever factory produces them.

1.9 µm accuracy

Nikon V-12B · ±0.001mm

Nikon Profile Projector

Projects part profiles and contours onto a comparison screen — intricate shapes and stamped contours are checked against the drawing quickly and reliably.

100×100mm stage

Trimos · Tesa · ±0.001mm

2D Height Gauges

Trimos and Tesa height gauges verify vertical dimensions and height tolerances on die components and assembled parts — maintaining assembly accuracy part after part.

Up to 700mm range

Nikon MM-60 · ±0.001mm

Nikon Measuring Microscope

Inspecting small parts and ultra-fine details — edge radii, tiny holes, and fine features are measured with confidence, not guessed.

Fine-detail inspection

Verification At Every Stage

How Every Part Gets Verified

Quality isn't a final check — it's built into each step of production.

Drawing Review

Critical dimensions and tolerances flagged before machining starts.

Incoming Material Check

Material certificates and dimensions verified against specification.

In-Process Inspection

First-article and process checks on the shop floor, as parts are made.

Final Measurement

CMM, profile projection, and gauge verification of every shipped part.

Report & Delivery

Measurement report with each order — full traceability, your specs.

Documentation

Full Measurement Reports, Full Traceability

Every order ships with inspection data you can trust and audit.

Dimensional Analysis

Critical dimensions measured and recorded against your drawing, dimension by dimension.

Surface Finish Evaluation

Surface quality checked and reported — verified, not assumed.

Tolerance Verification

Every tolerance class confirmed with calibrated, traceable instruments.

Common Questions

Quality Assurance — Common Questions

What our customers ask about measurement, reporting, and standards.

What quality standards do you follow?

We are ISO 9001:2015 certified. Every component is verified against design specifications and functional requirements, following internationally recognized quality procedures.

What measuring equipment do you use?

Zeiss CMM for complex geometries, Nikon measuring microscopes for fine details, Trimos/Tesa 2D height gauges, and Nikon profile projectors for intricate profiles — high-precision measurement for even tight-tolerance parts.

Can you provide measurement reports?

Yes. Comprehensive measurement reports include dimensional analysis, surface finish evaluation, and tolerance verification — tailored to your quality and certification needs, with full traceability.

How do you reduce production risks?

By verifying every component with state-of-the-art equipment, we minimize rework, prevent defects, and keep quality consistent in mass production.

Which industries do you support?

Automotive, aerospace, electronics, medical devices, and industrial manufacturing — any industry where quality and precision are critical.
