What is Zenithin's quality control process?

Our process is built on three stages: 1) Incoming Quality Control to verify raw materials; 2) In-Process Quality Control with continuous inspections; and 3) Final Quality Control, where every completed part is 100% verified against drawings using advanced CMMs and metrology equipment before shipment.

Is Zenithin's quality management system certified?

Yes, Zenithin's quality management system is ISO 9001:2015 certified, ensuring our processes and products meet rigorous international standards for quality.

What quality inspection equipment does Zenithin use?

We utilize advanced metrology equipment including Coordinate Measuring Machines (CMMs) for sub-micron accuracy, Digital Height Gauges for rapid 2D measurements, and Surface Roughness Testers to verify critical surface finishes.

Uncompromising Quality Control

For us, quality is not an action, it’s a culture. Our ISO 9001:2015 certified quality management system ensures every component we deliver is a perfect reflection of your design intent.

A Process Built on Precision: From Raw Material to Final Shipment

1. Incoming Quality Control

We verify all incoming raw materials against their certificates and your specifications to ensure quality starts at the source.

2. In-Process Quality Control

We perform continuous in-process inspections, including first-article and operator checks, to prevent any deviations in real-time.

3. Final Quality Control

Every completed part is 100% verified against your drawings using our advanced CMMs and metrology equipment before shipment.

Technology That Guarantees Precision

Coordinate Measuring Machine

Provides sub-micron accuracy for verifying complex 3D geometries and critical GD&T features on your
parts.

Digital Height Gauge

Used for rapid and precise measurement of critical 2D features like step heights, depths, and center-to-center distances.

Surface Roughness Tester

Precisely measures surface roughness (Ra) to verify that functional surfaces for sealing or bearing meet your exact specifications.

ISO 9001:2015 Certified

Our quality management system is fully compliant with and certified to the ISO 9001:2015 standard.

This certification reflects our deep commitment to operational excellence, continuous improvement, and consistently meeting and exceeding customer expectations.
