Quality Control
We don’t just inspect quality at the end—we build it into every part, every step.
Quality is not just a final step—it’s our foundation
At SYZ Machine, quality starts at the source—not just at the final check.
We follow a fully implemented ISO 9001 Quality Management System, with inspections from raw material to packaging.
Our lab is equipped with precision tools, thread gauges, hardness testers, and salt spray chambers for in-process and final checks.
Our experienced QA team works side-by-side with engineers to ensure dimensional accuracy, durability, and performance.
You receive more than compliant parts—you get reliable, specification-matched solutions built to perform.

Inspection Process to Ensure Quality
To ensure that every rod end meets our performance and durability standards, we conduct a series of thorough inspections throughout the manufacturing process.
Dimensional Inspection
All critical dimensions are checked using calibrated tools to ensure precise fit and compatibility.
Visual Inspection
Each part is visually inspected for defects, scratches, burrs, or deformation before assembly and packaging.
Radial Play / Torque Test
We measure radial clearance and rotational torque to ensure smooth movement and consistent joint tightness.
Thread Gauge Inspection
All threaded components are tested with go / no-go gauges to verify thread accuracy and compatibility.
Material Verification
Material composition is verified as needed to ensure the correct grade of steel or alloy is used.
Hardness Testing
Components are randomly tested for surface or core hardness to confirm heat treatment effectiveness.
Plating Thickness Check
Coating thickness is measured using specialized tools to ensure adequate corrosion protection.
