Quality Control & Tolerances

In aluminum casting, quality is not inspected in at the end — it is engineered into every stage of the process. At NAITE TECH, we implement a structured quality control system that aligns casting design, tooling development, molten metal control, and post-processing inspection into one closed-loop workflow. This ensures dimensional stability, metallurgical integrity, and repeatable production performance.

At NAITE TECH, quality is engineered into every stage of aluminum casting — from alloy verification and melt control to final dimensional inspection. We ensure consistent casting integrity, controlled porosity, and reliable dimensional performance for both prototype and production runs.

As-cast tolerances vary by process:
Die Casting: typically ±0.05–±0.15 mm
Gravity Casting: typically ±0.2–±0.5 mm
Sand Casting: typically ±0.5 mm and above

For functional or critical features, secondary CNC machining can achieve tighter tolerances down to ±0.01 mm where required.

As-cast tolerances vary by process:

Melt composition verification and process monitoring

In-process inspection during casting production

Final dimensional verification using calibrated equipment (CMM upon request)

Material traceability and inspection reports available upon request

Compliance with specified tolerances, GD&T requirements, and technical drawings
