Using three-coordinate detectors, height gauges, electronic digital calipers, and measuring projector stress gauges, we thoroughly inspect product appearance and dimensions in compliance with strict customer specifications. All quality control data and test reports are fully traceable. Following rigorous training, operators are qualified inspectors, and all measuring instruments are managed strictly under MSA control.
The product itself is wrapped securely in multi-layer bubble wrap, interior gaps are filled with shock-absorbing foam, and outer packaging utilizes a standard export-specification wooden crate. Customized packaging requests are fully supported.
Equipped with precision laser engraving machines, we can cleanly engrave trademarks, custom logos, scale lines, and serial numbers directly onto products according to customer requirements.
