How does your factory ensure product consistency (color difference and thickness tolerance) for long-term export orders?
2026-07-28
Our factory implements a strict batch control process:
Color difference: Each color adjustment uses a spectrophotometer (ΔE < 1.0 color difference value control), and a standard color sample is retained for comparison.
Thickness: We use an online laser thickness gauge for real-time monitoring to ensure that thickness tolerance is strictly controlled within ±0.3mm, far exceeding the industry standard (JC/T 2704-2022 requires ±0.5mm).
