Our Quality Control Commitment
Gain a deep understanding of our quality process to ensure that your project proceeds smoothly to the highest standards.
Our Inspection Standards
Dimensional inspection standard: For the key dimensions indicated on the drawing, select appropriate measuring instruments to inspect and record the specified dimensional data against the valid version of the drawing. For other dimensions (only for compliance verification), only non-conforming data can be recorded. If no key dimensions are marked, the dimension with a decimal point shall be the key dimension.
The appearance inspection standards for prototype and production parts include color, screen printing, surface treatment, appearance, inserts, packaging, etc., which meet the requirements of the drawings. Defects are generally based on the drawings. If not specified in the drawings, refer to the following requirements.

Discoloration
|
The color meets the requirements of the paper and is not allowed
|
The color meets the requirements of the drawing, and slight discoloration within a visual inspection range of 60cm is allowed, and it is not visible beyond a range of 80cm
|
The color meets the requirements of the drawing, and abnormal colors are allowed
|
|
Watermark/Yellow spot
|
No visible watermarks or yellow labels allowed
|
Visually indistinct is acceptable, and it is allowed to visually inspect within 60cm of the product, with a slight distance exceeding 80cm and not visible
