Why Glassware Inspection Methods Matter

Glassware inspection methods must pass strict checks before shipment. Because a small defect can affect the whole batch, Guangzhou Divinio Packaging follows a clear inspection process. Moreover, we document every step so buyers can review the results.

General Appearance Inspection

We conduct general appearance inspection under fluorescent lighting. For color difference judgment, we use a standard light source cabinet with standard indoor lighting. The inspector holds the sample at approximately half an arm’s length from the eyes, about 8 inches. In addition, each accessory receives 3 to 4 seconds of inspection time.

Glassware Inspection Methods: Dimensional Measurement

We take measurements in accordance with the drawing requirements. Therefore, the sampling level is 10 pieces per batch.

We measure dimensions using vernier calipers.
For assembly and fitment areas, we take measurements per drawing requirements.
If the deviation is within 0.5mm, QA and QC determine whether to accept or reject the lot.
If the deviation exceeds 0.5mm, QA and QC determine whether to apply special acceptance, sorting, or rejection.

Glassware Inspection Methods: Special Tests

We conduct special tests at a sampling level of 10 pieces per batch.

High-temperature resistance test: We place the product in a forced-air constant-temperature oven. The product passes if no cracking or breakage occurs.
Fitment test: We assemble the product with its mating components. The clearance shall not exceed the specified standard. Under external force, no noticeable wobbling shall occur.
Imaging test: Under fluorescent lighting, the reflected image shall not be distorted and shall remain clear.
Adhesion test: We apply 3M tape firmly onto the coated surface. After one minute, we peel off the tape. No peeling or detachment shall occur.
Anti-fogging test: This includes a freezing test from -10°C to room temperature, and a hot water test at 80°C ± 5°C. The mirror surface shall remain fog-free.
