Cosmetic Packaging / Container Visual Inspection

● Color Criteria:
- Due to production technology limitations, the color tolerance for the entire batch of products will be provided based on the customer-approved sample. A color deviation of plus or minus 5% is considered an acceptable range.

● Surface Criteria:
- No presence of debris, insects, dust, or oil residue on the inner surface of tubes, inner cups, or bottles.
- The surfaces should be free from debris, insects, dust, or oil residue.
- No missing material, cracks (as long as it doesn't affect secondary processing or assembly functionality).
- No damaged or incorrect components (as long as it doesn't affect secondary processing or assembly functionality).
- Scratches (length > 5mm, width > 0.2mm, more than 1).
- Deformation (as long as it doesn't affect secondary processing or assembly functionality).
- Bubbles (surface ≥ 0.15mm, more than 1; other areas ≥ 0.15mm, ≤ 0.5mm, more than 3).
- Black spots (surface ≥ 0.15mm, more than 1; other areas ≥ 0.15mm, ≤ 0.5mm, more than 3).
- Pits (> 0.5mm, more than 2 on the same surface).
- Blemishes (more than 10 spots > 0.2mm within a 10mm² area).
- Injection gate should not protrude more than 0.3mm above the surface.
- No excessive adhesive.
- No detachment or breakage of lenses (as long as it doesn't affect secondary processing or assembly functionality).

● Logo Criteria:
- Incorrect content or color.
- Fraying, notches, or teeth-like features ≥ 0.3mm.
- Misalignment in printing, embossing, or hot stamping > 0.5mm.
- Severe tilt affecting identification.
- Overlapping or missing prints affecting identification.
- Ink smears > 0.3mm and more than 3 points.
- Vertical or horizontal displacement ≥ 1mm², ≤ 1mm².

Cosmetic Packaging / Container Functional Inspection

● Assembly Criteria, checking for proper assembly, operation, or application
1. Lipstick and Panstick Shell
- Smooth rotation of the middle barrel (tube) without free spinning, with locking positions both up and down.
- Smooth rotation after assembly of the middle barrel and base. The middle barrel should be firmly seated, not prone to dislodgment.
- Aluminum middle barrel and sleeve must be securely assembled, with no detachment during rotation.
- Separation pull force for middle tube and base ≥ 3000g.
- Proper sealing of the cap and base, with an opening / closing pull force between 300g and 3000g.
- Inner cup inside the middle barrel should withstand a pressure of ≥ 0.1kgf.
- Torque for the inner cup: 0.03 ~ 0.4 kgf.
- Top and bottom force for the inner cup (≥ 1 kgf).
2. Lip Gloss, Eyeliner, Mascara, Bottles, Jars, and Soft Tube Shells
- After assembling the cap and base, smooth rotation should be achieved without free spinning or misalignment.
- Separation pull force for the inner plug and base > 2000g.
- Pull force for the top cap and brush rod > 5000g.
- Pull force for the brush head and brush rod > 1500g.
- Pull force for the base and inner plug > 1500g.
- Pull force for the soft tube and inner plug > 1500g.
- Sealing strength of the soft tube end should withstand a downward pressure of ≥ 5000g/10 seconds.
3. Paper Jar Shell
- Properly functioning latching during opening and closing, with no significant latching misalignment issues.
- Opening and closing force approximately between 350g and 1500g.
- Pull force for the lens and inner sleeve > 1500g.
4. All Cosmetic Primary Packages
- Gap tolerance ≤ 0.2mm.
- Gap between the cap and base ≤ 0.2mm.
- No incorrect dimensions.
- After being dropped from a height of 80cm onto marble three times, no component should break or detach.
5. Logo, Paint, Plating
- Tested using 3M's 810 tape; after applying and removing, it should remain firmly attached, with an accepted standard of detached area less than 1mm² or vertical or horizontal displacement between ≥ 1mm² and ≤ 1mm².
