What specific quality control tests are conducted during the manufacturing the tin boxes?

1. Thickness Measurement:

 to ensure it meets the specified requirements and maintains structural strength.

2. Coating Adhesion Test:

 to the metal surface to ensure they adhere securely and provide effective protection.

3. Impact Resistance Test: 

to assess their resistance to external forces and ensure they can withstand handling and transit without damage.

4. Corrosion Resistance Test: 

to corrosion in different environmental conditions, particularly when exposed to humidity, moisture, or other corrosive elements.

5. Seal Integrity Test:

to verify that they provide adequate protection and prevent contents from leaking or being compromised.

6. Coating Thickness Measurement: 

 to verify they meet the necessary standards and can provide adequate protection to the tin boxes.

7. Compression Test: 

 to evaluate their strength and structural stability, particularly when stacked or subjected to pressure during storage or transport.

8. Environmental Tests: 

to environmental conditions such as extreme temperatures, humidity, or solar exposure to assess their durability under various circumstances.
