28x18mm Aluminium Closure Quality Inspection
In our company, the quality inspection of the 28x18mm aluminium closure is one of the core steps in our production process. We conduct a series of strict tests to ensure that each cap meets high standards, guaranteeing customer experience and product safety.
| Test Item | Description |
| Sealing Test | We conduct a sealing test to check the surface condition of the cap after sealing. The test ensures that the seal is defect-free, smooth, and without visible scratches or cracks, guaranteeing the perfect sealing and appearance of the product. |
| Torque Break Test | We perform a torque break test to measure the cap's tightening performance. The ideal torque should be below 1.0. If the torque is too high, the cap may be difficult to open, affecting user convenience. Therefore, we pay special attention to this indicator to ensure that the cap provides sufficient sealing while not being overly difficult to open. |
| Sealing Performance Test | For non-carbonated liquids, we use water inversion and vacuum pumping methods to test sealing performance. This test effectively checks the cap's sealing ability, ensuring no leakage or external contamination, making it suitable for long-term storage of liquid beverages. |
| Gas Tightness Test | For carbonated liquids, we use positive and negative pressure detection methods to conduct a gas tightness test. Through this test, we ensure that the cap maintains its sealing ability in beverages containing gas (such as carbonated drinks), preventing gas leakage and ensuring the bubbles and freshness of the beverage. |
| High Temperature Resistance Test | Our 28x18mm aluminium closures undergo high temperature resistance testing, which includes tests in environments with temperatures of 90°C and 121°C. These tests ensure that the cap maintains good sealing performance under high temperature conditions, making it suitable for different storage and transportation environments. |
Through these rigorous quality inspections, HC ensures that every 28x18mm aluminium closure meets the high requirements of our customers, ensuring the sealing, safety, and durability of the product. We are committed to providing the highest quality aluminium closures and ensuring that no detail is overlooked.
