HC Bottle Cap Manufacturing Co., Ltd. Bottle cap inspection projects ensure that bottle caps meet quality standards during the production process and can effectively guarantee a series of tests for their sealing, durability and applicability.
| Test Type | Purpose | Test Method | Requirements/Notes |
| Sealing Test | Ensure the sealing effect between the cap and bottle mouth. | Check whether the surface of the bottle cap is flat and complete. | Ensure the sealing effect is flawless to prevent leakage. Applicable for liquid products without gas. |
| Twist-off Force Test | Test the torque value when tightening or opening the cap. | Measure the torque required to tighten or open the cap. | Twist-off force should generally be under 1.0 N·m. Higher values may affect user convenience. |
| Sealing Test (Liquid) | Test for leakage prevention in liquid products. | Invert water inside the bottle and vacuum to check for leakage. | Ensure no liquid leakage occurs, verifying the cap's sealing function. |
| Gas Tightness Test | Test for gas retention in products containing gas. | Positive and negative pressure testing to check for gas leakage. | Ensure that gas is sealed inside the bottle, preventing bubbles or gas loss. |
| High Temperature Test | Evaluate the cap's performance under high-temperature conditions. | Expose the cap to temperatures of 90°C and 121°C and observe any deformations. | Cap should not deform or fail under heat treatment or high-temperature environments, maintaining its sealing function. |
HC Bottle Cap Manufacturing Co., Ltd.’s bottle cap packaging inspection program ensures that the bottle caps are effectively protected throughout the entire transportation and storage chain, ensuring that the bottle caps remain intact when they reach the end user.
| Test Type | Purpose and Expected Outcome |
| Compression Test | Check if the carton can withstand external pressure during stacking or transportation, preventing the carton from breaking and protecting the internal bottle caps from damage. The expected outcome is that the carton remains intact under a certain level of external pressure, with no damage to the internal bottle caps. |
| Vibration Test | Test the stability and shock resistance of the carton packaging during transportation, ensuring that the bottle caps remain secure and undamaged during vibrations or shaking. The expected outcome is that, even during transport, the bottle caps remain intact and do not become loose or damaged due to vibration. |
