How do Aluminum Shell Blister Products ensure good sealing performance?

Publish Time: 2024-05-11
Aluminum Shell Blister Products is a critical quality control link in ensuring good sealing performance. The following are several aspects that ensure good sealing performance of Aluminum Shell Blister Products:
Material selection: First of all, it is crucial to choose high-quality blister materials and aluminum materials. The blister material should have good toughness and sealing properties, while the aluminum material requires a smooth and flawless surface to ensure a tight fit with the blister part.
Mold design: The sealing requirements of the product should be taken into consideration when designing the mold. The size, shape and tolerances of the mold must be precise to ensure a tight seal is created during the blister process.
Molding process: In the blister molding process, the control of temperature, pressure and time is the key. The right temperature ensures that the material softens sufficiently, while the right pressure and time ensures that the material fully deforms and fits snugly in the mold.
Edge Treatment: Aluminum Shell Blister Products' edge treatment is critical to sealing performance. The edges should be smooth, burr-free, and tightly integrated with the blister part. The edges can be strengthened through heat sealing, ultrasonic welding, etc. to improve sealing.
Quality inspection: During the production process, products should be subject to strict quality inspection. The sealing performance of the product can be evaluated through air pressure testing, water tightness testing, etc. Unqualified products should be reworked or scrapped in a timely manner.
Packaging and transportation: During the packaging and transportation process, the product should be ensured not to be damaged to avoid affecting the sealing performance. Measures such as shockproof, moisture-proof, and dust-proof can be used to protect the product.
Subsequent processing: For products that require long-term storage or use, some subsequent processing can be performed to improve the sealing performance. For example, apply a layer of sealant to the inside of the aluminum shell, or perform secondary processing on the blister part to enhance its sealing.
To sum up, ensuring that Aluminum Shell Blister Products have good sealing performance requires comprehensive consideration and control from many aspects such as material selection, mold design, molding process, edge treatment, quality inspection, packaging, transportation and subsequent processing.
