Performance Advantages of 8011 H18 Aluminum Foil in Pharmaceutical Blisters

One of the most important performance advantages of 8011 H18 Aluminum Foil for Blister Packaging is its high mechanical strength. The fully hard temper reduces the risk of tearing, cracking, or pinholes during high-speed blister forming and sealing processes, improving packaging efficiency and reducing waste. In addition to strength, the alloy delivers excellent barrier protection. Aluminum foil acts as an absolute barrier to gases, water vapor, and light, making 8011 H18 especially suitable for medicines that are sensitive to environmental exposure. This contributes directly to product safety and long-term stability. Surface quality is another critical factor. 8011 H18 aluminum foil has a smooth and uniform surface, allowing for high-quality printing, embossing, and coating. It bonds well with heat-seal lacquers and adhesives, ensuring reliable sealing with PVC, PVDC, PET, or aluminum blister base materials. These combined properties make 8011 H18 aluminum foil highly compatible w...

Process Flow and Future Development of Lost Foam Casting

The Lost Foam Casting process typically begins with the design and fabrication of the foam pattern. Expandable polystyrene is shaped through pre-expansion, steam molding, thermal forming, and finishing to achieve accurate dimensions and a smooth surface. After inspection, multiple foam patterns are assembled into a casting cluster and coated with a high-performance refractory coating. The coating not only enhances shell strength but also helps maintain the outer geometry of the pattern during vaporization, ensuring better surface quality of the final casting. Once the coating dries completely, the cluster is placed inside a sand box, where dry sand is compacted around it through vibration to create a stable supporting mold. During pouring, the foam pattern decomposes under the high temperature, the gases escape through the coating’s permeability, and molten metal fills the cavity to form the part. After solidification, the casting can be removed, cleaned, and processed further as need...

Future challenges and development directions of precision casting

Although China's precision casting output leads the world, it still faces multiple challenges: Technology gap: high-end castings such as aircraft engine blades and nuclear power components rely on imports, and key processes (such as riserless casting) have not yet been broken through; energy consumption is 2-3 times that of developed countries, and large processing allowances lead to material waste. Environmental pressure: Traditional casting produces a large amount of waste sand and waste gas, and the domestic recycling rate is less than 50%, while Germany has achieved 100% recycling. Talent shortage: The casting major in colleges and universities has been cancelled, the industry's attractiveness has declined, and the gap in high-skilled talents restricts innovation. Future development directions include: Intelligent upgrade: Introduce digital twin technology to optimize process parameters, such as the 3D printing sand mold technology developed by Shenzhu, which shorten...

What is Investment Casting?

Investment casting, also known as lost-wax casting, is a centuries-old manufacturing process that has evolved into a highly precise and efficient method for creating complex metal parts. The process begins with the creation of a wax model of the desired component, which is often produced using injection molding or 3D printing for accuracy. This wax model is then coated with a ceramic slurry and refractory materials to form a durable shell. Once the ceramic shell hardens, the wax is melted and drained away, leaving behind a hollow mold. Molten metal is then poured into the mold, filling the cavity and taking the shape of the original wax model. After the metal cools and solidifies, the ceramic shell is broken away, revealing the final metal part. This method is particularly valued for its ability to produce parts with intricate geometries, smooth surfaces, and tight tolerances. It is widely used in industries such as aerospace, automotive, medical, and jewelry, where precision and qual...
