In blow molding, a core rod is utilized to help shape the interior cavity of a hollow plastic part. The process begins with the extrusion of a plastic parison, which is a tube-like piece of plastic. The core rod is then inserted into the parison, and simultaneously, the mold closes around the plastic. Air is blown through the core rod, inflating the parison so it takes the shape of the mold cavity. This method is particularly useful in creating precise internal geometries and allows for high-quality control over the thickness of the walls of the molded part. The use of a core rod can be found in various applications including the manufacturing of bottles, containers, and other hollow items.

Thin film technologies often absorb more energy than bulk silicon due to their unique material properties and structures. Silicon, in its traditional bulk form, has a direct bandgap that is less efficient in absorbing light across the solar spectrum. Thin-film materials, such as cadmium telluride (CdTe) or copper indium gallium selenide (CIGS), are specifically chosen for their excellent light absorption characteristics. These materials can be designed to have a direct bandgap closer to the optimal value for solar absorption, making them more efficient in converting sunlight into electricity per unit of material used. Additionally, thin films can be applied in layers that are just a few micrometers thick, reducing material costs and allowing for flexibility in the application on different surfaces. The structuring of thin films can also enhance light absorption through anti-reflective coatings and light-trapping schemes, further increasing their efficiency over bulk silicon in certain ...
