Ribbon casting is a process used by companies to create dense and flexible ceramics for industrial use. A slurry mix is poured onto a conveyor belt and passed through an oven, producing ceramic tape with various properties. The process can be monitored remotely for safety. Companies with strip casting facilities may also produce other ceramic components. Material tests ensure products meet standards.
Ribbon casting is a process of materials used by companies to create dense and flexible types of ceramics for use in the production of products such as capacitors. This technique requires special equipment and advanced chemical skills to make the tape composition fit the need. Companies can produce ceramic tape for internal use or can produce it to order to meet the needs of industrial customers. Such products are not generally available for retail sale, as the uses of ceramic tapes are primarily industrial in nature.
The first step in tape casting involves creating a slurry mix. The slurry contains ceramic particles, polymers to plasticize the final product, and fluid. It is poured onto a polymer-backed conveyor belt that runs through an oven. As the fluid passes through the furnace, it evaporates, leaving a solid ceramic material. The coils on the other side can wrap around the ceramic tape as it emerges.
This process can generate ceramic materials in a variety of widths, with an assortment of properties. Strip casting is a highly flexible process, as companies can easily tailor the slurry for different projects, as long as a chemist can accurately calculate the needs of a given application. The finished ceramic tape is very heavy, but the wrap makes it easy to move. It can be lifted on forklifts or packaged in drums and rolled, as required.
Staff oversee the tape casting process to ensure it goes as planned. They can monitor the speed of the conveyor and make sure the oven is running at the proper temperature. These tasks can often be performed remotely, allowing personnel to stay out of the equipment area. This contributes to safety by eliminating exposure to fumes and potentially dangerous moving parts. While on the ground, it may be necessary to wear face coverings and hearing protection to reduce the risk of injury.
A company with strip casting facilities may also be able to handle other ceramic molding and casting businesses and often has a product line. For example, it can also make ceramic resistors and other components for electrical and IT equipment. Material tests confirm that all products meet basic standards, and the company will print their origin and evaluation information on its finished ceramic products. It is important to select ceramics with the right capability ratings for your application to reduce the risk of injury and other problems.
