If you have a project that requires unique components, investment castings may be the way to go. With a high degree of design flexibility, investing castings offer applications for an array of industries. But, how do you make investment castings? One popular method is a gravity fed process.
Investment castings are an age-old practice that continues to evolve and produce even better products. Investment castings involve a unique mold which workers use for a series of coating and hardening. This allows for remarkable surfaces that are unique and workers can easily recreate. Castings can be made with an array of materials, including heat-resistant options.
A gravity casting is fairly self-explanatory. Simply because gravity is used to fill the mold from a vertical position rather than gas pressure or a vacuum process. But, the process starts with a preheated mold. This helps the material to flow easily and reduce damage to the casting. Then, workers or a machine coats the mold to prevent the material from sticking. The material is then invested, or poured, hardened and removed. There is no need to apply extra force. This is repeated until the order fulfilled.
A typical purpose of gravity fed castings is large production orders. This makes it easy to repeat the molding process for several castings. It also offers less trapped gas within the mold, giving it more integrity. However, workers determine the best process to use for a casting depending on the goal of the component.
