Spin Casting: The Basics
Rapid prototyping was brought to a new edge of the tooling production effectiveness by a technology called spin casting. New incredible options were offered to those, who use rapid prototyping by a spin casting that helps to create molds from different types of materials especially metals. Whereas models created by means of spin casting can be very fragile sometimes, parts of real objects can be produced by means of rapid prototyping instead. The term, which is generally defined for the creation of prototyping model can be shortened much with the help of spin casting, so that the model of a product used for testing can be produced in several hours. Spin casting has even more advantages – if a model is created using this technology, it requires no additional tooling or carving, which considerably reduces postproduction expenses. Spin casting technology helps to take into consideration all requirement of a client to specifications and features of a model.
Another subtype of spin casting technology called metal spin casting makes it possible to combine and to use different types of metals in order to get more functional, solid model, done according to all specifications of a standard prototyping model. The functionality of metal spin casting model is undeniable. However the process of spin casting has its own peculiarities among which is usage of special rubber molds in the process of model production. According to peculiarities of rubber mold, a new metal model is created with adherence to manufacturing techniques. Zinc alloys are generally used in the process of spin casting modeling, as they make it possible to use any metal for creation of the outer layer of a model. Any possible metal, for example, steel, aluminum and copper can be replaced by zinc alloys. Different spheres and technologies can use spin casting models. Among them is electroplating.
Of course, there is a wide range of materials that can be used in spin casting, not only metals or metal alloys. Such materials are epoxy, polyurethane, casting wax and casting polyester. Mixing of materials is generally accepted in spin casting technology. Comparing to other rapid prototyping techniques, spin casting is considered to be the most effective and reliable technology, having a number of advantages. One of such pluses of spin casting production is reduced production costs of the technology. The number of items that can be produced with the help of spin casting is unlimited. Other prototyping technologies are quite expensive when it comes to the production of a small number of models, whereas spin casting and metal spin casting can be used for production of a great number of prototyping models, but for a lower price. So, as it has already been mentioned spin casting is not only a time consuming technology, but it also helps to reduce costs on production of prototyping model.
Over the recent decades rapid prototype services coped up with solving lots of tech problems. And rapid prototype might help you to. Please learn more about the rapid prototype industry and how it helps.
