A Guide to Polymer Casts

Creating solutions to solve problems or do things better in any area of life is the order. Art and many other industries make use of different polymers to help in creating these solutions. Different uses of polymers are realized when polymers are subjected to different industrial processes that bring out their different properties. Taking silicone rubber, for instance, it withstands harshest of weather conditions and will be generally stable across temperature changes. Being also resistant to chemicals, radiation and electricity makes it qualify for many industrial uses. Casting processes is the basis of many industries that deal with polymers. However, the process will require temporary molds that get produced from master patterns or part of it. Most prototypes will be made through this process. If the main material making the products is not ideal for rapid prototyping, polyurethane casting is applied instead.

The fact that urethane is exceptional in matching the properties of products being used in making a product and cost-effective at the same time makes it ideal for prototyping. A lot of the mass-produced products come in different parts that are then assembled. Manufacturers can put urethane to use in this process where parts can be duplicated at amazing precision regardless of the quantity. Working with the mold is pretty easy because in that state its very flexible and it allows for capturing of all curves and dimensions of what is being cast. This is what makes the duplicated parts free of any error.

The mold that is used in the castings has been produced with room temperature vulcanized a silicone as well. The master pattern from which the mold is made is produced from a number of processes. Depending on the pros of different methods, each industry will use the most fitting method. Lithography, however, is the most common of all the methods. Lithography is an additional process where ultraviolet resin, which is a photopolymer is used with ultraviolet lasers to cast three-dimension prototypes.

The lithography will see to it that the master pattern features the properties required for its end use, room temperature vulcanized silicone gets added at this point. The master pattern needs to be suspended as the silicone is being added. The master pattern has to be well encased and then left to cure before it is then cut and the master pattern removed. Casts can be made into anything depending on the industry. After prototyping processes is complete, tests should be done on the main material and not the prototype because that is what will be more relevant. Aside from marketing, the prototypes will be used in product descriptions as well. This is very economical.
