Making Movie Magic With Polyurethane Resin Casting

Action movies contain fight scenes. Scenes in which two characters or armies square off. Scenes in which blood is spilled, guns are shot, and swords are swung. But those guns and swords also have to be carried by the actors during the scenes in which there is no fictional combat going on. To make such props, polyurethane resin casting California is done.

Casting is how many props get made. Many visual effects studios employ builders and prop masters who all use the process. But making movie magic is not all the process is used for.

The process itself is fairly straightforward. First, mix two chemicals together, typically in a ratio of one to one, to make the actual resin. Then pour the results into a mould. Depending on what was used to make the mixture, the waiting time for the resin to cure, that is harden, can take between half an hour to a full hour or even more. Once it is cured, all that is left to be done is the remove it from the mould, though this will damage the mould. A protective spray can extend the lifespan of a mould, but it will break eventually.

The process can be done anywhere. All that is needed is the space to do so and the materials, which are readily available. But there are places in which it is done more than others for professional reasons. Any state which has a high number of motion picture or theatrical productions is going to have a proportionately high number of prop masters creating the tools which make such productions more exciting.

Artists are among those who employ the process. While not the most popular method of sculpting, bits and pieces of a larger project can be made with the process. More complex pieces may require multiple moulds.

The spectacle of a film necessitates false weaponry. In science fiction, this weaponry can be something as simple as a toy gun from a department store given a coat of paint to make it look more tactical. In a fantasy setting, blunted swords are usually employed. But in a modern, real world setting, modern guns are used. But modern guns are heavy, and while they have to be used in some scenes, in others, they can be switched out for a lighter resin replica to make it easier on the actors.

But onscreen weapons are not all that is made with the process. The costumes, or at least pieces, can be made through casting as well, especially for armor. In real life, armor is heavy, weighing between eighty to a hundred pounds. Since actors will not be going into actual combat, actual armor is not necessary, so prop armor can be substituted.

But movie fans like to collect replicas and other merchandise from the movies. Action figures and replica weapons are made through the process. The results are then sold to fans for a premium.

Blockbusters need to spectacular. Audiences have come to expect it. But while CGI may provide most of the spectacle, the practical effects do leave an impact on the audience.
