RTV and Cast Urethane Models
Many projects require a higher quantity of prototype models, or perhaps a more plastic-like material. Silicone rubber tooling is an excellent, more traditional and cost effective method to consider when these types of projects arise. Depending on part complexity, one RTV tool has the capability of producing as many as 25 cast urethane models. There is a wide array of urethanes from which to choose. Urethanes can be clear, colored, rigid, soft, high-impact or temperature resistant. It is even possible to insert metal components into the cast urethane models. These attributes can lead to a high-quality, semi-functional prototype that more closely simulates your end product. Although not commonplace, our highly skilled team is currently utilizing this technology for the limited production of more than a dozen unique parts.
Our process begins by creating an SLA master model which is highly finished. This pattern is then encapsulated by a thick, liquid silicone rubber. Once cured, the silicone rubber mold is delicately cut open to reveal and extract the SLA master pattern. Urethane is typically used to fill the mold creating a prototype model of your part. This can be done until the mold loses viability, which is dependent upon several factors, including part geometry and type of urethane. The RTV process is truly an art.
