Specifics For Prototype Overmolding

   At Creative Mechanisms, we do prototype overmolding. More often than not, we are overmolding a soft rubber onto a plastic or metal substrate. We typically create plastic molds to hold the substrate in place and then mix polyurethane casting rubbers to be injected into the molds. Once cured, the rubber and substrate are removed as one part. Of note, we can control the hardness and the color of the overmold material. You can watch the process here [EMBED VIDEO]. In mass production, with TPEs, overmolding can be done in 30-60 seconds. However, in prototyping, it takes several hours because we use 2-part casting rubbers that need to cure over time.
