Are you having trouble with the prototyping of rubber parts? We can manufacture them in your desired shape and hardness, starting from just one piece.
For rubber prototypes, the vacuum casting method is the best. If you want to produce a few pieces to evaluate their shape and function (mainly hardness), what manufacturing method would you use? Generally, methods like additive manufacturing or machining are considered, but while additive manufacturing can achieve the desired shape, it limits hardness. On the other hand, machining does not have hardness limitations, but because the material is soft, it cannot reproduce complex shapes. I believe you have experienced the frustration of having to compromise on one aspect to achieve another. In such cases, the method we recommend is vacuum casting. The master model is inverted into silicone, and a rubber-based resin is injected. Since the shape of the master model can be perfectly inverted into the silicone, it allows for the production of flawless replicas. Additionally, because both the mold and the product are soft, minor undercuts can be managed without the need for additional components.

basic information
The process of vacuum casting involves the following steps: 1. Create a master model of the desired shape. (The master model can be made using a molding method or with general-purpose plastics like ABS.) 2. Pour silicone into the created master model to make a mold. 3. Pour urethane rubber into the created silicone mold, wait for it to cure, and then remove the replicated product. This is the general flow of the process.
