Here are some urethane casting FAQs to help you learn more about the process, uses, and finishes.
Q: What kind of vowin.cn/' target='_blank'>molds are used in urethane casting?
A: Our typical molds are made from silicone and made in two parts, a core and cavity, just like injection mold tooling. We create a 3D printed master pattern (or use provided masters) then create the mold by pouring the silicone around the master after setup, which includes creating parting lines and venting and gating schemes. Depending on requirements, we can also produce tooling with urethane, aluminum, ren board, or even 3D printing.
Q: How many parts do you guarantee?
A: Twenty-five parts per mold per cavity is standard. Again, everything is material and geometry dependent, so more or fewer parts are possible. If a project is going to be a repeat production project, volumes per mold cavity can get higher if geometries, material, and tolerancing are standard.
Q: Can you create multi-cavity molds or family molds?
A: Just like injection molding, we can make multiple cavities of the same part in the same mold, or we can put multiple parts in the same mold. This allows us to set up, pour the parts, and demold all the parts at the same time using the same material. This is a good option for production or quick-turn prototypes.
Q: Can you use urethane castings for production?
A: Yes, 50% of our urethane casting projects end up as end-use parts, bridge production, or final repeat production. Urethane is a great option when building up product demand before spending big bucks on injection mold tooling.
