DIY Injection Molding - How to Get Started - 3D Insider Get frames to make the mold. The first step in our injection molding setup is to create a mold. We will use epoxy to create our mold. Epoxy is actually a two-part liquid. Setup the model/item in the mold. Once you have your frames in place, proceed with setting up the frames for the mold creation. In order to create a mold, you will need epoxy and the actual item that you are trying to replicate using injection molding. Pour in the epoxy. Now that your mold frame is ready with the item in place, pour in the epoxy. One quart of a two-part epoxy should be enough for a regular sized frame. Leave overnight for epoxy to harden. Now let the epoxy in the first frame harden. That way, you will create one half of your mold. Creating the mold is a two-step process.

Managing parting lines in injection-molded parts - Design ... Aug 24, 2014 · Designing parts for liquid silicone rubber (LSR) molding and metal injection molding (MIM) is similar to thermoplastic molding, though with both of these processes, additional preparation to prevent flash should be considered. LSR flows into the mold as a liquid and will fill into gaps as small as 0.0002 in., which can result in flash. Though parting lines on LSR parts are likely less visible, and less intrusive, they are harder to prevent.
