Once you understand the geometry of your part, as well as its intended purpose, tolerances, and surface finish, you’ll want to think about which material you’re going to use. This will determine the melting temperature, shrinkage rate, and flow characteristics, among other things. Once all that’s done, CAD software is usually used to create the design and simulate things like the flow and solidification of the molten metal. You typically have complete control over a design within CAD software, and that will allow you to foresee any potential issues, and fix them before you even begin manufacturing.
Many of our customers who design molds using CAD software will carefully plan and include a gating system and a cooling system to keep the flow intact and free from gases, as well as regulate the temperature and allow the part to cool and solidify quickly. By taking their time with these steps, professionals can create molds that will stand the test of time and endure all sorts of use.
