Prototype molding components
- Concepts like parting line, direction of pull, sprues, runners, and vents are important to understand in the complexity of molding. It will help with your design to consider some of the mold physics. We've talked about the parting line a bit in previous chapters. To review, it's this surface that meets that flesh between the mold parts. On a cast component, the parting line is the sometimes visible line where the two mold halves meet. In many cases, the parting line is plainer and flat, though sometimes it could fall along a curve due to design constraints. The direction of pull is perpendicular to the parting line, so let's look closer. If your parting line splits your part in half like this, along the plane, then your direction of pull is straight up and down. That parting line is important to one of the most important aspects of molding, which is draft. Draft is the angle of taper away from perpendicular, measured in degrees. When your material is cooled, it needs to be ejected…
