Insert Molding Boss Size Calculator
For insert molding, the plastic boss around a metal insert carries the pull-out and torque load. Too thin and it cracks; too thick and it sinks. Enter your insert diameter to get a working boss range.
Working rule of thumb, not a substitute for mold-flow analysis. Engelhardt confirms boss geometry and runs pull-out tests on your actual resin during sampling.
