Compression molding can offer an efficient way to manufacture strong composite components with complex shapes, good dimensional control and repeatable features.
But its value depends heavily on the application.
Because the process uses matched tooling, it can become particularly attractive when production volumes justify the upfront tooling investment. It can also allow features to be molded directly into the component, potentially reducing machining or secondary operations.
Part size, geometry, material system, surface requirements, tolerances and expected production volume all influence the decision.
For programs moving toward higher production quantities, the economics can look very different than they did during prototyping.
At GP&C, process selection starts with understanding both the component and the production program around it. If you’re evaluating manufacturing options for a new or growing program, talk with our engineers about whether compression molding makes sense.
