Thin Walled Part Warping Overcoming by Honeycomb Ribs Design
Thin walled plastic parts are subjected to warpage after injection. Warpage can be overcome by the ribs features. This experimental project is to design a honeycomb ribs replacing the normal ribs to overcome part warping. The parameters included ribs height, the ribs thickness and the honeycomb size...

| Summary: | Thin walled plastic parts are subjected to warpage after injection. Warpage can be overcome by the ribs features. This experimental project is to design a honeycomb ribs replacing the normal ribs to overcome part warping. The parameters included ribs height, the ribs thickness and the honeycomb size. Finite Element Analysis (FEA) simulations for each honeycomb ribs design are analyzed with Autodesk Moldflow Insight software and the part which result the worst warping value, part with medium warping value and part with less warping value were chosen to validate them by fabricating the core and cavity inserts to produce the actual product. The part warping is measured and then compared with the data from the simulation. Thus, the best design parameter of honeycomb ribs is identified. |
