2018年12月17日 · The Reinforcing Rib structure design on the plastic. The effect of Reinforcing Rib can not only improve the strength and stiffness of plastic products, reduce the distortion phenomenon, but also make plastic molding easy to fill the cavity. As is shown below. 1.1. The design principle of the Reinforcing Rib

2017年7月27日 · Rounded reinforcing ribs are easier to mold, but rectangular ribs provide more stiffness for the same amount of plastic that’s used. This shape-based strength differential is due to the perpendicular positioning of the rectangular rib’s depth. Finally, the side walls of a reinforcing rib need tapers to improve their mold release.
