When it comes to plastic part performance, sometimes the smartest reinforcements are the simplest.

We’re always looking for ways to make our plastic components stronger, more reliable, and more cost-effective. One of the simplest yet most powerful design strategies we use is adding ribs to our injection molded parts.

They might seem like small details, but they play a big role in reinforcing the overall structure. By strategically placing ribs, we can significantly increase the stiffness and strength of a part without adding much material or weight.

This is especially important when working with plastics which can flex or warp under load. Ribs help distribute stress more evenly, reduce deformation, and improve the part’s ability to withstand mechanical forces. They also allow us to use thinner walls, which reduces cycle time and material costs, all without compromising durability.

Designing effective ribs is both an art and a science. We consider factors like rib thickness, height, draft angles, and spacing to ensure they enhance performance without causing issues like sink marks or warping during molding.
