but how to add ribs to a plastic part design, maybe there are something need to be considered:
1) in order to avoid air bubbles and shrinkage cavities. the focus is to minimize the concentration of the material in an areas,
2) Rib should not be too big, they should be short and more in quantity.
3) the distance between ribs should be equal or greater than twice the wall thickness.
Ribs are a feature in plastic injection molded parts. They are thin extensions that run perpendicular from a wall or plane. They are commonly used to provide additional support and strength to a part.
Thickness and location are essential to rib design. Here are some helpful design guidelines:
They should be designed with a thickness that is ½ the wall thickness to avoid a thick section at the wall base
To minimize sink marks, design ribs that are approximately 60% of the joining wall thickness for minimum risk
Best practices include spacing at a distance of at least twice the wall thickness
Glossy materials require a thinner rib (40% of wall thickness)
your experience is very good, please write more:-)
your experience is very useful, I got it, thank you so much!
