Welcome Guest!
In previous lessons you learned that using ribs as a design feature can add strength and bending stiffness to molded parts. Now we will introduce corrugation and v-grooves as another design option.
This lesson covers the advantages and disadvantages of using corrugation and v-grooves in a part design, what other factors to consider when using these design elements, the effects of different layouts on fill patterns, and how different corrugation and v-groove layouts impact part flatness.

Goals of Part Design (Level 1):
Section Description:
As plastic part assemblies become more sophisticated, individual part designs become more complex. This complexity can create challenges for part designers, mold designers, and process engineers. Early in the part design phase, designers must establish design parameters, a necessary step for molding high-quality parts that meet specifications and expectations.
This section covers explanations, simulations, cause-and-effect analyses, and the uses of various design features. Understanding these design features is important because they influence a part’s moldability, function, appearance, and quality.
Recommendation: Entry-Level Operators, Technicians, & Designers
Length: Lessons are approximately 15-20 minutes long each
