Uniform Wall Thickness: The Single Most Important Rule in Injection Molded Part Design
When discussing injection molded part design, engineers often focus on: All of these factors influence the final product. However, if there is one design principle that has a greater impact on molding success than almost any other, it is this: Maintain uniform wall thickness. In practice, many molding defects—including sink marks, warpage, voids, dimensional variation, […]
Solving Wall Thickness Problems Before They Become Molding Problems
During DFM reviews, wall thickness is one of the first things we evaluate. It is also one of the areas where we find the most preventable design issues. Many plastic parts look perfectly reasonable in CAD. The geometry may satisfy functional requirements, fit within the assembly, and meet cosmetic expectations. However, once the part moves […]
