Designing For Moldability & Manufacturability

What’s The Difference Between Moldability and Manufacturability?

Though subtle, the differences between moldability and manufacturability can have an impact when designing parts for the plastic injection molding process. In this post we will explain the differences and provide resources for following injection molding best practices.

What is Moldability?

moldabilityMoldability refers to how well the mold of your part will conform to being injected with molten plastic. Once your mold has been created from your design, a good injection molding process needs to account for how well plastic can fill that mold cavity.  From material selection to mold complexity, there are many factors that will determine whether the part you designed is capable of accepting this process.  Certain features in your part design like undercuts and threading, can be tricky to mold correctly and consistently.   These can cause problems like knit lines, warp and flash.
