Figure 20 …Designing for Injection Molding - Injection Mold Design - Plastic …Figure 7 is a surface finish guide created by the Plastic Industry Association for use during plastic injection molding. As you can imagine, going up the scale to the “A” surface finish gets more time consuming, and therefore, raises tooling cost. Starting at C-3, each stage on this scale builds on the one before it.



Cosmetic Appearance on Injection-Molded Plastic Parts

Part geometry can affect many aspects of cosmetics. There are so many possible geometries it’s impossible to provide a comprehensive recipe for good cosmetic results. Following the usual rules 2 for good injection-molded part design will usually improve the cosmetics of the part, and violating those rules often leads to cosmetic issues. It ...
