Today's KNOWLEDGE Share

Poor wall thickness design often creates hidden costs in injection molding — long after the mold is made.

Many product teams focus on appearance and functionality, but wall thickness decisions made early in the design stage can quietly increase costs throughout production.

Here’s what usually happens when wall thickness is not optimized:

• Higher mold cost due to complex tooling and cooling design

• Longer cycle time because thick sections cool slowly

• Warpage, sink marks, and inconsistent part quality

• Increased material consumption with no performance benefit

• Costly mold modifications after tooling is completed

In mass production, even a few extra seconds per cycle or a small increase in material usage can significantly impact total cost.

That's why experienced injection molding suppliers always recommend DFM analysis before tooling — optimizing wall thickness through design, not by adding more material.

Many cost problems don't come from material prices — they come from design decisions made too early.
