Why do plastic parts keep cracking? How to solving stress cracking in engineered compounds?

If your plastic parts keep cracking during use, storage, or even shipping, you’re not alone. Stress cracking is one of the most common and frustrating failures engineers and manufacturers face. Let’s break down why it happens and how you can stop it before it costs you more time and money.

Poor flow, short shots? Here’s how to fix it with the right compound.

If your parts aren’t filling the mold, leaving voids or short shots, don’t blame the mold or the machine just yet. In many cases, the root cause is poor flow behavior from the compound itself.

Using flame-retardant resin but still fails the test? Here's the reason.

You’ve chosen a flame-retardant (FR) plastic, run your parts through testing, but the results still fail. Frustrating, right? You’re not alone. Many customers assume that simply selecting an FR-grade resin guarantees UL94 or other flame resistance certification. Unfortunately, it’s not that simple.
