Stop Your Interior Parts From Warping

Ever pull a part out of the mold only to watch it slowly twist and bend right in front of you? It’s frustrating. That “spring-back” happens because the material is still fighting itself—internal stresses that never got smoothed out during heating. Most people try to fix this with bulk heating, but that’s where the trouble starts.

The problem with “even” heating

Here’s the thing: in a complex car part, “even heating” is basically a fairy tale. You’ve got thin walls that overheat in seconds while the thick ribs are still cold in the middle. That’s why we use zonal infrared (IR) control. Instead of one giant heat source, we use partitioned banks. You can tweak the wattage and the distance for each specific area. The goal is to get the whole part to that sweet spot—the glass transition temperature—at the exact same time. No hot spots, no cold spots, and no warping once the part hits the air.

Ever pull a piece out of the mold and watch it slowly shift or pop out of shape right in front of you? It’s frustrating. That “spring-back” usually happens because the plastic didn’t heat up evenly or it cooled down way too fast. You’ve basically trapped a bunch of stress inside the material, and the second it’s free, it tries to fight its way back to its original shape. We’ve found a way to stop that fight using zoned infrared (IR) emitters.
