For Injection Mold Engineers

Your Mold Has a Hot Spot.
We Can Kill It.

Gate burn marks on PETG. Warpage on thin walls. Cycle times that won't come down no matter what you try. These are cooling problems — and straight-drilled channels can't fix them. Conformal cooling can.

Sound Familiar?

These Are Cooling Problems. Not Material Problems.

Most engineers try changing materials, adjusting packing pressure, or tweaking gate design. But if the root cause is a hot spot your channels can't reach — none of that will fix it.

🔥
Gate Burn Marks
Especially on PETG, PS, and transparent parts. The gate area stays too hot because conventional channels can't get close enough.
↩️
Warpage & Sink Marks
One side of the part cools faster than the other. Differential shrinkage causes warping that tolerances and flatness specs can't absorb.
⏱️
Cycle Time Won't Come Down
You've optimized everything else. But cooling time is still 20–40+ seconds because one hot zone is holding the whole cycle hostage.
🏭
Low Cavity Utilization
Multi-cavity mold but cavity-to-cavity temperature variation means you have to run conservative settings across all cavities.
The Solution

Cooling Channels That Follow Your Part — Not Just a Straight Line

Conventional channels are limited to straight-drilled holes. Complex geometry means some surfaces are 15–30mm from the nearest channel — and those areas become hot spots.

Conformal cooling channels are 3D-printed. They follow the part contour at a constant 2–5mm distance. Every point on the mold surface is equidistant from a cooling channel.

  • Temperature uniformity: ±2°C vs ±6°C conventional
  • Deep cavities, thin walls, complex features — all cooled uniformly
  • Compatible with hot runner systems
  • Designed in NX / SolidWorks. Validated with Moldex3D before printing.
