Micro-Hole Detection System

defect detection for heat exchanger plates

Speed up your production with automated, in-motion micro-hole detection on flat sheets of any size.

How it Works

We combined a multi-camera line scan system, belt conveyor, and simple software to ensure excellent performance and an effortless experience for the operator. As material travels the conveyor, line scan cameras are encoder-triggered to image the surface for defects. The inspection system can detect hole defects down to .015″ in a 12ft sheet in under a minute.

A Challenge Resolved

Faulty heat exchanger plates lead to leakage and are a common HVAC headache. Inspecting heat exchangers by manual methods like dye testing is time-consuming and doesn’t guarantee 100% inspection. We developed our vision system for a company that was searching for a more efficient and non-destructive testing process. Their existing manual procedure required dye testing on parts that were already assembled. Our Micro-Hole Detection System integrated in-line for quick, 100% inspection, and enabled the manufacturers to catch bad parts pre-assembly. The high tech solution also yielded a much more accurate solution than the manual inspection process.
