Despite best efforts by injection molders, quality problems will arise and parts will fail to meet spec. The failure may be due to an oversight in first article inspection; worn or aging tooling; or a change in molding suppliers. To fix the problem, you need to determine the true root cause. With Cross-Sectional Scanning, you can easily pinpoint the problem, detect the root cause and make the repair.
Conventional inspection technologies only provide part of the picture. Without complete information, it may be impossible to determine cause and effect. And this can lead to costly, time consuming conclusions that do not address the real problem. Cross-Sectional Scanning is different. It produces inspection data that completely describes the part. Able to scan most complex molded parts, this technology lets you see all features, both inside and out.
An ultra-dense point cloud is the basis for a powerful, visual tool that directs your attention to potential trouble spots. Color mapping produces a 3D image of a part and highlights out of spec features in reds, oranges, cyans and blues. Focusing analysis on what is out of spec eliminates an investment of time in inspection of what is in spec. This expedites the process, provides an accurate picture of the problem, and lets you respond with a correct solution.
In just seconds, color mapping shows deviation from either the original design data or archived data from first article inspection. And since Cross-Sectional Scanning captures internal and external features, the color map can be cross-sectioned to highlight faults within a part. Identifying the real problem eliminates assumptions and lets you determine the root cause.
One company reports that a CMM inspection of a precise molded part lead to an erroneous conclusion that the injection mold needed to be rebuilt. Luckily, this company opted to use Cross-Sectional Scanning to inspect the problematic assembly. The color map function clearly showed that there was no problem with the mold. Instead, the problem was with the molding process settings. A simple process change, rather than a new tool, saved this company $75,000 and avoided a two month delay in product launch.
Manufacturing is rife with variables, some controllable and others unpredictable. These variables will yield parts that fail inspection. Instead of diagnosing the problem with incomplete information, apply Cross]Sectional Scanning and color mapping to detect the root cause and determine the best plan for repair.
