Finding holes or defects in a plastic moulding can be difficult, time consuming and have severe consequences if problems aren’t detected.
Electrical Leak Detection using the Tantec LeakTEC system is an automated, inline 100% inspection system capable of finding micron sized holes in less than a second over an array of parts.
Unlike gas leak detection, pressure decay or other leak detection systems, electrical leak detection is looking for an electrical signal with very sensitive equipment. Because it’s looking for a specific signal and not measuring something over time, the entire test is quick. Often measurable in milliseconds.
Using LeakTEC to detect pin holes in mouldings is commonly restricted to polymers, or least to non-conductive materials.
It is a standard procedure to surface test moulding defects, it can also be used for bonded and sealed sections. This is ideal for a range of applications such as medical devices, caps and closures; indeed, any item where the contained product will spoil when exposed to atmosphere.
