Electronic testing machines for condom production
How to make sure each condom are safe to use? it’s impossible to test each in the Lab, so we must use the electronic testing line. The dry condoms are later inspected visually, and then 100% electronically tested (see description of Electronic Testing Machine) in a high voltage pin-hole testing machine. The testing principle is based on the following : The condom is pulled manually over a metal mandrel and rotated against a counter-rotating contoured test conductive rubber brush. A high voltage current is applied between the mandrel and the test rubber brush. A condom, having pin-hole will allow electricity to pass from the mandrel to the rubber brush and hence register it as a ‘reject’ and is collected in a separate container. The good condoms are rolled automatically and sent for final packaging into the next process.
