Each condom passes through an electronic machine to detect holes using a voltage of 2,000 V. To do this, the condom is placed in a cylindrical metal mold which moves so that it makes contact with a rubber band which rubs the condom. If the condom does not have any holes the machine will not detect current, and in this case the condom acts as an insulator, otherwise it will detect current and condom must be rejected because it has a hole.
At the end of this process, the condoms are rolled automatically.
Latex condoms, after having been subjected to rigorous quality controls throughout the manufacturing process, are now ready to be packaged.
