Ten years ago, PCV group received a challenge from one of our customers: design a small, inexpensive but reliable gearbox with a 500:1 gear ratio. The gearbox was meant to be part of a handheld beauty device, so it would be mass-produced and used by a consumer which means no regular maintenance or lubrication. This kind of challenge was well suited for Dries Nijsen, a creative mechanical engineer and co-founder of PCV Group.
