The Poka-Yoke systems developed by KVL Comp. can be easily and dynamically adapted to the existing manufacturing system. On developing the modules of the system, we take into account the needs of automotive factories, suppliers of the automotive industry and enterprises operating in other fields of the industry. The elements of the system are designed to work in industrial environment; they are durable and require hardly any maintenance. On designing the system we were striving to develop devices, that are easy to assemble. Their operation and maintenance does not require special skills, their building blocks are cheap and easy to purchase. Here are the different systems that KVL Comp. has proposed already.
