The automation of manufacturing and technological processes has significantly accelerated in the 21st century. Nowadays, it is the fastest growing department of electrical engineering, applicable in every field of industry, from the production of large components for cars or household appliances, to the production of the smallest precision devices, integrated circuits, etc. Industrial automation systems consist of devices and machines that carry out production, transport or packaging, control and measuring devices to supervise quality, efficiency and safety in the workplace. These are very often "tailor-made" devices for a given manufacturer using many non-standard parts and components. In case of a failure of mechanical parts we are able to reconstruct the damaged element on its basis or using technical drawings. We are also able to prepare completely new elements for modernization, modification or optimization of the production line.
