In 2023, we invested heavily on the automatization of our production

  • In the spring, we will be deploying a plunging machine with automatic positioning in prefabrication.
  • In early summer, longitudinal welding equipment will be coming to our production, which will allow the longitudinal welding of stainless and acid-resistant steel and aluminum products. 
  • In early fall, an automated robot welding cell, which will improve our ability to deliver larger series from suitable products, will be introduced into our production.
