    Fettling Shop

    The company continues to invest in new tools and equipment required in order to provide high quality of welding processes and heat treatment. These processes also ensure significant reduction of scrap rates and optimize acquisition costs.


    Fettling Technologies:

    • shot-blasting systems
    • heat-treatment furnaces
    • tempering furnaces
    • argon, plasma and carbon welding
    MAGMA SIMULATION
    In addition to the standard CAD/CAM solutions CKD uses casting simulation software for technology development, enabling to verify and evaluate the entire casting production process in terms of quality, engineering design and internal homogeneity. It helps us to save time and costs for launching of the new products and contributes to the achievement of lean efficiency in serial production.
    MACHINING SHOP
    Our machining technologies are featured by the numerous advantages: they enable us to produce rather complicated outputs, because many customers order completely machined products. Another advantage is a cutting-edge Paint Shop and welding equipment. We have profound experience in assembly of complicated and certified products. In addition to KH Machining Shop we have also a machining facility in Chrudim.
    Sheet-cutting equipment; laser and acetylene.
