Our die casting plant in Cologne specializes in the cold chamber die casting process. Our qualified employees manufacture high-strength components from aluminum alloys for use in the automotive industry.<\/p>\n

The aluminium die casting process impresses with its representation of complex geometries, high dimensional accuracy, good surface quality, low wall thicknesses (weight-optimized) and is ideal for cost-effective series production thanks to the short cycle times.<\/p>\n<\/div><\/div>

<\/div>
    \n
  1. \n

    Melting:
    \n<\/strong>Use of alloys such as AC 46000 or AC 43400 (low copper) at melting temperatures of up to 730 \u00b0C.<\/p>\n<\/li>\n

  2. \n

    Casting:<\/strong>
    \nIntroducing the molten metal into the die casting mold at 680 \u00b0C with a casting pressure of up to 1,000 bar enables low component wall thicknesses, high dimensional accuracy and fast cycle times (75-100 sec.). These are necessary to enable economical series production.<\/p>\n<\/li>\n

  3. \n

    Mold cooling & vacuum:<\/strong>
    \nState-of-the-art vacuum technology and mold cooling systems (spot cooling) are used to achieve the best component quality.<\/p>\n<\/li>\n

  4. \n

    Automated removal<\/strong>:
    \nTrouble-free component handling within the casting cell is achieved by specialized foundry robots.<\/p>\n<\/li>\n

  5. \n

    Quality:<\/strong>
    \nIntegrated X-ray inspection (YXLON\u00ae), computer tomography (CT), tactile and camera-based dimensional accuracy testing and state-of-the-art leak testing guarantee a high component quality standard.<\/p>\n<\/li>\n<\/ol>\n<\/div><\/div>
