We call our K1 technology a
worldwide unique casting process

The K1 system consists of the subsystems INCAST, INHEAT, INVAQ and INCONTROL. Working together, they enable a casting process in which the shot sleeve is hermetically sealed by a counter piston on the die side, with the melt dosing being initiated via the suction pipe solely by the vacuum modules on the shot sleeve. This completely eliminates the need for vacuum seals on the die side.

Technological advantages

Cast part

  • Extremely fine and homogeneously distributed grain structure

  • Highest mechanical strength characteristics already in the cast state

  • Unrestricted heat treatment with extremely short homogenization times regardless of geometry and alloy due to oxide and gas-free structure

  • Unrestricted weldability with all common welding processes
  • Coating with baking temperatures > 400 °C possible




  • Most complex component geometries possible with multiple slides in 2 and 3 platen dies

  • Unrestricted use of all castable Aluminium primary and secondary alloys

  • No vacuum seals required in the die

  • Highest effective vacuum (< 100 mbar) during the dosing process

  • Dosing rate up to 7.5 kg/s can be achieved

Customer benefit

Flexibility in application

The K1 technology is characterized by maximum flexibility, i.e. the K1 systems can be connected to existing die casting machines.

Reducing scrap rates

With the K1 technology, the casting quality in the die casting process is significantly increased. By dosing the melt without contact to the atmosphere, the melt is free of gases and oxides.

Growth, aquire new markets

By using K1 technology, our customers have the opportunity to open up new markets in lightweight construction.

Safety components that previously could not be produced using die casting can be manufactured with extremely reduced weight due to the material performance using K1 technology.

Furthermore, our customers can expand their parts portfolio and offer weldable die cast parts with material properties equal to forging.

Improve the CO2 Balance

Using K1 technology, castings are manufactured in an extremely resource-saving, material-saving and energy-efficient manner, which significantly improves our customers' CO2 footprint.
