Solutions for efficient light weight designs - Combicore Cores for Foundries

New technologies ask for new cooling concepts and a consequent light-weight construction. With the filled and therefore highly stable combicore inlay tubes it is possible for foundries to make oil, water or cooling channels in different cast pieces.

Such complex channels are not realizable with conventional methods (sliders, drilling, empty tubes). Combicore is an approved method for aluminium high pressure die casting.

Typical fields of application are in the automotive industry (e.g. engine blocks, transmission).

Even very thin-walled aluminum tubes can be molded and adjusted to the cast alloys used. The filled Combicore inlay tubes of aluminum keep their shape even at a high casting pressure of more than 1000 bar. Combicore inlay tubes stood the test in practice at best and are also environmentally friendly and save resources.

Stable, universal usage: Adapted Cores for all Processes

Attractive and innovative applications are practicable in the fields of sand, chill-mold and pressure casting. Though the filled Combicore inlay tubes keep their shape also at a casting pressure of more than 1000 bar.

The core casing is adapted to the alloy melt and provides an optimal coefficient of thermal expansion and at the same time a minimal corrosion potential.

The core casing is either fused, partially melted or molded depending on the selected casting parameters (e.g. temperature, casting pressure, flow velocity) and alloy matching (melt / core casing).

Lost Cores with Metal Casing

Combicore cores are optimally adjusted for the melting process. The tube represents the outer cladding of the cast core. It remains in the cast piece after founding and also represents the needed hollow space.

The following aluminum alloys are commonly used:

  • AlMn1 (EN-AW 3103)
  • Al99,5 (EN-AW 1050)
  • AlSiMg0,5 (EN-AW 6060)
