Combicore core with metal casing Cut through cast part with Combicore core

Cores for high pressure die casting...

...and other casting processes

Combicore cores consist of a shaped metal shell that is filled with a special material. This enables foundries to create media-carrying channels and other cavities in cast parts, efficiently, quickly, reliably and cost-effectively.

Combicore cores are extremely stable and can also be used in high pressure die casting with over 1000 bar.
After the casting process, the filling is removed. The metal shell remains as a channel in the component.

In this way, highly efficient cooling channels are created, which ensure optimal temperature control of the near-net-shape cast part. Lubrication channels are also typical applications in the automotive sector.

With Combicore, casting cores can be used in high pressure die casting for the first time. Trust in our decades of experience.

Combicore cores: Innovative Benefits

As an innovation, Combicore cores and components from our customers have received multiple awards. Combicore properties offer decisive success criteria:

  • Realization of complex channel structures
    "in one pour"
  • Dimensionally stable at over 1200 bar
  • Ideal for high pressure die casting (HPDC),
    can be used in all casting processes
  • Great freedom of design
  • Optimal temperature control of components
    (Cooling + heating)
  • Leak-free,
    no drilling and no plugs required
  • Reduction of material, efficient lightweight construction
  • Sustainable conservation of resources, also in later operation
  • Easy removal of the filling after the casting process
  • Inexpensive
  • Made in Germany

Metal Forming:
Tube, wire, sheet metal

As a metalworker, we have several 2D and 3D CNC bending machines with which we can also create complex tube geometries. We process materials such as steel, stainless steel and non-ferrous metals.

A wide variety of shapes can be created with tube end forming technology, so that tubes can be connected to the system without leakages. Expensive turned parts or complex welding and soldering work can thus be saved.

Tube end forming: Beading

We also carry out the following work for you:

  • Sawing
  • Deburring
  • Pressing
  • Drilling
  • Turning
  • Milling
  • Annealing / heat treatment
  • Welding
  • Soldering

Strong connections

We assemble bent tubes and profiles into ready-to-assemble end products. Several Combicore cores can also be connected to core packages by welding, soldering or other suitable joining processes.

Cooling element with welded wires

Attached wire bridges, pins and other attachments can facilitate handling in the foundry.
