Combicore cores: Innovative Benefits

Channels are realized in cast parts with Combicore. Typical automotive applications are heat sinks, cooling plates, battery housings, DC / DC converters, electric motors, ...

Combicore core in different geometries

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

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.

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 1200 bar. After the casting process, the filling is removed. The metal shell remains as a channel in the component.

Central characteristics
Alloys: AlMn1 / EN AW 3103, AlMgSi0,5 / EN AW 6060, Al99,5 / EN AW 1050, CW021A / CU-HCP / 2.0070, CW024A / CU-DHP / 2.0090, E195, E235, 1.4301, etc.
Channel-Ø: from 0,5 mm
Wall thickness tube: from 0,5 mm
Channel length: several meters possible

The Combicore technology creates highly efficient cooling channels, 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 are used in high pressure die casting for the first time.
Trust in our decades of experience.

Awards, recognitions and prizes

In recent years, the Combicore technology has received several awards and has been recognized as innovative and particularly sustainable. We present a small selection of our most important "achievements" here.

Industry award

Combicore has been awarded the industry prize four times in a row. We are Best of in the categories Automotive and supplier. Our innovative core solution for foundries convinced the top-class jury of experts. Our technology is of very high technical, economic, ecological and social benefit.
We see the award as confirmation of our conviction that we work in a solution-oriented manner and thus meet the demands of our customers, namely to always be one step ahead.

We have not participated since award winners were asked to plan an advertising budget.

Industrial Award

International High Pressure Die Casting Contest

The heat sink for a cooling plate in hybrid technology from the Moneva foundry received special recognition. The jury from research and science praised the strong innovative strength and high demands in casting technology.

The die-cast insert is an important pioneer for the use of hybrid drives, according to the jury. Sophisticated cooling technology solves problems in battery technology. The product-safe cast aluminum cooling tube in a secondary aluminum alloy is important for the recognition. The substitution of the multi-part sheet metal construction leads to significant cost savings.

The heat sink accommodates the lithium-ion cells and ensures that the temperature of the battery pack is even.

HPDC cooling element

That was in 2012. We are particularly proud of this award and with this application we were among the first automotive suppliers for new technologies in electromobility.

Innovation Champion & material efficiency award

The German Material Efficiency Prize was awarded to us by the Federal Ministry of Economics and Technology (BMWi) in Berlin in 2010. Since then we have continuously developed our technology. Even then, people recognized our creative and innovative ideas in the field of foundry technology.

"Those who produce efficiently win!" Emphasized Jochen Homann, State Secretary in the BMWi. Material efficiency pays off after a short time. With intelligent solutions, raw and operational materials can be saved in the long term. "That creates clear competitive advantages," says Homann.

Germany material efficiency awards

In the same year we prevailed against 420 applicants from 23 countries and were named Innovation Champion by the Network of Automotive Excellence (NoAE).
