Current Combicore Issues
With new name into the future
We have decided the change of name from Drahtzug Stein combicore GmbH & Co. KG in TubroTec GmbH & Co. KG and registered it.
In the past we have concentrated ourselves on Consulting, R+D and project management. With the change of name we will take over the production that was realized by a subsidiary company of our partner Drahtzug Stein holding GmbH & Co. KG.
Our Website will be changed in the next weeks....

Stable, filled inlay tubes for foundries
Near end outline casting with remarkable material savings
Foundries make channels for oil, water and other cooling liquids or gases by using combicore cores.
The thin walled tube is stabilized with a filling and therefore resists casting pressures of more than 1,000 bar.
In light metal casting usually a pure salt core without binder and any other chemicals is used. Normally the core casing is a thin-walled aluminium tube.
In heavy metal casting other suitable materials are used.
After the casting process the filling material is removed completely. The metal casing remains in the cast part.
Combicore cores are lost cores.
Typical applications are found in the automotive sector, as for example gear box housings, engine blocks, calipers and cooling elements for electric cars.
The Revolution in High Pressure Die Casting
Combicore foundry cores offer numerous benefits
- Suitable for aluminum pressure casting, magnesium casting and other casting processes;
- Realization of complex geometries;
- Huge scope of design;
- No drilling and no tamping necessary;
- Near end outline casting with remarkable material savings;
- Realization of a consequent lightweight construction possible;
- Other advantages.
