Since the company’s founding by Frank Drache in 1984, Drache GmbH has been manufacturing a wide range of innovative products and equipment for foundry technology.

Ceramic foam filters for steel and iron castings
For foundries doing steel, super-alloy or iron castings, either for large components or small to mid-size pieces, Drache believe they have the right ceramic foam filters to achieve optimum results.

Drache’s focus in the area of steel and iron casting is on ceramic foam filters. The focus is on the Cerazirk LD and Cerazirk ZrO2 filters, which are used in all kinds of steel castings, superalloy castings, and large cast iron.

Drache, however, also manufactures Cerasic® NG ceramic foam filters, which are used in iron casting for smaller and medium- sized piece weights. Moreover, the company also offers the implementation of solidification and mould filling simulation as a service.

In excellent shape: Solutions for aluminium foundries
In the field of aluminium casting, Drache provides numerous products for its customers, such as ceramic foam filters, special components for low-pressure die casting, as well as a crucible furnace developed in-house that is used all around the globe.

The filter of choice for aluminium foundries is the Cerapor® LDNG ceramic foam filter, which can be used for sand casting and permanent mould casting.

In addition, there are specific components made of the engineering ceramics Silicon Nitride (SN) and Aluminium Titanate (ATi), which show their advantages, particularly in low-pressure die casting (LPDC). Drache also manufactures its own crucible furnace for aluminium foundries, which offers extremely high-energy efficiency.
