Precision work

to melt your heart

Founded in 1993, ZPF quickly established itself in the greater German-speaking area as a supplier of high-quality aluminum melting systems. The economy of its melting assemblies, both for fuel as well as for the raw material aluminum, drew global interest. Following a temporary expansion to Asia, the company re-established itself as ZPF GmbH and began producing its melting furnaces for the aluminum industry exclusively at the Siegelsbach location again.

 

In 2022, the pioneer and die casting specialist FRECH acquired operations of ZPF GmbH. With the newly founded FRECH ZPF GmbH, headquartered in Schorndorf and with a production location in Siegelsbach, the corporate group has expanded its field of business and now sets the standards for sustainability, energy efficiency and environmental compatibility with innovative technologies in aluminum melting systems.

Partnership

in research and innovation

Every melting assembly from FRECH ZPF receives a thick core made of a fireproof special material. This material serves not only as an isolating layer between the aggressive liquid aluminum and the outer steel casing, but particularly also as insulation and thermal storage. While other melting systems radiate temperatures of more than 100 degrees Celsius to the surroundings, here it's only 40 to 60 degrees Celsius. The fact that less heat is lost as a result reduces the overall thermal energy demand and makes working on the melting systems significantly more comfortable.

 

Research and development play a crucial role in achieving this kind of efficiency. Our engineers are constantly working on new ideas in close cooperation with development partners to make the assemblies more durable, efficient and user-friendly. Innovations that receive priority are predominantly in the areas of corrosion-resistant substances for fireproof materials, alternative burner concepts, thermal recovery for increasing energy efficiency and raw material recycling.

Hot Commodity

Aluminum

The heart of FRECH ZPF technology is the reversed exhaust gas routing. Hot gases are not immediately conducted into the flue but rather into the furnace interior. Here, they help to keep the melt hot, which saves thermal energy and increases the efficiency of the systems. At the same time, any pollutants in the flue gases are nearly completely incinerated. As a result, the cleaned exhaust can be released into the environment without additional filtration.

 

This specialized exhaust principle of the melting systems also has effect on the quality of the melted aluminum. Because the introduced gases generate a slight positive pressure in the interior, no additional oxygen can penetrate. This prevents undesired oxidation of the aluminum and minimizes corundum formation. A positive side benefit of this method is that the furnace walls are damaged less over time and must be re-lined less often as a result. This not only extends service life, but also protects important raw material resources.
