Magnetic Billet Heaters

for Non-ferrous Metal Extrusion

50% power savings, 45 sec. heating time,

25% productivity increase, 0 problems

In aluminium, copper and brass extrusion, processing speed and quality depend on the homogeneous distribution of heat within billets. Magnetic Billet Heaters by Zenergy Power and Bültmann achieve better results than conventional induction and gas heating. The magnetic heating process delivers homogeneous radial temperature distribution and precisely reproducible axial temperature tapers in every type of billet. Apart from aluminium, copper and brass, the magnetic billet heater processes magnesium, titanium and inconel as well as spray- and plasma-compacted materials at the push of the button.

• Productivity: increases extrusion speed by up to 45%, facilitates isothermal extrusion;

• Product quality: no overheating, homogeneous material structure, exceptional surface finish;

• Flexibility: no coil change for different billet sizes and materials, rapid part changes;

• Installation: compact  machine, easy-to-install in existing production layouts

• Operating cost: decrease energy cost by up to 50%, minimal maintenance requirement;

• Impact on environment: 50% less power consumption, safe with stricter environmental legislation.

The Magnetic Billet Heater by Zenergy Power and Bültmann has been in industrial operation in the extrusion plant of weseralu GmbH & Co. KG at Minden, Germany, since August 2008.
