furnaces, heat treatment & sand blasting
The following furnaces of our shop are available for series or single orders:
bogie hearth furnace
- is used for the heat treatment of welded parts up to a width of 3 metres and a depth of 6 metres
- asymmetric welded constructions should annealed or stress-relieved before machining
- freshly fired cut sheets can also be stress-relieved
- we can anneal and subsequently cool down demanding parts; e.g. to remove undesired alloy fractions in castings, or to follow given temperature diagrams
- the furnace control technology is digital and allows to follow complex temperature profiles
- a USB hub allows to document, print or send the actual measured values
- diverse temperature sensors in different positions are calibrated to document temperature differences of 0,2°C

top-hat furnace
- is used for the heat treatment of heavy parts up to 40 tons, e.g. mould frames can be interstage annealed or stress-relieved at common temperatures between 500 and 550 °C
top-hat furnace
nitriding furnace
- is used for nitriding parts with lengths up to 2 metres, e. g. components of casting dies, complete shot sleeves or other wearing parts
- special coatings can be burned-in up to 1100 °C, e. g. as wear protection of casting ladles
- is used to stress-relieve extra large parts
- the process is electrical controlled by measuring the vibration amplitude with a sensor
- doesn't cause any scale or structural changes
- is faster and less expensive than heat treatment

walk-in sandblasting system
- we can sandblast heat treated parts to obtain a clean surface
- we can sandblast finished welded constructions and complete machines to obtain an even and reactive surface, e. g. before painting
- we don't sandblast with "sand" but special blasting abrasives
- the chamber is extra large to sandblast even large parts
- the chamber is situated as far as possible from our paint shop to avoid any entrapment of blasting abrasives or dust
- a special compressor unit provides high power compressed air
- the in-house sandblasting system allows short delivery times for our clients
- the large sandblasting system is enhanced by several manual blasting equipments for smaller parts
