THONI-ALUTEC offers 2 casting methods

The sand casting process offers highest flexibility and low tooling cost. We use this process to produce casting weighing up to 10 tonnes and covering a length of over 30 feet. The gravity die casting process is used to produce high quantities and gives also higher strenght. Nevertheless this method has its limits and we currently produce maximum casting wheights of 90 kg. Heavier parts can be produced but this is very much depending on their shape.
Looking at our range of products the expert can easily judge our achievement on the aluminium foundry market. Customers from different industries worldwide see us a reliable and high performing partner. Faraway customers in the U.S., China or India are the best evidence for the high standard of our work and their confidence in us.
Currently there are nearly 2000 sets of tooling in our stores of which our customers order aluminium castings on a regular basis. Having this large variety we must meet each customers demands individually.

At the moment we mainly supply to the following industries.
• Medical
• Robotic
• Energy
• Combustion engines
• Railway
• Mechanical engineering

However, we are constantly engaged in creating new applications for aluminium castings. Running projects to which we supply prototypes open up new interesting business for us in the near future.
Below please find some alloys we use. Should you have a special request for an alloy we are more than happy to fulfill your requirements.
