Sliced wafers - Import export

After the surface grinding, the crystal is sliced into wafers with a thickness according to customer’s specifications. Sawing machines with diamond impregnated blade are used for the slicing. We have got 5 sawing machines with a monthly capacity 2500 kg. Maximum diameter Ф152 mm. Wafer thickness up to 80 mm. Slicing accuracy ± 25 microns.

The DW292 is specifically designed for cutting monocrystalline silicon ingots up to 300mm diameter into high quality wafers for the semiconductor industry. The newly developed DW292-300 can be operated with slurry wire, as well as with diamond wire, and has sophisticated features for optimizing warp and ripple. The longer wire field, as well as the higher wire speed and acceleration, enable a higher throughput per machine and year. The use of extremely thin wire is possible thanks to smaller inertia of moving parts, fewer deflection rollers and shorter wire distance. The DW292-300 is highly resistant to temperature fluctuations and vibrations due to its compact and robust machine frame made of mineral casting. Thanks to higher process automation and the new intuitive HMI with dialog-based production wizard, operation is safer, easier and faster.

The company is technologically capable of slicing of thin wafers from optical glass and semi-precious stones.

The meaning of the word “Santoku” – “three virtues”, clearly explains what it is best used for: chopping, dicing and mincing. It handles all of these jobs in exemplary fashion. For this reason, it is one of the most commonly-used knives in both professional and home kitchens. The blade that is thinner than in Chef’s knife allows for wafer-thin slices – as found in many Japanese dishes. Presentation blade size: 16 cm Unlike other kitchen tasks, cutting, chopping, slicing and dicing are still mostly done by hand. While many of us have modernised our kitchens with high-tech toasters, smoothie machines and slow cookers, possibly the most ancient device of all, the knife, remains. Felix has been making knives in Solingen, the "City of Blades", since 1790 and still today stays true to its centuries-old tradition. It takes more than 45 steps to make a perfectly forged Zepter knife out of a high-quality, single piece of steel.
