How are they made...German Craftmanship.
All WOLL professional cast products are cast by hand from high-quality, pre-processed aluminium alloy using a variety of casting processes – without the use of electrical voltages and free of any harmful entrapped air.
After careful grinding and micro-fine trimming, we apply aluminium titanium oxides or diamond crystals to the cookware surfaces using a highly complex procedure involving the use of a 20,000 °C plasma jet. The result is an extremely cut-resistant product.
The products are finished off with a sealing process carried out on our production line – the most modern line for applying such coatings in Europe. It combines the use of cutting-edge high tech with extremely low CO2 emissions. We can proudly say the whole manufacturing process for our ranges of pans, including the application of protective coating, is entirely free of PFOA (perfluorooctanoates).
1 Cast body in pre-processed aluminium alloy.
2 A sandblast treatment increases the surface area by 15 times to ensure the best possible adhesion of later layers.
3 Extremely hard cut resistant base layer: titanium or diamond crystals are bonded to the aluminium using a plasma jet at 20,000 °C/36,000 °F.
4 Unique protective layer against corrosion.
5 The third layer provides the cookware’s long-lasting non-stick effect.
6 The specially developed single or double top layer is reinforced with ceramic, sapphire or diamond particles, ensuring the unique long service life of WOLL products.
