Fine-tuning screws and formulations can help to avoid premature wear and reduce energy consumption. This increases the efficiency of your equipment as well as extending its lifetime.

extruserve provides you with outstanding screw designs:

• Twin screws are made either from highly wear-resistant nitriding steel or a special stainless steel for chemically aggressive formulations
• For optimum wear resistance, the screw surface is nitrided with special coatings (e.g. molybdenum or chromium, etc.) on the outer diameter or, if required, hardfaced on the flight tips
