Metal Spreader Rolls

From design to production, Mario Cotta guarantees the highest quality standards.
The whole process is followed by a Technical Office and a highly specialized team of technicians who entirely designs the best solution for customer application in 3D. Taking advantage of high-tech machinery, balancing machine for balancing all sectors, Mitutoyo for tolerance control, Mario Cotta therefore ensures only high quality components and raw materials. All completed rollers are then tested at high speed on our Test Machine, which can accommodate rollers up to 9 meters of table. The test returns fundamental values ​​to guarantee high quality to the product. Vibrations, critical speeds and operating temperatures are measured along the entire board. Only after this fundamental test can the roller be prepared for shipping to the customer.
