Sarclad - Model Rolltex MSA - Multi Servo Array for Automotive Panel Roll Texturing

SHARE
The Rolltex Multi Servo Array (MSA) from Sarclad is an advanced Electro-Discharge Texturing (EDT) solution. Catering to surface critical strip applications, such as automotive external panels, the MSA ensures precise roll texture control. A significant advancement over standard EDT technology, the MSA features customizable electrode arrays, with a 72-electrode machine deployed at ArcelorMittal Nippon Steel's plant and a 36-electrode version at Steel Dynamics Inc. These electrodes function collaboratively to prevent banding issues, offering a leap in accuracy and consistency for surface texturing. Its robust design allows it to adapt to the demanding environments of flagship steel and aluminum plants, allowing them to optimize production of surface-critical materials. The MSA's efficiency and performance deliver considerable long-term cost benefits while providing the flexibility for future capacity expansion.

The Rolltex Multi Servo Array is Sarclad’s state-of- the art, premier EDT offering. The MSA delivers unmatched roll texture control for surface critical strip applications such as automotive external panels

Two of the world’s leading steel suppliers have chosen Sarclad’s latest EDT roll texturing technology for their flagship plant expansions. ArcelorMittal Nippon Steel (AM/NS) has chosen the newly-launched Rolltex MSA 72 for their Cold Mill No.2 expansion in Hazira, India. Sarclad’s Rolltex MSA technology operates a Multi-Servo Array to deliver the highest levels of texturing performance. The 72-electrode MSA machine selected by AM/NS features two texture heads as shown below, each with 36 individually controlled electrodes. Steel Dynamics Inc. (SDI) has also selected Sarclad’s Rolltex MSA for their state-of-the-art mill investment in Sinton, Texas. The Rolltex MSA 36 features a single-sided texture head, which can be expanded to 72-electrode capacity by adding a second texture station in the future.

The ground-breaking texturing efficiency generated by MSA technology enables unrivalled accuracy, speed and consistency of surface texture on the roll and ultimately on the strip. Sarclad Rolltex MSA is the ideal choice for aluminium and steel flagship plants looking to increase volume and control of surface-critical strip into applications such as exposed automotive panels.
