SCSExtrude

The Next Generation Control System

First introduced in 1986, the Granco Clark Supervisory Computer System (SCS) was developed to provide extruders with a completely integrated control system for automated extrusion lines. In 1994, when development began on the next generation of SCS, we commissioned an independent market research firm to gather customer’s opinions on performance, preferences and recommendations for improvement.

We Listened to You

We wanted to make improvements to the SCS based on your perspective, not ours. The consensus: you asked for a more flexible, user-friendly system. The result: SCS Extrude, the next generation nerve center for automated extrusion lines.

Interfacing with Ease

The SCS has always enhanced efficiency by developing production schedules, loading equipment parameters, tracking faults, and logging production and downtime data. Now it does all this and more in the user-friendly environment of Windows NT®, the platform replacing the previous VAX-based system.

Windows NT is a high-performance, widely used operating system that can be easily integrated with standard information management systems. In addition to the new platform, SCS Extrude is now developed in MS Visual Basic, using a relational database. With standard Windows point-and-click screens, the graphical interface is easy to use.

The Control Station, outfitted with a powerful industrial computer, drives the application software that communicates between the SCS Extrude and floor-level PLCs. This system allows the extrusion manager or press crew to easily prioritize the job list, assess line performance, monitor faults and alter parameters.

Smart Troubleshooting

SCS Extrude now incorporates a second-generation fault diagnostic system, providing even faster troubleshooting for more extrusion line uptime. The fault system provides four levels of information. First, a list of faults is displayed on the SCS computer screen. After selecting a fault from the list, the operator can choose from three different displays: a system diagram of the fault location, a visual image of the device that detected the fault, and a description of the appropriate troubleshooting steps to be taken.

Don’t Take Our Word for It

UMEX, a new extrusion facility, in Downey, California, recently purchased a complete Granco Clark system for its 3600-ton press line. UMEX produces high-volume, large-shape extrusions, up to 51 feet in length, for a wide range of applications, including the construction of truck trailers, air cargo containers and communication racking systems.

UMEX chose a Granco Clark system with SCS Extrude because, "Granco Clark was willing to work closely with us to customize a system that would meet our specific needs. They offered more flexibility with the development of our system and outstanding support and instruction for a smooth start-up," explained General Manager Jack Courduff.

"The SCS Extrude saves equipment parameters. Setup is exactly the same every time, allowing us to consistently produce a higher quality product. The data logging and event tracking give us instant access to production data. We have been impressed with the performance of the SCS, the extrusion equipment and the level of service provided by Granco Clark," noted Karl Requejo, Plant Engineer.
