NPC, a commercial print, mail, and digital communications leader, faced growing challenges with its aging scrap collection system. Initially installed in the late 1990s and modified multiple times, the system’s outdated controls had become unreliable, making Lockout/Tagout procedures difficult and risking production downtime.
NPC sought a streamlined, centralized control system that could be installed with minimal production interruptions to ensure long-term operational reliability, improved safety, and future scalability.
The Challenges
NPC’s legacy scrap collection system relied on multiple independent control panels with minimal interlocking and no documented schematics. Over time, various modifications led to a piecemeal setup consisting of four PLC relay stations and numerous standalone control stations.
The system had deteriorated to a point where:
System shutdowns were risky
Operators were hesitant to shut down the system for fear it would not restart.
Lockout/Tagout procedures were not reliable
Safety compliance was compromised.
Control inefficiencies led to operational headaches
Operators had limited control over performance and troubleshooting.
Scalability was a concern
NPC required a system capable of supporting up to three additional scrap lines in the future.
NPC required a new control panel with modern automation, a single operator interface, and built-in expansion capacity to resolve these challenges. The installation also needed to be executed within a strict seven-day shutdown window to avoid significant production delays.
AES Solutions
To meet NPC’s needs, AES engineered and delivered a state-of-the-art control panel solution with the following key features:
Centralized Control System
A single, dedicated PLC-driven panel replaced the multiple outdated control stations.
User-Friendly Operator Interface
A touchscreen control panel streamlined operations, improving accessibility and ease of use.
Enhanced Safety and Compliance
The new system fully supports Lockout/Tagout procedures, ensuring maintenance teams can safely service components.
Scalability for Future Growth
The new panel was designed with excess capacity, allowing for the seamless addition of three more scrap lines.
Minimized Downtime During Installation
AES worked closely with NPC’s engineering and maintenance teams to coordinate the electrical contractor, ensuring a smooth installation process.
The project was executed in carefully planned phases to minimize downtime. Before the shutdown, the new panel was set, and the wiring was roughed in. Over five days, outdated wiring was removed, new wiring was installed to code, and the system was brought online. Finally, the panel was commissioned, and hands-on operator training was provided to ensure a smooth transition.
Results
With AES’s solutions, NPC now operates a modern, reliable scrap collection system that enhances safety and efficiency. The new control panel helps ensure consistent uptime, supports proper Lockout/Tagout compliance, and provides built-in capacity for future expansion. Brought online in just five days, this project was completed with minimal downtime and provides long-term operational reliability for the scrap collection system.
Scope of Work
- High-Powered Shredding System:
A 150HP dual-shaft shredder enables continuous, high-capacity scrap processing, reducing the need for manual intervention and supporting Arconic’s goal of minimizing downtime. - Efficient Material Handling:
The system includes a semiautomatic rack tipper with a chain feed slat table and a 48-inch-wide feed and discharge conveyor, ensuring smooth and consistent material flow throughout the process. - Turnkey Installation and Training:
AES provided a comprehensive, end-to-end service package covering minstallation, commissioning, and on-site training, equipping Arconic’s personnel with the skills needed to operate the system confidently.
