As any factory-floor engineer can tell you, finding solid solutions to the simplest manufacturing problems often can yield the greatest benefits.
This was the case at Silver City Aluminum (www.scaluminum.com), Taunton, Mass., a manufacturer of custom aluminum extrusions and finished parts.
The extrusion process is pretty straightforward. Large rolls of aluminum-called billets-are fed into the extrusion machine, pressed into a die using hydraulic power, and heated. It emerges as a slat, blind, or other shaped-aluminum product.
"Occasionally, after a billet has been cut, the excess fails to fall off," say Silver City's maintenance manager, Larry Johnson. "When this hanging piece hits the die, it can destroy it-to the tune of about $10,000 in replacement costs-or cause the machine to shut down, leading to expensive production losses." The challenge for Silver City was to find an inspection solution that could fit into a space-constrained area, be able to inspect a large area, and perform reliably in harsh environmental conditions while not breaking the bank.
