The advantages customers experience with RSDC’s blanking lines include:

  • Automated processes to provide consistent and efficient production
  • Feed forward capabilities to enable auto rejection of material pieces based on defect data communicated by the steel mills
  • Dual inspection capabilities to ensure 100% top and bottom inspection
  • Elevated inspection stations to provide better viewing and optimized inspection processes
  • Automatic “one button” rejection to dispose of non-conforming pieces during inspection
  • Rockwell software automates part recipe set up and part processing history to continually ensure best manufacturing practices
  • Dual stacking system with four pilers to provide continual stacking without halting production
  • Online packaging capabilities to ensure material is ready to ship off the line

RSDC’s blanking lines include three 800-ton exposed capable lines and one 600-ton unexposed press. The 800-ton press lines feature in-line leveling, high pressure hot water wash, top and bottom electrostatic oiling, and 100% top and bottom inspection. The 600-ton line features in-line leveling and hand-stacking of parts. Together, these four lines offer a combination of capabilities that are rare industry-wide, including:

  • Crane loading with a capacity of up to 90,000 lbs. on all four lines
  • Automated top and bottom coil loading on all four lines
  • Press beds of 102 x 204 inches and 102 x 144 inches
  • Up to 84-inch blanking
  • 6 high leveler with 9 over 10 rolls and full-width intermediate rolls
  • Sheet height of up to 53 inches with a 31-inch adjustable pass line
  • Elevated inspections stations for better viewing and optimized inspection processes
  • Piler unloading via crane or hi-lo
