Iowa Precision Cornermatic Plus® Automated HVAC Ductwork Corner Inserter Machine
The Iowa Precision Cornermatic Plus Automated Corner Insertion Machine was specifically designed to reduce shop labor by addressing the difficulty with inserting corners into duct FITTINGS — from standard fittings to odd fittings like tight square throat elbows, flex connectors, offsets down to 2″ throats, and even the toughest inside or outside angle off-set transition fitting from 16-26 gauge. Sitting at an ergonomically comfortable table height, the Cornermatic Plus The Cornermatic Plus can handle any transverse duct connector (TDC) or transverse duct flange (TDF) fitting assembled on a bench and automatically and effortlessly completes eight (8) transverse duct connector (TDC) or transverse duct flange (TDF corner inserts — square and fully crimped — in approximately 20 seconds.
Features of the Iowa Precision Cornermatic Plus HVAC Ductwork Corner Insertion Machine:
- Specifically designed for the fabrication of duct fittings from 16-26 gauge — from standard fittings to odd fittings like tight square throat elbows, flex connectors, offsets down to 2″ throats, and even the toughest inside or outside angle off-set transition fitting
- Completes eight (8) corner inserts in seconds
- Operator friendly above ground, table height setting is ideal for fabricating small fittings — adjustable legs to match most bench heights
- Heavy gauge switch for 16-18 gauge performance and light gauge switch for 20-26 gauge performance enhances the crimping process — slows the Cornermatic down for heavy gauge and speeds it up for light gauge
- Fully automated — no switches or foot pedals — just push in and Cornermatic does the rest
- Corners are inserted square and fully crimped — no need to change the crimping adjustment when inserting corners in 16 to 26 gauge fittings
- Corners feed from below the work-surface allowing a clean, unobstructed work area
- Light bar indicates when the material has fully engaged on the right or left side of the infeed guide clamps — green light = Go, red light = No
- Light bar also indicates empty corner magazine
- Works with SMACNA-conforming, T-25a and T-25b flange and many other flanged duct systems without changing settings
- Each quick loading box holds eigthy (80) corners and loads in ten (10) seconds
