  1. “Under-aeration” Shell core making machine, CDRX

  2. 1. Specifications

  3. 2. Features • 1. Greatly reduced size of machine • Machine volume1/8 compared to conventional system • CDRX • Conventional Machine • Hopper • Valve unit • Head • Hopper • Valve unit • Core box • Core box • Over 3000mm • Unloader 1450mm • Head

  4. 2. Features • 2. Simplified structure

  5. 2. Features • 3. Better filled core by aeration sand filling • ■　By utilizing aeration sand filling technology, normally inferior sand filling from the bottom is improved or even better. • ■　Thanks to aeration, sand becomes easier to move by fluidization, improving filling to small area and density of sand. • Air tank • Core box • Aeration • Sand

  6. 2. Features • 4. Visualization of Quality • Compact Operation Panel • ■ Improved visibility and better operation • ■ Monitoring • Die temperature • Receiver tank pressure • Under-aeration head inner pressure (Optional) • Air flow volume (Optional) • Touch Panel • Graph display • Sensor value display

  7. 2. Features • 5. Effective capture of fume • ■Side suction without sacrificing workability and compact size • ■Can easily attached to deodorizer (Optional) • Deodorizer • Suction • Proposal example • Core box size 400~500 mm sq • Core weight 5kg • Air volume (assumption) 20m3/min • Deodorizer capacity varies depending on conditions and specifications

  8. 2. Features • 6. Utilization of existing die • ■　As long as the core box size fit within the specified size, existing die can be used without special modification. • 7. Easy accessibility to core • ■　Core(s) can be easily accessible and are taken out manually off of core box from the top of the machine.

  9. 2. Features • 8. Hollow core making • ■　By detaching the head before sand blow nozzle area is solidified, sand can be released, for possible making of hollow core • Hollow core • Die • Inside sand is dumped or released

  10. 3. Structure • Receiver Tank • Core box • Air supply valve • Storage chamber • Aeration chamber • Aeration inlets • Exhaust valve • Aeration inlets • Under-aeration head

  11. 4. Operation sequence • 2 Head Pressed to die • 3 Sand fill • 1 Start • Core box • Receiver tank • Head • 5 Head Separation • 4 Exhaust & Curing
