MAIN FRAME:

Deep Drawing Ring Frame Presses  with robust RING FRAME construction gives highest rigidity minimizing deflection of the frame to almost zero thereby giving incredible tools life & part quality. Oil dip gears provided to enhance press life & low sound level. No open parts for the highest safety of operator.

SLOW DRAW SPEED:

Three times slow drawing speed compared to ordinary mechanical draw press for highest drawn part quality with virtually no draw lines & still the same production.

AUTO GUAGE VARIATION CONTROL:

Auto gauge variation control system draws blank even with thickness variation minimizing rejections. Motorised blank holders reduce die setting time unbelievably just at the touch of a single button without any manual settings by operator.

QUICK AUTO EJECTION SYSTEM:

This system facilitates operator to remove drawn Components earlier for highest safety.

  • Improves metal flow times by keeping material in the work portion by nearly 300% longer period.
  • Slower velocity in the tool improves part finish.
  • Faster production speeds without increased forming speed thanks to faster slide return rate.
  • Lower impact, shock, noise and vibration improves die, press and other equipment life.
