Shung Dar - NC Servo Feeder, Straightener & Uncoiler (3in1) SNR1
Shung Dar - NC Servo Feeder, Straightener & Uncoiler (3in1) SNR1

Shungdar - 3 in 1 uncoiler & NC straightener feeder SNR1 series which the coil thickness from 0.3 ~ 3.2mm and the range of width is 200 ~ 600 mm and coil weight is for 1tons. Application finished products including computer casing, small hardware parts and light and thin stamping products of various cabinets ...etc.

3 in 1 model is made by uncoiler, straightener and feeder; the overall structure is compact, shortening the factory of the area. All feeding parameter setting and control are concentrated in one operation screen and manual box, stable performance, accurate feeding, and high leveling, saving manpower space, high-automatic feeding equipment around the press machine.

The mandrel expansion of SNR1 series is operate by manually, when the coil weight up to 3 tons the hydraulic expansion is an option. Coil O.D up to 1200mm, air operated hold down arm cutting the coil or compacting coil during production. Uncoiler of SNR1 is driven by motor with reducer, uncoiler feeding with driver become a loop area and into straightener, loop control by photo sensor.

The straightener motor is operating by AC motor and the inverter for speed adjustment and straightener roll can adjust the roller gap through the manual worm, feeding roll stabilizes the material into the stamping process.
