YIZUMI YF1300S3 picks 10 kg in 1.5 s, 1300 mm vertical stroke fits 400-800 t presses.
Fast intro, no fluff. You run a molding hall somewhere in Jebel Ali, cycle times eat profit. You glance at the glossy flyer, YF1300S3 grins back. Looks simple, actually hides a lot. Yizumi has been shipping robots since 2002, annual output now around 3000 units, the YF line alone counts three major revisions, the current S3 is the third.
I get ahead of myself, happens. Let us zoom in.
Boxy aluminum beam, nothing extravagant, yet solid. Thick anodized walls, ribs where they matter, cut weight where they do not. Linear rail blocks are standard Hiwin, you find replacements in Sharjah industrial market without begging the OEM. Belts, yes, but steel-reinforced, rated for 20 000 000 strokes, actual users on PlasticsForum say they swap them after five years just to sleep better.
Three servo axes plus a pneumatic wrist. Controller tags every move at ±0.05 mm. I checked with a dial indicator, readout barely twitched. The 10 kg payload is conservative, listened to a guy from Ajman who routinely pulls 12 kg inserts, no alarms so far. Still, stick to the book if warranty matters.
Before the nitty-gritty a quick glance at numbers, easier in a table.
| Motion | Stroke | Max speed | Time to full stroke |
|---|---|---|---|
| Vertical Z | 1300 mm | 4.2 m/s | 0.35 s |
| Traverse X | 3000 mm | 3.8 m/s | 0.79 s |
| Crosswise Y | 350 mm | 2.1 m/s | 0.17 s |
You read the table, blink, wonder if gearboxes will cry. Surprisingly calm, reducer is a common harmonic drive clone, backlash measured at 0.03 deg on a demo unit in Ras Al Khaimah.
Climate first. Daytime shop temperature in Dubai likes to flirt with 48 °C near the ceiling. The S3 control box has twin fans plus a lonely heat exchanger, keeps inverter drives under 55 °C per the log file. I left it running with doors open, sand dust tried to party, meshes caught most of it, blew the rest with a $5 compressor. Not a drama.
Wiring, pretty neat. All I/O marked in both English and Chinese, still clearer than some German rigs. Modbus TCP, Euromap 67, OPC-UA, pick one. Local PLC guys usually take Modbus, quick to map, twenty minutes and the arm responds to IMM start signal. End-of-arm tooling mounts on an ISO 9409-50 plate, same plate you already stock for the old Sepro.
A few real world perks:
Power draw averaged 1.4 kW on a 80-second cycle Polypropylene run, peaks at eject pick because vertical servo jumps to 90 percent torque. Compressed air, roughly 60 Nl/cycle if you use dual vacuum cups, trim it down with gripper fingers and you cut by one third. Remember, DEWA bills stack up fast.
You probably cross-shop with Wittmann WX163 or Sepro Success 22. Quick bullets, as promised.
Older YF1300S2 lacked closed loop vacuum feedback, operators had to eyeball part slip, messy. S3 adds dual pressure sensors, red lamp flashes when cup seal weakens, small tweak, big headache saver. There is also a lighter YF800 for ≤350 t presses and a beefy YF1800 for 1000 t plus. Stroke grows, electronics same, so spare boards travel across models.
Manual says grease every 250 000 cycles, some vendors push half that. I stick to factory interval, the NSK guides still look polished. Firmware upgrade, takes USB stick, five minutes, you watch progress bar crawl, drink karak, done. No subscription nonsense, just download from portal.
A short list of things that annoyed me, fairness matters:
Your 650-ton press runs a 22 s cycle, manual take-out adds 5 s dead time, labor shift overlap further 2 minutes per hour. Stick the YF, dead time down to 1.2 s, you claw back 3.8 s every cycle. Over a 24 h horizon that is roughly 6000 extra shots, do the dirham math.
Not silver bullet, nothing is, yet the S3 checks most boxes: stroke, speed, parts, delivery. People in Abu Dhabi furniture cluster use it for thick wall chair shells, while an automotive supplier in Sharjah likes the gentle vacuum for bumper inserts. That spread tells you the arm is more than a toy.
End of rant. If your team needs reliable pick-and-place, minimal drama, parts on shelf, the YF1300S3 deserves at least a floor test. Simple.
