ZP3-Y Side-Port Mini Vacuum Cups, UMS/UMN, 4-16 mm, B5/B5

Quick Selection Guide for ZP3-Y (UMS / UMN, B5/B5)

Goal: help you pick the right cup size quickly by surface, required load, and working mode.

Step 1 — Surface and environment check (mandatory before choosing size)

Surface allow list

• Recommended: glass, polished aluminum, polished steel, smooth painted rigid metals
• Typical: hard ABS/PC/PMMA, PVC/PP/PE with stable flat contact
• Use only after trial if slightly textured: rigid engineering plastics with good finish

Do not select until corrected:

• Porous / woven / rough / open-cell surfaces
• Wet, oily, dusty, dusty-porous, or condensation-prone surfaces
• Cracked, chipped, soft foam, warped or concave surfaces at contact points

Step 2 — Load mode

• Static mode: no acceleration at the gripped object, low-frequency motion
• Dynamic mode: robot or linear acceleration, frequent start/stop, short transport distance
• Vibration mode: shaker, high-frequency equipment vibration, uneven stop-start impact

Step 3 — Choose diameter / number of cups

Estimation method (engineering only, not a certified lifting value)

• Formula: suction force F = P × A
• 10 kPa and 13 kPa are used for comparison only
• Recommended safe load = 50% F for static, 25% F for dynamic/vibration
• Total recommended payload = Σ(single-cup safe load) × system margin (0.9 static, 0.8 dynamic)

Estimated vs tested value policy

All numbers above are engineering estimates from geometry + vacuum level. For production use, always add a customer test:

• Use your real object, real mounting bracket, and real vacuum line
• Record suction/vent time and holding drift
• If any test result is below the estimated static value, scale model or reduce cycle speed and re-test

Minimum validation parameters before bulk use

• Single piece mass
• Number and distribution of contact points on the part
• Vacuum pressure setting and valve response time
• Static vs dynamic ratio of movement, and vibration level
• Surface cleanliness class (dry / dry+dusted / oily+wet)

3-step acceptance SOP (recommended)

1. Cycle 1: 3 repeated pick attempts, observe attach stability and whether first vacuum holds.
2. Cycle 2: Hold for 10 s at max target load and check for leak-down or drift.
3. Cycle 3: 10-cycle repeat test with full sequence timing; target: no earlier-than-expected release and no cup slip.

Boundary and derating

Operating boundary (practical)

• Humidity: keep environment below condensation risk; avoid direct moisture films on contact face
• Temperature: follow your system-specific cup-material limit; keep near catalog limits and test at the lowest temperature point
• Chemical media: avoid strong solvents, fuel/oil mist, strong acid/alkali, oxidizers and corrosive rinse fluids near seal area

Safety use: not for direct human-safety lifting certification. If surface, speed, or environment is uncertain, request a pre-production test plan before mass order.
