✔ Cosmetics – Lotions, creams, shampoos
| Model | Throughput | Accuracy | Capacity | Dosing Type |
|---|---|---|---|---|
| LB-10M | 15 BPM | ±0.5ml | 50ml–5L | Gross/net weigh |
| LB-100D | 30 BPM | ±0.2ml | 100ml–20L | Multi-head net |
| LB-100F | 60 BPM | ±0.1ml | 1ml–50L | Hybrid volumetric/gravimetric |
Special Features:
Anti-vibration load cells for noisy environments
Overfill recovery system (saves 3–5% product)
Material Options: 316L SS, PTFE-coated, or full plastic (PP/PVDF)
✅ Self-Calibrating – Automatic zero-point adjustment
✅ Recipe Memory – 100+ formulas with touchscreen HMI
✅ No Flow Dependence – Unaffected by viscosity changes (1–200,000 cP)
Comparison vs. Volumetric Fillers:
| Metric | Weigh Filler | Piston Filler |
|---|---|---|
| Viscosity Impact | None | ±5% variance |
| Foam Handling | Excellent | Poor |
| Changeover Time | <2 mins | 5–10 mins |
Infeed – Bottle unscrambler or bag placer
Filling – 1–16 heads with auto-tare
Checkweighing – Reject ±1% out-of-spec containers
Capping – Servo-driven torque control
Optional:
Nitrogen flushing for oxygen-sensitive products
Robotic case packing
✔ High-Speed Phase – 80% of dose at maximum flow rate
✔ Precision Phase – Final 20% at reduced speed (±0.1% accuracy)
✔ Drip-Free Cutoff – Anti-drip valves eliminate product waste
Auto-Tare – Remembers container weight for repeat cycles
Pre-Cutoff – Stops filling 2-5mL before target to compensate for flow lag
Recipe Memory – Stores 100+ formulas (HMI touchscreen)
| Model Type | Nozzles | Speed | Capacity | Accuracy |
