Weightpack designs and builds net-weight filling machinery in Italy for the world's most demanding liquid and powder applications. Unlike volumetric or level filling, every container sits on its own load cell — read up to 1,000 times per second — so the machine fills to actual weight, not estimated volume.
The payoff is precision: standard deviation under 1 gram with the mean held at setpoint ±0.5 g, maintained automatically through constant tare checks, self-learning, and scale re-zeroing every machine revolution. Weightpack handles nearly any viscosity — edible oil to peanut butter — in glass, cans, or plastic, and every machine is engineered around the customer's specific product and container.

| Feature | Advantage | Benefit to You |
|---|---|---|
| Load cell under every container, 1,000 reads/second | Fills to true net weight with live in-fill monitoring | Standard deviation <1 g means dramatically less overfill giveaway — the machine pays for itself in product savings |
| Self-learning with per-revolution scale reset | Continuously adapts to product temperature, density, and drift | Accuracy holds through the whole shift without operator tweaking |
| In-fill anomaly detection | Recognizes leaks or fallen containers instantly, closes the nozzle, rejects the package | No flooded machines, no half-filled product reaching customers |
| Station-exclusion fault tolerance | A problem station can be locked out while the machine keeps running | A single bad valve no longer stops the entire filling line |
| Built-to-application engineering | Each filler designed around your product and containers | No compromises adapting your product to a catalog machine |
Industries served: Edible oils, sauces & condiments, dairy, chemical, personal care, lubricants
Every gram of overfill is product you gave away. Drag the sliders to your line's numbers — this is what accurate weighing typically recovers.
