Direct answer
Filling machine cost is driven by what must be measured, how the product behaves and how the container is presented. A simple semi-automatic filler for one stable liquid is a different project from an automatic multi-head system handling foamy, viscous, abrasive, hazardous or particulate products across several pack sizes.
Key takeaways
- Define product behaviour and the commercial fill requirement.
- Compare the dosing system and container handling separately.
- Request a repeatability trial using actual product and packs.
- Do not buy from dose range and headline speed alone.
Define the requirement before comparing price
The correct dosing principle depends on viscosity, density, temperature, foam, particles, aeration, corrosiveness and whether the declared quantity is mass or volume. Product-contact materials and cleaning also affect the price.
- Record minimum and maximum dose
- State fill tolerance and test method
- Provide viscosity, density and temperature range
- Identify particles, dust, foam, strings or hazardous properties
Compare the complete installed solution
A lower-cost filler may still need manual container loading and removal. Automatic systems require indexing, no-container/no-fill control, nozzle movement, drip control, guarding and integration with upstream and downstream equipment.
- Compare number of filling heads and effective cycle time
- Check product supply, hopper, pump or pressure requirements
- Include nozzles, change parts and anti-drip features
- Compare cleaning access and product recovery
Remove hidden cost and performance risk
A machine can technically cover the volume but fail on product replenishment, settling, foam, particles, container neck size or clean shut-off. The smallest and largest doses should be tested with representative product.
- Check accuracy across the full hopper or supply condition
- Include product temperature at filling
- Allow for container variation and unstable bases
- Measure giveaway as well as underfill risk
Ask for evidence before committing
Record individual fill results, average, range, speed, drips, foam and interventions over a representative run. Acceptance should identify the measurement equipment and whether results are corrected for tare or density.
- Raw fill-weight or volume data
- Production-speed and intervention record
- Cleaning and changeover demonstration
- Approved wetted-parts and seal specification
