Semi-automatic vs fully automatic filling machines: when to automate and when not to

Full automation is not always the right answer. The decision depends on volume, SKU count, changeover frequency and budget — here is how to work through it.

Buying a filling machine is a long-term commitment. The decision should be based on total cost of ownership, not just purchase price.

What to consider

• Maintenance, spares and downtime costs often exceed the purchase price within five years.
• Test fills on your product prove performance claims.
• Supplier support — spares availability, remote diagnostics, service contracts — protects the investment.
• Automation level should match your volume, SKU count and changeover frequency.

Common pitfalls

• Choosing on purchase price alone.
• Not requesting a test fill before purchase.

Questions to ask your supplier

• What is the total cost of ownership over 10 years?
• What spares and service support is included?

The decision between semi-automatic and fully automatic filling depends on production volume, SKU count, budget and changeover frequency. A structured framework for making the right choice.
