If you run a small warehouse, fulfilment operation, or trade counter, you will know the scenario: an operator picks up a flat-packed corrugated blank, folds it square by hand, presses down the base flaps, and tapes the bottom — before they've packed a single item. Then they do it again. And again. For every order, every shift.
This is case erection, and for many UK businesses, it is entirely manual. It is also one of the biggest hidden time drains on a packing line. Independent studies in warehouse operations consistently show that manually forming and taping a case bottom takes between 15 and 30 seconds per box. On a modest line processing 200 orders a day, that's over an hour of productive time spent purely on forming boxes — time that could be used picking, packing, or dispatching.
The Problem Goes Beyond Speed
Speed is only part of it. Manual box forming also introduces quality problems that most operations don't track carefully enough. When a person forms a box under time pressure, the base flaps are often not fully squared before taping. The result is a box with a slightly misaligned base — which causes it to rock on the conveyor, jam in the case sealer, and occasionally fail entirely when loaded with product weight.
For anyone using a case sealer downstream, a poorly formed box is a real operational headache. The sealer assumes a square, correctly dimensioned box. Feed it a mis formed one and you risk misaligned tape, machine jams, and damaged product.
The SIAT F105: Semi-Automatic Case Erection for Growing Operations
The SIAT F105 Case Erector (£3,895 excl. VAT) is designed precisely for operations at this stage of growth: busy enough to feel the pain of manual erection, but not yet at the volume that justifies a fully automatic line.
The F105 is a semi-automatic machine. The operator places a flat case blank into the machine; the F105 then automatically folds and forms all four bottom flaps, holds the box square, and — paired with a case sealer — seals the base with tape. What previously took 15–30 seconds of manual effort per box takes a fraction of that. SIAT's published figure is a 50% time saving on the case forming stage.
Critically, every box the F105 produces is formed to the same geometry. The base flaps are folded to the correct angle every time, so the box sits square and feeds cleanly into a sealer. The inconsistency that causes jams and mis formed seals downstream is removed entirely.
What This Means in Practice
For an operation running 200 boxes per day, a 50% reduction in forming time can save 30 to 45 minutes of labour per shift. Over a working week that's 2.5 to 3.5 hours — time that can be redirected to picking accuracy, dispatch quality checks, or simply handling higher order volumes without adding headcount.
For operations already using a SIAT case sealer, the F105 integrates directly via a pneumatic pusher, presenting each formed box to the sealer automatically. This creates a continuous, consistent flow from flat blank to sealed case — without a person manually handling the transition.
Is the F105 Right for Your Operation?
The F105 suits operations handling a consistent box format at low to mid volume. If your range runs to multiple box sizes that change frequently throughout the day, a different solution may be more appropriate. But if you run one or two standard formats and want to remove the time and quality problems of manual forming, the F105 is a straightforward, well-proven step forward.
