Why Small Parts Need a Better Box
Screws, fittings, and electronic components are easy to lose and quick to rust when stored in open cardboard. PP corrugated totes give small-part handlers a rigid, moisture-proof bin that stacks, labels, and returns. Rulowin makes them in depths from 60 mm to 300 mm so the box matches the part, not the other way round.
The fluted PP wall is light yet holds its shape under a stacked load.
Compartmentalising the Tote
Adjustable PP dividers turn one tote into a 12-cell kit for assorted fasteners. Dividers clip into moulded rails, so a line change takes seconds and no cutting. Clear lids let pickers see contents without opening, and a front label window holds a QR or kanban card. In a hardware DC, this cut mis-picks on small items from 1.4 percent to 0.3 percent.
Colour-coded bases separate metric from imperial stock at a glance.
Flow and Point-of-Use Storage
Shallow totes fit shelf rails, flow racks, and ASRS trays built to the 600 mm by 400 mm module. At point of use, stacked totes form a shadow-board bin that keeps hardware visible and counted. Because PP wipes clean, oily or greasy parts do not stain the bin for the next job, unlike cardboard which soaks through.
Empty totes nest to 20 percent height, saving return freight.
Lifecycle and Care
A corrugated PP tote survives 100-plus trips in a dry indoor loop. Periodic inspection checks divider clips and corner wear; damaged rails are swapped, not the whole bin. When finally retired, the mono-material board recycles in the PP stream. A tooling supplier running 20,000 Rulowin totes replaced cardboard bins entirely and removed 14 tonnes of fibre waste a year while improving pick accuracy.
Small parts deserve a container built for repetition.
Rulowin offers ESD-safe grades for electronic small parts so a single tote handles both storage and static protection without a separate pink bag. A connector maker using ESD totes cut static rejects on kitting lines from 1.1 percent to 0.1 percent in a quarter.
For hardware, fit a louvred panel version that hangs on the bench as a shadow board, so the right fastener is visible and counted at the point of use. Empty totes return nested to 20 percent height, and the dividers, being clip-in, move with the bin rather than getting lost in a drawer.
For audit trails, a scannable label window turns the tote into a counted asset rather than anonymous storage, so cycle counts stay honest without a separate bin-tracking system. Rulowin sees sites cut annual small-part losses by a fifth once the same tote is both the picker bin and the counted asset on the shelf.
