Crating services: the equipment behind the operation

Also known as

What crating services actually sell

A crating service sells three things: the box, the labour to fit the goods inside it, and the paperwork that lets the shipment move. Of those, the labour is local and hard to scale, the paperwork is administrative, and the box is the only part that is a manufacturing process. That is why the equipment decision sits inside a service business.

It also explains why crating services get expensive at the margin. A service that buys boxes in is paying for someone else's production and someone else's freight, and every unusual box size becomes a special order with a lead time. A service that makes its own boxes turns an unusual size into a drawing change.

The constraint moves rather than disappears. Once a crating operation makes its own boxes, its capacity is set by the slowest stage in its own line, and its quality is set by whether the drawing is reproduced rather than remembered.

The three stages a crating operation needs

The standardized production system runs three stages in sequence. Buckle fastening locks the panel joints with steel buckles rather than nails. Steel-edge forming cold-rolls galvanised strip into the edge profile, with an encoder cutting to length. Hydraulic pressing sets that formed edge flat against the panel.

The published figures that size such an operation are: 5–12 mm plywood and up to 9,000 mm of assembly length on the DA-8000, at 30–60 fastenings per minute; 6 kW on the forming machine; and a press quoted at 30 t nominal force on the 2.5 m build, with the series built from 40 to 100 t and platen sizes to 1,300 × 8,500 mm.

Recommended floor space is 3 × 3 m for the buckle machine, 5 × 2 m for the forming machine and 3 × 3 m for the 2.5 m press — 21 m² in total, before working aisles and panel turning areas. A crating service that already has a hall usually finds the aisles, not the machines, are what the layout has to be designed around.

In-house crating versus buying the service

Bringing crating in-house makes sense when the boxes repeat, when the sizes are unusual, or when the lead time of a bought-in box is the thing that loses orders. It makes less sense when volumes are low and irregular, because a line has a floor space and a power connection that have to be paid for whether it runs or not.

The honest test is the box drawing. If the operation can describe the boxes it ships as a small number of repeatable drawings, a line fits the business. If every shipment is a one-off, a crating service is doing the right thing by buying boxes in.

Where the answer is in between, the three stages can be bought separately. Each machine is quoted with its own specification sheet, so an operation that already forms edges can add the fastening stage alone, and one that only needs to close joints never buys the press.
