When clients visit our workshop for the first time, most of them walk straight to the CNC machine. The question is usually the same: what difference does it make to my stand? The short answer is that it affects two things directly, how clean the finish is and how predictable the schedule is. Here is the longer answer, including what CNC does not fix.
What CNC actually does on a stand
A CNC router is a computer-controlled cutting machine. The designer’s drawing becomes a cutting file, and the machine follows it on the sheet. On stands we mostly cut MDF, plywood, acrylic, PVC foam board and aluminium composite panel.
In practice that means wall carcasses and counters, curves and rounded forms, raised logo letters, shelves with cut-outs sized to the product, and joints that lock pieces together without a lot of screws. Some of this can be done by hand with saws and jigs, though not to the same accuracy and not at the same speed.
The difference in finish
You see it first on the edges. Hand cutting on a curve or on small letters always leaves a slight wave, which then needs filler and sanding. A precise cut means less filler and a smoother final coat. On high-gloss or lacquered stands this shows far more than on a matt one.
The second difference is how the parts meet. A stand is built in the workshop and assembled in the hall. If two panels are a few millimetres apart in size, you get gaps on site and the crew ends up cutting and patching in the aisle. When every panel comes from the same cutting file, the work in the hall is assembly rather than construction.
The third is repeatability. Order three identical counters or display modules and you get three identical pieces. That matters for companies doing several shows in a row or planning to reuse part of the stand.
The difference in timing
Many stand builders send cutting out to other workshops. That is fine in quiet months. In the busy autumn and winter season, when the big Tehran shows come one after another, those outside queues get long, and a one-day delay at someone else’s shop lands straight on your build schedule.
We do the cutting in our own workshop. Once a design is approved, we decide when cutting starts, and if a piece is wrong at the trial assembly it is recut the same day.
To be fair about it, CNC speeds up the cutting, and cutting is only part of the job. Paint still needs to dry, print still needs producing, and wiring and lighting take their own time. CNC takes days off a schedule, not weeks.
What CNC won’t fix
The machine cuts exactly what is in the drawing. A mistake in the drawing becomes a precisely cut mistake. That is why we check dimensions against the hall plan and the client’s product sizes before a file goes to the machine.
Late design changes don’t get cheaper either. Once a sheet is cut, a change means new material and a new cut. We like the design fixed about four weeks before opening. Changes after that are possible, but each one costs time and money.
And a bad layout stays a bad layout, however accurately it is cut.
What we need from you
- Exact dimensions of the products going on the stand, or better still a sample, if shelves or holders are to be cut to fit them.
- A clean vector file of your logo for raised letters. A photo or a low-resolution file has to be redrawn first.
- The hall plan and your stand position, because permitted height and column positions affect panel sizes.
- A decision on reuse. If you want to take the stand, or part of it, to the next show, tell us at the start so joints and part numbering are designed for repeated assembly.
CNC makes the biggest difference on custom stands: shaped counters, curved walls, raised logos, product display shelving and anything meant to be used more than once. You can see some of this work in our projects. If you are planning a show in Tehran from abroad, our trade fair services in Tehran page explains how we handle the local side. Pick your date from the fair calendar, send us the hall plan, and we will go through which parts of your stand are worth cutting on the machine and which are not.
