iFurn.pro does not auto-check "this tape won't fit this radius". If a part has a curved contour, the technologist picks a thinner tape themselves, so that it follows the radius without breaking. No indicators, no colour marks, no modal warnings "incompatible" — that's the technologist's decision.
What the system knows about a tape
A tape in the firm catalog has two numeric attributes relevant to curved banding:
- Width — which panel thickness the tape fits.
- Thickness — a thin tape (0.4 mm) bends more easily than a thick one (2 mm).
In the tape dropdown on a part's side both numbers are shown right inside the name, in [width/thickness] format. For example: [36/0.4] PVC white glossy means a tape 36 mm wide, 0.4 mm thick.
What the system does not do
When you pick a tape for a curved part:
- it doesn't validate the edge radius against the tape thickness;
- it doesn't highlight "incompatible" options in the list;
- it doesn't suggest alternatives;
- it doesn't block saving.
Formally you can pick a 2 mm tape on a 10 mm radius — the system will save, but in production the tape will lift off. Protection against this mistake is on the technologist and on the firm manager (via the "tape matched to panel" setting — only tapes the manager pre-matched to the panel appear in the list).
Industry guides (not enforced by iFurn.pro)
In furniture practice, for typical tapes, approximate minimum radii are:
- 0.4 mm — about 5 mm, fits most countertop corners.
- 0.8 mm — about 15 mm, standard for countertop roundings.
- 1.0 mm — about 25 mm, for large roundings.
- 2.0 mm — about 50 mm, for bar counters and wide arcs.
These are guidelines for the technologist, not datasheet values. The actual figure depends on the tape material, shop temperature, feed speed and equipment.
What to do if unsure
- Read the tape thickness right in the dropdown — it's written inside
[width/thickness]. - Compare with the part's radius (which comes from the part template).
- If the thickness is 1.5× or more larger than the expected minimum radius — pick a thinner one.
- If the firm catalog has no thin tape of the right colour — ask the manager to add one, or bring your own via "Customer's own materials".
Bottom line
iFurn.pro doesn't underwrite technological mistakes on curved banding. It's a tool that shows available tapes and saves the technologist's choice. Checking radius-to-thickness compatibility is the technologist's job, based on experience and the tape manufacturer's catalog.
