How do the manufacturers cut the fin slots into cardboard tubes?

Rex R · Jan 23, 2014

at a guess, something like a plunge router.

Why aren't there burn marks?

Sometimes there are. It all depends on the power of the laser and how much time is spent in contact with the material.

They cut the burned parts off with an Xacto knife. :flyingpig:

My guess is they are combination Punched (all 3 or 4 slots at the same time) with tooling punches designed and made for a slotting machine with insert backing mandrel that speeds production far beyond what laser cutting could do. Could be pneumatic or hydraulic either would be fairly easy to set up and maintain speed and accuracy leaving no visible mark on the tubes as to how the material was removed.
Slot punches similar to gasket or leather punches are used all the time for such elongated hole removal.

I like this explanation. Sounds more logical than using the Electricity a Laser requires, not to mention the Speed.
Good Call Micromeister.

I do believe that all the methods mentioned here are used though many of the smaller new companies do have their tubes laser cut to save tooling costs and the hassle of using routers.
