Conturo 0.5mm edgebanding buckling

[stvrowe]

I have just started using 0.5mm edgebanding with the Conturo and am experiencing less than an ideal edge with it even after trimming.  I do not experience this with 1, 2, or 3mm edgebanding.  The materials used are Rehau PVC edgebanding with white glue pucks and temperature set at the recommended 200C.  What appears to be happening is the glue seems to be thermally buckling the edgebanding at both the beginning and end of the application.  I have reduced the amount of glue deposited and this does help but does not eliminate the buckling.  I have not reduced the temperature from that recommended. 

Pictures are attached and any suggestions would be appreciated.  Even after trimming, there is a very slight deformation right at the trimmed edge.

I don't have a Conturo Steve but .5 is awfully thin. I would say that the temp is too high for that thin. It might also be that the particle board is to porous with that thin of plastic and 200deg glue. Try going over it with a plain iron and see if you get the same results.

Good luck. Bryan.

Hi
Reduce the heat and this should solve the problem

I use 1mm or thicker not used 0.5

To me it seems like you have the heat set to high so I would try and reduce the heat

Thanks guys, the heat setting was my next step.  It would be nice to know what the best range of temperatures is for the various adhesives.

Steve,

What setting do you use with .5mm? I have the same issue at 180 degrees.

With 1mm I have no problems.

I don't have a Conturo but do use a stationary edgebander.
200°c seems high,  on average our machine is at 185, in the winter I set at 190.  Now of course there is a fundamental difference in that the Conturo melts it's glue "as needed",  my machine melts all the glue in the pot prior to start.

Never used the 0.5 mm abs/pvc edge band, I think it would work on a stationary machine, but can see why the Conturo has problems with this.

On a stationary machine the glue is heated in the pot and is then pushed against the workpiece using rollers. There is some distance between heating and the edgeband.  With the Conturo the heating happens very close to the band, so it also gets heated and deforms.

If you want thin edge banding you can always use laminate, with the added benefit that it will not turn yellow over time. I like it much more then the abs/pvc band. Only downside is the dark line you get.
I usually can convince the customer to go for laminate after I show them a 5 year old abs edge that has gone from white to yellow.  If the edge isn't subjected to sunlight much it 's of course less of an issue.

Phil,
I got the same problem, tried to lower temp down to 335 F still dose not help. it seem dose not like .5mm PVC tape. Any suggest would be appreciated.

350°- 355° is a good temp for .5mm banding.

We also recommend running the Conturo in speed setting #2. This will keep the banding moving faster past the hot glue nozzles, in turn, not exposing in to the hot glue as long.

Lastly, make sure that you're fully engaging the feed roller on the material that the banding is being applied to. This could bunch up the edge banding and expose it to heat longer.

Speed 2..... I think speed to can be a bit fast to enter and exist a work piece.

I normal enter at speed 1 then kick up to speed 2.
