Thread: having a problem with my label casting help needed

Sounds like a reaction of the ink and something else

In will smudge etc if it gets wet try using Hair spray instead of the other goop Ian.

Heat transfer through the brass tube may have something to do with it heating the glue and resin/acrylic. This may also be causing many slit ends of wood and acrylic as the brass expands and shrinks.

Sounds like a heat issue to me Ian, are you turning between centres?

No Rumnut I am turning these on a mandrel but I am open to all answers and will tyry them all till it works.


Cheers Ian

Which is between centres.

little confused here I have always been under the impression that to turn between centres is done using a live and dead 60 degree centre at either end and and can be done with bushes or without bushes

seeing though in this case I did not do that I did it the standard way meaning a Morse #2 mandrel and bushes I though this would no be considered turning between centres ??


Can someone please enlighten me

Cheers Ian

Technically your right Ian although the headstock Mandrel is a dead centre and no matter what your using at the tail stock end either the 60deg or pin type to steady and centre the mandrel or even the hollow live centre. The fact is heat transfer still happens Brass is a Heat conductor and heats up quicker more so because of its thickness or lack of. It expands and contracts, which could be 1- effecting the glue on the back of the label 2 effecting the craft type sealer 3 effecting the resin and of course all of these in turn.

Use of the bushes gives you again between centres although they may not be pointed they are there to hold everything on centre (well hopefully).

Yes Ian, that is the accepted definition of TBC or turning between centres.

Using a mandrel with an MT chuck or with a collet chuck is not turning between centres.

Ian I'll send you a sample of the paper we use here at 043TURNING for all our lable casting.

GOOD thing about this paper is... You don't need to seal it
BAD thing is .....It's probably more expensive then what you currently using

Let me know how you get on

Mark

Do you sell the paper Mark or just use it for your own use?

Greg

Had never thought about selling it - we originally bought it for our HP2100 wide format printer to print up shop signs / advertising - we print up stuff on the adhesive paper and then attach it to Corr-flute (the white plastic stuff real estates agents use for signs ) occasionally we would get large sections of off-cuts, So one day I tried it on some custom labels firstly doing it as normal. but running out of time and having one mold cavity spare I thru in a tube without sealing it ....turns out is pretty darn good..

One word of warning.... don't over supply the MEKP (ratio under 2%) as the heat can and does cause the vinyl to shrink.


We are thinking about offering to print banners and signs so guys who attend markets and shows can exhibit their gear looking 100% and professional... but we need to work on some details

As to the stuff I sent Ian, its from our 30Ft x 610mm wide roll, so I haven't got a price per page, BUT If anyone would like to "road test" some, send me a PM and I'll flick you out a few "samples"

Mark

Sorry Dorno...

Didn't mean to hi-jack your thread -

IF the post above needs to be moved please feel free to "put it where the ....sun...>>>>>

I don't mind helping you out big fellait's all good

cheers Ian

It's about time looks like I may have solved the main problem I have been having so back to the job at hand as I have several orders to fill. It appears that the problem lied in the Sealing of the blank what I thought and read that should have been ideal in fact contaminated the blank and I believe it was heat that set it off

I hope these are a better effort than I had last week

The 1ST one is a American Vietnam Vets blank that is for an order
The 2ND is Australian Vietnam Vets
3rd is the Logo/Banner in which the International Security Assistance Force
(Nato Forces Afganistan

I am interested in you thought about the blanks as Usual

Cheers Ian

Looking good Ian with a kit will look much better.
