EMax pressing times...

[sidesh0wb0b]

I know it has been discussed before but i couldnt quickly find the thread sooooooooooooo

has anyone played with pressing times? and what have you found works best for 200g rings? heck even 100g rings? i can recall a guy i met once saying he adjusted pressing times to eliminate most of the reaction layer, or to help with full pressing on larger bridges (200g ring). what works for you for both 100g and 200g?

 

[sidesh0wb0b]

i guess i could add, i am pressing 100g rings at 3:30
200g rings at 4:30

i have not done many 200g rings recently (though one is burning out now),so i am curious to your pressing times

My ovens press until it cant press no more. Auto baby.

youve never adjusted pressing times to minimize reaction layer?

Reaction layer in an EP5000 is nearly nothing.

Nope. My oven presses until it senses resistance, and then stops pressing. Therefore I never needed to.

Not sure what oven you have but when I pressed in my old Optimal AutoPress I set it for 5min-100gm &
7:30-200gm.

Hey Gladiator,
What's the reaction layer like with that Dekema?

That seems too long.
My oven beeps and lights blue when the press begins. And finishes the press just a minute or two later..

Hey Gladiator,

I haven't pressed in it yet. I will eventually. But I still have the Programat 5K and I am thinking I would like to keep the Dekema as new as possible for as long as possible. And since we don't do PFM's here, not a drop of metal has been fired in it. Its still as clean as a virgins honey pot. -Morgan Freeman (Shawshank)

What are you waiting for? Is that thing some kind of trophy?

 

[Marcusthegladiator CDT]

I'm just waiting for a nice large case to press using the trix system that comes with the Dekema.

Chill. It may seem long but that's what worked. Had to press long enough to complete. No sensors. The rest of the numbers were as per EP500 on pg 60. It was very successful but every oven is different. And the reaction layer was not great. Nothing like this picture, the result trying a ProPress a couple years ago.

It depends on temperature and number of units for example pressing 1 unit, shouldnt take more than2 minutes . We pressed with the auto press having 3,4, unit in 100g super ring in 4 minutes.you could do 5 minutes if you are pressing 5 molars and premolars(100g super ring),veneers take less time beacuse of their flat surface and size.

i would love that, just dont have the option of it yet
the luxury of a startup LOL

thanks. at 3:30 for 100g i am planning to drop it to 3:15. i would like a little less reaction than i have....though its nearly nothing.
i spoke with my old long time rep for 15+ years at Ivoclar. to start for the 200g ring i will try 4:30 and see how it turns out. (pressing a pretty beefy 3unit bridge). will update the thread with any adjustments i make.
i am using an Image Press for anyone interested. thus far the oven has been an absolutely perfect oven!

I pressed a huge 3 unit a few days ago weight was 1.8 GMs. Press time was nearly 8 mins in EP5000.

thats not instilling confidence!!!

Sorry, but I thought itight be helpful. Doing a case again sucks.

I know lol just busting chops. I miss having an EP press. They are beautiful machines. However I went with some of the older press parameters to be sure I got the proper results. The new EP models press at 915C therefore increasing some of the press times. Especially on larger bridges. The older parameters include a high temp of 930C, which may end up making the glass molten enough to press faster. (Hey it sounds good in my head!)

Either way, we will know soon.....the ring is cooling now.
