pressing the e.max in anything other than the Ivoclar press takes a little bit of trial and error. most all other pressing ovens out there and friends that I know that use them, all say increasing the pressing high temp is the place to start. try a base temp of 700C, heat rate of 60C, high temp of 940C, pressing time of 8 minutes, pulling vacuum the entire time.
I think you bought the wrong oven. Now Jensen is distributing Dekama and not Zubler anymore. But not because the Zubler pressing furnaces are not good - no, because Zubler terminated the contract.
I cannot help you with your Dekema furnace but you should now the latest news.
By coincident I'm Mr. Zubler and I confirm that the Zubler Variopress 300e can press the new e.max multi ingot perfect. We are even pressing e.max ingots twice as fast as Ivoclar and the results are outstanding.
In Germany Ivoclar takes meanwhile care that the sales people say yes you can perfect press e.max ingots in a Zubler VP300.
The problem you have is, that the lab people get told that the multi ingot is coming and only EP3000 or EP 5000 can press it correct -
-But the Multi Ingots are not coming - Ask Ivoclar why?
What a marketing - telling the lab people you need a EP 5000 or an EP 3000to press the new Multi Ingots and when you ask they are not available and they are not coming - Only Ivoclar can play such games with the customers.
Zubler has a Patent for Pressing Lithium Dislicate faster ( total time for a 200gr. Ring pressed in our VP300e from putting the ring on the pressing tray until the oven opens and you can take the ring is 16-17 min. - total time - on a EP5000 it's 32 min.
Now you can see why Zubler's VP300e has no reaction layer and the best possible results in pressing e.max ingots on the press oven market.
Now compare those results from the new VP300e with a Dekema Furnace -
Total Pressing time is like Ivoclar - The reaction layer - you should compare it with a Zubler VP300e - what a difference.
Zubler did more then 1000 R&D pressings to establish a virtuell software sensor in the ring. This is how we work - German ingeneering -
I can give you lab's they have the new e.system and ask them what happens with there EP 5000. They are using our oven to press e.max not Ivoclar or others.
Dr. Ed Mc Laren at UCL also have expierience with the VP300e - new version.
Everybody who reads this and has already an VP300 send an email to
[email protected] and we can upgrade your oven, even the
oven was bought in 2006.
You can get the Advanced Press Technolgie and you get outstanding results.
Plus we have the Zubler 144 investment (
e in Germany) for pressing too.
This is how we support our customers, even your 6 year old oven is
upgratable, because we develope and produce everything in our family owned
