Alright........finally, here it is in ENGLISH (somewhat)! https://www.youtube.com/watch?v=Uq0Q84zp7LU
You have selected a really good sintering furnace. We have one at CAP and we are a reseller. mihm vogt has been manufacturing high end furnaces for decades. German built. If you are doing any quantity of work get the large one. In addition, you can't stand up full arches on a sintering block in the small one. For more info you can call Sam at 877-977-7889.
Which model of mihm-vogt Furnace is the best?
I need a reliable oven!!!
Going nuts trying to fix issues and worrying about our ovens on a nightly basis.....
Cost "approx" of the mihm-vogt?
Where to buy?
I am in Canada, whats available in North America in terms of distributors?
Thanks
Do these run off 110 volts ?(I don't want to have to put a third 220v in my lab) I'm really interested in the smaller one ,love the idea of completing a zirc unit from start to finish in one dayThe Dekema 664 and 674 both have speed cycles for both Dental Direkt and Amann Girrbach zirconia materials. The furnaces are identical with the exception of capacity. The 674 is larger fires
60 units in an 8 hour cycle 15 in 2:45. The 664 capacity is 40-12. The speed program is shorter,
Just 2:05.
220 only. Less expensive to operate and delivers the needed power.Do these run off 110 volts ?(I don't want to have to put a third 220v in my lab) I'm really interested in the smaller one ,love the idea of completing a zirc unit from start to finish in one day
Hi Kam,
You are pittin gone manufacturer against another, I can't speak directly for Shenpaz, The Mihm Vogt ovens have a great reputation and are 230Vac units. I like 230Vac because they tend to be more efficient and less harsh on power supply components. In regards to maintenance and cost of ownership, I would have to say the Mihm Vogt ovens have earned their good reputation legitimately. The need to change heating elements is not frequent, the heating elements can be changed individually and the overall reliability is great. The units utilize very high quality speed MoSi2 heating elements which have a long service life and do not contaminate easily. One thing to keep in mind isn't just the reputation, but the support and understanding of the oven market. I notice a lot of discussion relating to temperature and accuracy in regards to sintering ovens. The difference seen from oven manufacturer to oven manufacturer is caused by one simple issue with all sintering ovens:
There is no international standard for calibration above 1200C!
This means every oven manufacturer has a different calibration methodology and temperature curve. They also have different measurement methods and different allowable tolerances from the component level to the temperature measurement itself.
This is why if you buy an oven from one manufacturer, then one from another, your temperature settings can very greatly. The important part of the equation, would be build quality and a decision between capabilities & components.
Some ovens come with MoSi2 heating elements (in different grades) others come with SiC elements. The discussion relating to which one is better, depends on the application. The main differences between the two different materials is that MoSi2 elements can be affected by the out gassing of contaminates (typically from color liquids) into the chamber that ionize and can oxidize the surface of the heating elements. However, the high speed versions are very robust and do not typically suffer from this problem easily. The lower end versions (ovens with heat rates of 30C/Min or less) tend to have this issue to a much greater degree, which is why proponents of SiC elements typically pic on those lower end MoSi2 elements. All the same, the speed MoSi2 elements have heat rates in excess of 99C/Min and maximum surface temperature capabilities of up to 1850C! Although most of the ovens limit the programmable to 1650C, this gives you more room to play with your translucent zirc temps.
SiC elements have a couple of nice features, but some major drawbacks depending on your application. The nice thing about SiC elements is that they do not contaminate easily and can heat and cool quickly. They also tend to have a maximum surface temperature of 1600C, which leaves you with a programmable roof of usually around 1530C. However the main drawback that tends to bring people away from ovens with SiC elements is the need to replace elements quite often. Since their maximum surface temperature is 1600C and many of the newer translucent materials are firing near the maximum temperature of the oven, the life of the elements tends to be short. Furthermore, this leaves you little room to play with temperatures for translucency. Whats worse, is if one element goes out, you have to replace at least two at one time, because SiC elements have an electrical resistance that changes over time and are wired in parallel creating a problem where you would change the current going through one element if you put in a new element with a different electrical resistance.
If you have anymore questions, please let us know.
It would be the same cost for the same power draw... Watts = Volts x Amps220 only. Less expensive to operate and delivers the needed power.
