Sintering in the heat DUO/Multimat2Sinter:
– Program #6: Speed program for bridges up to 6 units, T
– Program #7: Standard sintering for bridge frameworks up to 8 units, T
– Program #8: Sintering program for bridges of 9 units or more, T
Special sintering notes for large-span bridges (9 units or more)
Two wide-span bridges (9 or more units) can be sintered in the heat DUO or Multimat2Sinter at one time. Place
the objects on the special sintering bar for large-span bridges and keep in mind that the objects must not touch
the sintering block during the sintering.
Note the maximum dimensions for milling:
Height: 65 mm
Width: 90 mm
Placement of bridges with
sintering bar (9 or more units)
Sintering in third-party furnaces:
Sintering results may be adversely affected by e.g.:
• Incorrect sintering temperatures
• Insufficient heating power
• Incorrect temperature curves
• Incorrect object placement
• Insufficient heat-storing capacity of the furnace over the time of the sintering cycle
• Manufacturer-related or age-related variations in heating performance
• Object contamination by oxidation products emitted by non-enclosed heating elements
Any of these factors by itself or in combination may reduce the maximum strength of our above-mentioned
zirconium dioxide materials and compromise the life expectancy of the frameworks.
For these reasons, we cannot grant general approval for the use of third-party furnaces for sintering two-piece
abutments (mesostructures) and crown and bridge frameworks made of Cercon ht. We will, however, open
the system technically for the use of furnaces of third-party furnaces only on condition that the following
requirement are met:
