NOTE!
This section assumes that the reader has read and understands the name and data entry via
the touch screen as described in the
“Create a New Porcelain Program”
section. If not, please refer to
the previous chapter for detailed instructions on how to create a new program.
After selecting to create a pressing program, naming the pressing program follows the same steps as
naming a porcelain program. Please refer to
Creating a New Program
Porcelain Section, Display
Examples #20 - #23 for naming a pressing program. With the program name entered, the pressing
parameters screen should be up and ready to enter your program data. Refer to Display Example #31.
Display Example #31
Low Temp
– The entry temperature for the program. 700°C (1292°F) is typical Low Temp value.
Heat Rate
– The number of degrees per minute the temperature will increase
Start Vac
– This function has two modes of operation:
1.
Traditional Vacuum Mode – place any temperature equal to or greater than Low
Temp and less than or equal to High Temp. That is the temperature that the vacuum
pump will come on. Vacuum will be maintained for the remainder of the cycle
2.
Minimum Vacuum Mode – place a zero (0) or any value less than the Low Temp
value and vacuum will come on prior to the Press Hold Stage.
High Temp
– The maximum temperature that the program will run
Init. Soak
– The time in minutes and seconds that the ring will soak prior to pressing.
Press Hold
– The time in minutes and seconds that the pressing piston is engaged to the ring
2
nd
Hold Temp
– The temperature that the furnace will lower to after completion of the Press Hold
stage. This stage does not use pressing or vacuum.
NOTE!
The purpose of this stage is to provide controlled cooling to eliminate or
greatly minimize substrate stress. Place a zero (0) in this box to disable this feature.

H/R
–
The rate at which the temperature will drop from High Temp to the 2
nd
Hold Temp
2
nd
Hold
–
The time in minutes and seconds that the 2

Hold Temp will be held for
Cool Time
– The time in minutes and seconds that it takes for the door to come down
