MCTC manual
Recipe function
With the MCTC it is possible to store the current production settings into a recipe. All production settings of
all components will be stored within this recipe. An easy recall of the production settings is possible by
loading a previous stored recipe.
In case of a multi group configuration, one recipe includes all components and all groups.
The Recipe function has to be enabled in the System Configuration screen.
3.8.1
Material functions
The MCTC defines 4 different material types or component functions, each function represents another
behavior in how the material dosing quantity is calculated/dosed. Add is only available in combination with
Regrind.
V
Virgin
“Main material” or “Natural”
AddV
Additive Virgin Amount additive material related to the amount of Virgin material
R
Regrind
Grinded end product containing the right mix of Virgin and Additives
Add
Additive
Amount additive material related to the Shotweight, Batch or total EXT capacity
Regrind is defined as
“Grinded end product containing the right mix ratio of the required materials”
. Other
additives will be recalculated depending on the amount of Regrind added to the product mix. In the recipe
editor the entered percentage of Regrind is
not
part of the 100% product mix.
Required product mix
Mix
–
Regrind ratio
“Add” or Additive will be added to the product mix as specified in the recipe. The amount of material is
based on the full shotweight, extruder throughput or batch and will
not
be changed / reduced by the amount
of Regrind added.
3.8.2
Calculations
The amount of dosed material is calculated with the following formulas:
Virgin
𝑉 = 𝐵𝐴𝑇𝐶𝐻
− 𝑅𝑒𝑔𝑟𝑖𝑛𝑑
− 𝐴𝑑𝑑
− 𝐴𝑑𝑑𝑉
AddV
𝐴𝑑𝑑𝑉 = (𝐵𝐴𝑇𝐶𝐻
− 𝑅)
∗
𝐴𝑑𝑑𝑉%
Regrind
𝑅 = 𝐵𝐴𝑇𝐶𝐻
∗
𝑅%
Add
𝐴𝑑𝑑 = 𝐵𝐴𝑇𝐶𝐻
∗
𝐴𝑑𝑑%
BATCH
can also be read as shotweight or kg/h
