13.2 MaterialClass
Provides information about the material class, which can be used for the recipe calculation by the server or client. The TypeDefinition is 0:MultiStateValueDiscreteType, values are given in Table 35. Vendor specific classes can be used with EnumValue ≥ 100.
| EnumValue | ValueAsText | Description |
| 0 | MAIN | Main material |
| 1 | ADDITIVE | Additive e.g. coloring material |
| 2 | REGRIND_CLOSED_LOOP | Regrind with known composition, which is already considered in the internal dosing control and therefore excluded from the recipe calculation. |
| 3 | REGRIND_OPEN_LOOP | Regrind with unknown composition. Included in the recipe calculation. |
EXAMPLE:
With a recipe consisting of additive A = 9%, additive B = 10% and regrind ratio = 25%, the Percentage values calculate depending on the MaterialClass of the regrind material, shown in Table 36.
If the regrind composition is known (REGRIND_CLOSED_LOOP), e.g. sprue regrind in a stable process, where the regrind has the same composition as the recipe, only the main material share has to be mixed with the additives. The internal calculation percentage of Additive A calculates to 9 % × 75 % = 6,75 %, since 25 % of the additive (2,25 % in total) come from the regrind.
If the regrind composition is unknown (REGRIND_OPEN_LOOP), the regrind is treated as an additional component.
