Appendix A Basic Parameter Settings

A-2 Recipe Formulas

The following formulas can be used to determine if a recipe is appropriate or possible.

Injection Molding

For injection molding applications, compute the dosing disc speed and total number of disc revolutions using the following formulas. Recipe limitations are listed in the table following the equations.

Recipe Limitations for Injection Molding

Motor Speed (rpm)		Maximum
	Max Speed (rpm)		Min Speed (rpm)
3	3		0.15
8.4	8.4		0.4
11.5	11.5		0.6
38	38		1.9

Extrusion - Simple

For extrusion applications, compute the dosing disc speed using the following formula. Recipe limitations are listed in the table following the recipe.

Disc RPM = ( Additive - %) x (Total Extruder Throughput - lb / hr) 13.22 x (Disc Calibration Weight - g)
