3. | Press Input | to display #2, “Shot size of current mold”. Using arrow keys, |
| set the total shot size (parts and runners) of the current mold capacity in grams. | |
4. | Press | Input to display #3, “Screw recovery time”. Using arrow keys, set |
| the screw recovery time (in seconds). For Extrusion Constant operation, skip this step! | |
5.Press Input to display #4, “Calibration weight for additive”. Enter ’0’ and proceed to calibration mode below for calibration of additive material.
Recipe Setup For Extrusion:
1. | Turn power switch to ON position. | ||
2. | Press | Input | to display #1, “Additive %”. Using arrow keys, set additive |
| ratio. |
|
|
3. | Press | Input | to display #2, “Throughput of extruder”. Using arrow keys, |
| set the total extruder throughput in g/min or lb/min. | ||
4. | Press | Input | to display #3, “Extruder screw speed”. Using arrow keys, |
| set the extruder screw speed RPM expected during production. | ||
NOTE: for Extrusion Constant operation, this step will be skipped.
5.Press Input to display #4, “Calibration weight for additive”. Enter ’0’ and proceed to calibration mode below for calibration of additive material.
Calibration:
1. Press “Calibration” | button to start this procedure. Display will show - - |
- - |
|
2.Place the plastic calibration cup on the scale and tare so that the weight of the cup (approx. 24gr.) is not calculated in the calibration procedure.
3.Remove cover of the calibration box, secured by two 5mm Allen screws, under the
| dosing disc assembly and insert plastic cup provided in top of dosing hopper. | ||
4. | Press | “Run” and the dosing disc turns 1/4 turn. This fills all pockets of | |
| dosing disc. Dump the dosed material back into the dosing hopper without weighing | ||
| and replace plastic cup in calibration box. |
| |
5. | Press | “Run” and the dosing disc turns 1 complete revolution. Remove | |
| the calibration cup with the material and place on the gram scale. Enter the weight on | ||
| the scale into the controller | using the arrow keys. Empty and replace | |
| calibration cup. |
