| Processing Guideline Injection Molding | |
|---|---|
| Cylinder Temperature | 180 - 210 - 240 °C, max. 250 °C (360 - 410 - 460 °F, max. 480 °F) |
| Hotrunner | Hot runner temperatures: 200 -250 °C (390 - 480 °F). The runner should be empty after a maximum of 2 - 3 shots. |
| Injection Pressure | 200 - 1000 bar (2900 - 14504 psi) (depending on the size and weight of the part). |
| Injection Rate | In general, the fill time should not be more than 1–2 seconds. |
| Hold Pressure | We recommend to derive the optimum hold pressure from determining the solidification point, starting with 40 % - 60 % of the required injection pressure. |
| Back Pressure | 20 - 100 bar; if color batches are used, higher back pressure is necessary. |
| Screw Retraction | If an open nozzle is used processing with screw retraction is advisable. |
| Mold Temperature | The mold temperature depends on the hard component. A temperature exceeding 80 °C (175 °F) should be avoided. The common temperature is 40 - 60 °C (105 - 140° F). |
| Predrying | To achieve optimum mechanical values, drying the material for 2 - 4 hours at 60 - 80 °C (140 - 175 °F) is recommended. |
| Needle Valve | With materials < 50 Shore A the use of a needle valve is advisable. |
| Screw Geometry | Standard 3-zone polyolefine screw. |
| Residence Time | The residence time is to be set as short as possible with a maximum of 10 minutes. |
| Cleaning Recommendation | For cleaning and purging of the machine it is appropriate to use polypropylene or polyethylene. Machine must be PVC-free. |
