Processing Guideline Injection Molding | |
---|---|
Cylinder Temperature | 170 - 190 - 210 °C, max. 220 °C (340 - 370 - 410 °F, max. 430 °F) |
Hotrunner | Hot runner temperatures: 180 - 220 °C (356 - 428 °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 | 25 - 40 °C (77 - 104 °F) |
Predrying | The material is hygroscopic, residual moisture content might lead to processing problems and a reduction in the quality of the finished part. Drying conditions: 80 °C for 4-6 hrs. The maximum residual moisture of the material should not exceed 0,05%. |
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. |
