| Processing Guideline Injection Molding | |
|---|---|
| Cylinder Temperature | 180 - 200 - 220 °C, max. 250 °C (360 - 390 - 430 °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 | Residual moisture content might lead to processing problems and a reduction in the quality of the finished part. The use of a desiccant dehumidifying dryer is recommended. Drying conditions: 80 °C for 2-4 hrs; maximum dew point of the inlet air: -25 °C. The maximum residual moisture of the material should not exceed 0 ,02%. |
| 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. |
| Processing Guideline Extrusion | |
|---|---|
| Cylinder Temperature | 160 - 190 - 220 °C, max. 230 °C (320 - 370 - 425 °F, max. 450 °F) |
| Screw Geometry | Standard three-zone screw (e.g. polyolefin screw). The screw must be able to provide sufficient shearing. |
| L/D Ratio | At least 25 |
| Compression Ratio | At least 2,7 ... 3,5 : 1 |
| Screens / Breaker Plate | A breaker plate and a screen pack are recommended in the extruder configuration in order to increase pressure. In minimum two screen packs of 100 mesh are recommended. |
| Die Land | <= 3 mm ( <= 0,12 in.) |
| Extruder Head | Ca. 190 - 210 °C (374 - 410 °F) |
| Die Temperature | Ca. 180 - 190 °C (374 - 410 °F) |
| Predrying | Drying of the material for at least four hours at 80°C (175°F) is recommended. The moisture level of material has to be below 0.02 %. To avoid porosity in the profile a pre drying is recommended for wall thickness > 3mm. |
| Calibration | Generally not necessary; support elements may be required when extruding THERMOLAST® compounds with high hardness or when coextruding with standard thermoplastics. |
| Cleaning Recommendation | For cleaning and purging of the machine it is appropriate to use polypropylene or polyethylene. Machine must be PVC-free. |
