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 | 25 - 40 °C (77 - 104 °F) |
Predrying | Pre drying of the material is not necessary; if surface moisture forms as a result of changes in temperature, the material should be dried for 2 - 4 hours at 60 - 80 °C (140 - 175 °F). |
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. |
Cylinder Temperature | 160 - 180 - 200 °C, max. 250 °C (320 - 360 - 390 °F; max. 480 °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 3.5 : 1 |
Screens / Breaker Plate | A breaker plate and a screen pack are generally recommended in the extruder configuration in order to increase pressure. |
Die Land | <= 3 mm ( <= 0,12 in.) |
Extruder Head | Ca. 200 °C (390 °F) |
Die Temperature | Ca. 200 - 230 °C (390 - 450 °F) |
Predrying | Pre drying of the material is not necessary; if surface moisture forms as a result of changes in temperature, the material should be dried for 2 - 4 hours at 60 - 80 °C (140 - 175 °F). 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. |
