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 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.
The product storage life is 12 months after delivery if storage instructions are followed. Store under dry conditions at room temperature (15–30 °C) away from heat sources and direct sunlight! Contact with nitrogen oxides must be avoided during storage!
