Diagrams For better uniformity in molding especially when using regrind Max water content = 0.35%.35 Mpa/50 PSI) are favored. Using a low compression screw e.- general purpose 2:1 compression ratio) can result in unmelted Using a high back pressure to make Mold surface temperature: 5 mm (0.060 in.). May require mold temperature as high as Wall thickness greater than 3 mm (1/8 in.) may use a cooler (65 ) may use a cold mold surface down to 25 C (80 F). In general, mold It may be Other extrusionPREPROCESSING For better uniformity Desiccant hopper dryers are not required. Max. moisture 35% The screw should be a high compression ratio of at least The design should be approximately 35% each for the feed ), annealing is recommended to reduce M-Base Engineering + Software GmbH assumes no liability for the system to be free of errors.
