Molding transparent PC part problem
I am facing a problem while molding a transparent PC part, it is like an open box, Transparency is an issue, when I increase the mold temp it sticks onto the core & ejection becomes difficult..any help?
What is your cycle time?
Check also the residence time in barrel/hot runner if any, don't exceed the recommended max time.
What flow index resin you have used? Is there any chance to use easy flow resin, remember that the mechanical strength is lowered if changing to easy flos resin. You could use then lower resin temp and risk to decompose will be lower.
Sticking issues with PC are normal and you need very well polished tool or big draft angles.
Some one mentioned mold release which is great to get your process going. Be prepared for scrap due to distortion from the spray.
You can also raise the nozzel temp,see the PC req...What is your wall thickness? 60 seconds is a long cycle time.
