White area at gate and hazy throughout bottle, Injection Molding (Machine)

Kenplas Forum ==> Injection Molding (Machine) ==> White area at gate and hazy throughout bottle

Well the gate C.T ( Crystallization) is unavoidable due to hot/cold front.
The body C.T can be reduced by reducing mould temperature (6-8°C is recommended), increase chilled water pressure(6-8 bar) in mould.

I am molding a large preform. This mold does not have a heated gate area. I am having a white ring around the sprue area and the bottle is hazzy when fully packed out. If underpacked bottle looks clear, However it is still white at gate area. Any suggestions?
