ISBM Conditioning Temperature:
\nKorean Process Window Guide<\/h1>\n

Conditioning temperature is the single parameter that most Korean ISBM operators adjust most frequently and understand least precisely. It controls orientation quality, clarity, wall distribution, and cycle time simultaneously \u2014 and its process window is narrower than most Korean production teams assume. This guide maps the window for PET, PETG, and PP with the precision that EV servo machines make achievable.<\/p>\n

All temperatures are measured at preform surface in the conditioning station under steady-state production conditions (not during first 15 minutes of production). EV servo systems maintain \u00b10.3\u00b0C at setpoint; hydraulic systems typically show \u00b11.5\u20132.5\u00b0C variation. Window width values represent the range across which bottle quality passes standard commercial specification \u2014 not the range for premium applications.<\/p>\n<\/div>\n
