ISBM Blow Station Engineering:
\nKorean Bottle Guide<\/h1>\n

The blow station is where the thermally conditioned preform becomes a bottle in 0.8\u20132.5 seconds. Blow pressure profile, valve timing, nozzle geometry, blow dwell, and exhaust sequence each control a different aspect of bottle quality \u2014 and each parameter that is wrong produces a different, diagnosable defect signature. Korean ISBM engineers who understand these mechanics adjust one lever at a time.<\/p>\n

Pre-Blow: 4\u20138 bar<\/span>
\nHigh-Blow: 28\u201342 bar<\/span>
\nDwell: 1.2\u20133.0 s<\/span><\/div>\n
