ISBM Mould Cooling Channel
\nEngineering: Korean Guide<\/h1>\n

Cooling time accounts for 35\u201355% of every Korean ISBM cycle. The difference between a well-engineered cooling channel layout and a generic one is 1.5\u20133.5 seconds per cycle \u2014 which at 8-cavity, 16-hour shifts translates to KRW 40\u201395M additional annual revenue on the same machine and mould. This guide gives Korean producers the engineering basis to capture that difference.<\/p>\n
