ISBM Neck Finish Engineering:
\nKorean Bottle Guide<\/h1>\n

The neck finish is the only zone of the ISBM bottle that never gets stretched \u2014 it is injected at final dimensions and must perform precisely at closure engagement, tamper evidence, and dispensing sealing. Every 0.05mm neck OD deviation is amplified at the closure: a closure torque failure, a seal leak, a consumer complaint. Korean ISBM neck finish engineering defines the tolerances, materials, and inspection protocols that make the unstretched neck the most dimensionally precise zone of a Korean ISBM production run.<\/p>\n
