The neck finish, however, is not stretched or blown \u2014 it is formed entirely by injection moulding in the injection station, before the conditioning and blowing phases. This means the neck finish dimensions are set entirely by the injection mould&#8217;s neck insert geometry and the injection process conditions, with no self-correcting blow pressure to compensate for injection variation.<\/p>\n<p style=\"font-size: 16px; margin-bottom: 0;\">The downstream consequence of neck finish variation is magnified by closure mechanics: a \u00b10.10mm neck OD variation on a PCO 1881 water bottle creates approximately \u00b18% variation in closure application torque \u2014 acceptable for Korean commodity water. A \u00b10.04mm variation on a Korean GPI 28\/410 cosmetic pump neck creates \u00b115% variation in pump head engagement force \u2014 producing audible play in the pump head and occasional pump head tilt on Korean K-Beauty toner bottles that fails Korean brand incoming inspection. A \u00b10.03mm variation on a Korean CRC neck creates \u00b122% variation in child-resistance ratchet engagement force \u2014 potentially causing CRC performance test failure (the 85% child resistance rate falling below the Korean KFDA requirement). Every Korean ISBM application tier has a distinct neck OD tolerance that reflects its closure&#8217;s sensitivity to dimensional variation, and every Korean ISBM neck insert must be designed, manufactured, and maintained to that tolerance.

The 3-start thread provides approximately 1\/3-turn engagement versus PCO 1881&#8217;s 1\/2-turn, enabling faster pump head application on Korean filling lines.<\/p>\n<p style=\"font-size: 16px; margin-bottom: 0;\">\u97d3\u56fdISBM GPI 28\/410\u30cd\u30c3\u30af\u516c\u5dee\u4ed5\u69d8\uff08\u7528\u9014\u5225\uff09\uff1a\u97d3\u56fd\u306e\u4e00\u822c\u6d88\u8cbb\u8005\u5411\u3051\u30d1\u30fc\u30bd\u30ca\u30eb\u30b1\u30a2\u88fd\u54c1\uff08\u30b7\u30e3\u30f3\u30d7\u30fc\u3001\u30b3\u30f3\u30c7\u30a3\u30b7\u30e7\u30ca\u30fc\u3001\u30ed\u30fc\u30b7\u30e7\u30f3 - \u30dd\u30f3\u30d7\u5916\u5f8424mm\uff09\uff1a\u00b10.05mm\u5916\u5f84 - \u6a19\u6e96GPI\u516c\u5dee\u3001\u6a19\u6e96\u30b9\u30d7\u30ea\u30f3\u30b0\u5b9a\u6570\u306e\u307b\u3068\u3093\u3069\u306e\u97d3\u56fd\u30d1\u30fc\u30bd\u30ca\u30eb\u30b1\u30a2\u30dd\u30f3\u30d7\u30c7\u30a3\u30b9\u30da\u30f3\u30b5\u30fc\u3067\u8a31\u5bb9\u53ef\u80fd\u3002\u97d3\u56fdK\u30d3\u30e5\u30fc\u30c6\u30a3\u30fcPETG\u30c8\u30ca\u30fc\u30dd\u30f3\u30d7\uff08\u30dd\u30f3\u30d7\u5916\u5f8424mm\u3001\u4f4e\u7c98\u5ea6\u30c8\u30ca\u30fc\uff09\uff1a\u00b10.04mm - \u30dd\u30f3\u30d7\u30d8\u30c3\u30c9\u306e\u50be\u304d\u3092\u9632\u3050\u305f\u3081\u3001\u4e00\u822c\u6d88\u8cbb\u8005\u5411\u3051\u88fd\u54c1\u3088\u308a\u3082\u53b3\u5bc6\u3002\u97d3\u56fd\u306e\u624b\u6307\u6d88\u6bd2\u5264\u30a8\u30bf\u30ce\u30fc\u30eb\u5bfe\u5fdc\u30dd\u30f3\u30d7\uff0824\/410\u3001\u30b7\u30ea\u30b3\u30f3\u30ac\u30b9\u30b1\u30c3\u30c8\uff09\uff1a\u30b7\u30ea\u30b3\u30f3\u30ac\u30b9\u30b1\u30c3\u30c8\u306e\u5727\u7e2e\u3092\u4e00\u5b9a\u306b\u4fdd\u3064\u305f\u3081\u3001\u00b10.04mm\u3002\u97d3\u56fd\u306e\u533b\u85ac\u54c1CRC\uff0828\/410 P&amp;T\u6a5f\u69cb\uff09\uff1a\u00b10.03mm - \u97d3\u56fdISBM\u30cd\u30c3\u30af\u5916\u5f84\u4ed5\u69d8\u306e\u4e2d\u3067\u6700\u3082\u53b3\u5bc6\u3002\u30cd\u30c3\u30af\u30be\u30fc\u30f3\u3067\u306e\u5c04\u51fa\u5145\u586b\u5747\u4e00\u6027\u3092\u6c7a\u5b9a\u3059\u308b\u30db\u30c3\u30c8\u30e9\u30f3\u30ca\u30fc\u8a2d\u8a08\uff08\u3059\u3079\u3066\u306e\u30ad\u30e3\u30d3\u30c6\u30a3\u3067\u00b10.04mm\u30cd\u30c3\u30af\u5916\u5f84\u3092\u9054\u6210\u3059\u308b\u305f\u3081\u306e\u524d\u63d0\u6761\u4ef6\uff09\u306f\u3001 <a style=\"color: #e11d48; font-weight: 600; text-decoration: none;\" href=\"https:\/\/isbm-blow-molding.com\/ja\/hot-runner-systems-in-isbm-moulds-engineering-principles-and-selection\/\">\u97d3\u56fdISBM\u30db\u30c3\u30c8\u30e9\u30f3\u30ca\u30fc\u30b7\u30b9\u30c6\u30e0\u30ac\u30a4\u30c9<\/a>.<\/p>\n<p><!-- S4 TAMPER EVIDENCE --><\/p>\n<h2 id=\"s4\" style=\"font-size: clamp(19px,2.8vw,25px); font-weight: 800; color: #881337; padding-bottom: 8px; border-bottom: 2px solid #e11d48; margin: 52px 0 18px;\">4. \u97d3\u56fdISBM\u30dc\u30c8\u30eb\u5411\u3051\u6539\u3056\u3093\u9632\u6b62\u30d0\u30f3\u30c9\u30c7\u30b6\u30a4\u30f3<\/h2>\n<p style=\"font-size: 16px; margin-bottom: 14px;\">Tamper evidence on Korean ISBM bottles is achieved through two mechanisms: the closure&#8217;s tamper-evident band (a ratcheted ring on the closure skirt that engages the bottle&#8217;s transfer bead or ratchet ring below the support ring), and the induction foil seal (a heat-bonded aluminium foil seal over the bottle neck seating surface that is destroyed upon first opening).

margin: 0; line-height: 1.65;\">P20 is the standard Korean ISBM neck insert steel for PCO 1881 and PCO 1810 beverage applications. At \u00b10.10mm PCO OD tolerance, P20&#8217;s hardness provides adequate dimensional stability for typical Korean beverage production volumes (8\u201315M shots\/year per cavity). P20 does not provide sufficient corrosion resistance for Korean PETG processing \u2014 PETG&#8217;s slightly acidic melt (pH equivalent from glycol modifier hydrolysis) causes P20 to develop surface oxidation at the thread profile crests after 3\u20134M shots, increasing thread surface roughness and beginning to affect neck OD dimensional consistency. Acceptable for PET beverage; replace with 2316 for PETG cosmetic applications.<\/p>\n<\/div>\n<div style=\"background: #fff1f2; border-radius: 6px; padding: 12px 16px; border-left: 3px solid #e11d48;\">\n<p style=\"font-size: 14px;

margin-bottom: 0;\">Korean ISBM neck finish measurement protocol is structured at three levels of frequency and precision. Production shift check (5 bottles per cavity per shift, digital calliper): neck OD at 2 quadrants (0\u00b0 and 90\u00b0), ovality calculation, go\/no-go gauge pass; results logged in production quality record. Weekly dimensional audit (10 bottles per cavity, CMM or air gauge): neck OD at 4 quadrants, thread height T-dimension, L-dimension, support ring OD, seating surface flatness; results compared to the Korean brand&#8217;s dimensional specification (PCO 1881 ISBT drawing, GPI 28\/410 closure supplier print, or brand proprietary drawing). Quarterly neck insert dimensional inspection (coordinate measurement on the neck insert itself, not the bottle): measure insert bore at 4 quadrants, thread profile geometry (depth, pitch, angle), split-line gap, and seating face perpendicularity; compare to original as-manufactured insert dimensions to confirm wear is within the re-serviceable range.

The neck insert assembly \u2014 steel neck inserts mounted in the injection station cavity \u2014 heats progressively from 20\u00b0C at Korean morning startup to 65\u201380\u00b0C at steady-state production temperature (the thermal contribution from the PET melt at 280\u00b0C conducted into the neck zone). The thermal expansion of the P20 or 2316 stainless steel neck insert over this 45\u201360\u00b0C temperature rise is approximately 0.008\u20130.012mm OD increase per degree Celsius \u2014 at 50\u00b0C rise, the insert bore expands by 0.4\u20130.6mm. This bore expansion translates directly to a 0.4\u20130.6mm increase in neck OD from Korean morning startup to steady-state production temperature. Korean ISBM producers who perform their shift OD measurement at morning startup and use this measurement for the full production lot may be validating bottles against a cold-insert baseline that does not represent the warm steady-state production. Korean neck finish QC best practice: measure neck OD at 30 minutes after production start (when the neck insert has reached approximately 70% of its steady-state temperature), at 2 hours (near steady-state), and again at 6 hours \u2014 the progressive OD increase from these three measurements confirms the thermal expansion behaviour and the steady-state OD that the Korean brand&#8217;s closure supplier has calibrated their closure dimensions against.<\/p>\n<\/div>\n<div style=\"padding: 18px 22px; border-bottom: 1px solid #fecdd3; background: #fff1f2;\">\n<p style=\"font-size: 15px; font-weight: bold; color: #881337; margin: 0 0 8px;\">Q2 \u2014 \u30d7\u30ed\u30bb\u30b9\u8a2d\u5b9a\u304c\u540c\u3058\u3067\u3042\u308b\u306b\u3082\u304b\u304b\u308f\u3089\u305a\u3001\u97d3\u56fd\u88fdISBM\u30ad\u30e3\u30d3\u30c6\u30a3\u306e\u30cd\u30c3\u30af\u5916\u5f84\u5024\u304c\u7570\u306a\u308b\u306e\u306f\u306a\u305c\u3067\u3059\u304b\uff1f<\/p>\n<p style=\"font-size: 15px; color: #374151; margin: 0; line-height: 1.7;\">Cavity-to-cavity neck OD variation in Korean ISBM multi-cavity production has three primary causes. First \u2014 neck insert dimensional variation from manufacture: even when neck inserts are ordered from the same Korean mould maker for a 4-cavity or 6-cavity tool, individual inserts may have bore dimensions that vary by \u00b10.03\u20130.06mm from the nominal dimension due to machining tolerance stack-up in the insert manufacturing process. Korean ISBM producers should measure all neck inserts with an air gauge before mould assembly to confirm all inserts are within \u00b10.02mm of each other \u2014 inserts outside this batch consistency target should be reworked before assembly. Second \u2014 differential thermal expansion from uneven cooling circuit flow: cavities with higher cooling water flow (lower coolant temperature, shorter circuit path) run cooler, and their neck inserts maintain slightly smaller OD than cavities with restricted flow (higher coolant temperature). A cooling circuit flow balance check (measuring coolant temperature at inlet and outlet of each cavity&#8217;s cooling circuit) often reveals \u0394T variations of 5\u201312\u00b0C between cavities in Korean multi-cavity production \u2014 requiring flow rate balancing with adjustable flow restrictors to equalise cavity temperatures. Third \u2014 differential injection fill rate: in multi-cavity hot runner systems, cavities at different distances from the manifold central feed can fill at slightly different rates, creating different packing pressures and different final neck OD dimensions. Korean ISBM hot runner balancing \u2014 either geometric (equal runner length) or thermal (independent heated zone per cavity) \u2014 is required to achieve consistent cavity-to-cavity neck OD for Korean K-Beauty and pharmaceutical applications.<\/p>\n<\/div>\n<div style=\"padding: 18px 22px; border-bottom: 1px solid #fecdd3;\">\n<p style=\"font-size: 15px; font-weight: bold; color: #881337; margin: 0 0 8px;\">Q3 \u2014 \u97d3\u56fd\u306eISBM\u88fd\u9020\u696d\u8005\u306f\u3001\u97d3\u56fd\u30d6\u30e9\u30f3\u30c9\u306e\u8cc7\u683c\u304c\u518d\u53d6\u5f97\u3055\u308c\u308b\u3053\u3068\u306a\u304f\u3001\u30cd\u30c3\u30af\u30a4\u30f3\u30b5\u30fc\u30c8\u306e\u4ea4\u63db\u3092\u3069\u306e\u3088\u3046\u306b\u7ba1\u7406\u3059\u3079\u304d\u3067\u3057\u3087\u3046\u304b\uff1f<\/p>\n<p style=\"font-size: 15px; color: #374151; margin: 0; line-height: 1.7;\">Korean ISBM neck insert replacement \u2014 necessary when insert dimensional drift exceeds the application tolerance from production wear \u2014 must be managed without triggering a full Korean brand re-qualification event (which typically requires 4\u20138 weeks and 30\u201350 first-article samples). Korean ISBM producers can minimise re-qualification scope by demonstrating that the replacement insert produces neck OD within the original first-article specification range. Protocol: (1) Before replacing, measure the worn insert bore at 8 positions (4 quadrants \u00d7 2 heights) and document the wear map \u2014 this establishes the dimensional baseline for the wear life record; (2) After inserting the new insert, run 10 qualification shots and measure neck OD at 4 quadrants on each of 5 consecutive bottles per cavity; (3) Confirm the new insert OD is within \u00b10.01mm of the original first-article mean OD; (4) Submit the dimensional comparison data to the Korean brand quality team as a &#8220;component change notification&#8221; (\ubd80\ud488 \ubcc0\uacbd \ud1b5\ubcf4) rather than a full first-article resubmission \u2014 Korean brands who have accepted a pre-agreed component change protocol from their ISBM suppliers allow insert replacement without full re-qualification if dimensional data confirms equivalence.

color: #374151; margin: 0; line-height: 1.7;\">Korean brand incoming neck finish inspection uses three methods depending on the application tier. Method 1 \u2014 Attribute gauge (go\/no-go ring gauge): the most common Korean beverage brand incoming inspection method. A calibrated go ring gauge at nominal OD + tolerance (e.g., PCO 1881 + 0.10mm go) and no-go ring gauge at nominal OD \u2212 tolerance (PCO 1881 \u2212 0.10mm no-go) are applied to each sampled bottle \u2014 pass if the go gauge slides over the neck threads smoothly, fail if the no-go gauge engages. This method is fast (5 seconds per bottle) and requires no measurement skills, making it practical for Korean filling line incoming inspection at 100 units per delivery lot sample. Method 2 \u2014 Variable measurement with digital calliper or air gauge: used by Korean K-Beauty, pharmaceutical, and premium beverage brand quality departments for supplier qualification audits and periodic incoming verification. Records actual OD values at 4 quadrants; enables statistical process capability calculation (Cpk) for supplier assessment. Method 3 \u2014 Functional closure engagement test: 20 consecutive bottles are fitted with the production closure and torqued to the Korean brand&#8217;s specified application torque (typically 15\u201320 N\u00b7cm for 28mm closures) \u2014 all 20 closures must achieve full thread engagement without cross-threading, and all 20 must unseal at a torque within the brand&#8217;s specified removal torque range. This functional test is the most commercial test method \u2014 it directly validates that the neck finish performs correctly in the Korean brand&#8217;s filling and consumer use context, regardless of whether the actual OD measurement is at the tolerance limit or the nominal centre.<\/p>\n<\/div>\n<div style=\"padding: 18px 22px; background: #fff1f2;\">\n<p style=\"font-size: 15px; font-weight: bold; color: #881337; margin: 0 0 8px;\">Q6 \u2014 \u97d3\u56fd\u306e\u70ad\u9178\u98f2\u6599\u88fd\u9020\u306b\u304a\u3044\u3066\u3001\u97d3\u56fd\u306ePCO 1881\u3068\u97d3\u56fd\u306eMCA 29\/25\u30cd\u30c3\u30af\u306e\u9055\u3044\u306f\u4f55\u3067\u3059\u304b\uff1f<\/p>\n<p style=\"font-size: 15px; color: #374151; margin: 0; line-height: 1.7;\">MCA 29\/25 is an alternative Korean CSD neck finish introduced by some Korean beverage equipment manufacturers as a higher-flow alternative to PCO 1881 for Korean 1.5\u20132.0L CSD bottle formats. PCO 1881 at 27.43mm OD is the dominant Korean CSD neck standard for 250ml\u20131L formats; MCA 29\/25 at 29mm OD with a 25mm inner bore provides approximately 35% larger flow area for faster filling at Korean high-speed CSD filling lines operating above 40,000 bottles per hour. The engineering differences relevant to Korean ISBM neck design: MCA 29\/25 has a larger OD (29.0mm versus PCO 1881&#8217;s 27.43mm) \u2014 requiring a correspondingly larger neck insert bore and a slightly heavier neck weight (+0.4\u20130.6g per bottle); the MCA 29\/25 thread pitch is the same as PCO 1881 (2-start), but the thread depth is slightly greater to accommodate the larger diameter engagement. Korean ISBM producers who supply Korean CSD bottlers who have upgraded their filling lines to MCA 29\/25 closures for their 1.5L Korean cola line may receive Korean brand requests to transition their ISBM bottle from PCO 1881 to MCA 29\/25 \u2014 a neck insert change (not a full mould body change) that requires new inserts and a neck OD re-qualification against the Korean brand&#8217;s MCA 29\/25 closure supplier&#8217;s dimensional specification.<\/p>\n<\/div>\n<\/div>\n<div style=\"background: linear-gradient(135deg,#0c0204 0%,#e11d48 100%);
