500ml to 1000ml 注塑吹塑成型指南
Injection blow molding at 500ml to 1000ml requires larger machine platforms — ZQ80, ZQ110 and ZQ135 — with higher injection weight capacity, larger platen dimensions and longer core rods than the ZQ40 and ZQ60 used for standard 10-300ml IBM. This guide covers machine selection, process parameters, material options, cavity count economics and quality outcomes for large-format IBM containers in pharmaceutical, food, household chemical and personal care applications.

ZQ80 handles 500ml PP IBM at 4-6 cavities (total shot ~200-300g) and 500ml HDPE IBM at 4 cavities (total shot ~220-260g). Primary machine for 500ml daily chemical, personal care and food IBM
ZQ110 (500-750ml)
540g max shot
ZQ110 covers 500ml at 6-8 cavities and 750ml PP IBM at 4-6 cavities. Larger 1100×460mm platen for multi-cavity large format. Primary machine for 500ml pharmaceutical and 750ml household IBM
ZQ135 (750ml-1L)
650g max shot
ZQ135 handles 1L PP IBM at 4-6 cavities (total shot ~300-400g) and is the primary Korea Ever-Power machine for 1L wide-mouth pharmaceutical and household IBM. Maximum IBM format in the ZQ range
Key process difference
Longer cycle
500ml-1L IBM cycle time 6-10s versus 3.5-5s for 50-200ml IBM, due to taller preform cooling time. Output per machine per hour is lower than small format but preform wall mass requires complete cooling before stripping

Large Format IBM vs EBM: Process Economics at 500ml–1L
At 500ml-1L container formats, the IBM versus EBM process economics shift compared to smaller formats. At 50-200ml, IBM’s quality and zero-flash advantages are compelling and IBM is clearly superior on most criteria. At 500ml-1L, IBM remains the process of choice for pharmaceutical and precision personal care applications, but EBM becomes more competitive for commodity household and food containers due to lower tooling cost and larger format EBM machine capacity. Korea Ever-Power’s ZQ80, ZQ110 and ZQ135 IBM machines serve the 500ml-1L IBM segments where IBM’s quality, zero-flash and neck precision advantages remain commercially valued by brand owners — pharmaceutical companies requiring GOST, BP or USP-compliant PP containers, personal care brands specifying neck OD tolerance for pump fitment at 500ml+, and food companies requiring zero regrind virgin PP or HDPE for food contact large-format containers.
| 格式 | IBM ADVANTAGE | EBM ADVANTAGE | MARKET DECISION |
|---|---|---|---|
| 500ml Pharma | Neck precision, zero regrind, GOST/BP compliance | Lower tooling cost | IBM strongly preferred — pharma specs drive IBM selection regardless of format |
| 500ml Personal care | Pump neck OD ±0.05mm, zero flash base, surface finish | Higher output per cavity, oval shapes | IBM preferred for pump-closure brands; EBM for oval-body or commodity formats |
| 750ml Household | ESCR base, wall uniformity, zero flash | Lower tooling, coextrusion EVOH option, oval | IBM for premium brand ESCR and base integrity; EBM for commodity budget household |
| 1L Food/supplement | Zero regrind virgin material, wall uniformity, neck precision | EVOH barrier coextrusion, lower tooling | IBM for clear-neck supplement and food; EBM for EVOH barrier or very large volume commodity |

Large Format IBM Process: Cycle Time and Cooling
LARGE FORMAT IBM CYCLE TIME AND OUTPUT — ZQ110 REFERENCE DATA (PP)
500ml PP / 6 cav
Cycle: 6.5s → 3,323/hr
500ml PP IBM at ZQ110 6 cavities, 6.5s cycle (vs 4.0s for 150ml PP). Lower output per hour but IBM quality advantages (zero flash, neck precision) retained at 500ml format
750ml PP / 6 cav
Cycle: 8.0s → 2,700/hr
750ml PP IBM at ZQ110 6 cavities, 8.0s cycle. Longer cooling time for taller 750ml preform wall. Annual output at 2-shift: ~13M bottles/year per ZQ110
1L PP / 6 cav
Cycle: 9.5s → 2,274/hr
1L PP IBM at ZQ110 6 cavities, 9.5s cycle. ZQ135 at 8 cavities 9.0s achieves 3,200/hr for 1L — higher cavity count more efficient than faster cycle for 1L IBM economics
Cooling dominates
65–70% of cycle
At 500ml-1L IBM, preform cooling time accounts for 65-70% of total cycle (versus 55% at 100-200ml). Mould cooling water temperature (10-15°C) and channel design dominate large format IBM productivity optimisation
Core Rod Length for Large Format
500ml-1L IBM preforms are taller than standard small-format IBM preforms — a 1L IBM bottle at 220-240mm height requires a core rod exposed length of approximately 250mm from platen face to rod tip. At 250mm core rod length, straightness tolerance of ±0.01mm over the full rod length is critical: a 0.05mm straightness error at the rod tip produces a 0.05mm eccentricity in the 1L preform wall, translating to a ±15% wall thickness variation in the 1L bottle at 1.2-1.4mm target wall. Korea Ever-Power manufactures large-format core rods in H13 tool steel, precision-ground to ±0.01mm over full rod length and inspected on V-block before mould delivery. Annual core rod straightness re-inspection is recommended for 1L IBM programmes at >10M cycles/year.
Cooling Channel Design for Large Format
Large-format IBM injection cavity cooling must efficiently extract heat from a taller, heavier PP or HDPE preform mass within the ZQ cycle time allocated to cooling. Korea Ever-Power’s large-format mould cooling channel design for ZQ110 and ZQ135 programmes uses helical cooling channels around the injection cavity diameter (versus straight-bore channels in smaller moulds) to maximise cooling water contact surface per unit cavity height — reducing large-format IBM cycle time by 10-15% compared to straight-bore cooling designs at equivalent preform wall thickness. Blow mould cooling for 500ml-1L IBM also uses enlarged channel diameter (10-12mm versus 8mm standard) to reduce cooling water pressure drop across the taller blow mould cavity height, maintaining consistent 10-15°C cooling water temperature at both inlet and outlet of the long cooling circuit.

Large Format IBM Applications and Market Segments
500ml Pharmaceutical IBM
500ml wide-mouth PP IBM pharmaceutical bottles are the largest standard pharmaceutical container format in Korean, Russian and European markets — used for OTC liquid preparations (cough syrup, antacid suspension, oral rehydration), antiseptic solutions (chlorhexidine, miramistin 500ml hospital dispenser) and nutritional supplement liquid products (multivitamin solutions, mineral complexes at 500ml monthly supply pack). ZQ110 at 6-8 cavities for 500ml PP pharmaceutical IBM produces 2,800-3,600 bottles/hour — sufficient for a 40-50M annual pharmaceutical bottle programme at 2-shift ZQ110 production. Korea Ever-Power supplies ZQ110 machines with pharmaceutical-specific neck finish tooling (38mm wide-mouth, ROPP neck, CRC thread) for the 500ml pharmaceutical IBM application on Korean and global pharmaceutical packaging programmes.
750ml Personal Care IBM
750ml PP IBM personal care containers serve the body wash, shampoo and conditioner category in Korean and Asian retail markets, where 750ml is the preferred family-size unit at Korean supermarket and hypermarket retail (Homeplus, Emart, Lotte Mart). IBM’s pump neck precision (28/410 GPI at ±0.05mm for 750ml lotion pump fitment) and smooth body surface (Ra <0.8μm for heat-shrink sleeve or pad-print decoration without primer) make IBM the quality-preferred process for Korean personal care brands at this format. ZQ110 at 6 cavities for 750ml PP IBM produces approximately 2,700 bottles/hour — yielding 13M bottles/year at Korean 2-shift production, covering one to two major Korean personal care brand programmes at this format from a single ZQ110 investment.
1L Household and Food IBM
1L PP or HDPE IBM containers serve Korean and global household chemical (fabric softener, multipurpose cleaner), food (soy sauce, cooking oil at premium transparent PP IBM for product visibility), and supplement (1L protein shake container, nutritional supplement) applications. Korea Ever-Power ZQ135 at 6-8 cavities for 1L PP IBM produces 2,700-3,200 bottles/hour — the highest output in the ZQ range for 1L IBM. 1L IBM investment case for Korean household brands: domestic ZQ135 IBM supply at 3-5 day Korean lead time versus 60-90 day Chinese or European import supply, enabling Korean household brands at Coupang and Naver online retail to respond to rapid demand spikes without the import inventory buffer cost previously required.

Large Format IBM Quality: Neck Precision and Wall Uniformity
Neck OD at Large Format IBM
Large-format IBM neck OD precision on ZQ110/ZQ135 maintains the same ±0.05mm cavity-to-cavity tolerance as small-format ZQ40 IBM, because the neck injection cavity geometry and injection pressure characteristics are equivalent across the ZQ machine range. The 500ml and 1L pharmaceutical IBM wide-mouth neck (38mm OD) at ±0.05mm OD on ZQ110/ZQ135 satisfies all Korean, Russian (GOST), European (Ph. Eur.) and US (USP) pharmaceutical plastic container neck dimension specifications for standard closure system fitment — a quality outcome that large-format EBM cannot reliably achieve at blown neck ±0.15-0.30mm OD variation.
Wall Uniformity at 500ml–1L IBM
Large-format IBM wall uniformity challenge increases with container height: the PP or HDPE preform must inflate uniformly from top (near neck) to bottom (near base) over a 200-240mm blow height for 1L IBM, versus 80-120mm for 100ml IBM. Korea Ever-Power addresses large-format wall uniformity through preform taper design (injection cavity slightly tapers thicker at the preform base zone to compensate for higher blow stretch ratio at the bottle base) and staged blow pressure (two-stage blow at ZQ110/ZQ135: 2-3 bar pre-blow phase inflates the preform base zone before 7-9 bar main blow completes the full cavity inflation). These design and process measures produce 1L PP IBM body wall variation of ±18-22% from neck to base — within Korea Ever-Power’s large-format IBM wall uniformity specification and superior to EBM large-format ±25-35% wall variation at equivalent format.
Korean and global manufacturers planning 500ml-1L IBM investment can contact Korea Ever-Power for ZQ80/ZQ110/ZQ135 machine selection, large-format mould design consultation, PP and HDPE process pre-validation and annual output modelling.

工程常见问题解答
Large Format IBM — Engineering Questions
Q 01
At what volume does IBM become uncompetitive with EBM on production economics?
The IBM versus EBM production economics crossover point depends on the container application’s quality requirements, but from a pure machine economics perspective the crossover typically occurs at 750ml-1L for commodity containers (no precision neck, no ESCR requirement, no pharmaceutical specification). At 750ml-1L commodity containers (household bleach, generic liquid soap, industrial cleaning solution) where neck OD variation of ±0.20-0.30mm is acceptable, base ESCR is not specified, and wall uniformity ±25-35% is acceptable: EBM’s lower tooling investment (aluminium EBM mould versus steel IBM mould, 3-4x lower cost for same format), higher EBM cavity output at 1L (4-6 EBM cavities run at 2-3s EBM cycle versus 4-6 IBM cavities at 9-10s IBM cycle — EBM produces 2-3x more 1L containers per hour per cavity), and lower EBM machine capital cost make EBM the more economical process for 1L commodity containers. For 1L containers with any of these requirements: precision pump neck, pharmaceutical specification, ESCR-critical formulation, zero-regrind food contact, or surface quality for decoration: IBM on ZQ135 remains the preferred process regardless of the 1L format economics comparison with EBM commodity production. Korea Ever-Power recommends customers apply the IBM-EBM decision framework (quality requirements first, then economics) rather than format volume alone when evaluating large-format container process selection.
Q 02
Can ZQ135 produce 1L IBM containers at economically viable output for Korean household brands?
Yes — ZQ135 at 8 cavities for 1L PP IBM at 9.0s cycle produces 3,200 bottles/hour, or approximately 19.2M 1L bottles per year at 2-shift (16 hours/day) and 300 production days. For Korean household brands (fabric softener, multipurpose cleaner, soy sauce at 1L format) at annual programme volumes of 5-20M units/year, ZQ135 IBM production is economically viable at Korean domestic production economics (Korean PP resin, Korean labour cost, Korean energy cost) versus the alternative of importing 1L containers from Chinese or European IBM suppliers. The IBM quality advantage (zero flash, ESCR base, neck precision for pump or flip-top fitment) is commercially valued by Korean household brands at Coupang and Naver channels where premium packaging differentiation drives consumer conversion rates. ZQ135 investment ROI for Korean 1L IBM programmes is typically 24-36 months at 5M+ annual unit volumes, improving to 18-24 months at 10M+ annual volumes where the machine depreciation cost per container decreases to levels competitive with imported 1L IBM containers at CIF Korean port landed cost plus domestic logistics.
Q 03
What is the mould cost difference between 1L IBM mould on ZQ135 versus 1L EBM mould?
1L IBM mould cost on ZQ135 is significantly higher than 1L EBM mould cost due to the three-component IBM mould architecture (injection cavity set + core rod set + blow mould set) versus EBM’s single-component blow mould. A Korea Ever-Power 6-cavity 1L PP IBM mould set for ZQ135 (S136 stainless injection cavities at Ra 0.025 μm, H13 core rods at 250mm length precision-ground, P20 blow mould cavities) typically costs approximately USD 45,000-65,000 depending on container geometry complexity, label panel features, and neck finish thread detail. A 4-cavity 1L EBM aluminium blow mould for an equivalent round 1L container typically costs approximately USD 8,000-15,000 — 3-6x lower than the IBM mould set investment. The IBM mould cost premium over EBM is justified by: IBM mould life advantage (8-15M cycles versus EBM 3-6M cycles, spreading IBM mould cost over more container cycles); IBM cavity count advantage (6 IBM cavities versus 4 EBM cavities); and IBM quality advantages (neck precision, zero flash, ESCR base) that command premium per-container pricing from IBM-specifying brand customers. For 1L IBM programmes above 20M containers/year, the per-container IBM mould cost amortised over ZQ135 production lifetime is comparable to EBM mould cost per container at equivalent EBM programme volumes.
Q 04
Does Korea Ever-Power offer ZQ110 and ZQ135 with multi-format mould libraries for flexible large-format IBM?
Yes — Korea Ever-Power’s ZQ110 and ZQ135 multi-format mould library service for large-format IBM programmes follows the same architecture as ZQ40/ZQ60 small-format multi-format programmes. ZQ110 and ZQ135 accept multiple large-format mould sets (500ml, 750ml, 1L in both PP and HDPE) via mechanical changeover on the same machine. Changeover time for ZQ110 large-format mould changeover (e.g. 500ml to 750ml): 60-90 minutes mechanical changeover plus 15-20 minutes startup qualification per cavity — longer than small-format ZQ40 changeover (45-60 minutes) due to larger mould set weight and platen access requirements. Korea Ever-Power programmes all planned large-format recipes in ZQ110/ZQ135 HMI at commissioning, enabling production operators to call large-format process recipes by format name from the ZQ HMI recipe library after mechanical mould changeover. For Korean packaging companies running multiple large-format client programmes (pharmaceutical 500ml, personal care 750ml, household 1L) on one ZQ110 or ZQ135, Korea Ever-Power develops a production scheduling template that maximises ZQ110/ZQ135 uptime by sequencing format changeovers by container height order (500ml → 750ml → 1L) to minimise core rod and cooling circuit adjustments between successive format changeovers.
Q 05
What ZQ135 installation requirements differ from ZQ40 for Korean factory planning?
ZQ135 installation requirements for Korean factory planning differ from ZQ40 in three significant areas reflecting the larger machine size, weight and energy demand. Machine footprint and clearance: ZQ135 requires approximately 5.5×2.0×2.3m floor area with 1.5m maintenance clearance on all sides, versus ZQ40 at 3.5×1.3×1.7m. Korean industrial factory planning must allocate minimum 9.5m×5.0m clear floor zone for ZQ135 plus auxiliary equipment (chiller, dryer, conveyor). Foundation and floor load: ZQ135 weighs approximately 18 tonnes (machine + auxiliary), requiring reinforced concrete floor at minimum 5,000 kg/m² bearing capacity. Standard Korean industrial concrete floor (typically 3,000 kg/m²) requires foundation reinforcement under ZQ135 platen footprint before installation — Korea Ever-Power provides ZQ135 foundation load drawing for Korean civil engineering review before site preparation. Electrical supply: ZQ135 operating power at 25-35 kW requires a dedicated 60A three-phase circuit from the Korean factory main distribution board at 380-440V/60Hz. Korea Ever-Power specifies the Korean electrical supply requirement at ZQ135 order, including chiller, dryer and conveyor auxiliary power for the full ZQ135 IBM production system electrical load calculation for Korean factory power planning.
Q 06
What is the ZQ135 lead time for Korean customers and what does factory acceptance testing include for 1L IBM?
Korea Ever-Power’s standard ZQ135 delivery lead time for Korean customers is 90-120 days from order confirmation, including 1L IBM mould set manufacturing concurrent with ZQ135 machine assembly. ZQ135 factory acceptance test (FAT) for Korean 1L IBM programmes at Korea Ever-Power’s Ansan-si facility: the FAT runs the ZQ135 with the Korean customer’s actual 1L IBM mould set and Korean customer-specified PP or HDPE resin for a minimum 4-hour stable production run per mould format (500ml + 1L if dual-format). FAT quality measurements on 1L IBM production: neck OD measurement across all cavities (target ±0.05mm per cavity, ±0.08mm cavity-to-cavity maximum); container weight variation (100 consecutive shots per cavity, target ±1% weight variation); body wall thickness at 6 points per bottle (target wall variation ±20%); drop test on 10 filled containers at 1.2m onto concrete; visual inspection for flow marks, short shots, contamination under 500 lux directional light. Korean customer receives FAT report with all 1L IBM quality measurements before approving ZQ135 for Korean shipping. Domestic Korean ZQ135 delivery from Ansan-si to Korean customer facility: 1-2 day inland freight, with Korea Ever-Power commissioning engineer on-site at Korean factory for ZQ135 installation, foundation check, electrical connection and full 1L IBM production startup qualification at customer factory before production handover.
