HGYS350-V4-EV Full-Servo ISBM Machine — Alternative to AOKI AL-350LL

The HGYS350-V4-EV is a made-to-order full-servo large-capacity machine configured to the customer's container specification and AOKI AL-350LL mould drawing. Full technical parameters — injection capacity, screw speed, clamping forces, mold stroke, machine dimensions, and weight — are confirmed during the mould compatibility review. Contact Korea Ever-Power with your AOKI AL-350LL mould drawings and container specification for a complete machine data sheet within 5 working days at no charge.

The Precision Case

At the 350-class injection ceiling, the preform weights required for large pharmaceutical liquid bottles, wide-body food containers, and precision cosmetic dispensers are substantially heavier than small-format containers. A 0.8–1.5% shot-weight variation — typical for pump-servo or hydraulic machines — means heavier absolute mass variation per cavity. This translates directly into wall-thickness variation visible across cavity positions, and in pharmaceutical applications, into neck-finish dimensional drift that affects closure torque and leak compliance across a production shift. The HGYS350-V4-EV's full-servo closed-loop injection holds variation below 0.3% regardless of preform weight — maintaining wall-thickness consistency at the 350-class injection ceiling that pump-servo platforms at this scale cannot achieve.

The Productivity Case

Full servo drives eliminate the hydraulic pressure build-up and release delay at the start and end of every injection event. At the 350-class scale — where injection cycles are longer and cycle times are measured against higher production targets — the compound effect of removing that hydraulic latency per cycle is larger than at small-format scale. The HGYS350-V4-EV runs at a uniform screw speed across all screw diameter configurations (same as HGYS150-V4-EV's uniform 350 rpm), shortening plasticising per cycle and reducing total cycle time relative to a pump-servo machine at equivalent injection volume. On a high-value large-format production line running 2 or 3 shifts, the recovered cycle time accumulates into a measurable output advantage per production year on the same AOKI AL-350LL mould set.

Pharmaceutical Liquid Packaging — Large-Volume Precision Containers

Large-volume pharmaceutical liquid containers — IV solution bottles, parenteral nutrition containers, and large oral liquid dispensers — where neck-finish dimensional tolerance determines filling-line reject rates and closure torque compliance at scale. The HGYS350-V4-EV's full-servo closed-loop injection holds shot-weight variation below 0.3% per cycle across all cavity positions at the 350-class injection ceiling, maintaining wall-thickness consistency that pump-servo machines at this scale cannot achieve through a sustained production shift. The AOKI AL-350LL has historically been the reference machine for this application class; the HGYS350-V4-EV carries the same mould tooling forward with a higher injection ceiling and full-servo precision.

Precision Cosmetic and Premium Personal Care — Large-Format Dispensers

Large-format PETG cosmetic dispensers, premium lotion bottles, salon-size personal care containers, and professional-grade packaging for premium beauty brands where optical clarity and wall-thickness uniformity across all cavity positions are brand requirements at large-container scale. The nano far-infrared heated barrel maintains PETG barrel temperature uniformity that is critical for optical clarity consistency in large-body PETG containers — where localised barrel temperature variation is more visible in the finished bottle than in small-format containers. Full-servo axis control prevents the cavity-position variation that pump-servo machines accumulate across a sustained production shift on large-format PETG.

Food-Grade Large-Format Containers — Edible Oil and Condiment Precision Packaging

Large PET and PETG containers for premium edible oil, high-value condiments, and food-grade liquid products where the brand proposition includes container clarity and consistency — the retail-shelf differentiation that PET one-step ISBM delivers over extrusion blow-moulded alternatives. The full-servo architecture delivers the wall-thickness uniformity and neck-finish precision that food-grade liner-sealed closures require at the AL-350LL container scale. Food-contact regulatory documentation available on request.

Q1: Can my existing AOKI AL-350LL mould tooling be used directly on the HGYS350-V4-EV?

Yes. The HGYS350-V4-EV platen is designed to match the AOKI AL-350LL mounting standard. Submit your AL-350LL mould drawings for a written compatibility review and full machine data sheet within 5 working days at no charge. Korea Ever-Power confirms exact platen stroke values, adapter requirements if any, and injection capacity suitability for your specific container format during the review.

Q2: Why are full specifications not published on this page?

The HGYS350-V4-EV is a made-to-order machine configured to each customer's container specification and AOKI AL-350LL mould drawing. Exact injection volume, screw speed, clamping forces, mold stroke, machine dimensions, and weight are confirmed against the customer's tooling and container requirements during the compatibility review — not against a fixed catalogue specification that may not match the customer's mould. This is standard practice for large-capacity full-servo ISBM machines across the industry. Korea Ever-Power issues a full machine data sheet with the compatibility review, at no charge, within 5 working days of receiving the mould drawings.

Q3: What is the practical advantage of full-servo over pump-servo at the AL-350LL capacity scale?

At the 350-class injection ceiling, preform weights are substantially heavier than small-format containers. A 0.8–1.5% shot-weight variation — typical for pump-servo machines — means heavier absolute mass variation per cavity, producing visible wall-thickness variation across cavity positions that affects filling-line reject rates on pharmaceutical and precision food containers. The HGYS350-V4-EV's full-servo closed-loop injection holds variation below 0.3% regardless of preform weight. Additionally, full servo eliminates hydraulic pressure latency per cycle, shortening cycle time and improving bottles-per-shift output on the same AOKI AL-350LL mould set.

Q4: How does the HGYS350-V4-EV compare to the HGYS150-V4-EV?

Both machines share the same full-servo architecture — independent closed-loop servo motor per functional axis, shot-weight repeatability below 0.3% per cycle, uniform screw speed across all screw diameter options, and nano far-infrared heated barrel. The HGYS150-V4-EV is the ASB-12M class machine for precision small-to-mid-format containers (20 ml to 2,500 ml); the HGYS350-V4-EV is the AL-350LL class machine for precision large-format containers. Choose HGYS150-V4-EV if your tooling follows the ASB-12M mounting standard; choose HGYS350-V4-EV if your tooling follows the AOKI AL-350LL mounting standard.

Q5: What is the delivery lead time for HGYS350-V4-EV?

45–75 working days from order confirmation and deposit. As a made-to-order large-capacity full-servo machine, HGYS350-V4-EV typically falls in the 65–75 day range within that window due to servo motor integration, servo calibration, and large-format platen assembly requirements. A production milestone schedule is issued with each order confirmation.

Q6: Is on-site commissioning and operator training included?

Yes, for Korea and SEA customers. A Korea Ever-Power engineer installs the machine, mounts the AOKI AL-350LL mould tooling, and runs first-production samples to specification before departure. Operator training covers full-servo parameter setup, daily maintenance, process optimisation for large-format containers, and fault diagnosis — all on-site in the same visit.

Q7: What materials does HGYS350-V4-EV process?

Standard: PET and PETG including rPET. The nano far-infrared barrel is particularly beneficial for PETG optical clarity and mechanical consistency at large-container sustained production rates. For PP, PC, Tritan, or engineering resins at AL-350LL scale, contact Korea Ever-Power with the specific resin datasheet — screw, barrel, and heating system configurations are reviewed against the resin thermal window as part of the compatibility review.

Q8: What spare parts availability looks like post-purchase?

5-year availability commitment for consumable and wear parts. Inovance / WEICHI servo motors, NSK lead screws, Parker valves, and YUKEN hydraulic valves are stocked by regional distributors in Korea and SEA for same-day or next-day availability. A recommended spare parts kit specific to large-capacity full-servo machine operation ships with each machine at commissioning.

Q9: What warranty applies to HGYS350-V4-EV?

12-month parts warranty from commissioning sign-off. Structural components carry a 3-year warranty. Remote diagnostic support within 4 business hours. Engineer dispatch within 5 business days for hardware faults not resolvable remotely — priority response for this machine class given the production-volume and product-value impact of downtime.

Q10: What certifications does HGYS350-V4-EV carry?

CE marking and ISO 9001:2015 are standard on all HGYS350-V4-EV machines. CE Declaration of Conformity is available for review before order confirmation. Full machine data sheet and factory acceptance test report on buyer-specified resin and container format are supplied at delivery.
