AS-Grade Precision — All 5 Models

Every model in this series uses AS-grade servo motors and precision reducers — the only blow molding series where AS-grade precision is standard across all configurations, not a premium upgrade option. This reflects the irreducible precision requirement of non-standard bottle geometry, where standard servo machines produce commercially unacceptable surface quality on complex cross-sections.

PETG — Crystal Clarity for Decorative Bottles

PETG delivers visibly superior surface clarity, gloss, and scratch resistance versus standard PET — the difference is commercially significant for premium perfume, spirits, and decorative packaging where glass-like clarity is a purchase driver. PETG also offers better dimensional accuracy on fine-detail mold geometries due to lower processing shrinkage. All models support PETG via stored dual-mode PLC recipes.

38 mm to 114.3 mm — Full Neck Range

The series spans the full neck-diameter range encountered in specialty packaging — from 38 mm miniature perfume and cosmetic vials (AS-4C38) through 76 mm premium spirits formats (AS-2C76, AS-4C76) to 114.3 mm wide-mouth decorative jars (AS-1C114.3, AS-2C114.3). Five models cover every major specialty packaging neck standard without cross-series compromise.

PET vs Glass — Weight, Safety, Cost

Stretch-blown PET and PETG deliver glass-like clarity at 60–70% lower weight — reducing shipping cost and breakage risk across luxury retail distribution. For premium spirits and perfume brands, PET/PETG irregularly shaped bottles eliminate the glass-breakage liability in travel retail, e-commerce fulfilment, and gift packaging while maintaining the visual sophistication that premium consumers expect.

Sub-Millisecond Blow Timing Control

The AS-grade servo’s sub-millisecond blow-timing precision minimises differential face-seating stress on non-cylindrical molds — the root cause of stress marks on multi-faceted bottle designs. This enables successful production of hexagonal, oval, square-shoulder, and compound-curve bottle geometries that consistently fail on standard servo platforms.

Complete Turnkey Supply

We supply irregularly shaped blow molds (including multi-faceted, oval, hexagonal, and bespoke geometry tooling), PET and PETG preform injection molds, industrial chillers, and oil-free compressor packages from a single source — with DFM review before mold construction to verify stretch-ratio feasibility and wall-thickness distribution for each custom bottle geometry.

⚙ AS-Grade Servo System

All five models use higher-specification AS-grade servo motors, precision harmonic reducers, and servo drives — delivering ±0.03 mm stretch-rod positioning accuracy and sub-millisecond blow-valve timing control. These specifications are mandatory for irregular geometries, not optional upgrades. The mechanical drive train is engineered to maintain positional accuracy across the full production speed range, preventing the position drift at elevated cycle rates that causes dimensional variation on complex bottle geometries.

🛠 Rigid Frame for Complex Mold Loads

Irregularly shaped bottle molds generate asymmetric clamping forces across the platen face — unlike cylindrical bottle molds where clamping load is evenly distributed. The AS-series machine frame and platen are designed with additional rigidity at the non-symmetric loading points, preventing platen deflection that would cause parting-line flash on irregular cross-section molds.

🌡 Decorative Surface NIR Conditioning

Decorative bottle preforms often have complex wall-profile distributions to pre-position material for differential stretch zones. The multi-zone NIR oven with individually controlled zone power provides the axial thermal gradient customisation required to heat irregular-profile preforms to the correct stretch temperature at each axial position simultaneously. Zone configurations for each bottle format are stored as PLC recipes — ensuring reproducible thermal conditioning across production campaigns separated by weeks or months.

💉 PETG-Mode Optimisation

PETG requires lower blowing temperatures and benefits from faster cooling versus PET to maximise surface gloss and minimise crystallisation haze. All models store dedicated PETG-mode oven profiles, transfer timing, and cooling duration settings as separate on-board recipes — enabling consistent high-gloss PETG surface finish production without empirical parameter searching at each format changeover.

🔓 Decorative Mold Tooling

Irregularly shaped blow molds are machined from high-strength aluminium alloy using 5-axis CNC with surface finish Ra ≤ 0.4 μm on all visible bottle surfaces — the standard required for glass-substitute decorative packaging. Conformal cooling channels follow the complex mold cavity geometry, ensuring uniform cooling across all facets of non-cylindrical bottle profiles and preventing the thermal asymmetry that causes post-mold bottle warping. We offer DFM (Design for Manufacturability) review before mold construction at no charge, verifying stretch-ratio feasibility and preform design for each custom geometry.

📱 PLC & Dual-Mode Recipes

Siemens or Mitsubishi PLC with HMI. Up to 50 bottle-format recipes stored on-board, including separate PET-mode and PETG-mode sets. Irregular bottle producers typically run multiple SKUs (different bottle silhouettes for different product lines or seasonal editions) — the on-board recipe storage enables same-day format changeover without manual parameter reconstruction.

In a cylindrical mold, radial resistance is uniform around the cross-section — all faces seat on the mold wall simultaneously. In a non-cylindrical mold (hexagonal, oval, faceted), radial resistance is differential — flat faces seat earlier than curved faces, and convex faces seat last. If high-pressure blowing is applied before all faces have seated, the last-seating faces receive excessive stress, causing visible stress marks or unacceptable wall thinning. The AS-grade servo’s ±0.03 mm stretch-rod accuracy and sub-millisecond blow-timing control minimise this differential seating time gap — enabling wall uniformity on complex geometries that fails consistently on standard servo machines.

PET and PETG are both crystal-clear packaging materials, but PETG offers measurably higher surface gloss (approaching glass-like levels), better scratch resistance, and higher impact toughness at equivalent wall weight. PETG also has lower processing shrinkage — typically 0.2–0.4% versus 0.3–0.6% for PET — providing better dimensional accuracy on fine-detail mold geometries including embossed surfaces, sharp shoulder angles, and textured body panels. For premium perfume, spirits, and cosmetic packaging where visual surface quality is a purchase driver, PETG is the preferred material. PET is generally specified where cost and oxygen barrier (slightly better in PET) outweigh the surface-quality advantage.

The series handles the full range of non-cylindrical specialty bottle geometries that can be produced by stretch blow molding, including: oval and elliptical cross-sections, hexagonal and octagonal profiles, square-cornered and rectangular cross-sections, tapered waist and hourglass profiles, asymmetric shoulder geometries, compound-curve body panels, and embossed surface patterns. The practical limit is stretch-ratio feasibility — any bottle geometry where the maximum local stretch ratio in the preform exceeds material limits will produce wall thinning or fracture regardless of machine precision. We assess stretch-ratio feasibility for each custom geometry at DFM review stage before mold construction.

Submit your 3D bottle drawing (STEP or IGES format) for a DFM (Design for Manufacturability) review. Our engineering team will assess: (1) maximum body-to-neck ratio — extreme oversizing of the bottle body relative to preform neck may exceed biaxial stretch limits; (2) minimum corner radius on sharp features — very small corner radii (below 3–5 mm) concentrate wall thinning; (3) undercut geometry — true undercuts cannot be released from a two-part blow mold without side-action complexity; (4) surface detail depth — deep embossing requires careful preform material positioning. DFM review is at no charge and typically returns within 3–5 working days.

Yes, in most packaging and distribution contexts. Stretch-blown PET and PETG deliver glass-level clarity at 60–70% lower weight, with complete elimination of breakage risk. Key considerations: spirits with high alcohol content (above 50% ABV / 100 proof) may experience slight flavour migration through PET over extended storage — PETG provides better resistance and a barrier coating option is available for high-ABV formats. Carbonated spirits require a CO² barrier layer. For premium still spirits, cordials, liqueurs, and all food applications, standard PET/PETG is fully suitable for shelf lives of 24+ months. We can advise on material and barrier options for specific formulations at enquiry stage.

Decorative blow molds for this series are machined to Ra ≤ 0.4 μm surface finish on all visible bottle surfaces — the standard required for glass-substitute premium packaging. This finish transfers directly to the bottle surface through the blow molding process, producing a high-gloss appearance in PETG and a premium-clarity finish in PET. Textured surface panels (sand-blast, bead-blast, or machined pattern textures) can be applied to specific mold zones to create contrast between gloss and matte surface areas on the same bottle — a popular technique in premium spirits and fragrance packaging.

Complex irregular-geometry blow molds require 40–55 working days from approved 3D drawing — longer than standard cylindrical bottle molds (25–35 days) due to 5-axis CNC machining of complex cavity surfaces, multi-region conformal cooling channel design, and extended surface polishing time to achieve Ra ≤ 0.4 μm on non-planar surfaces. DFM review (3–5 days) precedes mold construction and is included at no charge. First-article inspection samples with dimensional measurement reports are provided before production molds are shipped.

Each bottle SKU (different geometry, volume, or neck finish) is produced with its own blow mold and stored as a separate PLC recipe covering oven zone powers, transfer timing, blow pressure, and cooling duration. Changing between SKUs requires mold substitution (35–50 minutes) and recipe selection on the HMI. All format-specific parameters are restored automatically from the stored recipe — no manual oven or pressure adjustments. Up to 50 recipes are stored on-board, covering the full range of SKUs typical of a multi-format specialty packaging operation.

All machines are CE-marked and carry multiple national utility model patents. ECM verification certificates for electrical components are available. Country-specific certifications (UL, EAC, INMETRO, etc.) can be supported subject to additional testing. For food-contact and cosmetic applications, documentation confirming no-hydraulic-fluid servo-electric architecture is provided. PET and PETG material compliance documentation (FDA, EU Regulation 10/2011) is obtainable from resin suppliers for specific grades used in preform production.

Standard AS-series machines are produced within 45–60 working days from deposit receipt. Irregular-geometry blow molds are delivered in 40–55 working days from approved 3D drawing — this lead time runs concurrently with machine production for projects where the bottle design is finalised at order placement. Preform injection molds for custom irregular preform profiles take 45–60 working days. Factory acceptance testing with bottle samples and surface measurement reports is conducted before shipment. On-site commissioning typically requires 3–5 working days per machine.
