7 mm Ultra-Narrow Neck — Industry First

The ES-3C76 is the first domestically developed fully automatic stretch blow molder capable of producing containers with neck diameters down to 18 mm (with 7 mm capability available) — enabling automated production of eye-drop bottles, nasal-spray vials, and precision-dosage pharmaceutical containers that previously required manual or semi-automatic processes.

No-Hand-Contact — GMP Compatible

Fully automated preform feed, oven conveying, blow cycle, and bottle discharge means no operator hand contact with preforms or bottle interiors at any production stage — satisfying the fundamental GMP requirement for primary pharmaceutical packaging material and supporting HACCP and BRC compliance submissions at filling facilities.

AS-Grade Servo Precision

AS-series models use higher-specification servo motors and precision reducers delivering ±0.03 mm stretch-rod positioning accuracy — exceeding standard ES-series performance for pharmaceutical bottles with complex asymmetric geometries, fine-pitch neck finishes for child-resistant closures, or premium bottle profiles requiring tighter dimensional tolerances than standard packaging applications.

1,800 to 7,200 bph — Full Range

From 2-cavity 1,800 bph platforms for specialised pharmaceutical brands through to 6-cavity 7,200 bph lines for mass-market nutraceutical and supplement production — the series covers the full throughput range of pharmaceutical and healthcare bottle manufacturing without the need for multiple machine types.

PET & PETG — Pharmaceutical Grade

Both PET and PETG are globally approved for direct pharmaceutical contact. PETG offers superior clarity and glossiness for premium oral-care and supplement presentations. Both materials are processed without hardware modifications — oven zone profiles and PLC recipes for each material are stored on-board, enabling rapid changeover between resins for different product categories.

★ ES-3C76 Note: Neck diameter range 18–38 mm covers the ultra-narrow-neck segment including 7 mm capability for eye-drop bottle production — the first domestically developed fully automatic machine for this format. Specialised narrow-neck preform mandrel and transfer system fitted as standard.

🛠 Machine Frame & Clamping

Heavy-gauge welded steel frame, stress-relieved and CNC-machined at all guide-rail and bearing surfaces. Toggle-link servo-electric clamping with no hydraulic fluid — eliminating contamination risk in pharmaceutical production environments and extending maintenance intervals. The AS-series clamping mechanism incorporates higher-specification bearings and guide rails than the ES series, supporting the tighter dimensional tolerances required for pharmaceutical neck-finish production.

⚙ Narrow-Neck Mandrel System (ES-3C76)

The ES-3C76 features a precision narrow-neck mandrel and preform transfer system designed specifically for neck diameters of 18–38 mm. Standard pharmaceutical blow molder handling systems cannot accommodate necks below 28 mm without preform jamming or misorientation. The ES-3C76 mandrel geometry prevents these failures at production speeds up to 3,000 bph.

🌡 Pharmaceutical-Grade NIR Oven

Multi-zone NIR quartz-lamp oven with independently controlled zones and a pharmaceutical-grade neck-protection cooling collar. Pharmaceutical preforms span a wide wall-weight range — from ultra-light 1 g eye-drop vial preforms to heavier 50 g oral liquid bottle preforms — requiring individual zone configuration for each application. All oven enclosures are smooth-surface and cleanable, compatible with pharmaceutical facility cleaning protocols.

🔓 Pharmaceutical Mold Materials

Blow mold cavities machined from high-strength aluminium alloy with 3D CAD conformal cooling channels. Pharmaceutical bottle molds incorporate precision child-resistant neck-finish tooling (28 mm CRC, 38 mm CRC, and custom formats) machined to ±0.01 mm on the neck-finish geometry — tighter than standard packaging applications. Preform injection molds use imported 2316 mold steel with 420 stainless cavity plates, CNC-machined to ±0.02 mm.

📱 PLC, Batch Logging & Traceability

Siemens or Mitsubishi PLC with colour HMI touchscreen. Up to 50 bottle-format recipes on-board. The pharmaceutical-grade configuration includes production batch logging — recording output count, cycle time, and oven zone data per batch — supporting the production traceability documentation required by pharmaceutical filling facility quality systems (GMP, ISO 13485).

📈 Inline Rejection System

All non-conforming containers are automatically rejected before the downstream conveyor. In pharmaceutical filling lines where off-specification bottles cause closure failures, fill-level inaccuracy, or leakage, the inline rejection system provides the pre-filling quality gate required by GMP-compliant primary packaging operations.

Yes. The fundamental GMP requirement for primary pharmaceutical packaging is that no operator hand contacts the packaging material interior during production. All models in this series achieve this through fully automated preform feed, oven conveying, blow cycle, and bottle discharge — with no manual handling at any stage. We can provide machine architecture documentation confirming no-hand-contact production for inclusion in pharmaceutical Quality Management System submissions (GMP, ISO 13485, BRC).

Eye-drop bottles require neck diameters of 7–18 mm — significantly narrower than the 28 mm minimum neck that standard pharmaceutical blow molder handling systems can process. The ES-3C76 features a precision narrow-neck mandrel and transfer system purpose-built for 18–38 mm neck diameters (with 7 mm capability available), enabling fully automatic production of eye-drop and nasal-spray containers at 3,000 bph — replacing semi-automatic or manual production methods that introduce contamination risk and output variability.

AS-series models use higher-specification servo motors and precision reducers delivering ±0.03 mm stretch-rod positioning accuracy versus ±0.05 mm for standard ES-series models. This additional precision is required for pharmaceutical bottles with complex asymmetric geometries, fine-pitch child-resistant closure neck finishes requiring tighter engagement torque tolerances, or premium bottle profiles where dimensional deviation would cause visual or functional quality failures in downstream filling and closure application. For standard oral liquid and tablet bottles without special geometry requirements, ES-series models are fully adequate for pharmaceutical production.

Yes. Both PET (Polyethylene Terephthalate) and PETG (Glycol-modified PET) are globally approved for direct pharmaceutical contact under USP Class VI, FDA 21 CFR, EU Regulation 10/2011, and equivalent national pharmacopoeia standards for aqueous formulations. PETG offers superior clarity and surface gloss for premium pharmaceutical presentations. Neither material requires food-contact or pharmaceutical-contact certification of the machine itself — the material certification applies to the resin grade used for preform production.

All models require low-pressure air at 7 kg/cm² and high-pressure air at 26–35 kg/cm². For pharmaceutical bottle production, ISO 8573-1 Class 1 oil-free air is mandatory at the high-pressure blowing point — hydrocarbon oil mist from a non-oil-free compressor would contaminate the bottle interior and constitute a GMP failure. We supply matched pharmaceutical-grade oil-free high-pressure compressor packages as part of our turnkey solution.

Yes. Child-resistant closure compatibility requires the bottle neck-finish to be machined to ±0.1 mm diameter tolerance for consistent CRC engagement torque. AS-series models achieve ±0.05 mm neck-finish tolerance — exceeding the CRC requirement. ES-series models achieve ±0.2 mm — adequate for standard CRC applications. Mold designs for specific CRC neck finishes (28 mm, 33 mm, 38 mm, 45 mm CRC standards) are available with dimensional validation reports on request.

Yes. The pharmaceutical-grade PLC configuration includes batch logging that records output count, reject count, cycle time data, and oven zone power data per production batch. This data supports the manufacturing batch record documentation required by pharmaceutical GMP quality systems. Data export via USB or Ethernet is available. Full electronic batch records with electronic signature (21 CFR Part 11 compliance) can be configured on request for regulated pharmaceutical facilities.

Standard ES-series and AS-series machines are produced within 45–60 working days from deposit receipt. Pharmaceutical blow molds for confirmed 3D bottle designs are delivered in 30–40 working days — slightly longer than standard packaging molds due to the tighter dimensional tolerances and CRC neck-finish geometry. Preform injection molds take 40–55 working days. Factory acceptance testing with bottle samples and dimensional measurement reports is conducted before shipment.

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. Documentation confirming no-hand-contact no-hydraulic-fluid architecture is provided for pharmaceutical GMP qualification submissions. IQ/OQ (Installation Qualification / Operational Qualification) protocol documentation is available for pharmaceutical facility qualification requirements.

Yes. All models include an inline bottle conveyor with standard interface dimensions compatible with downstream filling, stoppering, capping, induction sealing, and labelling equipment. For pharmaceutical filling lines requiring enclosed transfer between blow molder and filler (to maintain container cleanliness), enclosed conveyor tunnel options are available. Line-speed matching calculations and buffer conveyor sizing recommendations are provided at the project planning stage.
