EP-HGA.AS-2C114.3 Medicine Bottle Blow Molding Machine
The EP-HGA.AS-2C114.3 blow molding machine brings together advanced injection-stretch-blow technology in a two-station automatic configuration. Unlike conventional bottle blow molding machines that treat medicine bottles as a secondary application, this model was engineered from the ground up to address the unique challenges of pharmaceutical production: sterility concerns, ultra-tight neck tolerances, and consistent material distribution across small-volume, narrow-mouth containers.
The machine adopts a two-step blow molding process in which preforms are independently injection-molded and subsequently reheated before stretching and blowing into their final bottle shape. This two stage blow molding machine approach separates the thermal profiles of preform conditioning and bottle formation, giving operators fine-grained control over crystallinity, haze, and mechanical strength — qualities that are non-negotiable when packaging ophthalmic solutions, syrups, or hospital-grade sanitizers. The plastic blow molding machine platform supports PET and PETG resins, with optional compatibility for PC and PCTG upon mold configuration.
With a machine footprint of 2660 × 1660 × 2150 mm and a total weight of approximately 2600 kg, this blow molding machine is compact enough for mid-scale pharmaceutical plants yet productive enough to sustain an output of 2000 bottles per hour. Its servo-driven clamping system, PLC-controlled heating zones, and closed-loop cooling water circuit combine to produce stable cycle times with minimal operator intervention.

Machine Structure & Key Advantages
What separates the EP-HGA.AS-2C114.3 from a generic automatic pet blowing machine is the depth of engineering embedded in every mechanical sub-system. The injection blow molding machine platform uses a servo-electric clamping unit capable of generating the precise, repeatable clamping force that small-diameter pharmaceutical bottles demand — particularly when neck tolerances must remain within fractions of a millimeter across an entire production run.
Mold Engineering
Preform Injection Mold
- The die lip is formed from two matched components, guaranteeing co-axial alignment during preform formation and eliminating off-center wall distribution in the finished bottle.
- Cooling channels are laid out with computational fluid dynamics principles in mind, shortening cycle time by maximizing heat extraction from the preform before ejection.
- Core functional surfaces are machined from imported 2316 die steel, which combines inherent corrosion resistance with the toughness required for sustained high-cycle pharmaceutical production.
- Core plates, cavity plates, and structural components use 420 stainless steel, ensuring the mold maintains dimensional stability even in humid cleanroom environments.
- Maintenance access is straightforward, and interchangeable standardized fittings reduce spare parts inventory.
- The advanced architecture supports multi-cavity preform variants from a single mold base, providing production flexibility as product lines evolve.
Blowing Mold
- Premium-grade tool steel provides the combination of surface hardness and thermal conductivity that high-speed bottle blow molding requires without premature wear.
- Every bottle cavity is modeled in professional 3D CAD software before any steel is cut, allowing complete digital validation of container geometry, label panel flatness, and base stability.
- A broad library of pharmaceutical and personal care bottle profiles is available, shortening development lead time for new container projects.
- Water channels are positioned precisely around the cavity perimeter to ensure even cooling across all surfaces, preventing warpage and maintaining consistent dimensional conformance.
- All metal components are finish-machined on CNC multi-axis centers, achieving the tolerances and surface finish that make mold-to-mold interchangeability possible.

The EP-HGA.AS-2C114.3 bottle blow molding machine serves a wide spectrum of industries where container integrity, clarity, and contamination control are paramount. Its small-mouth engineering makes it the go-to choice for product types that standard pet blowing machine manufacturers have historically struggled to automate at this output rate.
How to Choose the Right Blow Molding Machine for Pharmaceutical Bottles
Selecting the correct bottle blow molding machine for a pharmaceutical or medical packaging line is not simply a matter of matching output capacity to demand. Several interconnected technical and commercial factors must be evaluated together.
Neck finish size is often the first decision. If your product requires a neck below 10 mm — as is the case with eye drops, ear drops, or nasal sprays — you need a machine specifically engineered for small-mouth production. A standard auto blowing machine designed for water or carbonated beverage bottles simply cannot achieve the tolerances involved. The EP-HGA.AS-2C114.3's 7 mm capability directly addresses this requirement.
Resin compatibility comes next. PET remains the most widely used material for pharmaceutical bottles globally, but PETG offers better drop resistance and lower processing temperatures, making it preferred for pediatric and ophthalmic packaging where sterilization protocols vary. Verify that any pet blow molding machine you consider supports both without requiring significant mechanical changes.
Output rate versus quality stability is a frequent trade-off. A higher-cavity blow molding machine may advertise better bph numbers, but if your product volume is 1000 ml and your neck size is under 15 mm, a two-cavity blow molding machine like this model often delivers more consistent quality per bottle than over-specified four or six-cavity alternatives running at reduced efficiency.
After-sales support and regional service matters enormously for pharmaceutical manufacturers in Colombia, Southeast Asia, and the Middle East, where import lead times for spare parts can halt an entire production line. A manufacturer with documented service infrastructure and locally held key components reduces operational risk meaningfully.

अक्सर पूछे जाने वाले प्रश्नों
Q1. What makes a two-step blow molding machine the right choice for small-mouth pharmaceutical bottle production in Colombia and Southeast Asia?
In a two-step blow molding process, preform production and bottle blowing are completely separate operations. This separation gives manufacturers far greater control over preform reheat profiles, which is critical when working with narrow-mouth containers like eye drop or syrup bottles. For operations in Colombia or Southeast Asian markets where ambient temperatures fluctuate significantly, independent thermal control in a two stage blow molding machine configuration allows operators to compensate for environmental variation without adjusting the injection parameters — protecting both yield and quality on pharmaceutical-grade lines.
Q2. How does a fully automatic blow moulding machine for medicine bottles maintain hygiene and prevent contamination during continuous production?
A fully automatic blow moulding machine eliminates manual preform loading and bottle unloading from the process sequence, which are the two main points of human contact and potential particle introduction in a pharmaceutical blow molding machine environment. The EP-HGA.AS-2C114.3 integrates sealed conveying paths and positive-pressure air circuits that prevent ambient dust ingress into the forming zone. Paired with a closed-loop cooling water system and stainless steel mold components, the machine's design keeps contamination pathways to a minimum — a non-negotiable requirement for ophthalmic and oral liquid container production.
Q3. What types of plastic resins can this injection blow molding machine process, and which one is best for eye drop bottles?
This blow molding machine is compatible with PET, PETG, PC, and PCTG resins. For eye drop bottles specifically, PETG is frequently the preferred choice because it offers excellent transparency, good chemical resistance against aqueous ophthalmic formulations, and easier sterilization at lower temperatures compared to standard PET. PET remains appropriate for many oral liquid and wash product containers. The correct resin selection depends on the active ingredient chemistry, required shelf life, and sterilization method — and our engineering team provides application-specific guidance during the sales and configuration process.
Q4. How do I determine whether a two-cavity or multi-cavity pet blow molding machine configuration is the right fit for my pharmaceutical production line?
The ideal cavity count is determined by the intersection of your required hourly output, your container size, and your quality tolerance. For small-volume containers under 50 ml with narrow neck finishes, a two-cavity blow molding machine typically delivers better per-unit quality consistency than a six-cavity machine operating at partial efficiency. At 2000 bph, the EP-HGA.AS-2C114.3 satisfies mid-scale pharmaceutical production requirements without the mold and setup cost complexity of higher-cavity configurations. If your volumes exceed this range, we can recommend appropriately scaled alternatives from the HGA series.
Q5. Which industries and markets globally are currently adopting stretch blow molding machines for pharmaceutical-grade PET bottle production?
Stretch blow molding machines for pharmaceutical applications are seeing the fastest adoption in Latin America — particularly Colombia, Brazil, and Mexico — as domestic generic pharmaceutical manufacturers invest in their own blow molding machine capacity to reduce import dependency. Southeast Asian markets including Vietnam, Indonesia, and Thailand are similarly expanding PET pharmaceutical container production capacity. In the Middle East and North Africa, hospital group procurement programs are driving investment in locally produced IV solution and oral liquid bottles. European contract manufacturers continue to upgrade from glass to PET for logistical and sustainability reasons. Each of these markets has distinct regulatory and quality standards, and selecting a machine supplier with documented pharmaceutical sector experience is essential for compliant production from day one.
