EP-HGA.ES-2C114.3 — 2 Cavities Medicine Bottle Blow Molding Machine
The EP-HGA.ES-2C114.3 is a dedicated bottle blow molding machine built around the two-cavity ES platform — a configuration chosen specifically for pharmaceutical manufacturers who need larger bottle formats without sacrificing the dimensional accuracy that injection-blow technology provides. Unlike a standard extrusion blow molding machine, which forms bottles directly from a molten parison, the ES-series uses a true injection-stretch-blow sequence: preforms are injection-molded to a precise neck finish, conditioned through segmented infrared oven zones, and then biaxially stretched and blown to final bottle geometry. The outcome is a container with controlled wall-thickness distribution, excellent drop resistance, and an optically clear body — characteristics that matter most in pharmaceutical and nutraceutical markets.
Supporting a maximum container volume of 1,000 ml and a neck diameter up to 88 mm, this blow molding machine targets the wide-mouth tablet jar segment — one of the fastest-growing packaging formats in Latin American pharmaceutical retail, including Colombia — as well as the standard narrow-neck liquid medicine bottle market. The 114.3 mm bottle mold-close distance provides the cavity depth needed for tall, slender pharmaceutical bottles without requiring a non-standard machine frame. At 2,000 bph theoretical output, the unit is sized for mid-volume dedicated pharmaceutical lines where format flexibility is more valuable than raw throughput.

Key Advantages of This Blow Molding Machine
Wide-Neck Large-Volume Capability
The 88 mm maximum neck diameter and 1,000 ml volume ceiling are rare in the injection blow molding machine segment, where most machines cap out at narrower neck formats. This makes the HGA.ES-2C114.3 the correct choice for pharmaceutical tablet jars, supplement tubs, and wide-mouth dispensing bottles where the lid diameter is a primary design requirement rather than an afterthought.
ES Series Servo Drive Architecture
The ES series replaces hydraulic clamping cylinders with precision servo-electric actuators throughout the clamping and transfer assembly. Servo drives provide repeatable positioning accuracy at every cycle, reduce energy draw during idle phases, and eliminate the contamination risk associated with hydraulic fluid in a pharmaceutical-grade environment. Running steady-state at just 16 kW versus a 50 kW installed capacity, the energy efficiency advantage over comparable hydraulic bottle molding machines is measurable within the first quarter of operation.
Precise PET Biaxial Orientation
The 400 mm stretching stroke delivers the axial stretch ratio that PET and PETG resins need to achieve full biaxial orientation in large-format pharmaceutical bottles. Correct orientation improves top-load strength, barrier performance against moisture and oxygen, and drop resistance — all properties that regulators and pharmacists assess when approving a new pharmaceutical packaging format in regulated markets like Colombia and South Korea.
Consistent Two-Stage Process Control
In a two step blow molding machine design, preforms are produced and conditioned separately from the blow station. This means the oven profile can be tuned independently for each preform geometry, and the stretch-blow parameters can be locked without chasing oven temperature drift — a chronic problem in single-stage machines operating in warm factory environments. For pharmaceutical producers in tropical climates running sites in Colombia or Brazil, this temperature independence is operationally significant.
National-Patent Neck-Finish Technology
Like all machines in the HGA series, the ES-2C114.3 incorporates proprietary neck-finish tooling covered by registered national patents. The tooling geometry ensures that both the preform injection gate and the blow mold parting line land in positions that do not compromise container integrity at the neck sealing face — a critical quality point for child-resistant closures used on pharmaceutical tablet jars in markets worldwide.
Compact Footprint for Dedicated Pharma Lines
At 3,220 × 1,660 × 2,010 mm and 3,000 kg, the machine fits within a standard pharmaceutical cleanroom bay without structural modifications. Its compact plan area allows two units to be installed side by side in a 7-metre-wide production hall — a layout many pharmaceutical CMOs in Australia and Europe use to double capacity while maintaining a single operator supervision point for both blow molding machine cells.

Blow Molding Machine Mold System Overview
The HGA.ES-2C114.3 separates preform production from bottle blowing at the tooling level, which means each mold station can be specified and maintained independently. This structural feature is central to the two step blow molding philosophy: quality is built into both the preform and the blow cavity rather than relying on a single integrated mold assembly to achieve both simultaneously. Below are the key engineering points for each station.
Preform Injection Mold
- The die lip uses a two-part split construction that holds preform coaxiality throughout the injection cycle, preventing the off-center walls that lead to uneven blow ratios.
- Cooling circuit geometry is engineered for maximum heat extraction from each preform, shortening the overall cycle time without pushing crystallinity beyond the acceptable range for stretch-blow processing.
- All mold formation surfaces are machined from imported 2316 die steel, which combines rust resistance with the hardness needed to sustain high injection pressures over millions of cycles.
- Cavity and core plates are produced from 420 stainless steel, selected for its resistance to the condensation and cleaning agents present in pharmaceutical production environments.
- Modular die fitting standards mean that tooling components can be exchanged or upgraded without factory support, keeping maintenance downtime short even in remote facilities.
- Advanced cavity geometry allows one preform mold base to produce more than a single preform variant, which broadens the bottle range a pharmaceutical packer can run on this single auto blowing machine.
Blowing Mold
- Blow cavity material is selected from premium-grade hardened tool steel, providing the surface hardness required for high-volume pet blow molding runs without mid-production re-polishing.
- Container geometry is developed entirely in 3D CAD software before any steel is cut, allowing the design team to verify stretch ratios, corner radii, and label-panel flatness in simulation prior to mold manufacture.
- A broad library of standard bottle profiles is available for selection, accelerating new product introduction for pharmaceutical clients adding SKUs to their packaging range.
- Cooling channel routing follows the outer bottle profile, removing heat uniformly from shoulder to base and preventing the localized hot spots that cause post-blow deformation in large containers.
- Every structural mold component passes through CNC machining centers to meet the tight positional tolerances that parting-line quality and vent-slot alignment require in a pharmaceutical-grade bottle blow molding machine.

Machine Architecture & Engineering Design
The HGA.ES-2C114.3 is built on a heavy-plate welded steel frame with ground-finish guide columns running through the full clamping assembly. The 132 mm clamping stroke and 312 mm mold-open distance give the tooling team the clearance to design tall, complex bottle bodies without compromising ejection. The 60-position preform holder carousel moves finished preforms from the injection station through the conditioning oven to the stretch-blow station in a precisely timed sequence that is fully synchronized by the PLC — meaning there is no operator intervention required between stations during normal production.
The infrared oven section uses independently controlled lamp zones arranged in banks around the preform circumference. Each zone accepts its own setpoint, allowing the oven profile to be shaped differently for wide-body 1,000 ml preforms than for narrower pharmaceutical vial preforms. This programmable profile is what makes the HGA.ES-2C114.3 genuinely multi-format: it is not simply a pet blow molding machine locked to one preform geometry but a configurable platform that accommodates the full product range a pharmaceutical or nutraceutical packer is likely to run over a 10-year equipment lifecycle.
High-pressure blowing air at 35 kg/cm² is delivered through the stretch rod in a coordinated sequence with axial rod travel, ensuring that radial expansion begins at the correct point in the stretch stroke. This coordination is managed by fast-response proportional valves driven by the servo controller, removing the cycle-to-cycle timing variation that causes shoulder wrinkles and base-blush defects in less precisely engineered blowing machine designs. The 400 mm stretch stroke length accommodates the full axial extension that large PET bottles require to achieve the biaxial orientation ratios specified in international pharmaceutical packaging standards.
How to Select the Right Blow Molding Machine for Large Pharmaceutical Bottles
Matching a blow molding machine to a pharmaceutical bottle project is primarily an exercise in aligning five variables: container volume, neck finish diameter, resin type, regulatory requirement, and production rate. The HGA.ES-2C114.3 is the correct starting point when the following conditions describe your project.
Volume Range
You need bottles from 100 ml to 1,000 ml — the two-cavity mold set covers this range with the same machine frame and oven configuration.
Neck Diameter
Your closure requires a neck diameter anywhere from narrow pharmaceutical to 88 mm wide-mouth — a range that covers tablet jars, capsule tubs, and liquid dosing bottles.
Resin Grade
PET for standard bottles, PETG for enhanced impact resistance, PC or PCTG for baby and medical applications, PP for specific chemical resistance requirements — all are supported.
Output Target
Your line needs 1,500–2,000 bph. The two-cavity design produces exactly this range without the overcapacity cost of a higher-cavity unit running at reduced speed.
Two-Stage vs Single-Stage
For pharmaceutical bottles where wall-thickness uniformity affects closure torque values and induction seal adhesion, the two stage blow molding machine route is always preferable — independent process control at each station is the only reliable path to consistent container quality at scale.
Regulatory Market
Facilities supplying FDA, EMA, INVIMA (Colombia), TGA (Australia), or MFDS (South Korea) regulated markets benefit from the material certifications and documentation package supplied with every HGA.ES machine.
If your application calls for more than 2,000 bph or for bottles larger than 1,000 ml, our HGA.ES-2C130, HGA.ES-3C76, or HGA.ES-4C76 models may better match your requirements. Submit your bottle drawing and annual volume to our application engineering team for a formal recommendation.
สถานการณ์การใช้งาน
The large-format, wide-neck capability of this blow molding machine opens it to a range of end-markets that smaller four-cavity machines in the series cannot reach. Below are the primary applications where pharmaceutical producers and consumer healthcare brands specify the HGA.ES-2C114.3.
Pharmaceutical Tablet & Capsule Jars
Wide-mouth tablet containers from 200 ml to 1,000 ml are the primary target for this automatic pet blowing machine. The 88 mm neck diameter accommodates the large child-resistant closures mandated on many OTC tablet and capsule products in North America, the EU, and Latin American markets including Colombia.
Liquid Medicine Bottles
Syrup, oral suspension, and cough-mixture bottles in the 100–500 ml range represent a well-established segment for this pet blow molding machine. The 250 mm maximum container height covers the standard tall-body bottle formats used across Latin American and European liquid pharmaceutical markets, and the PET clarity allows batch number and expiry date printing through the bottle wall without label obscuration.
Nutraceutical & Sports Supplement Containers
Protein powder tubs, vitamin capsule jars, and sports nutrition containers require the same wide-neck, large-volume format as pharmaceutical tablet jars. The nutraceutical market in South Korea and Colombia is growing rapidly, and brand owners increasingly specify injection blow molding machine quality for the surface gloss and dimensional consistency that shelf presence requires.
Veterinary & Agricultural Chemical Containers
Wide-mouth PC and PCTG containers for veterinary oral medications and liquid agricultural chemicals benefit from the chemical-resistance properties these resins provide. The HGA.ES-2C114.3 handles both material types from standard process parameters, and the 1,000 ml volume ceiling covers the bulk packaging formats used in this segment.
Food Supplement & Health Drink Packaging
Functional beverage and health drink brands increasingly use wide-body PET containers that cross over from food packaging into pharmaceutical-level quality expectations. The stretch blow molding machine process used in the ES series delivers the barrier properties and clarity that premium health drink brands specify for their packaging across global retail.
Baby Care & Pediatric Products
Large baby food jars and pediatric liquid medicine bottles in BPA-free PCTG or PC resin are produced at the required quality level on this auto pet blowing machine. The wide-neck format is particularly relevant here because both baby food and liquid pediatric medications are dispensed by parents or caregivers with a spoon, requiring a wide opening for clean, reliable access.

Auxiliary & Related Equipment
Getting the most from a blow molding machine requires that every upstream and downstream system is properly matched. We supply the complete auxiliary equipment package as a single-source delivery, eliminating the integration risk that arises when customers source equipment from multiple vendors. All auxiliary systems are selected and configured to match the specific process requirements of the HGA.ES-2C114.3 — including the 35 kg/cm² high-pressure blowing requirement and the 8–12°C cooling water specification.
Oil-Free Air Compressor
Pharmaceutical and food-contact bottle blow molding operations require oil-free air throughout — both the low-pressure instrument supply and the high-pressure blowing circuit. A dedicated oil-free compressor eliminates the contamination risk that standard lubricated compressors present, and it removes the need for downstream coalescing filters that require frequent maintenance in high-output production environments.
ตัวควบคุมอุณหภูมิแม่พิมพ์
Both mold stations in the HGA.ES-2C114.3 require tightly controlled cooling water supply to achieve consistent cycle times and bottle quality. A mold temperature controller maintains the 8–12°C cooling water setpoint to within ±0.5°C through ambient temperature swings and load changes, which is the only reliable way to keep large-format PET bottle cycle times consistent across a full production shift in a pharmaceutical facility in Colombia or Australia.
Bottle Visual Inspection Machine
Inline visual inspection after the auto blowing machine output conveyor provides 100% defect detection for wall imperfections, neck-finish deviations, and contamination — a requirement in pharmaceutical GMP facilities. Camera-based inspection systems integrated at this point reject non-conforming bottles automatically, removing the batch-hold risk that manual sampling inspection creates for high-volume pharmaceutical packaging lines.
Industrial Chiller & Air Compressor Package
For new facility installations, we offer a pre-configured chiller and compressed-air package sized specifically for the HGA.ES-2C114.3 utility requirements. Combining chiller and compressor supply from a single source simplifies installation engineering and ensures that the utility connections are correctly specified from the outset — avoiding the costly rework that comes from undersized utility supply lines on a pharmaceutical-grade blow molding machine installation.
คำถามที่พบบ่อย
What are the differences between a single-stage and two-stage blow molding machine when producing large-format pharmaceutical tablet jars in Colombia?
In a single-stage machine, the preform is injected and blown in the same cycle without fully cooling between stages, which makes it difficult to achieve uniform wall distribution in large-volume containers like 1,000 ml tablet jars. A two stage blow molding machine like the HGA.ES-2C114.3 cools the preform completely between injection and blowing, then reheats it under precise oven profile control before stretch-blowing — this independent temperature management is what produces the consistent wall thickness that pharmaceutical tablet jars need for reliable child-resistant closure performance in regulated markets including Colombia.
Which resin materials can a fully automatic blow moulding machine in the HGA.ES series process for producing wide-mouth pharmaceutical containers?
The HGA.ES-2C114.3 Blow Molding Machine is validated for PET, PETG, PC, PCTG, and PP. For standard pharmaceutical tablet jars, food-grade PET and PETG are the most common choices because they combine clarity, chemical resistance, and recyclability. PC and PCTG are specified for baby care and pediatric medication applications where BPA-free material certification is required. PP is used when specific chemical resistance or lower processing temperatures are needed for the resin grade in question.
How does the energy consumption of the HGA.ES-2C114.3 automatic pet blowing machine compare to hydraulic blow molding machines of similar output?
The ES series uses servo-electric actuators throughout the clamping and transfer assembly, which reduces idle-phase energy draw dramatically compared to hydraulic systems that maintain constant pump pressure. Once oven zones stabilize at setpoint, total machine power consumption drops to approximately 16 kW steady-state against a 50 kW installed capacity. A comparable hydraulic bottle blow molding machine of equivalent output typically draws 30–40 kW continuously because the hydraulic pump runs at constant load regardless of whether actuators are moving. Over a 6,000-hour annual production schedule, this difference represents a meaningful reduction in electricity cost for facilities in South Korea, Australia, and Colombia where industrial electricity tariffs are significant.
Where can pharmaceutical manufacturers in Australia find a pet blowing machine manufacturer that supplies complete IQ/OQ documentation for GMP validation?
We supply complete Installation Qualification and Operational Qualification documentation packages as a standard option for all HGA.ES series machines delivered to GMP-regulated facilities. The IQ/OQ package is prepared in English and covers equipment identification, utility requirement verification, alarm function testing, and process parameter confirmation against the approved process specification — the standard qualification scope accepted by TGA-regulated facilities in Australia and FDA-registered sites elsewhere. Our application engineering team coordinates the qualification protocol with your validation function prior to machine shipment.
How long does a mold changeover take on this injection blow molding machine when switching between a 500 ml syrup bottle and a 1,000 ml tablet jar in a Colombian pharmaceutical facility?
The standard interchangeable tooling system on the HGA.ES-2C114.3 allows a trained technician to complete a full two-station mold changeover in approximately 2.5 to 3.5 hours, including tooling installation, parameter upload, warm-up, and first-article confirmation. The duration for a 500 ml to 1,000 ml format change is similar to any other changeover because the machine frame and oven length are fixed — only the mold cassettes, preform holder size, and oven profile change. Colombian GMP facilities typically schedule changeovers within planned maintenance windows to avoid unplanned production gaps.
