EP-HGA.AS-4C76.2 Medicine Bottle Blow Molding Machine
The EP-HGA.AS-4C76.2 represents an important advance in the field of pharmaceutical plastic bottle manufacturing. Designed on the proven two stage blow molding machine principle, it separates the preform injection stage from the stretch-blow stage, giving engineers independent control over both processes and resulting in far tighter wall-thickness consistency than single-stage machines can achieve. The equipment supports PET, PETG, PC, PCTG, and PP resins — a versatility that makes it equally suited for producing amber medicine bottles, clear eye-drop vials, and hotel-size toiletry containers in a single production run with a mold changeover.
At the heart of the machine is a four-cavity blow mold rated for containers up to 500 ml in volume, with a maximum neck diameter of 48 mm and a maximum body height of 250 mm. The 7 mm small-tooth-mouth mouth design — a first in the domestic market — ensures that even the tightest pharmaceutical neck finish can be produced automatically, eliminating the manual trimming steps common in older bottle blow molding machine designs. Output is rated at 4,000 bottles per hour under standard conditions, placing this unit firmly in the high-productivity segment for pharmaceutical packaging lines across South America, Europe, and Southeast Asia, including Colombia and other high-growth emerging markets.
All critical surfaces and contact zones are manufactured to pharmaceutical-grade standards, with stainless-steel cavity plates and imported die steel preform tooling. The PLC-controlled servo drive system precisely manages clamping force, stretching speed, and blowing pressure, allowing the line to run continuously with minimal operator intervention. Engineers working in pharmaceutical facilities in Colombia or the Netherlands will appreciate how the machine interfaces with existing downstream labeling and filling equipment through standardized conveyor outputs.

Key Advantages of This Blow Molding Machine
7mm Small-Neck Automatic Processing
The proprietary 7 mm small tooth mouth neck design automates what previously required semi-manual trimming. This breakthrough benefits pharmaceutical and eye-drop bottle lines where tight closure tolerances are non-negotiable, and it reduces post-process labor costs significantly across high-volume production environments.
Fully Automatic Operation
This fully automatic blow moulding machine integrates preform loading, heating, stretching, blowing, and unloading in one seamless cycle. The servo-controlled actuators respond to real-time process data from the PLC, stabilizing output at 4,000 bph with minimal deviation — a key advantage for facilities running double-shift pharmaceutical packaging schedules.
Multi-Resin Compatibility
Unlike single-purpose pet blow molding machine lines, this system handles PET, PETG, PC, PCTG, and PP with simple parameter adjustments on the HMI. Switching materials for a new bottle contract takes under two hours, reducing the setup cost that often makes small pharmaceutical bottle runs uneconomical.
Pharmaceutical-Grade Cleanliness
All product-contact zones in the preform and blowing sections are manufactured from 420 stainless steel and 2316 imported die steel, both with hot-treatment finishing. This material selection meets international pharmaceutical packaging standards and supports compliance audits by FDA, CE, and regional equivalents including Colombian INVIMA certification requirements.
Energy-Efficient Heating System
The installed heating capacity of 33 kW steps down to a steady-state draw of 17 kW once the oven zones reach target temperature, cutting energy costs by roughly 48% versus peak. Near-infrared lamps distribute heat evenly around the preform circumference, producing consistent crystallinity and eliminating the cold spots that cause wall-thickness variance in cheaper plastic blow molding machine alternatives.
National Patents & Continuous R&D
More than two decades of dedicated investment in blow molding machine R&D have resulted in numerous registered national patents, covering the clamping mechanism, preform transfer system, and neck tooling geometry. Each production generation incorporates feedback from pharmaceutical clients across South Korea, Brazil, the Netherlands, Australia, and Colombia.

Mold System Overview
Both mold stations in this injection blow molding machine design are engineered independently so that each set of tooling can be optimized for its specific function — preform geometry in the injection station, bottle geometry in the blow station. This separation is a defining characteristic of the two step blow molding approach and is why two-stage systems routinely outperform single-stage designs in dimensional accuracy for pharmaceutical-grade bottles.
Preform Injection Mold
- The die lip is assembled from two complementary sections, maintaining coaxial alignment throughout preform formation for consistent wall distribution.
- Optimized cooling channels shorten each preform cycle and improve demolding consistency, contributing directly to the 4,000 bph theoretical throughput.
- Formation components are machined from imported 2316 die steel — corrosion-resistant and thermally treated — for extended service life in high-humidity pharmaceutical environments.
- Core and cavity plates are fabricated from 420 stainless steel, resisting chemical attack from cleaning agents used in pharmaceutical-grade facilities.
- Tooling layout allows a single mold base to produce more than one preform geometry, reducing changeover investment when adding new bottle sizes to the production range.
Blowing Mold
- Cavity material is selected from high-grade steel hardened to provide consistent surface quality across millions of cycles, making it well-suited for long-run pet blow molding pharmaceutical contracts.
- Three-dimensional CAD modeling drives bottle cavity design, ensuring that every curve and shoulder radius matches the approved container drawing before steel is cut.
- A broad portfolio of standard bottle geometries is available for selection, accelerating time-to-market for customers requiring rapid format introduction.
- Water cooling channels follow bottle contour geometry, removing heat evenly from the blown bottle and shortening the cycle time at the blowing station.
- All metal parts are finished on CNC machining centers, delivering tight positional tolerances on sealing faces, parting lines, and vent slots.
Machine Structure & Design Strengths
The mechanical architecture of the HGA.AS-4C76.2 draws on the same platform used across the broader Medicine Bottle Series, adapted here for the four-cavity configuration. The machine frame is fabricated from heavy steel plate with precision-bored guide columns ensuring that clamping forces remain uniform across all four cavities — a critical requirement when producing pharmaceutical bottles where wall runout tolerances are measured in tenths of a millimetre. The 100 mm clamping stroke and 180 mm mold-close distance are sized to accommodate the widest practical range of pharmaceutical bottle tooling without requiring frame modifications.
The preform heating oven uses independently segmented infrared lamp zones, each controlled by a dedicated PID loop. This means the top and bottom of a tall preform can receive different heat profiles, compensating for the natural tendency of longer preforms to under-heat at the shoulder and over-heat at the base. The result is a blown bottle blow molding output with wall thickness uniformity that meets the rigorous requirements of automated filling and capping lines used by pharmaceutical brands in Colombia, South Korea, and the European market.
Servo-driven actuators replace the hydraulic cylinders used in older machine blow designs, reducing energy consumption, eliminating hydraulic fluid contamination risk, and providing precise, programmable motion profiles for every clamping and opening event. The servo system also enables faster acceleration and deceleration, which directly improves bph throughput compared with pneumatic-only competitors at the same neck-finish specification.
How to Select the Right Blow Molding Machine for Your Application
Choosing the correct blow molding machine format requires matching four core variables to your production requirements: bottle volume, neck finish, resin type, and output rate. The HGA.AS-4C76.2 occupies a well-defined position in the product matrix — it is the right choice when all of the following conditions apply to your project.
Container Volume
Your bottles fall between 5 ml and 500 ml — the ideal window for the four-cavity tooling set.
Neck Finish
Your closure uses a neck diameter of 48 mm or smaller, including the 7 mm small-mouth pharmaceutical finish this machine pioneered.
Resin Type
You process PET, PETG, PC, PCTG, or PP — all are compatible with the oven and stretch-blow parameters.
Required Output
Your line needs 2,000–4,000 bph. For higher volumes, the HGA.AS-4C76.2 can be paired with a second unit for parallel operation.
Regulatory Requirement
Your market requires pharmaceutical-grade surface finishes and material certifications — this machine is built to those standards from the outset.
Two-Step vs Single-Step
When wall thickness consistency ranks above speed of format change, the two stage blow molding machine approach is always preferable to single-stage alternatives for pharmaceutical containers.
If your volume exceeds 500 ml, your neck diameter is wider than 48 mm, or you need more than 6,000 bph, our product range includes larger models from the HGA.ES and HGA.AS series — consult the full specification table to find the matching unit, or contact our engineering team with your bottle drawing for a free recommendation.

This system integrates directly with the conveyor output of the auto blowing machine without interrupting production flow.
Chiller & Industrial Air Compressor
We also supply industrial water chillers and general-purpose air compressors as part of a complete auxiliary package. The chiller maintains cooling water temperature for both mold stations, while the air compressor provides instrument-quality low-pressure air for pneumatic actuators throughout the blow molding machine system.
اکثر پوچھے گئے سوالات
How does a two-stage blow molding machine improve wall-thickness consistency for pharmaceutical PET bottles compared with a single-stage design?
In a two step blow molding process, the preform injection stage and the stretch-blow stage are mechanically separated. This separation allows each station to run at its optimum temperature and speed independently, so the preform arrives at the blowing station with a fully conditioned thermal profile. Single-stage machines must compromise both processes to fit a single cycle time, which results in greater wall-thickness variability — a critical issue for pharmaceutical containers where closure torque and seal integrity depend on dimensional consistency at the neck finish.
Which resin materials is the HGA.AS-4C76.2 automatic pet blowing machine compatible with for producing medicine and eye-drop bottles?
The HGA.AS-4C76.2 supports PET, PETG, PC, PCTG, and PP — the five principal resins used in pharmaceutical container manufacturing. For standard medicine bottles and eye-drop vials the most common choice is PET for clarity and chemical resistance, while PCTG and PC are preferred for applications requiring enhanced impact resistance or specific regulatory compliance profiles in markets like Colombia, the EU, and South Korea.
What is the actual output rate of this fully automatic blow moulding machine when producing 50 ml pharmaceutical bottles with a 7mm neck finish?
The theoretical output is 4,000 bottles per hour across all four cavities. In practice, actual output for 50 ml pharmaceutical bottles with a 7 mm small-tooth-mouth neck finish typically achieves 90–95% of theoretical throughput under stable production conditions, meaning 3,600–3,800 bph is a realistic expectation for a well-maintained line with experienced operators and a correctly tuned oven profile.
How long does it take to change molds on this bottle blow molding machine when switching between different pharmaceutical container formats in a Colombian GMP-certified facility?
Mold changeover on the HGA.AS-4C76.2 is designed for efficiency. The standard interchangeable tooling system means a trained technician can complete a full preform mold and blow mold changeover in approximately 2–3 hours, including the subsequent parameter adjustment and warm-up period. Facilities running GMP-certified lines in Colombia or similar regulatory environments typically schedule changeovers during planned maintenance windows to avoid unplanned production stops.
