EP-HGA.ES-6C76 6 Cavities Medicine Bottle Blow Molding Machine
When a pharmaceutical manufacturer needs the maximum output a two-step blow molding machine platform can deliver for standard-format medicine bottles, the EP-HGA.ES-6C76 6-cavity is the answer. At 7200 bottles per hour across six synchronized cavities, this blow molding machine represents the highest production rate in the HGA.ES series and is positioned for high-volume contract packaging operations where the daily bottle count must sustain downstream filling, labeling, and distribution infrastructure at full capacity.
The electrical system draws 62.5 kW at peak and settles to 26 kW in steady production — a 26 kW sustained draw that reflects the thermal demands of conditioning 130 preforms simultaneously for six-cavity continuous output. The high-pressure blowing circuit runs at 35 kg/cm² and consumes 5800 ltr/min to supply six simultaneous blowing events per cycle — the highest air consumption in the series and a utility parameter that must be verified against available compressor capacity before blow molding machine specification.

Six-Cavity Engineering: What Changes at This Scale
Scaling a blow molding machine from four to six cavities is not a linear extension — it requires a systematic reassessment of every sub-system from preform buffer sizing through clamping force distribution, air volume delivery, mold cooling uniformity, and structural mass. The EP-HGA.ES-6C76 blow molding machine addresses each of these requirements as a six-cavity system from the ground up. The result is a blow molding machine platform where six-cavity performance is engineered in, not tuned in after installation.
Mold Engineering
Preform Injection Mold
- The gate lip assembly uses two matched sections that guarantee strict co-axial alignment throughout preform formation — the foundational requirement for producing equal wall distribution across all six cavity positions in this high-output blow molding machine.
- The cooling channel arrangement within the preform mold is calculated to achieve rapid, even heat extraction along the full preform body, maintaining the conditioning rate needed to sustain the 130-position buffer at 7200 bph without thermal variation between early and late-cycle positions.
- All mold forming surfaces are produced from imported 2316 die steel, chosen for its combination of corrosion resistance and the wear hardness that sustained high-cycle pharmaceutical production demands — particularly at the output rates this blow molding machine operates.
- Core plates, cavity plates, and other structural mold elements use 420 stainless steel, providing the corrosion resistance that pharmaceutical production environments — including humid tropical facilities in Colombia and Southeast Asia — require across multi-year production lifespans.
- The modular design supports rapid maintenance access, and standardized interchangeable fittings make scheduled servicing predictable without extended unplanned downtime on a production-critical blow molding machine platform.
- A single mold base can be configured to produce multiple preform specifications, reducing the tooling inventory required when a six-cavity pharmaceutical line carries multiple registered container formats.
Blowing Mold
- Six-cavity blow mold assemblies are machined from premium tool-grade steel selected for the balance of surface hardness and thermal conductivity required to sustain rapid cycle operation across all six positions without accumulating heat that would distort the blown container geometry over a long production run.
- Every container profile is fully validated in 3D CAD modeling before any physical machining begins, confirming that all six cavity positions will produce containers meeting dimensional, label-panel, and base geometry specifications in the digital domain before tooling cost is committed.
- An extensive range of pharmaceutical and personal care bottle profiles is available in our mold library, enabling rapid product introduction onto the six-cavity blow molding machine platform without redesigning mold architecture from scratch for each new container.
- Cooling channels are individually engineered around each of the six cavity perimeters to provide thermally symmetric cooling across all positions — the level of mold engineering detail that distinguishes a blow molding machine platform designed for pharmaceutical GMP compliance from general-purpose alternatives.
- All metal components are finished on CNC multi-axis machining centers to tolerances that ensure complete interchangeability between mold sets across the six cavity positions, supporting validated format changeovers on GMP-registered pharmaceutical packaging lines.
สถานการณ์การใช้งาน
The EP-HGA.ES-6C76 bottle blow molding machine is sized for pharmaceutical manufacturers and contract packagers whose daily bottle volumes justify the capital and utility investment of a six-cavity high-output platform. At 7200 bph, this blow molding machine sustains the production rates required to feed high-speed filling lines across the most volume-intensive pharmaceutical and health product categories. It is the blow molding machine specification that large-scale contract pharmaceutical manufacturers return to when output volume is the primary constraint.
When a Six-Cavity Blow Molding Machine Is the Right Choice
The six-cavity blow molding machine is the highest-output configuration in the two-step pharmaceutical bottle series, and it is the right choice for a specific set of production requirements — not a universal upgrade from four cavities. Understanding when six cavities is justified rather than over-specified saves both capital expenditure and ongoing operational complexity.
Output volume threshold. A six-cavity blow molding machine makes economic sense when your required pharmaceutical bottle output exceeds the sustained capacity of a four-cavity platform — typically above 4000 bph when accounting for line efficiency factors. At 7200 bph theoretical output and approximately 85% operational efficiency, the EP-HGA.ES-6C76 delivers around 6100 bottles per hour in sustained production — the rate required to supply a high-speed pharmaceutical filling line running continuously across two or three shifts per day. Below that threshold, a four-cavity blow molding machine achieves better economics through lower capital cost, lower tooling investment, and simpler quality management.
Container geometry compatibility. The 38 mm neck diameter and 68 mm body diameter of the six-cavity configuration are specifically matched to standard pharmaceutical oral liquid and wash bottle formats. If your container requires a wider neck or larger body diameter, a four-cavity or two-cavity configuration may be more appropriate — adding cavities only helps productivity when all cavities are running the same well-matched container specification. This blow molding machine is a specialist, not a generalist. Any blow molding machine is most productive when matched exactly to the container geometry it was specified for.
Utility infrastructure at the six-cavity scale. The 5800 ltr/min high-pressure air demand at 35 kg/cm², 62.5 kW peak electrical load, and 40 ltr/min cooling water flow are the three utility parameters that must be verified against your facility's capacity before specifying this blow molding machine. Pharmaceutical manufacturers in Colombia, Southeast Asia, and the Middle East should plan dedicated compressor and chiller capacity for this platform rather than drawing from shared factory infrastructure — the demand is too high and too continuous for shared utility systems to sustain without pressure and temperature instability.
Why This Blow Molding Machine
The engineering decisions behind the EP-HGA.ES-6C76 reflect over two decades of practical experience in high-volume pharmaceutical bottle production — not theoretical specifications developed for a catalogue. Every sub-system in this blow molding machine, from the 130-position preform buffer to the six-station cooling manifold, reflects lessons learned from sustained operation on real pharmaceutical production lines, validated against the quality and uptime requirements of regulated packaging environments.
Our pharmaceutical blow molding machine client base includes some of the largest generic pharmaceutical manufacturers and contract packaging organizations across Asia, Latin America, and Europe. These are customers running two and three shift operations where the cost of unplanned downtime is measured in regulatory compliance risk, not just production loss. We supply the blow molding machine, the molds, the auxiliary equipment documentation, and the installation and validation support that these customers need. Every blow molding machine we supply is pre-shipment tested at full production load, with container dimensional data provided to the customer as documented performance evidence rather than specification-sheet projections.
Partner Brands
Containers produced on our blow molding machines reach end consumers through Yibao, Haitian, Luhua, Walch, Blue Moon, Proya, Libai, Estée Lauder, Walmart, Da Senlin, and Shining Eye Drops. These relationships reflect sustained blow molding machine performance across pharmaceutical, cosmetic, and food packaging applications at commercial scale over years, not months.
Recommended Auxiliary Equipment
At six-cavity scale, auxiliary equipment specification is even more critical than on smaller configurations. The 5800 ltr/min air demand, 40 ltr/min cooling water requirement, and six-position mold temperature uniformity all require correctly sized and matched auxiliary systems. We supply a complete matched auxiliary package with the blow molding machine, providing a single accountable supply relationship for the entire production system.
Air Compressor
Oil-free high-pressure compressors rated for 5800 ltr/min continuous delivery at 35 kg/cm². At six-cavity scale, compressor under-specification is the single highest-risk auxiliary error — a pressure drop during blowing on any of the six cavities directly affects container wall distribution and produces defects that appear in downstream inspection rather than during blowing. Correct specification prevents this entirely.
ตัวควบคุมอุณหภูมิแม่พิมพ์
Precision temperature controllers maintaining equal setpoints across all six blow mold cavity positions. At 7200 bph, between-cavity temperature offset of even 1–2 °C compounds into significant batch-level weight variation — the mold temperature controller is the utility device that prevents this systematic quality issue from developing over a long production shift on this blow molding machine.
Bottle Visual Inspection Machine
Six-cavity blow molding machine output at 7200 bph generates a container stream volume that manual sampling inspection cannot adequately cover. An inline automated inspection machine provides 100% detection of wall deviation, contamination, and neck finish nonconformities across the full six-cavity output stream — essential for pharmaceutical container quality assurance at this production rate.
Chiller & Compressor Package
Industrial chillers maintaining 8–12 °C with 40 ltr/min flow for the six-cavity cooling circuit, supplied with oil-free compressor capacity as a verified compatible package. Bundling both utility systems under one supply relationship eliminates the commissioning risk of incompatible cooling and air equipment on a blow molding machine this size.
เกี่ยวกับเรา
Our blow molding machine engineering program started with pharmaceutical-adjacent beverage container production and evolved through progressive engagement with pharmaceutical, ophthalmic, and clinical packaging customers whose requirements forced us to deepen our understanding of multi-cavity quality control, GMP documentation, and the operational realities of continuous production in regulated environments. The six-cavity blow molding machine platform we offer today reflects that accumulated knowledge in concrete engineering decisions — preform buffer sizing, cooling manifold architecture, per-station PLC monitoring — each one traceable to a specific production problem solved on a real pharmaceutical line.

คำถามที่พบบ่อย
Q1. What is the difference between a two-step blow molding machine and a single-stage machine when producing 700 ml pharmaceutical bottles at 7200 bottles per hour?
A single-stage blow molding machine links injection, conditioning, and blowing in a continuous sequence, which means the cycle time of the slowest stage limits the output rate of the entire system. For 700 ml containers, the injection molding stage is slow enough that a single-stage machine cannot achieve 7200 bph from six cavities within a practical machine footprint. The two-step blow molding machine decouples these stages: preforms are produced separately and stockpiled, and the blow molding machine operates on a heating and blowing cycle that is not limited by injection time. This architectural difference is the primary reason that the highest-output pharmaceutical bottle blow molding machines are all two-step designs, regardless of cavity count.
Q2. What air compressor specification does a pharmaceutical plant in Southeast Asia need to install this six-cavity injection blow molding machine without capacity shortfall?
The blow molding machine requires a high-pressure oil-free air supply rated for 5800 ltr/min continuous flow at 35 kg/cm². At Southeast Asian facilities where tropical ambient temperatures reduce compressor volumetric efficiency, size your installed compressor capacity at least 20% above the machine's rated demand — 6960 ltr/min or more — to maintain pressure stability at the compressor outlet under peak summer temperature conditions. The compressor must also be oil-free: any oil carryover into the blowing air circuit of a pharmaceutical blow molding machine produces a direct container contamination risk. We specify the compressor model and installation configuration as part of the blow molding machine quotation package for every project.
Q3. How does the two-stage blow molding process for pharmaceutical PET bottles differ from what single-stage machines can achieve in terms of container wall uniformity?
The two-stage blow molding process allows the preform body temperature to be conditioned to within a tight band — typically ±1–2 °C across the stretch zone — before stretching begins, because the conditioning stage is not time-constrained by the injection cycle. On a single-stage machine, the conditioning time is determined by the overall cycle, not by the preform temperature requirement, which means preforms often enter the blow station with temperature gradients that produce wall thickness variation. At six cavities and 7200 bph, this wall thickness advantage of the two-stage approach translates directly into fewer container failures at downstream inspection and better consistency of fill-to-weight ratio at the filling line — metrics that pharmaceutical manufacturers in Colombia, Southeast Asia, and other regulated markets track as key performance indicators.
