EP-HGA.ES-4C100 Water & Beverage Bottle Blow Molding Machine
Moving from a two-cavity to a four-cavity blow molding machine is a significant step in production planning — one that changes the economics of every bottle produced on the line. The EP-HGA.ES-4C100 handles up to 800 ml containers across four simultaneous cavities, reaching 4,600 bph under rated conditions. The four-cavity layout also means that any brief downtime event — mold change, routine maintenance, or format switch — affects a larger portion of planned daily output, making machine reliability and fast changeover capability more commercially important than on a smaller platform.
The two-stage blow molding machine architecture underpinning the ES-4C100 separates preform supply from the blowing operation. Preforms with neck diameters up to 68 mm and bodies suited for containers up to 80 mm in diameter and 250 mm in height are fed into the 92-position preform holder carousel, conditioned through the infrared oven, then blown at 35 kg/cm² in a four-cavity blowing station. The 400 mm stretching stroke — longer than the two-cavity models — provides the axial reach needed to achieve consistent PET molecular orientation across container heights up to 250 mm.
EP-HGA.ES-4C100 Water & Beverage Bottle Blow Molding Machine
The EP-HGA.ES-4C100 steps up from the two-cavity ES series to a four-cavity configuration, delivering a theoretical output of 4,600 bottles per hour on a single machine platform. Designed for mid-to-high volume water and beverage packaging lines, this blow molding machine is built around the proven two-stage blowing principle — preforms are loaded, infrared-conditioned, stretched, and blown in a fully automatic cycle that runs continuously with minimal operator intervention. Four cavities per cycle mean higher throughput per square metre of factory floor, lower energy cost per bottle, and faster return on capital for water bottling and beverage production operations across global markets including Colombia, Brazil, and wider Latin America. Whether you are expanding an existing line or setting up a new production site, the EP-HGA.ES-4C100 bottle blow molding machine delivers the output capacity and process consistency that volume-driven beverage packaging demands.

Key Advantages of This Four-Cavity Blow Molding Machine
Scaling from two to four cavities is not simply doubling the output — it changes how the entire production line is planned, staffed, and maintained. The EP-HGA.ES-4C100 Bottle Blow Molding Machine is designed to make that scaling practical: four high-precision blowing cavities running at 4,600 bph, matched to a 92-position preform heating carousel that maintains consistent temperature distribution across all active preform positions simultaneously. The platform uses the same fundamental mechanical and pneumatic architecture as the two-cavity ES models, which means technicians already familiar with the series can service and maintain a four-cavity machine without a steep retraining curve. The advantage cards below cover the core engineering differentiators of this automatic pet blowing machine.
At 4,600 bph, this blow molding machine operates in the upper tier of mid-scale PET bottle production. Four simultaneous cavities maximise throughput while keeping the machine footprint — 5120×2150 mm — significantly more compact than two separate two-cavity lines would require.
The 400 mm stretching stroke — longer than the two-cavity ES models — ensures thorough axial PET orientation in containers up to 250 mm tall. Proper biaxial orientation is directly responsible for the clarity, wall strength, and CO₂ barrier performance of the finished bottle.
The larger preform holder carousel — 92 positions versus 60 in two-cavity models — provides sufficient dwell time in the infrared oven for heavier preforms without requiring reduced line speed, ensuring consistent temperature distribution across all four blowing cavity preforms simultaneously.
Four cavities blowing simultaneously at 35 kg/cm² requires a substantially higher air volume — 4,000 ltr/min at high pressure — than two-cavity machines. The air distribution manifold is engineered for balanced pressure delivery across all four blow nozzles, eliminating cavity-to-cavity volume variation.
Normal operating heating draw is 21 kW against a peak rated capacity of 62.5 kW. This ratio — under 34% of rated — illustrates the efficiency of the zone-controlled infrared system, which adjusts lamp power in real time based on preform temperature feedback rather than running at a fixed output level.
~로서 two-step blow molding machine, the ES-4C100 allows preform procurement to be managed independently of blowing line scheduling. Producers can maintain a preform buffer, source from multiple suppliers, and adjust blowing output without being locked into a synchronised injection-blowing cycle.

Bottle Blow Molding Machine Mold Engineering
At 4,600 bph, mold performance becomes a line-critical variable. A mold that loses dimensional stability at elevated cycle rates, or that requires frequent maintenance interventions, directly erodes the throughput advantage that a four-cavity blow molding machine is designed to deliver. Our preform injection molds and blowing molds are manufactured in-house to standards that match the machine's operating intensity — correct material grades, verified heat treatment, and precision CNC machining throughout.
Preform Injection Mold
- The die lip uses a split two-part construction that maintains precise coaxial alignment between core and cavity throughout each injection cycle, preventing the off-centre gate marks that cause wall thickness variation in the blow phase.
- Cooling passage geometry is engineered specifically for high-throughput cycles — channel routing concentrates cooling at the highest thermal mass zones of the preform, reducing cycle time without extending dwell or slowing line speed.
- All cavity-forming surfaces are machined from imported 2316 die steel, which combines inherent corrosion resistance with strong response to hardening heat treatment — critical for long service life in a production environment with continuous coolant contact.
- Core plates and cavity structural plates are produced from 420 stainless steel, selected for its proven corrosion resistance in wet tooling environments where chilled water circuits run continuously across multi-shift schedules.
- The mold uses a standardised component architecture with interchangeable fittings, so maintenance events are bounded by part replacement rather than specialist mold-fitting work — reducing planned downtime on a high-output line.
- The tooling design supports multi-specification preform production from a single mold set, allowing production schedulers to buffer multiple preform formats against different SKU demand patterns.
Blowing Mold
- Cavity blocks are fabricated from premium tool steel grades selected for hardness, polishability, and dimensional stability under the repetitive thermal cycling inherent in high-speed four-cavity 블로우 성형 production.
- Bottle cavity geometry is defined entirely in 3D CAD/CAM software before cutting, with draft angles, parting lines, and blow ratio verified computationally — reducing the risk of first-article failures and tool modification costs.
- A broad profile library — round, oval, rectangular, grip-panel, and custom brand contours — is available as a starting geometry for new bottle projects, accelerating time from design brief to production-ready tooling.
- Internal cooling passages are routed to balance heat extraction across the full bottle wall area, including base dome and shoulder zones where thermal concentration can cause localised warping in 250 mm-tall containers.
- Every structural and functional component in the mold assembly is finish-machined on CNC equipment, maintaining the sub-millimetre tolerances required for consistent parting-line alignment across a four-cavity set running at 4,600 bph.
Bottle Blow Molding Machine Application Scenarios
With 4,600 bph throughput and a container range covering up to 800 ml, the EP-HGA.ES-4C100 Bottle Blow Molding Machine serves production operations across the water, beverage, food, pharmaceutical, and personal care sectors — anywhere that standard-format PET bottles are required at volume. The following application profiles represent the most commercially active use cases for this pet blow molding machine in global and Latin American markets.
💧 High-Volume Water Bottling
Still and sparkling mineral water in 250 ml to 750 ml formats — the bread-and-butter SKU for regional water bottlers. At 4,600 bph, a single ES-4C100 blow molding machine covers the output of multiple smaller blowing machines, simplifying plant layout and reducing utility infrastructure complexity for water producers in Colombia and across South America.
🥤 Carbonated Soft Drinks
CSD bottle production requires the biaxial orientation that stretch blow molding delivers — the molecular alignment that provides CO₂ barrier performance and pressure resistance in carbonated beverage containers. The 400 mm stretching stroke and 35 kg/cm² blowing pressure on this machine produce the orientation levels that CSD bottles require at the 500 ml and 600 ml sizes most common in retail.
🧃 Juice & RTD Beverages
Cold-fill juice, iced tea, sports drinks, and ready-to-drink coffee in the 300–800 ml range. Container clarity is commercially important in this category because retail buyers make purchase decisions based on product appearance through the bottle wall. The biaxial orientation produced on this automatic pet blowing machine delivers the light transmission characteristics that clear beverage brands require.
🧴 Personal Care Packaging
Shampoo, conditioner, and body wash formats from 200 ml to 800 ml where consistent bottle weight and wall thickness distribution are required for stable filling line performance. Brand packaging teams value the custom contour capability that comes with the mold design process — allowing differentiated bottle shapes without the complexity of an extrusion blow molding tooling approach.
💊 Pharmaceutical Containers
Tablet, capsule, and liquid medicine bottles where PET clarity supports product inspection without container opening, and where neck finish consistency is critical for child-resistant and tamper-evident closure performance. Output at 4,600 bph makes the ES-4C100 viable for contract pharmaceutical packaging operations handling multiple client SKUs on the same platform.
🌿 Food & Condiment Bottles
Ketchup, soy sauce, vinegar, and cooking oil in the 300–800 ml range. PET's combination of clarity, chemical barrier, and lightweight structure makes it the dominant material in these categories globally. The four-cavity output rate on this machine supports the high-volume, fast-rotation production schedules typical of food condiment co-packers serving retail distribution networks.
How to Choose the Right Blow Molding Machine Configuration
The decision to move to a four-cavity blow molding machine from a two-cavity platform is primarily driven by volume requirements and infrastructure capacity. If your production plan calls for more than 2,500 bph on a single machine — and your floor space, air supply, and electrical infrastructure can support the larger system — the ES-4C100 delivers meaningfully lower per-bottle operating cost than running two separate two-cavity machines. The consolidation also simplifies staffing, maintenance scheduling, and quality control process management across the line.
On the infrastructure side, the jump to four cavities brings a proportional increase in high-pressure air demand: 4,000 ltr/min at 35 kg/cm² is the sustained requirement for this pet blowing machine. This means a larger compressor installation — or multiple units in a ring main — and careful attention to air receiver sizing and dryer capacity to ensure moisture-free air reaches the blowing manifold without pressure drop events that cause cavity-to-cavity variation. For Colombian and Latin American production sites operating in high-humidity environments, air treatment system design is a key commissioning variable that directly affects bottle quality consistency. A properly sized chiller delivering 30 ltr/min at 8–12°C to the mold cooling circuit is equally essential.

Compatible Auxiliary Equipment
A four-cavity blow molding machine running at 4,600 bph depends on correctly matched ancillary systems to sustain output quality through extended shifts. We supply and recommend the following equipment as part of a complete production cell solution — each item selected for compatibility with the EP-HGA.ES-4C100's operating parameters.
Oil-Free Air Compressor
Supplying 4,000 ltr/min of clean, dry, oil-free high-pressure air at 35 kg/cm² is the single largest utility requirement of this fully automatic blow moulding machine. Oil contamination in the blowing air is incompatible with food and pharmaceutical-grade PET container production. We recommend a purpose-matched unit from our oil-free air compressor range, sized for this machine's sustained demand with an appropriate safety margin for ambient temperature variation.
금형 온도 조절기
At 4,600 bph, the blowing mold is under sustained thermal stress — four cavities cycling continuously with 8–12°C coolant running through the mold body. A dedicated mold temperature controller holds the coolant supply at a precise set-point regardless of ambient conditions, preventing the gradual mold warm-up that causes wall thickness drift over a multi-hour shift and keeps bottle quality consistent from the first cycle to the last.
Bottle Visual Inspection Machine
At 4,600 bph, manual bottle inspection is not a viable quality control method. An automated visual inspection machine positioned downstream of the blowing machine discharge conveyor screens every bottle for wall defects, gate contamination, short shots, and neck geometry deviations before containers enter the filling station — protecting downstream equipment and ensuring audit-trail documentation for food and pharmaceutical quality programs.
Chiller & Auxiliary Systems
An industrial chiller supplying 30 ltr/min of 8–12°C cooling water is essential for stable mold performance on this auto pet blowing machine. Combined with low-pressure air distribution, conveying systems, and preform feeding equipment, a complete auxiliary package turns the EP-HGA.ES-4C100 blow molding machine into a ready-to-run integrated production cell with minimal on-site commissioning complexity.
자주 묻는 질문
What output rate can a four-cavity automatic pet blowing machine deliver for a high-volume water bottling plant in Colombia or Latin America?
The EP-HGA.ES-4C100 blow molding machine reaches a theoretical output of 4,600 bottles per hour in a standard two-step blow molding cycle. In real-world production — accounting for format-dependent cycle adjustments, preform conditioning time, and standard maintenance events — sustained output typically lands at 85–92% of theoretical rate under well-managed operating conditions. For a water bottling plant in Colombia or across Latin America planning capacity, 4,000–4,200 bph is a reasonable planning figure for a single shift of continuous operation. Two or three shifts multiplies that accordingly, making a single ES-4C100 blow molding machine a viable anchor for a medium-scale regional bottling operation without the complexity of running multiple smaller machines in parallel.
How does a two-stage blow molding machine improve production scheduling flexibility for a beverage packaging operation running multiple PET bottle formats?
The key scheduling advantage of a two-stage blow molding machine is that preform production and bottle blowing are completely independent operations. Preforms for several different bottle formats can be produced or purchased in advance, sorted by format, and stored in a climate-controlled area until the blowing station is scheduled for that SKU. The blowing line then runs at full speed for each format run without waiting for the injection unit to catch up. Format changes on the blowing station — involving a mold swap and heating profile recall — can be completed in a few hours, after which full-rate production resumes immediately.
Which compressor specification does a four-cavity pet blow molding machine operating in a humid tropical climate actually need to run reliably?
The EP-HGA.ES-4C100 requires sustained high-pressure air delivery at 4,000 ltr/min and 35 kg/cm². In high-humidity tropical environments — typical of Colombia, coastal Brazil, and much of Central America — the compressor package must include a properly sized refrigerant air dryer capable of achieving a pressure dewpoint of at least -20°C to prevent moisture from reaching the blowing manifold. Moisture in the high-pressure circuit causes water marks inside PET bottles, disrupts preform temperature distribution by cooling the blow air, and accelerates corrosion in pneumatic valves. Compressor sizing should include a minimum 15–20% output reserve above rated machine demand to account for ambient temperature effects on compressor delivery capacity.
What are the main differences between single-stage and two-stage blow molding when producing 500 ml and 800 ml PET beverage bottles at industrial scale?
For 500 ml and 800 ml standard beverage bottles at industrial production volumes, two-stage blow molding generally delivers a lower cost per bottle than single-stage for several structural reasons. Single-stage machines link the injection and blowing cycle on one platform, which means the overall cycle rate is constrained by whichever operation is slower — typically the injection phase for heavier preforms. Two-stage machines like the ES-4C100 remove this constraint entirely: the blowing station cycles independently of preform supply, maintaining full four-cavity output as long as conditioned preforms are available. Two-stage also allows preform procurement to be managed as a supply chain variable — buying preforms from multiple qualified suppliers during price-competitive periods — whereas single-stage ties preform production to the machine running time.
