EP-HGA.ES-4C76 Water and Beverage Bottle Blow Molding Machine
The HGA.ES-4C76 sits within a purpose-built series of bottle blow molding machines designed to handle multi-pitch, multi-cavity container production across water, beverage, chemical, and pharmaceutical applications. The four-cavity configuration more than doubles the output of comparable two-cavity models while keeping footprint growth moderate — making it the right step up for producers who have outgrown single-pair output but are not yet ready to invest in larger six-cavity platforms. The machine is engineered around a compact 100 mm clamping stroke and a 76 mm bottle mold-close distance, which together define its suitability for the smaller-neck bottle formats common in 250–500 ml still and sparkling water markets.
As a two step blow molding machine, the process begins with preforms — either produced in-house or procured externally — loaded into the machine’s mandrel heating conveyor. Infrared lamp zones bring each preform to its forming temperature profile, after which the stretch-blow station extends the preform axially via servo-driven stretch rod while high-pressure air forces the PET against the cavity walls. The result is a biaxially oriented container with superior gas barrier properties and impact resistance compared to extrusion-blown alternatives. The 4-cavity arrangement means each blowing cycle simultaneously produces four finished bottles, driving the theoretical output to 4,800 bottles per hour at rated conditions.
Container parameters for this model support a maximum neck diameter of 48 mm and a maximum container diameter of 68 mm, with container height capped at 240 mm. These dimensions align well with the 300–700 ml still water, sports drink, and isotonic beverage formats that represent the highest-volume segments in markets including Colombia, Mexico, Brazil, and Southeast Asia. The machine weighs 3,500 kg and occupies a footprint of 3,290 × 1,850 × 2,260 mm — compact enough for standard industrial bays without requiring structural modifications.

Key Advantages of This Blow Molding Machine
Four-Cavity Efficiency
Producing four bottles per cycle is the defining economic advantage of this bottle blow molding machine. Compared to a two-cavity alternative, the HGA.ES-4C76 effectively halves per-bottle machine-time cost while keeping the same operator headcount. For water and beverage producers targeting annual volumes in the 30–100 million bottle range, this output level keeps the line running productively through a full three-shift schedule without overstressing the mechanical systems.
Precision Heating Control
The infrared heating oven features individually adjustable lamp zones across the preform length. With 96 preform holders cycling through the oven continuously, the system maintains steady-state temperature uniformity even when ambient conditions shift — a frequent challenge in warm-climate production environments in Colombia, Brazil, and Southeast Asia. Rated maximum heating power of 40 kW drops to around 18 kW under normal steady-state conditions, reflecting genuine energy discipline rather than specification padding.
High-Pressure Air System
Blowing at 35 kg/cm² with 3,900 ltr/min high-pressure air consumption, the HGA.ES-4C76 produces sharp, well-defined bottle geometry even in designs with deep base insets or label panel recesses. The low-pressure circuit handles pre-blow and pneumatic actuation at 800 ltr/min, keeping the auxiliary air demand well within reach of standard industrial compressor installations. Pairing this pet blow molding machine with a dedicated oil-free compressor is the recommended configuration for food and beverage applications.
Compact Footprint, High Output
At 3,290 × 1,850 × 2,260 mm and 3,500 kg, this fully automatic blow moulding machine delivers 4,800 bph without requiring a large bay footprint. The machine weight and dimensions are typical of what standard industrial floor ratings can accommodate, and the layout allows conventional forklift placement without specialized lifting equipment. This matters significantly for producers fitting a plastic blowing machine into an existing facility alongside filling, capping, and labeling lines.
How to Select the Right Blow Molding Machine for Your Output Target
The right entry point in any blow molding machine selection is annual volume. If your production target sits below 20 million bottles per year, a two-cavity model like the HGA.AS-2C114.3 may match your needs more cost-efficiently. The HGA.ES-4C76 becomes the better choice when volumes push past 30 million annually — or when a single line needs to service multiple SKUs across the 250–700 ml format range without scheduled format changes interrupting throughput. At 4,800 bph, a single shift on this machine produces roughly 38,000 bottles, giving production planners meaningful scheduling flexibility.
Container geometry matters when selecting between different models in this series. The 4C76 designation reflects the four-cavity layout and the 76 mm bottle mold-close distance — a number that directly constrains maximum bottle body diameter to 68 mm. If your range includes wider-body 500 ml format bottles with pronounced grip indentations or large-diameter label panels, this model accommodates them comfortably. For formats pushing beyond 68 mm body diameter, the HGA.ES-4C100 or HGA.ES-4C114 models in the series offer larger mold envelopes.
Infrastructure planning is where projects lose time. The HGA.ES-4C76 needs stable cooling water at 8–12 °C with 40 ltr/min flow, high-pressure compressed air at 3,900 ltr/min, and electrical supply to support 40 kW peak heating. In climates where ambient temperatures routinely exceed 30 °C — common in Colombian, Brazilian, and Southeast Asian facilities — investing in a dedicated industrial chiller rather than relying on ambient-cooled tower water pays back quickly through cycle stability and reduced bottle rejects.
Mold Configuration of Blow Molding Machine
Preform Injection Mold
The die lip splits into two independent sections, each machined to tolerance so the assembled nozzle maintains coaxial alignment throughout the injection stroke — the foundation of consistent preform wall concentricity. Cooling channels are routed to maximize heat removal rate per cycle, shortening the time between injections without sacrificing preform transparency or dimensional accuracy. Forming components are produced from imported 2316 die steel, a grade selected for its combination of corrosion resistance and stable response to heat treatment at processing temperatures. Structural plates — core, cavity, and support elements — are machined from 420 stainless steel, which resists the mild chemical exposure encountered during PET processing and routine cleaning. The mold design prioritizes ease of maintenance: tooling access does not require full disassembly, and fittings follow interchangeable standards. A single mold configuration can accommodate multiple preform neck specifications by swapping standardized inserts, protecting the tooling investment across format changes.
Blowing Mold
Blowing mold bodies are fabricated from premium structural steel chosen for hardness, machinability, and thermal conductivity — properties that together determine both cavity longevity and cycle speed. All bottle profiles are developed in professional 3D CAD software before any machining begins, allowing complex geometry — grip recesses, label panels, base push-up profiles — to be validated digitally and catch dimensional conflicts early. A wide selection of standard bottle designs is available as a starting point, and fully custom geometries can be developed against customer-supplied technical drawings or samples. Internal cooling passages are engineered to distribute fluid flow evenly across the mold surface, maintaining temperature uniformity that prevents asymmetric crystallinity in the finished bottle wall. All metal parts — from cavity inserts to parting line blocks — are finish-machined on CNC equipment to tight tolerances, ensuring repeatable cavity-to-cavity consistency across all four positions in each production run.
Application Scenarios of Blow Molding Machine
Still & Sparkling Water
Water bottle production is the primary application this series was engineered around. The HGA.ES-4C76 produces 250–700 ml still and sparkling water containers with the wall thickness uniformity and base geometry integrity that survive high-speed rotary filling, capping, and case packing without deformation or closure leakage.
Sports & Isotonic Drinks
Isotonic and energy drink formats in the 350–600 ml range often feature grip waist designs and label panel geometry that require precise biaxial orientation to maintain shape under shelf pressure. The stretch-blow process of this auto pet blowing machine achieves the molecular orientation needed for dimensional stability in these formats.
Juice & Cold-Fill Beverages
Cold-filled juice and functional beverage producers value the optical clarity achievable with this pet blow molding process, which lets the product color be visible through the container wall — a key purchase trigger in retail shelf settings. High neck diameter tolerances ensure reliable application of induction foil seals.
Pharmaceutical Liquids
For oral liquid pharmaceutical packaging in the 100–500 ml range, the consistent neck finish dimensions produced by this bottle molding machine ensure child-resistant closure engagement and tamper-evidence integrity across every container in the batch — a non-negotiable requirement in regulated pharmaceutical markets.
Edible Oil & Condiment Packaging
Square-cross-section oil bottles and condiment containers up to 700 ml sit within the machine's container envelope. The ability to handle complex base and body geometry through programmable pre-blow and blowing parameters gives producers flexibility to serve premium retail segments where bottle appearance differentiates the brand.
High-Volume Export Packaging
Contract manufacturers supplying multiple beverage brands across Colombia, Peru, Ecuador, and other Latin American markets find the 4-cavity output of this blow molding machine economical for running multiple SKUs in scheduled production windows — maximizing equipment utilization without dedicating a separate machine to each format.
Machine Structure & Engineering Design
The HGA.ES-4C76 is built on a rigid welded steel base frame with precision-ground guide rails for the clamping station. Four independent blow cavities share a common mold carrier, and the mold opening and closing motion is driven hydraulically with end-stop cushioning to minimize mechanical shock at cycling speeds. The clamping stroke of 100 mm is sized specifically for the 48 mm neck format range, keeping the clamp travel short and the cycle time tight. This is an engineering decision — not a limitation — that directly supports the 4,800 bph output figure under real production conditions.
The infrared preform heating oven accommodates 96 preform holders on the mandrel chain conveyor. Preforms rotate continuously as they travel through the heating zone, ensuring circumferential temperature uniformity before entering the blow station. Lamp zone grouping follows the preform's axial temperature profile requirements, with higher heat input toward the base zone where material needs the most orientation work during the stretching phase. The control system stores multiple heating profiles, allowing quick recipe recall when switching between bottle formats.
Each stretch rod is independently guided, and the blowing valve timing is programmable through the PLC interface — allowing precise control of pre-blow initiation timing, high-pressure blow duration, and exhaust timing. These parameters interact directly with container weight and clarity consistency, and the ability to adjust them per-recipe without mechanical intervention is what allows a single auto blowing machine to cover a range of formats without compromising quality on any of them.

Recommended Auxiliary Equipment
A complete production line around this blow molding machine benefits from purpose-matched auxiliary systems. We supply or recommend the following equipment for direct compatibility with the HGA.ES-4C76 — supporting our commitment to one-stop sourcing and line integration support.
Oil-Free Air Compressor
Beverage and pharmaceutical PET bottle lines require blowing air free of oil aerosols and particulate — a food-safety requirement that rules out conventional lubricated compressors. The HGA.ES-4C76 needs 3,900 ltr/min at 35 kg/cm² for high-pressure blowing; specifying a compatible oil-free air compressor from the outset avoids costly retrofits and keeps the line audit-ready from day one.
Formtemperaturregulator
Maintaining stable mold surface temperature is critical for consistent cycle time and bottle dimensional repeatability. A dedicated mold temperature controller recirculates temperature-controlled fluid through the mold cooling channels at a precise setpoint — eliminating the variability introduced by fluctuating plant water supply temperature. This is especially relevant in warm-climate markets where utility water temperature can shift significantly between seasons.
Bottle Visual Inspection Machine
At 4,800 bph, manual sampling inspection cannot catch every defective container before it reaches the filling line. Automated optical inspection systems check each bottle for wall thickness variations, base clarity, neck finish completeness, and contamination within the blowing station's rejection cycle — protecting downstream equipment from deformed containers and protecting brand quality programs from field escapes.
Industrial Chiller & Cooling System
The HGA.ES-4C76 requires cooling water held between 8–12 °C at 40 ltr/min flow. In markets where ambient temperatures make tap or tower water unsuitable, a dedicated industrial chiller is essential. Stable chilled water supply reduces cycle-to-cycle variation, prevents preform deformation in the heating oven's exit zone, and extends mold service intervals by avoiding thermal shock during production startups.
