EP-HGA.ES-6C114 Water & Beverage Bottle Blow Molding Machine

Processing five containers simultaneously per cycle, the HGA.ES-6C114 pushes theoretical output to 5,400 bottles per hour — roughly 70% more than a comparable 3-cavity pet blow molding machine of the same footprint. For water bottling facilities operating two- or three-shift schedules, this throughput gain meaningfully lowers the per-bottle capital cost and creates headroom to absorb seasonal demand peaks without adding a second machine.

A closed-loop servo motor drives the stretching rod to an accuracy of ±0.1 mm per cycle. Because the biaxial stretch ratio directly governs PET molecular orientation — and therefore the bottle's burst pressure, top-load strength, and oxygen barrier — this level of control is not a luxury but a requirement for carbonated-drink and pharmaceutical packaging. The system stores stretch profiles per bottle mold, so switching container formats involves recalling a saved recipe rather than manually re-tuning the axis.

The heating oven divides into multiple independently controlled infrared zones, each with its own power adjustment and air-cooling sub-circuit. This architecture lets operators sculpt a custom heat gradient along the preform body — concentrating energy at the shoulder or base as the bottle geometry demands. Consistent heat input is especially critical when running tall 330 mm containers, where temperature gradients across the preform length would otherwise cause base thinning or top-section over-expansion.

An industrial Siemens or Mitsubishi PLC (customer-selectable) paired with a color touch-screen HMI centralizes monitoring of heating zones, blow pressures, cycle timing, and alarm history. Unlimited mold recipes can be saved and retrieved in seconds, cutting changeover time on this fully automatic blow moulding machine to a fraction of what manual adjustment requires. Remote diagnostics via Ethernet allow technical support teams to access machine logs without waiting for a field engineer to travel to the site.

Dedicated cooling channels cast into the blow mold body circulate chilled water at 40 ltr/min and 8–12 °C, pulling heat from the freshly blown PET wall within each cycle. Rapid cooling locks in the bottle's geometry before it exits the mold, preventing post-blow creep and ensuring dimensional consistency across all five cavities. Paired with an appropriately sized chiller — available as an auxiliary machine from our full-line supply — this system maintains stable cycle times even on extended production runs in warm ambient conditions typical across Colombian and tropical beverage plants.

Two separate air circuits handle pre-blow at 7 kg/cm² and final blow at 35 kg/cm², optimizing the expansion sequence for clean bottle definition and minimal material stress. High-pressure air consumption of 9,500 ltr/min matches the output demands of a 5-cavity auto blowing machine; low-pressure consumption of 1,000 ltr/min manages preform transfer and orientation. Selecting a matched oil-free air compressor — available through our accessories program — ensures no oil contamination reaches the bottle interior, a non-negotiable requirement for food and beverage packaging.

Preform Injection Mold

• The gate lip is structured in two distinct sections, maintaining precise coaxial alignment throughout preform formation and preventing asymmetric wall distribution.
• Cooling water passages are laid out to extract heat uniformly from the preform body, keeping cycle time compact without degrading PET crystallinity.
• All cavity-forming components are produced from imported 2316 die steel — inherently stainless and subjected to controlled heat treatment for extended service life.
• Core plates, cavity plates, and structural load members use 420 stainless steel, ensuring long-term corrosion resistance in humid production environments.
• Standardized interchangeable inserts simplify routine maintenance and allow one mold base to produce multiple preform neck specifications or gram weights.

Blowing Mold

• Mold bodies are sourced from high-grade steel selected for cyclic fatigue resistance under sustained 35 kg/cm² blowing pressure.
• Every bottle cavity profile is developed in advanced 3D CAD software, enabling precise wall-thickness distribution before any cutting begins.
• A broad catalogue of container shapes is available — including round, oval, and custom-label-panel designs — to meet diverse beverage brand requirements.
• Water-cooling channels are routed close to the cavity surface to maximize heat extraction while preserving mold wall rigidity.
• All machined parts are finished on CNC centers to tight dimensional tolerances, ensuring cavity-to-cavity consistency across the full 5-cavity array.

1. What is your target bottles-per-hour figure?

At 5,400 bph theoretical output, the HGA.ES-6C114 suits filling lines running between 3,500 and 5,000 net bph after efficiency allowance. If your line runs slower, a 4-cavity model avoids over-spec; if faster, consider the 6-cavity or 8-cavity range. Matching blow molding machine output to filler speed eliminates costly bottle accumulation upstream.

2. Which container volumes do you produce?

This pet blow molding machine handles containers up to 1,500 ml — covering 350 ml, 500 ml, 750 ml, 1 L, and 1.25 L sizes that together represent the majority of global water and CSD sales. For larger gallons or 5 L containers, a wider-frame model with greater mold-open distance is more appropriate.

3. One-stage or two-stage process?

The two step blow molding process of this machine works best when preform supply is centralized or outsourced. If your facility needs to produce bottles directly from PET resin without a separate preform stage, an injection stretch blow molding machine in a single-stage format may be more suitable — though typically at lower output and higher capital cost per bottle.

4. What utilities are available on site?

The HGA.ES-6C114 needs compressed air at 35 kg/cm², chilled water at 8–12 °C flowing at 40 ltr/min, and electrical supply for up to 72 kW peak. Confirm all three are within reach of your planned machine footprint — 5300×2150×2250 mm — before finalizing installation drawings.

5. How many bottle SKUs do you run annually?

If your operation regularly switches between neck finishes, body shapes, or label heights, look for an auto pet blowing machine with stored mold recipes and a quick-change clamping system. The HGA.ES-6C114 meets this need with PLC recipe storage and a standardized mold mounting interface that reduces changeover to under two hours in trained hands.

💧 Still & Sparkling Water

The most direct application for this blow molding machine is water bottling — both still and lightly carbonated mineral water formats. High output keeps pace with high-speed rotary fillers, while servo-controlled stretch ensures the base of each bottle is thick enough to withstand carbonation pressure without creeping outward on the shelf.

🍹 Juice & Isotonic Drinks

Juice and sports drink producers benefit from the machine's adjustable preform temperature profile, which accommodates the slightly heavier PET gram weights used in hot-fill and isotonic applications. The wide range of available mold designs supports label-panel bottles, grip-waist formats, and wide-shoulder ergonomic shapes popular in Latin American beverage markets.

🥤 Carbonated Soft Drinks

CSD producers running PCO 1881 or other standard closures will find the 68 mm maximum neck diameter and 94 mm body diameter of this plastic blow molding machine align precisely with most mainstream carbonated drink bottle tooling. The servo stretch system delivers the biaxial orientation level needed to meet carbonation retention specifications over a product's shelf life.

💊 Pharmaceutical Liquids

Oral rehydration salts, liquid vitamins, and cough syrup manufacturers operating GMP-compliant lines find that the stainless steel mold construction and contamination-resistant preform transfer system of this blow molding machine match their hygiene requirements. PLC batch recording also supports traceability documentation for regulatory audits.

مولڈ ٹمپریچر کنٹرولر

Precise mold surface temperature directly influences optical clarity and dimensional stability of blown PET containers. Our mold temperature controllers circulate water at the exact temperature setpoint required by the blow mold cooling channels, complementing the machine's built-in chilled-water circuit and extending mold service life by reducing thermal cycling stress on the steel.

Bottle Visual Inspection Machine

At 5,400 bph, manual inline inspection is impractical. An automated vision inspection system placed downstream of this automatic pet blowing machine checks each bottle for wall deformation, surface contamination, and dimensional non-conformity in real time, ejecting rejects before they reach the filler and protecting downstream equipment from misshapen containers.
