HGA.ES-3C76

Fully Automatic Three-Cavity Two-Step PET Stretch Blow Molding Machine for Pharmaceutical Bottles

3 Cavities · 700 ml Max · 3,000 BPH · 68mm Max Body · Korea Ever-Power

Why Choose the HGA.ES-3C76?

✓  3-cavity mid-range output — 3,000 BPH fills the gap between 2-cavity (2,000–2,400 BPH) and 4-cavity (4,000–4,800 BPH) configurations at 76 mm pitch; right-sized for lines where 2-cavity is too slow but 4-cavity exceeds volume targets.

✓  18–38 mm narrow neck range — supports the smallest-mouth pharmaceutical vials in the Medicine Bottle Series; the narrow neck ceiling covers eye drop dropper bottles and precision dispensing vials not suited to wider-neck machines.

✓  ES servo at 76 mm pitch — precise servo-driven stretch-rod control on the compact 76 mm pitch delivers consistent wall distribution at 3,000 BPH for small pharmaceutical vials where wall thickness tolerances are tight.

✓  700 ml max at 76 mm pitch — supports a wider volume range than the AS-4C76.2 (500 ml) on the same pitch; covers standard amber pharmacy bottle sizes up to 700 ml at 3-cavity throughput.

① Only 3-Cavity ES Series Medicine Bottle Machine

The HGA.ES-3C76 is the sole 3-cavity configuration in Korea Ever-Power's ES series medicine bottle range. Its 3,000 BPH output fills the throughput gap between the 2-cavity (2,000–2,400 BPH) and 4-cavity (4,000–4,800 BPH) models at 76 mm pitch — avoiding both under-specification and over-investment.

② 18–38 mm Narrow Neck Specialisation

The 18–38 mm neck diameter range is the narrowest in the Medicine Bottle Series — specifically designed for small-mouth pharmaceutical vials where the narrow neck finish is a defining container specification. Eye drop dropper bottles, nasal spray containers, and precision dispensing vials all fall within this range.

③ 700 ml — Widest Volume on 76 mm Pitch

At 700 ml maximum volume, the HGA.ES-3C76 supports a 200 ml larger volume than the AS-4C76.2 (500 ml) on the same 76 mm pitch. This wider volume ceiling allows the machine to cover small eye drop vials through to mid-size amber pharmacy bottles in a single platform.

④ ES Servo for Small-Vial Precision

Small pharmaceutical vials at 76 mm pitch require precise stretch-rod control to achieve consistent wall thickness in a compact cavity. The ES servo architecture provides exact stretch-rod speed and position control at 3,000 BPH — delivering pharmaceutical-grade wall thickness repeatability across all 3 cavities.

⑤ Efficient 18 kW Normal Heating at 3,000 BPH

18 kW normal operating power for a 3-cavity, 3,000 BPH machine at the 76 mm pitch is efficient for the format scale. Small preform mass at this pitch requires proportionally less infrared energy per preform than larger container formats — the ES zone control matches lamp output precisely, minimising energy waste.

⑥ Compact Machine for 3-Cavity Output

At 2,850 × 1,850 × 2,180 mm and 3,500 kg, the HGA.ES-3C76 is compact for a 3-cavity, 3,000 BPH machine. Its 2,850 mm length is shorter than the 4-cavity AS-4C76.2 (3,370 mm), while delivering 75% of its output — a favourable output-density ratio. An oil-free air compressor is recommended for pharmaceutical-grade production.

35 kg/cm² · 2,400 L/min · Mid-range between 2-cavity and 4-cavity at 76 mm pitch · Oil-free mandatory for pharmaceutical production

8–12 °C · 30 L/min · Standard cooling for 3-cavity 76 mm pitch mold configuration

7 kg/cm² · 1,500 L/min · Higher low-pressure consumption than 2-cavity models to support 3-cavity preform conveying at 76 mm pitch

Why choose 3 cavities over 2 or 4 cavities at 76 mm pitch?

The 3-cavity HGA.ES-3C76 at 3,000 BPH sits between the 2-cavity configurations (2,000–2,400 BPH) and the 4-cavity configurations (4,000–4,800 BPH) on the 76 mm pitch. Choose the ES-3C76 when your annual production volume target is best served by 3,000 BPH — typically 8–11 million units per year at two-shift operation — where a 2-cavity machine would run at very high utilisation and a 4-cavity machine would be underutilised.

What does the 18–38 mm neck range mean for container design?

The 18–38 mm neck diameter range defines the preform neck finish dimensions this machine can accommodate. At 18 mm minimum, it covers small-format eye drop vials and precision dispensing containers with narrow neck openings. At 38 mm maximum, it covers standard small pharmaceutical bottle necks. Containers requiring neck diameters larger than 38 mm require a different machine configuration — the ES-2C100 (68 mm neck) or ES-2C114.3 (88 mm neck), for example.

How does 700 ml max volume compare to other 76 mm pitch machines?

The AS-4C76.2 (4 cavities at 76.2 mm pitch) has a 500 ml volume ceiling. The ES-3C76 at 76 mm pitch supports 700 ml — 200 ml larger on the same pitch. This wider volume ceiling is enabled by the 76 mm pitch's blow cavity geometry and the 240 mm stretching stroke, which accommodates taller containers at this body diameter than the 350 mm stroke of the AS-4C76.2. Confirm your specific container height with Korea Ever-Power against the 240 mm stretching stroke before specifying the mold.

What compressed air system is required?

The HGA.ES-3C76 requires 2,400 L/min at 35 kg/cm² for high-pressure blowing — 60% of the AS-4C76.2's 4,000 L/min at the same pitch. Low-pressure air consumption is 1,500 L/min at 7 kg/cm². An oil-free air compressor is mandatory for pharmaceutical-grade production. Confirm compressor sizing with Korea Ever-Power before installation.

What is the annual production volume at 3,000 BPH?

At 3,000 BPH theoretical output and sustained two-shift operation at 85–92% efficiency, the machine produces approximately 8–11 million bottles per year. This covers mid-scale pharmaceutical manufacturers, regional pharmacy distributors, and contract packagers supplying hospital networks at small-format vial scale.

Does Korea Ever-Power supply 3-cavity molds at 76 mm pitch?

Yes. Korea Ever-Power designs and manufactures 3-cavity blowing molds at 76 mm pitch for the HGA.ES-3C76. Preform injection molds for the small-format 76 mm pitch vial range are also available. Submit your container drawing — body diameter, neck finish, height, volume, wall thickness targets — for feasibility and pricing review.

What after-sales support is provided?

Korea Ever-Power provides on-site installation and commissioning, operator training, a one-year mechanical warranty, remote technical support, and long-term spare parts availability across Malaysia, Indonesia, Peru, Chile, Russia, Philippines, Norway, Morocco, Qatar, and other export markets.

How does the ES-3C76 compare to the ES-4C76 for a buyer choosing between them?

The ES-4C76 delivers 4,800 BPH (60% more than the ES-3C76's 3,000 BPH) at the cost of higher capital investment, a larger footprint, and higher utility consumption. Choose the ES-3C76 when your production schedule is served by 3,000 BPH and the economics of a 3-cavity machine are more favourable than a 4-cavity investment. Choose the ES-4C76 when you need maximum output at 76 mm pitch and annual volume targets justify 4-cavity throughput.

"We produce eye drop vials at 18mm neck and amber pharmacy bottles at 30mm neck on the same machine with mold changeover. The 18–38mm range covers our full vial portfolio on a single platform. 3,000 BPH is exactly right for our production schedule — 4,800 on a 4-cavity would mean running single shifts or overproducing for stock."

HGA.ES-3C76

"The 700 ml volume ceiling was important for us — we run a range from 30ml nasal spray vials up to 500ml and 700ml amber PETG bottles for a hospital contract. The ES servo gives us consistent wall thickness across all three cavities at every bottle size in our range. Korea Ever-Power commissioning team tuned it perfectly."

HGA.ES-3C76

"The 2,400 L/min air requirement at 35 kg/cm² for 3 cavities was straightforward to supply. At 1,500 L/min low-pressure, you need to account for higher preform conveying demand than a 2-cavity machine — Korea Ever-Power advised us on this before installation and we were prepared. Machine runs cleanly with no issues after 8 months."

HGA.ES-3C76

"Good machine for our dropper vial range. Note the 240mm stretching stroke — this limits maximum container height more than other machines in the series. We checked our tallest bottle against this spec before ordering and it was fine, but buyers with tall narrow vials should confirm this carefully with Korea Ever-Power before specifying the mold."

HGA.ES-3C76

"We replaced two ageing 2-cavity machines with one ES-3C76 — the footprint at 2,850mm is actually shorter than our two old machines combined and 3,000 BPH is 25% more than what both old machines produced together. The ES servo quality improvement over the old cam-driven units is significant and measurable on our QC records."
