EP-HGA.ES-3C76 Automatic PET Blow Molding Machine — 700ml, 3 Cavity, Pharmaceutical Bottles

3-Cavity Narrow Configuration

Three cavities at 76mm blow mold close — the only standard RSBM configuration that increases output from the 2-cavity narrow-format baseline without requiring a wider mold close. The 3-cavity arrangement increases output by 50% versus 2-cavity at identical mold close, container geometry, and bottle quality parameters.

3,000 bph Pharmaceutical Output

At 3,000 bottles per hour, the ES-3C76 is positioned for pharmaceutical manufacturers with annual production volumes between 20 million and 30 million bottles in the narrow-neck pharmaceutical format — a production scale that is large enough to justify dedicated machine investment but below the threshold that makes a 4-cavity machine the obvious economic choice.

76mm Narrow-Format Precision

The 76mm blow mold close distance defines the pharmaceutical bottle dimensional envelope: maximum body diameter 68mm, maximum neck diameter 18–38mm across standard pharmaceutical closure formats. This narrow configuration maintains the dimensional precision required for pharmaceutical closure compatibility across PCO, CT, and pharmaceutical-specific neck finishes.

GMP-Compatible Automated Cycle

Zero hand-contact from preform loading to bottle discharge. The sealed automated production cycle satisfies GMP contamination exclusion requirements applicable to pharmaceutical packaging. The machine can be integrated with laminar-flow preform delivery systems and automated transfer conveyors to extend GMP zone coverage across the full production sequence.

Servo-Driven Low Energy Consumption

Servo motors drive all motion axes with digital PLC process management. At 40kW maximum heating power and 18kW common running power, the ES-3C76 delivers 3,000 bph pharmaceutical output at energy consumption significantly below hydraulic-primary RSBM machines of comparable output — a meaningful operational cost advantage over long pharmaceutical manufacturing campaigns.

Digital Parameter Traceability

The PLC system logs heating temperatures by zone, blowing pressure by stage, stretch timing, and cycle count — creating a production parameter record that supports pharmaceutical batch documentation and regulatory audit requirements in GMP-regulated markets including EU GMP, US FDA, and equivalent national frameworks.

Tablet & Capsule Bottles

Standard round tablet and capsule bottles in the 60–500ml range — the dominant pharmaceutical packaging format globally. The 68mm body diameter covers the full range of standard round pharmaceutical tablet bottle diameters from 38mm up to 68mm across all common count formats.

Oral Liquid & Syrup Bottles

Oral liquid medication bottles, paediatric syrup containers, and vitamin liquid supplements in the 100–700ml range. The 240mm maximum container height accommodates tall slim syrup bottles alongside standard proportion pharmaceutical bottles within the same machine configuration.

Application: 200ml, 300ml, and 500ml PET oral antibiotic and vitamin syrup bottles for a Cairo-based generic pharmaceutical manufacturer registered with Egypt’s NARCA.

Problem solved: The manufacturer was running two 2-cavity machines to meet production targets across three bottle sizes — an arrangement that created scheduling complexity and doubled the maintenance load. The ES-3C76 consolidated three-SKU production onto a single 3-cavity machine running at 3,000 bph, reducing the machine count from two to one and cutting the combined maintenance cost by 48% in the first year.

“Two machines into one. Same output, half the maintenance, and production scheduling is now straightforward. The 3-cavity configuration was the right answer for our volume.”

Application: 100ml and 200ml HDPE-equivalent PET tablets and capsule bottles for a Karachi-based OTC pharmaceutical packager serving domestic pharmacy chains.

Problem solved: The packager needed to increase output from their existing 2-cavity narrow machine by at least 40% to satisfy a new supply agreement with a national pharmacy chain — without committing to a 4-cavity machine whose output would significantly exceed contracted volumes. The ES-3C76’s 3,000 bph output represented a 25% increase over their 2-cavity baseline, exactly matching the production uplift required by the new supply contract.

“We needed more output but not too much. The 3-cavity machine hit the number precisely. We didn’t overshoot our contracted volume or under-deliver on the agreement.”

Application: 500ml and 700ml PET vitamin and supplement bottles for a Lagos-based health supplement brand distributing across West Africa.

Problem solved: The brand’s domestic bottle supplier had unreliable delivery lead times — a recurring problem that caused production stoppages. Installing the ES-3C76 in-house eliminated supplier dependency entirely, reduced bottle cost by 22% versus external procurement, and provided the brand with 3,000 bph production capacity to support market expansion into Ghana and Senegal.

“Supply chain unreliability was our biggest operational risk. In-house production with this machine removed that risk completely and gave us the volume to expand into new markets.”
