HGA.ES-4C76

4-Cavity Enhanced Servo Stretch Blow Molding Machine  ·  PET / PETG  ·  4,800 bph  ·  Max 68 mm Body  ·  CE + ISO 9001:2015

The HGA.ES-4C76 is the highest-output machine in the HGA.ES series at 76 mm pitch — delivering 4,800 bph across four simultaneous cavities for slim cosmetic and daily chemical bottle production up to 700 ml. The enhanced servo drive is the critical specification for 4-cavity production: with four bottles produced per cycle, inter-cavity timing precision has a fourfold amplified effect on production uniformity compared to single-cavity machines.

In 4-cavity production, each cycle produces four bottles simultaneously. Any timing deviation in blow sequence, stretch rod advance, or take-out propagates across four positions per cycle — producing systematic inter-cavity weight and wall-thickness variation that accumulates across the production run. The ES enhanced servo's faster response and tighter positional repeatability suppress this inter-cavity timing variance at its source — making the ES drive configuration a production quality specification, not merely a cycle speed specification, at 4-cavity scale.

At 4,800 bph, the HGA.ES-4C76 delivers 60% more bottles per hour than the 3-cavity 3C76 (3,000 bph) and 20% more than the 4-cavity AS-series machine at the same pitch (4,000 bph). For high-volume shampoo, conditioner, body wash, toner, and daily chemical filling lines where slim-bottle output is the production constraint, the 4C76 provides the highest available throughput within the 76 mm pitch slim-format category in the HGA ES series.

The 48 mm maximum neck diameter on the HGA.ES-4C76 is 10 mm wider than the 3C76's 38 mm limit — and matches the neck range of the standard-servo HGA.AS-4C76.2. This wider neck range covers the pump-top dispenser closures, sports-cap formats, and wider flip-top closures used in daily chemical and personal care slim bottles that the 3-cavity model cannot produce. If your bottle requires a neck diameter between 38 mm and 48 mm, the 4C76 is the correct 76 mm pitch ES selection.

The 96-position preform holder is the largest in the HGA.ES 76 mm pitch series — providing the extended infrared heating dwell time required to maintain consistent through-wall temperature conditioning for four simultaneous preform streams at peak output. With 96 holder positions advancing four preforms per cycle, each preform receives substantially more infrared residence time than on a 42-position (3C76) holder at comparable cycle speed — the key factor for consistent wall-zone temperature targeting across all four cavities.

At 4,800 bph and slim cosmetic bottle volumes of 100–500 ml, the HGA.ES-4C76 produces 480,000 to 2,400,000 ml of container volume per hour — the highest volumetric throughput available in the HGA.ES slim-bottle range. For high-volume cosmetic filling operations and daily chemical production where per-unit packaging cost is a primary commercial driver, the 4-cavity ES configuration provides the best output per machine footprint in the slim-bottle ES category.

4-cavity commissioning at 76 mm pitch requires calibration of the 96-position preform holder indexing, infrared zone balancing across four simultaneous preform streams, ES servo parameter setup for 4-position blow station timing, and systematic inter-cavity uniformity verification from all four positions. Ever-Power's commissioning engineers handle all four aspects before handover, supplying first-production samples from all four cavities inspected against inter-cavity weight and dimensional uniformity specifications.

Standard and premium shampoo, conditioner, and body wash in PET and PETG from 200 ml to 700 ml at slim bottle formats up to 68 mm body diameter. The highest-volume personal care filling lines require 4-cavity output to meet production targets at the per-shift bottle count that fast-moving consumer goods supply chains demand. Both pump-top (up to 48 mm neck) and standard-closure slim formats are within the 4C76 specification.

Slim PETG toner, essence, and serum bottles from 100 ml to 500 ml for high-volume K-beauty and cosmetic brand clients. OEM packaging suppliers serving multiple concurrent brand clients at high combined volume benefit from 4-cavity output — the 4,800 bph rate allows multiple brand SKUs to be completed within standard production windows. PETG clarity maintained consistently across all four cavities through ES servo timing precision and zone-level infrared zone control.

Hand sanitiser, liquid soap, dishwashing liquid, and household personal hygiene products in PET from 200 ml to 700 ml at slim bottle body diameters. The 48 mm maximum neck diameter covers the wider pump-top dispensers standard in daily chemical personal care formats. High-volume daily chemical filling lines where slim-bottle output is the production bottleneck — the 4-cavity 4,800 bph configuration resolves the constraint without format change.

OEM packaging suppliers producing maximum-volume slim-format PET and PETG bottles across multiple cosmetic and daily chemical brand clients — where 4,800 bph per machine and consistent inter-cavity quality across four positions allows the highest per-machine output with the ES quality standard that premium cosmetic clients require. The 4C76 is the most productive single-machine option in the HGA.ES slim-bottle category.

"We run shampoo and conditioner from 200 ml to 600 ml at 65 mm body diameter for FMCG clients. The HGA.ES-4C76 at 4,800 bph is the right machine for our output targets. We had a standard-servo 4-cavity machine before — the switch to ES made a measurable difference in inter-cavity weight uniformity. Cavity 1 and cavity 4 used to show a consistent weight gap; with the ES drive, that gap is gone across extended production runs."

Machine: HGA.ES-4C76

"We produce slim PETG essence and toner bottles at 120 ml and 200 ml for multiple K-beauty brand clients. The 4-cavity output at 4,800 bph lets us service concurrent client orders efficiently within a single shift. PETG clarity across all four cavities has been consistent — the 96-position holder gives each preform enough heating dwell time for reliable zone conditioning. Commissioning team was thorough in setting up the PETG infrared profile."

Machine: HGA.ES-4C76

"We manufacture hand sanitiser and liquid soap at 300 ml and 500 ml in PET with 48 mm pump-top neck — the 48 mm neck was the reason we needed the 4C76 rather than the 3C76. Output at 4,800 bph suits our daily chemical filling line schedule. The machine footprint at 3,290 mm length fits our production bay without the floor layout issues we had with longer 3-cavity machines."

Machine: HGA.ES-4C76

"We operate two HGA.ES-4C76 machines for our OEM slim-bottle production line serving five cosmetic brand clients simultaneously. 4,800 bph per machine with consistent inter-cavity quality gives us the throughput and quality level our premium clients require. One recommendation: have your preform supplier confirm that the preform design is matched to 4-cavity running at 76 mm pitch before commissioning — we had an early preform issue that added time to our startup."

Q1: What is the difference between the HGA.ES-4C76 and the HGA.ES-3C76?

Both machines use 76 mm pitch and cover bottles up to 68 mm body diameter and 700 ml. The 4C76 adds a fourth cavity, increasing output from 3,000 bph to 4,800 bph (+60%), expanding the neck diameter range from 38 mm to 48 mm, and providing 96 preform holder positions versus 42. Choose the 4C76 when maximum slim-bottle output is the priority, or when your bottle requires a neck diameter between 38 mm and 48 mm. Choose the HGA.ES-3C76 when 3,000 bph suffices and process simplicity at 3-cavity scale is preferred.

Q2: Why is the low-pressure air consumption lower on the 4C76 than on the 3C76?

The low-pressure air system powers preform conveying, cooling air circuits, and mold actuation. The HGA.ES-4C76 at 800 L/min versus the 3C76 at 1,500 L/min reflects a more efficient low-pressure circuit design in the 4-cavity mechanical layout — the 4C76's preform transport path and cooling circuits are configured for lower low-pressure air demand despite the higher cavity count. This is not an error: verify the specification against the Ever-Power technical documentation for your specific configuration if planning utility infrastructure.

Q3: Can PETG be run at 4-cavity production rate on this machine?

Yes. The 96-position holder and zone-level digital infrared system provide the dwell time and temperature control precision PETG requires at 4-cavity rate. The key requirement is that each of the 4 preform streams receives consistent heating across its zones — the large holder capacity ensures this at 76 mm pitch even at 4,800 bph cycle rate. Zone profiles are calibrated for your specific PETG grade during commissioning. Contact Ever-Power with your PETG datasheet before ordering for a zone profile assessment.

Q4: What is the machine footprint?

3,290 mm (L) x 1,830 mm (W) x 2,260 mm (H), 3,500 kg. The 4C76 is notably more compact than the 3C76 (5,570 x 2,090 x 2,500 mm) despite having four cavities versus three — the 4-cavity layout at 76 mm pitch is mechanically more efficient in footprint than the 3-cavity layout at the same pitch. Allow lateral clearance on both sides for mold change-over and space for the bottle outlet conveyor and auxiliary equipment.

Q5: What certifications does the machine carry?

CE marking and ISO 9001:2015 are standard on all HGA series machines. CE Declaration of Conformity available before order. Factory acceptance test report with samples from all four cavities inspected for inter-cavity dimensional and weight uniformity supplied at delivery.

Q6: What after-sales support is available?

Remote technical support during business hours. 5-year spare parts availability commitment. On-site engineer dispatch for faults not resolvable remotely. The 4-cavity ES commissioning engineer is available for follow-on site visits if inter-cavity uniformity issues arise during production ramp-up that are not resolvable through remote parameter guidance.
