HGA.AS-4C76.2 Cosmetic & Daily Chemical Bottle Blow Molding Machine

HGA.AS-4C76.2

4-Cavity Automatic Blow Molding Machine  ·  PET / PETG  ·  4,000 bph  ·  Max 65 mm Body  ·  CE + ISO 9001:2015

Four simultaneous cavities at 76.2 mm pitch deliver 4,000 bottles per hour — double the output of a 2-cavity machine on the same production footprint. The 76.2 mm pitch is the standard for mainstream cosmetic and personal care bottles in the 30 ml to 300 ml range, making this machine directly compatible with the dominant tooling standard in the industry without pitch adapters or custom preform design.

The 96-position preform holder provides extended residence time in the infrared heating zone per cycle. Longer dwell time allows the digital infrared system to bring each preform to precise blow temperature with greater consistency — directly improving PET bottle wall-thickness uniformity and reducing cycle-to-cycle variation in cosmetic bottle optical clarity.

A digitally controlled infrared heating system with zone-level power control maintains uniform preform temperature across all 96 holder positions. Consistent preform temperature at the blow station is the primary variable controlling wall-thickness distribution and optical clarity in cosmetic and daily chemical bottles. The system controls this precisely every cycle at 4,000 bph output rate.

International-brand servo motors and reducers throughout the drive chain deliver precise position control and repeatable mold stroke accuracy at sustained 4,000 bph output. Standard operating heating power of 17 KW against a 33 KW maximum keeps energy cost per bottle competitive at high throughput — typically 20–30% lower electrical draw per unit than constant-speed motor alternatives at equivalent output.

The stretch-blow process delivers biaxially oriented molecular structure for superior drop resistance and optical clarity in premium cosmetic formats. Asymmetric, multi-faceted, and special-shaped cosmetic bottles — the formats that demand precise preform temperature control and consistent stretch ratios — are produced with consistent wall distribution at 4,000 bph throughput.

Internationally sourced servo motors, electrical components, and control systems follow standard industrial specifications for local spare part sourcing. The machine is designed for practical serviceability — components accessible, diagnostics readable through the control interface, maintenance intervals predictable — minimising unplanned downtime in continuous multi-shift cosmetic production.

The high-volume core of premium cosmetic production — serum vials, toner bottles, essence dispensers, and facial mist sprayers from 30 ml to 200 ml in PET and PETG. The 76.2 mm pitch is the standard for these formats. Four-cavity output at 4,000 bph supports single-machine production of full filling-line volumes without running multiple units in parallel.

Facial cleanser flip-top bottles, standard lotion dispensers, and body wash containers from 100 ml to 500 ml in PET and PETG. The 65 mm maximum body diameter covers the standard form factor for this product category — including round, oval, and softly faceted profiles — across K-beauty, J-beauty, and international personal care brand specifications.

Travel-size personal care containers, hotel amenity bottles, and baby care packaging from 50 ml to 300 ml. The 48 mm maximum neck diameter and standard bottle heights up to 250 mm cover the dominant packaging formats in the personal care and baby care sectors. PETG for clarity-critical baby lotion and cream formats; PET for standard personal care dispensers.

Waisted, faceted, multi-panel, and geometrically distinctive K-beauty cosmetic bottle formats with demanding surface-quality requirements. The stretch blow process at 76.2 mm pitch delivers consistent wall distribution across asymmetric profiles at 4,000 bph — formats where this process outperforms conventional rotary blow alternatives in surface definition.

Blowing pressure: 35 kg/cm² · Min. flow: 4,000 L/min (higher than 2-cavity model) · Oil-free type recommended for cosmetic packaging

"We run the 4-cavity machine on our serum and toner bottle line — 120 ml and 200 ml PET formats. Output has been consistently close to 3,900 to 4,000 bottles per hour on both formats. Wall thickness is uniform across all four cavities. We have been running two shifts since installation in Q3 2023 without any significant issues."

Machine: HGA.AS-4C76.2

"We upgraded from an older 2-cavity machine to the 4-cavity Ever-Power unit. Throughput doubled on the same floor space. The 96-position preform holder was specifically what our process engineer wanted — longer heating dwell for our PETG grade. Clarity on the finished bottles is excellent."

Machine: HGA.AS-4C76.2

"Surface quality on the special-shaped cosmetic bottles was our primary requirement — asymmetric waist profile bottles for an export client. The stretch blow process delivers that reliably. Setup time on a new mold is reasonable. We would have liked slightly faster mold change-over, but the bottle quality meets our client's specification consistently."

Machine: HGA.AS series

"We produce PETG personal care bottles for export — 150 ml and 250 ml formats. Optical clarity and dimensional precision are non-negotiable. The Ever-Power machine meets both consistently. The support team helped dial in the preform temperature zone profile for our PETG grade during commissioning. Over eight months of two-shift operation without production-stopping issues."

Machine: HGA series

Q1: What is the difference between HGA.AS-4C76.2 and HGA.AS-2C114.3?

The HGA.AS-4C76.2 has 4 cavities at 76.2 mm pitch, delivering 4,000 bph for standard cosmetic bottles up to 65 mm body diameter and 500 ml volume. The HGA.AS-2C114.3 has 2 cavities at 114.3 mm pitch, delivering 2,000 bph but with a wider 94 mm maximum body diameter and 1,000 ml maximum volume. Choose the 4C76.2 for higher throughput on standard-size cosmetic bottles; choose the 2C114.3 for wider-body lotion pumps, large cream jars, and large daily chemical containers.

Q2: Why does the 4-cavity machine require more high-pressure air than the 2-cavity model?

Each cavity performs a full blow cycle per rotation. With 4 cavities blowing simultaneously at 35 kg/cm², the total high-pressure air consumption is proportionally higher — 4,000 L/min for the 4-cavity HGA.AS-4C76.2 versus 1,600 L/min for the 2-cavity HGA.AS-2C114.3. When specifying an air compressor for the 4-cavity machine, use 4,000 L/min as the minimum continuous delivery capacity at 35 kg/cm².

Q3: What bottle formats does the HGA.AS-4C76.2 produce best?

Optimised for PET and PETG cosmetic and personal care bottles from 30 ml to 500 ml with a maximum body diameter of 65 mm and neck diameter of 48 mm — serum vials, toner bottles, essence dispensers, facial cleansers, lotion bottles, travel-size personal care containers, and baby care packaging. The 76.2 mm cavity pitch is the standard for these formats globally.

Q4: Can the machine handle PETG for premium cosmetic bottle production?

Yes. The 96-position preform holder and zone-level digital infrared heating system provide the extended dwell time and precise zone control that PETG requires for optical clarity. PETG has a narrower thermal processing window than standard PET — the longer preform residence in the 96-position holder (versus a shorter holder) gives the heating system more time to bring each preform precisely within that window. Contact Ever-Power with your specific PETG grade for a preform temperature zone profile before ordering tooling.

Q5: What preform specification is compatible with this machine?

The machine accepts standard PET and PETG preforms for containers up to 500 ml volume, 48 mm neck diameter, and 65 mm body diameter. Ever-Power's technical team can review your existing preform design or recommend a specification for a new container format. A mold design consultation is recommended before ordering tooling for a new bottle profile at 76.2 mm pitch.

Q6: What is the machine footprint and how does it compare to the 2-cavity model?

The HGA.AS-4C76.2 has a footprint of 3,370 mm (L) x 1,850 mm (W) x 2,100 mm (H) and weighs 4,000 kg — larger than the 2-cavity HGA.AS-2C114.3 (2,660 x 1,660 x 2,150 mm, 2,600 kg) but delivers twice the output at 4,000 bph versus 2,000 bph. For factories where output per square meter is the primary optimisation target, the 4-cavity machine delivers a better output-to-footprint ratio on standard cosmetic bottle sizes.

Q7: What certifications does the machine carry?

CE marking and ISO 9001:2015 are standard on all HGA series machines. CE Declaration of Conformity is available for review before order. Factory acceptance test report on buyer-specified preform and container format is supplied at delivery. Additional regulatory documentation available for pharmaceutical or food-grade packaging applications on request.

Q8: Is on-site commissioning included?

Yes for domestic customers. A factory-trained engineer handles installation, mold mounting, process parameter setup, and operator training at the customer facility before handover sign-off. Remote technical support is available during business hours. Spare parts are stocked with a 5-year minimum availability commitment.

Q9: How does the stretch blow process compare to injection blow molding for 4-cavity cosmetic production?

The stretch blow process stretches the preform biaxially — axially via stretch rod and radially via blow pressure — before completing the blow stage. This biaxial orientation aligns polymer chains in the container wall, producing higher drop resistance, better barrier properties, and superior optical clarity versus injection blow molding at equivalent output rates. For asymmetric and special-shaped cosmetic bottles, controlled in-line preform heating with zone-level control delivers more consistent wall distribution across complex profiles than rotary injection blow alternatives.

For wide-body lotion pumps, large cream jars, and daily chemical containers up to 94 mm body diameter and 1,000 ml — the 2-cavity HGA.AS-2C114.3 runs the 114.3 mm pitch format that the 4-cavity model cannot accommodate.
