EP-HGA.P.FS-2CB130 2 Cavities Baby Bottle & PP Bottle Blow Molding Machine

1,000 bph Dual-Cavity Output

The 2-cavity configuration delivers 1,000 bph under standard production conditions — output that typically requires two separate single-cavity blow molding machines with double the operator requirement. For factories in Colombia or Brazil scaling from pilot production to retail supply volumes, this efficiency gain shortens the time to positive cash flow on the machine investment. Both cavities receive air simultaneously through a balanced distribution manifold, maintaining consistent expansion timing across both bottles in every cycle.

Two-Step Preform Conditioning Retained

The move to 2 cavities does not compromise the preform conditioning quality that makes the two-step process the preferred method for baby bottle and pharmaceutical packaging. The 74-position heating carousel provides each preform with the same controlled dwell time through independently regulated infrared zones, regardless of whether 1 or 2 cavities are active. This conditioning consistency is what allows the machine to meet the dimensional tolerances that baby bottle safety certification requires — tolerances that single-stage machines struggle to hold at equivalent output rates.

Balanced Air Distribution for Uniform Bottle Quality

Running 2 cavities simultaneously introduces air distribution as a critical process variable. The HGA.P.FS-2CB130 uses a precision-engineered pneumatic manifold that supplies identical pressure to each cavity throughout the blowing and pre-blowing phases. This symmetry is verified during factory acceptance testing using weight and capacity checks on both cavity outputs. The result is two bottles per cycle with matched wall thickness profiles — the starting point for predictable downstream filling and capping performance on high-speed packing lines.

High Heating Capacity for Sustained Output

At 66 kW maximum heating power — more than five times the HGA.FS-1CG150 — the HGA.P.FS-2CB130 sustains the heating throughput needed to condition two preform streams simultaneously at 1,000 bph. The additional 38 kW supplementary heating block provides reserve capacity that compensates for preform batch variations in resin crystallinity, which affect how quickly each preform reaches optimal blowing temperature. This reserve capacity prevents the thermal bottleneck that causes output rate reduction in high-heating-demand operating conditions.

Compact Footprint for a 2-Cavity Machine

The HGA.P.FS-2CB130 occupies a 4,510 × 1,800 × 2,050 mm floor envelope at 4,000 kg — large by single-cavity standards but compact relative to the output it delivers. Most factories already accommodating a single-cavity machine in this series can house this model without floor-plan reconfiguration. For industrial estates in Colombia or Southeast Asia where bay dimensions are standardized and expansion involves new lease costs, keeping the machine footprint within existing infrastructure constraints is a real operational benefit.

Preform Injection Mold

• The split die-lip construction keeps the preform gate area concentric with the body axis throughout the full formation sequence, preventing the eccentric wall sections that cause asymmetric blowing behavior in paired-cavity production.
• Internal cooling gallery routing is optimized for maximum preform surface coverage, reducing cycle time while controlling post-injection shrinkage variation between the paired preforms.
• All forming surfaces are machined from imported die steel 2316 — heat-treated and rust-resistant, suitable for continuous operation in the humid environments typical of tropical production facilities.
• Core and cavity structural components use 420 stainless steel for corrosion resistance, selected for long-term performance without plating or surface treatment maintenance.
• The modular insert architecture allows worn forming components to be replaced without removing the full mold from the machine, reducing scheduled maintenance downtime.
• Standard-dimension interchangeable fittings mean a single mold design can accommodate multiple preform geometries, reducing tooling investment for factories running more than one bottle SKU.

Blowing Mold

• The 2-cavity blowing mold is fabricated from certified quality tool steel selected for impact resistance and thermal stability across continuous multi-shift blow cycles.
• Cavity geometry for both bottle positions is generated using 3D parametric modeling software, ensuring the two cavities are dimensionally identical at the tooling level — the foundation of balanced output between paired cavities.
• A broad library of bottle shapes is available, including round, oval, ergonomic-grip, and compact baby bottle profiles suited to the 110 mm maximum container diameter of this machine.
• Cooling channels in both cavity halves are flow-simulated for balanced thermal extraction, preventing the differential shrinkage between the two cavities that leads to height and capacity variation in the finished bottles.
• All metal components across both cavity positions are finish-machined on CNC equipment to matched tolerances, ensuring the two cavities produce interchangeable bottles without requiring separate qualification of each cavity output.

Baby Bottle Production at Scale

Standard baby bottle sizes — 150 ml, 250 ml, 330 ml — are produced two per cycle on the HGA.P.FS-2CB130, with the neck-finish precision and wall uniformity that baby product safety certification requires. At 1,000 bph, a single shift produces approximately 8,000 bottles — enough for meaningful retail supply without the overhead of a large-format multi-cavity installation. The machine is well matched to the mid-tier baby bottle brands growing in Colombia, Mexico, and Southeast Asia.

PP Beverage & Water Bottles

PP water bottles in the 500 ml to 1,500 ml range for sports, outdoor, and institutional markets are a good match for the HGA.P.FS-2CB130's container specification. PP's odor neutrality and resistance to repeated washcycles makes it the preferred material over PET for reusable bottle brands. The auto blowing machine handles both transparent and pigmented PP grades, giving brand owners the material flexibility to serve different market segments from one production cell.

Pharmaceutical Liquid Containers

Dual-cavity production of oral liquid pharmaceutical bottles — syrups, drops, suspensions — in the 100 ml to 500 ml range gives contract pharmaceutical packagers the throughput to supply retail pharmacy chains and hospital procurement programs. PP's compatibility with autoclave sterilization and broad pharmaceutical excipient resistance makes it the material of choice for this application. The machine's fully automated cycle removes operator contact from bottle interiors throughout production.

Personal Care & Cosmetics Bottles

Shampoo, conditioner, and body wash bottles in the 300 ml to 1,000 ml range, along with compact cosmetic containers in transparent PETG for shelf-appeal, are well within the container specification envelope of this plastic blowing machine. The 2-cavity output rate is well-matched to mid-volume cosmetics brands building their own production capacity rather than relying entirely on third-party contract filling operations.

Food & Condiment Packaging

Condiment bottles for soy sauce, vinegar, and specialty food sauces in the 500 ml to 1,500 ml range fit the HGA.P.FS-2CB130's container volume range with the 110 mm maximum diameter covering most standard retail condiment profiles. The bottle blow molding machine's ability to run PP — which is FDA food-contact compliant and grease-resistant — makes it practical for edible oil and sauce brands in Colombia and neighboring markets that are expanding domestic bottling capacity.

Output Requirement: 700–1,200 bph

If your current single-cavity machine is running at full capacity and you need more output without buying a second machine, the 1,000 bph rated output of this model fits the gap between single-cavity and high-count multi-cavity systems. Confirm that your downstream filling and packaging line can accept the increased bottle flow before specifying the machine's output as a constraint.

Container Diameter Below 110 mm

The 110 mm maximum container diameter of the HGA.P.FS-2CB130 covers standard baby bottles, pharmaceutical liquid containers, personal care bottles, and most retail beverage formats in the sub-1.5-litre range. If your product requires a container wider than 110 mm, the HGA.FS-1CG220 or a larger 2-cavity model in the ES series is the correct specification.

Utility Capacity Verification

The 2-cavity machine draws 66 kW maximum heating power, uses 1,500 ltr/min low-pressure air, and requires 1,000 ltr/min at 30 kg/cm² for blowing. Before committing to purchase, verify that your facility's electrical supply, compressed air system, and cooling water infrastructure can sustain these demands. In Colombia and tropical markets, cooling water temperature must be maintained at 8–10°C — a chiller is typically required rather than optional.

Quality Requirements for Dual-Cavity Output

Two-cavity production introduces the requirement to validate and monitor both cavity outputs separately, particularly for pharmaceutical and baby bottle products with tight dimensional specifications. Integrating a downstream visual inspection system that can distinguish and log results by cavity position is best practice for regulated applications. Factor this auxiliary equipment into your line design from the beginning rather than as a later addition.

Oil-Free Air Compressor

Supplying 1,000 ltr/min at 30 kg/cm² to two cavities simultaneously requires a compressor sized with a 20–25% buffer above rated consumption. Oil-free compressor types — screw or high-pressure piston — are mandatory for baby bottle and pharmaceutical container production, where oil contamination inside bottles triggers immediate product rejection. Verify compressor output at local ambient temperature before specifying, especially for tropical installations in Colombia or Southeast Asia where ambient conditions reduce rated output.

مولڈ ٹمپریچر کنٹرولر

The 2-cavity blowing mold has greater total cooling surface than a single-cavity design, making precise water temperature control more important — not less. A dedicated mold temperature controller circulates water at the 8–10°C set point required by this machine, stabilizing mold surface temperature across shift transitions and compensating for ambient variation. Consistent mold temperature is the single factor most responsible for maintaining matched bottle dimensions between the two cavities over extended production runs.

Bottle Visual Inspection Machine

With two cavities producing bottles simultaneously, a camera-based inline inspection system needs to track and evaluate both cavity outputs independently. This allows quality control to distinguish whether a developing defect is cavity-specific — indicating a mold or air distribution issue — or uniform across both cavities, indicating a preform or heating problem. For baby bottle and pharmaceutical packaging operations, 100% automated inspection before the filling line is increasingly a customer-mandated quality requirement rather than a best-practice recommendation.

Industrial Chiller & Utility Package

In tropical markets — Colombia, Indonesia, Ghana — facility cooling water routinely arrives at temperatures between 28°C and 35°C, far above the 8–10°C specification for this machine. An industrial chiller is not optional in these environments; it is the difference between a line that runs within specification and one that produces progressively distorted bottles as mold temperature rises through a shift. We offer matched chiller and compressor packages sized for this machine's consumption profile, simplifying site utility planning for new installations.
