EP-HGA.ES-2C260 Daily Chemical Plastic Bottle Blow Molder | Blow Molding Machine
The EP-HGA.ES-2C260 operates on the well-proven two step blow molding machine architecture, where preform injection and bottle blowing are fully separated into independent production steps. This structural approach is especially valuable at the large container scale this machine addresses — preforms for 2-liter to 5-liter containers carry substantially more mass than those used for cosmetic packaging, and the ability to condition them to precise temperature profiles in isolation from the blowing cycle results in far better material distribution control than any comparable single-stage approach. The 550 mm stretching stroke and 260 mm mold-close distance give the machine the mechanical reach to fully expand even the tallest and widest bottles in the daily chemical category. Understanding what the steps involved in the two-stage blow molding process contribute at this container scale helps buyers appreciate why this blow molding machine configuration sets the standard for large daily chemical bottle production.
Powered by international-brand servo motors and precision reducers, the EP-HGA.ES-2C260 blow molding machine maintains consistent mechanical performance throughout long production runs. The dual-cavity configuration produces two containers per cycle at a theoretical rate of 900 bottles per hour — a figure that reflects the extended cycle times inherent in blowing large-volume containers rather than any limitation of the machine design.

Why This Blow Molding Machine Stands Out for Large-Format Daily Chemical Production
5-Liter Capacity Ceiling
The EP-HGA.ES-2C260 blow molding machine reaches a maximum container volume of 5,000 ml, a range that places it clearly in the large-format daily chemical segment. Most competing blow molding machine models in the two-cavity class cap at 1,500 ml or 2,500 ml; this machine extends usable output to the 3-liter, 4-liter, and 5-liter container formats that bulk household product ranges and institutional cleaning supply companies require. That capability makes it one of the most dimensionally capable bottle blow molding machines available in this configuration class, particularly relevant for producers planning to serve both consumer retail and commercial supply channels from a single machine.
240 mm Diameter Tolerance
A maximum container diameter of 240 mm supports the broad, squat bottle formats common in bulk laundry, cooking oil, and professional cleaning product packaging — bottle geometries that require proportionally larger clamping systems, wider mold-close distances, and higher-capacity cooling circuits than narrow cosmetic containers. The 635 mm mold-open distance and 275 mm clamping stroke of this blow molding machine are matched to these dimensional demands, ensuring the machine can accept and cycle large-format tooling without mechanical strain or cycle interruption.
High-Flow Cooling Architecture
The cooling water flow rate of 91.4 ltr/min is substantially higher than smaller blow molding machine models in the same product family. This elevated flow capacity is a direct engineering response to the greater thermal mass of 5-liter PET preforms and the larger mold surface areas involved in blowing wide containers. Maintaining consistent mold temperature across this larger surface area is what separates dimensionally stable large-format bottles from containers with localized shrinkage, base distortion, or sidewall thinning — quality failures that are particularly costly when filling and labeling lines are tuned to precise bottle height and shoulder geometry.
Two-Stage Process Advantage at Scale
For large containers, the two-step blow molding machine architecture delivers benefits that become more pronounced as container volume increases. Preform temperature conditioning in the reheat oven is the primary variable controlling material distribution in the blown bottle — at 5-liter volumes, even small temperature non-uniformities in the preform translate to measurable wall-thickness variation in the finished container. The two-stage process allows the heating section to be tuned independently and precisely for each preform profile, a level of control that single-stage auto blowing machine designs cannot replicate at this container scale.
How to Choose the Right Blow Molding Machine for Large Daily Chemical Containers
Selecting a blow molding machine for large-format daily chemical containers requires a different evaluation framework than for cosmetic or pharmaceutical packaging. The first question is always maximum container volume: if the largest bottle you plan to produce is 2 liters or above, most standard two-cavity blow molding machine models cannot accommodate that tooling, and the EP-HGA.ES-2C260 becomes one of the few viable options at that size. Verify that the intended bottle diameter falls within the 240 mm ceiling and that the container height does not exceed 450 mm, as these boundaries define the usable tooling envelope on this blow molding machine.
The second filter is air supply infrastructure. The EP-HGA.ES-2C260 blow molding machine requires 6,000 ltr/min of high-pressure air at 35 kg/cm² — a demand that requires dedicated high-capacity compressor installation and appropriately sized distribution pipework. Producers who already operate large extrusion blow molding machine lines or injection blow molding machine systems will likely have compatible infrastructure; those setting up a new site need to size the air compressor correctly before the blow molding machine order is placed.
Third, consider cooling water capacity. The 91.4 ltr/min flow rate at 8 to 12 °C requires a suitably rated industrial chiller. Under-sizing the cooling system on a large-format blow molding machine is one of the most common commissioning problems in the daily chemical sector — insufficient cooling extends cycle time, degrades bottle dimensional stability, and reduces effective output per shift. Plan chiller capacity with margin above the specified flow rate so that the blow molding machine can run at full speed in warm ambient conditions without compromising bottle quality.
Finally, plan the plant floor layout around the machine footprint. At 5,570 mm in length, 2,030 mm in width, and 2,500 mm in height, this fully automatic blow moulding machine requires considerably more floor space than a standard cosmetic bottle machine. Allow adequate clearance on all sides for mold change access, preform loading, and bottle outfeed conveyor integration.
Mold Design
Preform Injection Mold
The die lip assembly consists of two precision-fitted sections that together maintain strict coaxial alignment throughout preform formation — a requirement that becomes even more critical for the heavy-wall preforms used in 3-liter to 5-liter container production. Internal cooling channels follow a carefully engineered path that extracts heat from preform walls at a controlled, uniform rate, shortening cycle time without compromising the dimensional stability that large bottle production demands. All cavity-forming surfaces are produced from imported 2316 die steel, selected for hardness and inherent corrosion resistance after heat treatment. Core plates, cavity plates, and structural components throughout are manufactured in 420 stainless steel, providing reliable protection against the corrosive environment created by cooling water contact. The tooling architecture keeps maintenance procedures accessible and straightforward, and a standardized fitting system supports interchangeability across the mold range, with individual toolsets capable of accommodating multiple preform specifications.
Blowing Mold
Large-format blowing molds on this blow molding machine are fabricated from premium steel chosen specifically for thermal conductivity and surface durability at the elevated mold scale required by wide-diameter containers. Each cavity profile is developed in advanced 3D CAD software prior to any machining, enabling full virtual validation of parting line geometry, cooling channel placement, and container wall-fill dynamics at the 240 mm diameter scale. A range of pre-engineered bottle profiles is available to reduce project lead time for standard daily chemical formats; fully custom cavity designs are accepted for brand-specific bottle shapes. Cooling passages are routed to achieve thermal uniformity across the entire cavity surface — a factor that has greater impact on base integrity and sidewall consistency in large containers than in small ones. All mold metalwork is finished on CNC machining centers to maintain the dimensional precision required for repeatable, cycle-to-cycle bottle quality.
Scenari applicativi

Laboratorio
Related Auxiliary Equipment
A complete blow molding machine installation at this container scale requires carefully matched auxiliary systems. We supply or specify each of the following to remove the guesswork from utility interface planning and support single-source project delivery.
Air Compressor
Oil-free high-pressure compressors rated for sustained 35 kg/cm² delivery at 6,000 ltr/min high-pressure air consumption. At this blow molding machine scale, compressor specification is a critical commissioning variable — undersizing the air supply is the most common cause of below-rated output on large-format machines.
Regolatore di temperatura dello stampo
Water-type mold temperature controllers maintaining the 8 to 12 °C blow molding machine circuit temperature. Consistent mold temperature is especially important at 5-liter container scale, where any thermal gradient across the cavity surface translates directly into base-geometry or sidewall-consistency defects in the finished bottle.
Bottle Visual Inspection Machine
Downstream vision inspection systems positioned after the auto blowing machine discharge to detect wall defects, contamination, and dimensional non-conformances in large-format containers before they reach the filling line — particularly valuable where 5-liter bottle rejects represent significant material waste per incident.
Industrial Chiller
High-flow industrial chillers delivering 91.4 ltr/min at 8 to 12 °C to the blow molding machine cooling water circuit. At this flow rate, chiller sizing and piping design must be engineered for the specific installation — a standard packaged chiller sized for smaller machines will not support this blow molding machine at full rated output.
Domande frequenti
What makes a two-stage blow molding machine the better choice over a single-stage machine when producing large 3-liter to 5-liter daily chemical containers for wholesale markets in Colombia?
At container volumes of 3 liters and above, the two-stage blow molding machine process provides far better control over preform temperature conditioning than any single-stage approach. Preforms for large daily chemical containers have significantly greater wall mass, and achieving uniform temperature distribution across that mass requires a dedicated reheat section that runs independently from the blowing cycle. This allows the heating parameters to be tuned precisely for each preform weight and geometry, resulting in more uniform wall thickness distribution in the blown container — a quality outcome that directly reduces material cost per bottle and improves filling-line performance by delivering more consistent bottle height and shoulder geometry.
Which auxiliary systems does a large-format pet blow molding machine installation require, and how should daily chemical manufacturers in Latin America plan for them?
A large-format pet blow molding machine like the EP-HGA.ES-2C260 requires three critical auxiliary systems: a high-capacity oil-free air compressor rated for sustained 35 kg/cm² output at 6,000 ltr/min, an industrial chiller providing 91.4 ltr/min of cooling water at 8 to 12 °C, and a mold temperature controller to maintain blowing mold temperature stability. Each of these must be specifically sized for the EP-HGA.ES-2C260 operating parameters rather than reused from a smaller machine installation. For Latin American manufacturers planning a new line, the compressor and chiller infrastructure should be specified and ordered at the same time as the blow molding machine to avoid commissioning delays.
How does a fully automatic blow moulding machine handle wide-neck container formats up to 168 mm that are common in bulk household cleaning product packaging?
A fully automatic blow moulding machine like the EP-HGA.ES-2C260 handles wide-neck containers through a combination of a larger preform holder system, an extended mold-close distance of 260 mm, and a clamping stroke of 275 mm that can accommodate the wider mold body required by a 168 mm neck finish. The neck finish is formed during the preform injection stage and carried through the reheat and blowing phases without dimensional change — only the bottle body expands during blowing. Wide-neck containers are common in institutional cleaning supply packaging where fast pouring and wide-mouth filling compatibility with gravity-fill or volumetric fill equipment are required.
Where should a blow molding machine manufacturer look when evaluating whether a two-step blow molding machine is the right fit for a new large-format cooking oil or edible oil packaging line?
The evaluation should start with container volume — if the target bottle is 2 liters or above, the two-step blow molding machine route is generally preferred because it gives better control over material distribution in heavy-wall preforms. Next, check regulatory compliance requirements for food-contact PET — the machine must be capable of processing food-grade resin without contamination risk, and documentation of material traceability may be required by retailers or export market authorities. Then evaluate throughput against the annual volume forecast and factor in the larger floor area and utility supply requirements that large-format blow molding machine installations demand compared with cosmetic or pharmaceutical packaging lines.
What are the differences between single-stage and two-stage blow molding for PET bottles when the container size exceeds 2 liters in the daily chemical or food packaging industry?
For PET bottles above 2 liters, the differences between single-stage and two-stage blow molding become more operationally significant than at smaller container sizes. In the single-stage process, the preform is blown immediately after injection before it fully cools, which constrains how precisely the resin temperature can be controlled across a heavy-wall preform before blowing. In the two-stage process, preforms are cooled completely, stored, and then selectively reheated in a controlled reheat oven before blowing — giving operators a precise, repeatable temperature profile across the entire preform mass regardless of wall thickness.
