EP-HGA.ES-4C100 Daily Chemical Plastic Bottle Blow Molder | Blow Molding Machine
The EP-HGA.ES-4C100 operates on the two-stage blow molding machine platform common to the entire ES product family, but takes the cavity count to four — a configuration that fundamentally changes the economics of high-volume daily chemical bottle production. In the two step blow molding machine process, preforms are produced and stored separately, then reheated and blown in the four-cavity section simultaneously. With 92 preform holder positions supporting the elevated preform throughput the four blowing cavities demand, and international-brand servo motors driving all primary mechanical movements, this blow molding machine is designed to sustain its 4,600 bph rated output across multi-shift production schedules without compromising bottle dimensional consistency or wall thickness uniformity.
The container range — up to 800 ml, 80 mm body diameter, 250 mm height — is deliberately concentrated on the core daily chemical bottle formats where volume is highest and production efficiency is most directly linked to profitability. What makes this pet blow molding machine particularly well suited to that segment is the combination of four-cavity throughput and the two-stage process quality advantage: the reheat section conditions all 92 preforms at once to a precisely uniform temperature before they reach the blowing cavities, giving each of the four cavities the same material starting point. This consistency across cavities is what keeps bottle weight variation within the tight tolerances that automated filling, capping, and labeling lines require.
EP-HGA.ES-4C100 Daily Chemical Plastic Bottle Blow Molder
The EP-HGA.ES-4C100 is a four-cavity, fully automatic blow moulding machine engineered for the most output-intensive daily chemical packaging operations. Running four blowing cavities simultaneously, this blow molding machine reaches a theoretical rate of 4,600 bottles per hour — the highest throughput figure in this product family for containers in its size class. Targeting PET and PETG containers up to 800 ml with a body diameter of 80 mm and a maximum height of 250 mm, it is purpose-built for the high-volume standard daily chemical formats: shampoo, conditioner, hand soap, body wash, and personal care bottles that move through retail supply chains in tens of millions of units each year. For producers in Colombia and global markets who need maximum per-machine output without proportionally scaling their footprint, the EP-HGA.ES-4C100 blow molding machine is the logical endpoint of the ES-series product family.

Why High-Volume Producers Choose This Four-Cavity Blow Molding Machine
4,600 bph Peak Output
Running all four blowing cavities simultaneously, the EP-HGA.ES-4C100 blow molding machine delivers 4,600 bottles per hour — roughly double the output of a two-cavity blow molding machine of equivalent container size. For daily chemical producers in Colombia and major export markets targeting annual volumes of 25 million to 30 million bottles per year on a single format, this four-cavity blow molding machine eliminates the need to run parallel machines for the same SKU. That consolidation reduces total machine count, simplifies maintenance scheduling, and lowers the operator-to-output ratio across the production cell.
Compact Footprint for Output Level
At 4,170 mm x 1,930 mm x 2,340 mm and 4,000 kg, this four-cavity blow molding machine occupies a footprint that is competitive with many two-cavity blow molding machine models while delivering more than twice the hourly output. For plants where floor space is a constraint — a common situation in established daily chemical packaging facilities in Latin America that are expanding output rather than building new — the EP-HGA.ES-4C100 offers the most favorable bottles-per-square-meter ratio in the ES-series lineup, making it a practically significant advantage in capacity expansion planning.
Servo Efficiency at Scale
Despite a 62.5 kW maximum installed power, normal operating power holds at 21 kW — a servo-driven efficiency profile that reflects load-proportional torque delivery rather than constant power draw. At 4,600 bph output, the per-bottle energy consumption of this blow molding machine compares favorably against both older hydraulic blow molding machine designs and against running two separate two-cavity machines to achieve the same total output. Over a multi-shift production year, the accumulated energy saving across the four-cavity blow molding machine installation translates into a measurable operating cost advantage per million bottles produced.
Consistent Four-Cavity Quality
Maintaining consistent bottle weight and wall thickness across four blowing cavities simultaneously is the central quality challenge of any four-cavity blow molding machine. The two-stage process used by the EP-HGA.ES-4C100 addresses this directly — preforms are conditioned in the 92-position reheat chain to a uniform temperature profile before reaching the blowing section, giving all four cavities identical material input conditions. This upstream temperature consistency is what keeps cavity-to-cavity bottle weight variation within the tight limits that downstream filling, capping, and quality inspection systems operate on.
How to Choose the Right Blow Molding Machine for Your Production Volume
The EP-HGA.ES-4C100 is the right blow molding machine choice when two conditions align: the container being produced fits within 800 ml volume, 80 mm body diameter, and 250 mm height; and the annual production requirement for that container format exceeds what a three-cavity blow molding machine can deliver at planned shift patterns. At roughly 75% OEE, the EP-HGA.ES-4C100 blow molding machine delivers approximately 3,450 effective bottles per hour. At three shifts over 300 working days, that represents approximately 24 to 25 million bottles per year on a single format — a volume that justifies the four-cavity investment for any major daily chemical brand or contract packaging operation serving national retail accounts.
Air supply is the most important utility to evaluate before ordering this blow molding machine. High-pressure air consumption of 4,000 ltr/min at 35 kg/cm² is a significant demand that requires a dedicated high-capacity oil-free air compressor. Sites that already operate three-cavity blow molding machine lines should verify whether their existing compressor has headroom for the four-cavity air demand, or budget for a compressor upgrade. The low-pressure air consumption of 800 ltr/min at 7 kg/cm² is more manageable and can often be supplied from existing plant compressed air rings with appropriate pressure regulation.
Cooling water at 30 ltr/min and 8 to 12 °C is within the range of standard mid-size industrial chillers. Unlike the large-format EP-HGA.ES-2C260 blow molding machine, the cooling water flow rate on this four-cavity model does not require oversized chiller infrastructure, despite the higher bottle throughput — a reflection of the smaller container thermal mass involved. Finally, assess the floor layout: the machine dimensions of 4,170 mm x 1,930 mm x 2,340 mm require adequate clearance for mold change access and outfeed conveyor integration, with enough space for a bottle visual inspection machine positioned immediately downstream.
Mold Design
Preform Injection Mold
The die lip assembly is built from two precision-matched sections that together enforce strict coaxial alignment during preform formation — a requirement that becomes proportionally more significant as cavity count increases, because any preform eccentricity at the injection stage shows up as cavity-to-cavity wall thickness variation in the blown bottle. Internal cooling channels are optimized to extract heat from the preform wall at a controlled, repeatable rate, supporting the fast cycle times the 4,600 bph four-cavity blowing section demands. Cavity-forming components are machined from imported 2316 die steel after heat treatment, combining surface hardness with the inherent corrosion resistance that extended cooling water contact requires. Core plates, cavity plates, and structural components are manufactured from 420 stainless steel throughout. The toolset is designed for efficient field servicing, supported by a standardized fitting system that allows interchangeability across the mold program and enables a single toolset to run multiple preform specifications where production scheduling requires it.
Blowing Mold
Four-cavity blowing molds on this blow molding machine are fabricated from high-grade steel with the thermal conductivity and surface durability needed to maintain consistent bottle quality across four simultaneous blowing positions. Every bottle cavity is modeled in advanced 3D CAD software before machining begins, validating parting geometry, cooling channel placement, and wall fill dynamics across all four positions simultaneously. A wide selection of pre-engineered daily chemical bottle profiles is available for standard format launches; custom cavity designs are accepted for brand-specific packaging programs. Cooling passages are routed to achieve even thermal drawdown across all four cavity surfaces within each blowing cycle — the uniformity that prevents position-to-position bottle weight variation at 4,600 bph output rates. All mold metalwork is finished on CNC machining centers to dimensional tolerances that support repeatable production across the working life of the tooling.

Related Auxiliary Equipment
A four-cavity blow molding machine installation demands precisely matched auxiliary systems. We specify or supply each of the following to ensure the EP-HGA.ES-4C100 reaches its rated output from first production shift.
Air Compressor
Oil-free high-pressure air compressors rated for sustained 35 kg/cm² at 4,000 ltr/min. The four-cavity blow molding machine is the highest air consumer in the ES product family — compressor specification is a project-critical decision that must be made before site preparation begins.
Kontroler temperatury formy
Water-type mold temperature controllers holding the blow molding machine cooling circuit between 8 and 12 °C. Thermal uniformity across all four blowing cavities simultaneously is the single most important variable in maintaining bottle weight consistency at 4,600 bph output.
Bottle Visual Inspection Machine
At 4,600 bph, inline bottle visual inspection becomes essential rather than optional. Inspection systems positioned immediately after this auto blowing machine detect wall defects, contamination, and dimensional deviations at line speed, keeping the filling station protected from non-conforming containers at full throughput rates.
Industrial Chiller
Industrial chillers providing 30 ltr/min at 8 to 12 °C to the blow molding machine cooling circuit. While the flow rate requirement is moderate for the machine output level, cooling water temperature stability across all four cavity positions throughout multi-shift production directly determines cavity-to-cavity bottle weight repeatability.
Często zadawane pytania
What makes a four-cavity blow molding machine the better investment over running two separate two-cavity machines for high-volume shampoo bottle production in Colombia?
A single four-cavity blow molding machine like the EP-HGA.ES-4C100 delivers comparable total output to two two-cavity machines while requiring only one machine footprint, one set of utility connections, one maintenance schedule, and typically one operator. The capital cost of a single four-cavity blow molding machine is substantially lower than two separate two-cavity machines of equivalent total throughput. Additionally, running a single blow molding machine simplifies production scheduling, reduces the tooling investment needed to run the same bottle format across multiple machines, and makes it easier to maintain consistent bottle quality across all output — since all bottles come from a single controlled process rather than two parallel machines that may have subtle setup differences between them.
How does a fully automatic blow moulding machine with four cavities maintain consistent bottle quality across all four positions during extended production runs?
Consistency across four cavities on a fully automatic blow moulding machine like the EP-HGA.ES-4C100 depends primarily on two variables: preform temperature uniformity entering the blowing section, and mold cooling uniformity across all four cavity positions. The 92-position reheat chain conditions all preforms to the same temperature profile before they reach the blowing cavities, eliminating the preform-to-preform temperature variation that would otherwise produce cavity-to-cavity bottle weight differences. On the blowing side, the mold cooling circuit is engineered to maintain thermal uniformity across all four cavities simultaneously — meaning each position draws heat from the blown container at the same rate and reaches the same ejection temperature within each cycle. These two controls together are what keeps bottle weight variation within the tolerances that automated downstream filling and inspection systems operate on.
Which daily chemical bottle formats are the best match for a four-cavity automatic pet blowing machine producing 800 ml containers in the Latin American market?
The EP-HGA.ES-4C100 blow molding machine is optimized for the standard personal care and household product bottle formats that represent the highest unit volumes in the daily chemical market. Shampoo bottles in the 200 ml to 500 ml range, conditioner bottles up to 800 ml, hand soap containers, and body wash bottles are the most common formats produced on four-cavity machines in the Latin American daily chemical sector. These formats are characterized by standard oval or round cross-sections, moderate neck finish diameters within the 66 mm ceiling, and consistent wall geometry that allows the four blowing cavities to run identical tooling and produce interchangeable bottles without cavity-specific adjustment.
What air compressor capacity does a four-cavity pet blow molding machine require, and how should packaging manufacturers in Colombia plan for this infrastructure?
The EP-HGA.ES-4C100 pet blow molding machine requires 4,000 ltr/min of high-pressure air at 35 kg/cm² on a sustained basis throughout the production cycle. This is the highest high-pressure air demand of any model in the ES-series product family and requires a dedicated oil-free air compressor rated for this output — not a shared plant compressed air ring. For Colombian manufacturing facilities planning a new installation, the compressor should be specified at the same time as the blow molding machine order so that the compressor installation, pipework, and pressure regulation are ready before the blow molding machine arrives on site. Installing the machine with an undersized air supply is the most common source of below-rated output and premature valve wear on four-cavity blow molding machine installations.
How does the two-stage blow molding process on the EP-HGA.ES-4C100 improve PET bottle wall thickness consistency compared with single-stage machines at similar output rates?
In the two-stage blow molding process used by the EP-HGA.ES-4C100, preforms are fully cooled after injection, stored, and then reheated to a precisely controlled and uniform temperature profile before blowing. This reheating step is what gives the two-stage process its quality advantage over single-stage alternatives at high output rates — the reheat oven conditions each preform to the same temperature across its entire wall thickness before it enters the blowing cavity, regardless of how the preform cooled during storage.
