EP-HGA.ES-6C76 Daily Chemical Bottle Blow Molder
Model: EP-HGA.ES-6C76 | Series: Daily Chemicals & Cosmetic Bottle Blow Molding Machine
The EP-HGA.ES-6C76 is a six-cavity high-output blow molding machine built for daily chemical and cosmetic bottle manufacturing operations where throughput is the primary constraint. Rated at 7,200 bottles per hour, it nearly doubles the production rate of four-cavity models in the same series — an important distinction for contract packaging facilities and brand owners that run large-volume SKUs of lotion, shower gel, and body-care containers in the 50 ml to 700 ml range. The machine operates on a proven two-step blow molding machine principle: preforms are sourced or produced separately and then conditioned through a zoned infrared heating system before being stretch-blown in the six-cavity blowing station. Internationally recognized servo motors, precision reducers, and a PLC-based control platform underpin the drive architecture, delivering the positional accuracy and energy efficiency that modern cosmetic packaging lines expect. For manufacturers in Colombia, broader Latin America, and global markets looking for a fully automatic blow moulding machine optimized for smaller, high-run cosmetic formats, the 6C76 represents a focused engineering solution.

Six-Cavity Performance — What Sets This Blow Molding Machine Apart
Moving from four to six cavities changes the economics of high-volume daily chemical bottle production significantly. At 7,200 bph, this plastic blow molding machine can supply a downstream filling line running at full capacity without buffer inventory concerns — a logistical advantage that four-cavity systems often cannot match on the same shift schedule.
With a maximum container volume of 700 ml and a body diameter ceiling of 68 mm, this auto pet blowing machine is purpose-designed for the compact cosmetic formats — travel-size shampoo, perfume accessory bottles, hand-cream containers, and single-dose personal care packaging — where per-unit margin depends on production efficiency.
A 38 mm maximum neck diameter is the defining dimensional characteristic of this bottle blow molding machine. It targets standard cosmetic closure formats — PP and aluminum screw caps, disc-top and flip-top closures — that dominate the 100 ml to 500 ml personal care segment globally.
At 4690×2000×2000 mm, this six-cavity automatic pet blowing machine occupies a notably shorter floor footprint than larger-volume models in the range. Facilities with constrained bay lengths can install the 6C76 alongside existing filling or labeling equipment without major layout reorganization.
High-Output Production with a Six-Cavity Two-Stage Blow Molding Machine
The defining characteristic of the EP-HGA.ES-6C76 within the daily chemical bottle series is its six-cavity layout, which pushes theoretical output to 7,200 bottles per hour. To understand why this matters operationally, it helps to compare the two-stage blow molding machine model it uses against single-stage alternatives. In a two-stage system, preform injection and bottle blowing are handled in separate steps, meaning the blowing station — in this case six cavities running simultaneously — can be dedicated entirely to the blow cycle without waiting on an injection phase. This architecture is the reason two-stage platforms consistently deliver higher output per unit of floor space than comparable single-stage machines.
The 6C76 processes preforms through a 130-position mandrel holder system, feeding them through an independently zoned infrared heating tunnel. Each infrared lamp zone operates at a programmable power level, enabling engineers to set a precise temperature gradient along the preform body — a capability that is particularly valuable when processing thin-wall preforms intended for 38 mm neck diameter closures, where the conditioning window is narrower than for larger formats. After the heating stage, the blow station activates six stretch rods simultaneously, each extending to a 350 mm stroke while high-pressure air at 35 kg/cm² inflates the preform cavities. The result is biaxially oriented PET or PETG bottles with the optical clarity and structural integrity that cosmetic and personal care brands require. For facilities in Colombia and across global export markets, this auto blowing machine offers a reliable path to the throughput levels that make small-format bottle production economically viable.
Mold Engineering
Preform Injection Mold
The die lip on this preform mold is a two-segment assembly that holds the preform on a shared axis throughout the injection event — a geometric prerequisite for achieving consistent wall concentricity across all six cavities. Cooling passages are routed to maximize heat extraction rate from the preform body, cutting conditioning cycle time without causing surface crystallinity. Forming elements are machined from 2316 imported die steel, chosen for its resistance to moisture-driven corrosion and its dimensional stability after heat treatment. Load-bearing plates, core holders, and cavity frames use 420 stainless steel for long-term corrosion resistance across extended production campaigns. The interchangeable fitting system simplifies scheduled maintenance and allows a single mold body to accommodate more than one preform geometry — reducing tooling redundancy for operations running multiple 38 mm neck SKUs.
Blowing Mold
Six-cavity blow mold bodies for the ES-6C76 are manufactured from premium-grade tool steel graded for both hardness and thermal conductivity — both properties influence how efficiently heat exits the freshly blown bottle during the cooling hold phase. Bottle cavity profiles are generated using three-dimensional CAD software, which allows slender 68 mm diameter cosmetic containers with complex shoulder curves, faceted surfaces, and fine label-panel geometry to be captured precisely before a single millimeter of steel is cut. Cooling channels are designed into the mold body as an integral feature rather than a secondary modification, ensuring temperature uniformity across all six cavities. All machined surfaces are finished on CNC equipment to consistent dimensional tolerances, producing low-flash parting lines across high-run production.
Key Structural Advantages
At 7,200 bph, this pet blow molding machine delivers roughly twice the per-hour output of four-cavity models in the same daily chemical series — a direct labor and per-unit cost advantage for high-volume production runs.
The 76 mm preform mold-close distance is optimized for the compact preforms used in 38 mm neck containers. Shorter preforms cycle through the heating tunnel faster, supporting the high bph rating without sacrificing temperature uniformity.
Servo-controlled clamping and stretching motions are applied uniformly across all six positions. This eliminates the cavity-to-cavity variation in wall thickness and bottle height that hydraulic systems often introduce under repeated high-cycle loading.
The 4690 mm machine length is noticeably shorter than higher-volume models in the series, despite the six-cavity blowing station. This footprint efficiency benefits facilities where floor space is shared with filling, capping, and labeling equipment.
The independently zoned heating system adapts to the conditioning profiles of multiple resin types. Switching between PET and PETG, or from standard to impact-modified grades, requires adjustment of heating zone setpoints rather than hardware changes.
Like other models in the series, the 6C76 is designed for high-difficulty asymmetric cosmetic containers. The precision servo stretch rod system handles non-round cross-section preforms and irregular shoulder profiles that other automatic pet blowing machine platforms avoid.

How to Select the Right Blow Molding Machine for Small-Format Cosmetic Bottle Production
When evaluating what are the different types of blow molding machines for small-format container production, the six-cavity configuration stands out as the right architecture for operations where bottles fall within the 700 ml ceiling and neck diameter stays below 38 mm. The EP-HGA.ES-6C76 belongs in the shortlist when all of the following conditions apply: your primary container formats are between 50 ml and 700 ml; your closure specification uses a standard 38 mm neck finish; your hourly demand from filling lines is in the 5,000–7,200 bph range; and your facility has the compressed air infrastructure to support 5,800 ltr/min high-pressure flow at 35 kg/cm².
Related Auxiliary Equipment
A blow molding machine running at 7,200 bph requires a supporting utility ecosystem that is matched to its operating demands. We supply the following auxiliary systems as part of a validated one-stop packaging line solution.
Air Compressor
Supplying 5,800 ltr/min of clean high-pressure air at 35 kg/cm² is the critical utility requirement for this blow molding machine. An oil-free compressor is mandatory for cosmetic and pharmaceutical container production, where any oil carry-over into the bottle interior creates quality and regulatory problems. Our oil-free compressor range is sized and validated against the 6C76 air consumption figures to eliminate under-supply events that interrupt the blow cycle.
Contrôleur de température du moule
Maintaining blow mold cavity temperature at 8–12 °C across six simultaneous cavities during a 7,200 bph production run requires active thermal management. Our mold temperature controllers integrate directly with the mold's water circuit, preventing the gradual heat accumulation that lengthens cycle time and softens bottle bases as a run extends across multiple shifts. Units are selected and validated against the 6C76's 40 ltr/min cooling water flow specification.
Bottle Visual Inspection Machine
Seven thousand bottles per hour cannot be manually inspected at acceptable accuracy levels. A vision-based bottle visual inspection machine installed on the conveyor after the blow station uses multi-camera scanning to identify surface scratches, gate marks, dimensional deviations, and foreign-matter contamination before bottles reach the filling station. This addition is particularly valuable in pharmaceutical and premium cosmetic lines where batch recall risk is high.
Chiller & Cooling Water System
Reliable chilled water supply at 5–6 kg/cm² and 8–12 °C underpins cycle stability across an extended production run. Industrial chillers from our auxiliary range are sized to the 6C76 blow molding machine's 40 ltr/min cooling specification and rated to maintain setpoint temperature even during peak summer ambient conditions — a factor that matters for facilities in tropical climates including Colombia and Southeast Asia.

Foire aux questions
Q1. How does a six-cavity two-stage blow molding machine improve per-unit production economics for small-format cosmetic bottle manufacturers in Colombia?
Moving from four to six cavities on a two-stage blow molding machine increases bottles-per-hour output without requiring a proportional increase in floor space, operators, or machine cycle time. For a facility in Colombia producing standard 200 ml to 500 ml cosmetic bottles, the jump from roughly 3,300 bph to 7,200 bph means the same shift hours produce more than twice as many finished bottles. This directly reduces the per-unit machine depreciation cost and can eliminate the need for a second machine on the same product family — a significant capital saving for mid-sized contract packaging operations serving Colombia, Ecuador, and the wider Andean market.
Q2. What bottle formats and closure specifications work best with a fully automatic blow moulding machine that has a 38 mm maximum neck diameter?
A 38 mm neck diameter ceiling aligns with standard 38-400, 38-410, and 38-415 closure specifications — the thread families used on the majority of shampoo, lotion, hand-wash, and conditioner bottles in the 100 ml to 700 ml range globally. Disc-top closures, flip-top caps, lotion pumps with 38 mm collars, and aluminum screw caps in the same size range are all compatible formats. This makes the EP-HGA.ES-6C76 directly relevant to any daily chemical brand running standard closure tooling on their filling line, since no closure-tooling investment change is needed when switching to bottles produced on this blow molding machine.
Q3. Which technical differences between a stretch blow molding machine and an extrusion blow molding machine matter most when choosing equipment for PET hand-sanitizer bottles?
For PET hand-sanitizer bottles, a stretch blow molding machine like the EP-HGA.ES-6C76 is the preferred choice for three technical reasons. First, biaxial molecular orientation during the stretch-blow event produces bottles with significantly better wall-strength-to-weight ratios than extrusion blow molding produces with the same resin. Second, PET processed through a stretch blow molding machine achieves optical clarity that makes product color and fill level immediately visible — a hygiene-signal that consumers associate with quality. Third, the dimensional accuracy of stretch-blown necks is tighter than extrusion-blown alternatives, which reduces closure-fit variation on high-speed capping lines. Extrusion blow molding is the correct choice for HDPE or PP containers, or for designs with handles, but it is not competitive with PET stretch blow for transparent personal care formats.
Q4. When is the right time for a personal care bottle manufacturer to upgrade from a four-cavity to a six-cavity automatic pet blowing machine?
The decision to move from four to six cavities is typically triggered by one or more of the following: a filling line that is currently running slower than its rated speed because the blow molding machine cannot feed it fast enough; a production schedule that requires more than two production shifts to meet weekly demand; or a new customer contract that adds volume without a proportional increase in SKU complexity. If your bottle formats all fall within the 700 ml and 38 mm neck diameter envelope of the 6C76, and if your current four-cavity machine is the bottleneck, the six-cavity upgrade delivers the output increase without requiring a fundamental change to your preform supply, mold design, or utility infrastructure — aside from the higher compressed air volume the additional two cavities consume.
Q5. Where can pharmaceutical packaging facilities in Latin America source a validated pet blow molding machine with technical commissioning support and local spare parts availability?
Pharmaceutical packaging facilities in Latin America — including Colombia, Brazil, and Mexico — can source validated pet blow molding machine systems through our global distribution and after-sales network. Our commissioning teams provide on-site installation, operator training, and initial production validation, ensuring that the machine meets output rate and bottle-quality specifications before the customer accepts it. Spare-parts logistics extend to Latin American facilities through scheduled shipment programs that minimize lead times for high-turnover consumables. Remote diagnostics capability allows our engineering team to access machine status data and assist with troubleshooting without the delay of an in-person visit — an important consideration for facilities that cannot afford extended unplanned downtime on a high-output blow molding machine running at 7,200 bph.
