EP-HGA.J-2C366(20L) Edible Oil Bottle & Handle Bottle Blow Molding Machine
The 332 mm clamping stroke, 772 mm mold-open distance, and 620 mm stretching stroke are among the largest parameters in any commercially available two-stage blow molding machine for PET oil containers, and they are what allow the machine to consistently produce 20 L containers up to 480 mm tall and 300 mm in diameter without mechanical strain or cycle instability.
The theoretical output of 700 bottles per hour reflects the longer cycle time inherent in blowing and cooling containers of this volume. At 22,000 ml of internal volume, each blowing cycle requires 12,500 L/min of high-pressure air at 35 kg/cm² — figures that underscore why compressor selection for this machine requires careful engineering, not a generic specification. The cooling water circuit runs at 120 L/min to maintain the mold surface at 8–12 °C, and 86 kW of peak heating capacity — 45 kW running — conditions the 116-position preform load to the temperatures required for consistent wall-thickness distribution across containers of this size.
EP-HGA.J-2C366(20L) Edible Oil Bottle & Handle Bottle Blow Molding Machine
Two-Step Blow Molding Machine | Fully Automatic | Up to 20 L | Heavy-Duty Large-Capacity PET Container Production
The EP-HGA.J-2C366(20L) is the highest-capacity model in the edible oil and handle bottle blow molding machine series. With a maximum container volume of 22,000 ml and a 772 mm mold-open distance — the largest in the series — this fully automatic blow moulding machine is engineered specifically for the production of large-format PET oil containers: 10 L, 15 L, and 20 L bulk oil jugs and handle bottles used in commercial foodservice, institutional supply, and industrial distribution channels. The machine's 366 mm bottle mold-close distance and 620 mm stretching stroke reflect the scale of container it handles, and every system on the machine — heating, air, cooling, and clamping — is sized for sustained large-format production rather than adapted from a smaller design.

Key Advantages of the EP-HGA.J-2C366(20L) Blow Molding Machine
22,000 ml Maximum Container Volume
No other model in this series approaches the J-2C366(20L) in terms of raw container capacity. The 22,000 ml rated maximum covers the full range of commercial and industrial bulk oil container formats: 10 L, 15 L, and 20 L PET jugs used across foodservice, wholesale distribution, and industrial supply channels globally. Achieving this volume requires a 772 mm mold-open distance — nearly double the corresponding figure on the ES-2C130 — and a clamping system engineered to maintain precise mold closure force across the full container height of up to 480 mm.
620 mm Stretching Stroke for Large PET Containers
Biaxial stretch ratios for 20 L PET containers are substantially higher than for smaller bottles, and the stretch rod travel distance must match the container height to achieve the molecular orientation that gives PET its barrier properties and drop resistance. The 620 mm stretching stroke on the J-2C366(20L) is specifically sized for this container length, ensuring that the axial stretch phase completes correctly before the radial blowing phase begins — a sequence precision that directly affects whether the finished container passes stacking load, drop test, and oxygen permeation specifications.
116-Position Preform Heating System
Preforms for 10–20 L PET containers are among the heaviest used in any commercial pet blow molding machine application, often exceeding 300 g. Thorough heat penetration across a preform of this wall thickness requires extended dwell time in the heating zone. The 116-position infrared heating system on this machine provides this dwell time without compromising throughput, delivering fully conditioned preforms to the blowing station at the cycle rate needed to achieve the machine's rated 700 bph output under sustained production conditions.
Heavy-Duty Construction for Continuous Operation
At 7,000 kg machine weight and 3,040 mm height, the J-2C366(20L) is built to handle the mechanical loads generated by blowing 20 L containers at 35 kg/cm² blowing pressure and 12,500 L/min air flow. The machine frame, clamping mechanism, and blowing station are all sized with substantial safety margins for continuous multi-shift operation — the operational model typical of large-format oil container production in commercial and industrial bottling facilities.

Mold Engineering for Large-Format Containers
Preform Injection Mold

- The gate area is built as two separate interlocking sections — a design choice that keeps the preform body centered on its axis throughout the entire injection, packing, and cooling sequence, which is particularly important for heavy preforms where any eccentricity amplifies wall-thickness variation in the finished 20 L container.
- Water channels are positioned to cover the full preform body, maximizing cooling efficiency and reducing the time each preform spends in the cavity — a direct contribution to overall machine cycle rate.
- Forming inserts are machined from imported 2316 die steel, heat-treated for consistent hardness and chosen specifically for its corrosion resistance under the sustained production conditions of large-preform injection molding.
- Core plates, cavity plates, and load-bearing structural components are produced from 420 stainless steel, chosen for its resistance to corrosion in the humid production environments where food packaging equipment typically operates.
- The mold is laid out for efficient service access, with modular component design that reduces maintenance time compared to traditional one-piece cavity configurations.
- All fittings conform to standardized interchangeable specifications, and the mold cavity layout accommodates more than one preform body length from the same tooling — reducing the mold investment required when producing containers across the 10–20 L volume range.
Blowing Mold

- Mold bodies are produced from premium tool steel grades engineered for the combination of high blowing pressure (35 kg/cm²) and large contact area that 20 L container cavities require — dimensional stability under repeated thermal and mechanical cycling is the primary selection criterion.
- All container cavity profiles are developed in precision 3D CAD/CAM software, capturing the handle geometry, body taper, base design, and neck finish details that define functional performance and aesthetic quality in the finished container.
- Multiple 20 L container profiles are available — including straight-body jugs, tapered handle jugs, and specific regional format variants — allowing buyers to select the container geometry most suited to their market distribution requirements.
- Internal cooling circuits are engineered to prioritize heat extraction from the base and handle attachment areas, where material accumulation is greatest and the risk of retained heat-induced deformation is highest after the blowing cycle.
- All mold structural components are finish-machined on CNC equipment to tight tolerances. For containers of this size, parting-line precision is directly visible on the finished product — CNC machining ensures consistent cavity contact and eliminates the flash lines that manual machining methods cannot reliably prevent at large container dimensions.

Blow Molding Machine Application Scenarios
10 L & 20 L Bulk Edible Oil
The primary application for this machine is the production of 10 L and 20 L PET oil containers used in foodservice distribution, wholesale clubs, and institutional purchasing programs. In Colombia, Brazil, and across Latin America, bulk oil in 10–20 L containers is the standard format for restaurant, hotel, canteen, and industrial catering procurement.
Industrial Lubricants & Chemicals
20 L PET containers produced on this bottle blow molding machine serve the industrial lubricant, hydraulic oil, and specialty chemical markets. The biaxial PET orientation produced during the stretch-blow process gives the container the mechanical strength needed to withstand the stacking and handling loads typical of industrial supply chain logistics.
Water Dispensing Containers
In markets where PET is the accepted material for large-format water dispensing containers, the J-2C366(20L) produces containers that meet the dimensional standards required for standard dispenser neck formats. The 90 mm neck diameter range accommodates the most common dispenser cap sizes in use across tropical and subtropical markets.
Agricultural Input Packaging
Liquid fertilizers, pesticide concentrates, and agricultural adjuvants are commonly packaged in 10–20 L containers for efficient distribution to large-scale farming operations. The rigidity and chemical compatibility of PET containers produced on this plastic blow molding machine meet the requirements of most agricultural liquid input applications.
Bulk Cleaning & Sanitation Products
Institutional-grade cleaning concentrates, disinfectants, and sanitizer solutions are distributed in 10–20 L containers across healthcare, hospitality, and food processing sectors. The 300 mm maximum container diameter and 480 mm maximum height cover the standard formats used in these markets globally.
How to Select the Right Blow Molding Machine for Large-Format Oil Container Production
The EP-HGA.J-2C366(20L) is the appropriate choice when your primary production target is containers in the 10–20 L range. If your containers are consistently below 5 L, this machine will be overspecified for your needs — the ES-2C200 or JS-2C200 models serve those sizes more efficiently. The J-2C366(20L) makes practical sense when daily output of large-format containers at 700 bph across single or multiple shifts generates the volume your distribution operation requires. Below that threshold, a smaller-format blow molding machine running 5 L containers may generate equivalent product volume at lower capital and utility cost.
Preform selection for 20 L containers is a significant engineering decision. Preform weight typically falls in the 300–450 g range depending on the container wall specification, and sourcing preforms of this size requires either a dedicated injection molding machine or a specialized preform supplier with large-format capability. Before specifying the J-2C366(20L), confirming your preform supply chain is essential — the two-step blow molding machine approach depends entirely on the availability of correctly specified preforms at the volumes your production schedule requires.
Facility planning for this machine requires careful attention to floor loading (7,000 kg machine weight plus ancillary equipment), ceiling height (the machine stands 3,040 mm tall), utility supply (86 kW electrical, 12,500 L/min HP air at 35 kg/cm², 120 L/min cooling water), and output handling — 700 bottles per hour of 20 L containers generates significant conveyor and storage volume that must be planned into the facility layout before installation. We provide full engineering documentation for all of these planning requirements as part of the project process for buyers in Colombia, Latin America, and global export markets.
Core Machine Systems
Heavy-Duty Preform Feed System
The preform conveyor and orientation system is reinforced for the weight and dimensions of large-format PET preforms. Preform body length for 20 L containers significantly exceeds that of standard beverage preforms, requiring longer guide rail geometry and more robust spindle engagement to maintain reliable orientation through the entire heating zone entry process.
Multi-Zone Infrared Heating Tunnel
The 116-position heating system uses independently controlled infrared zones to build a custom temperature profile across each preform. For 20 L bottle preforms, achieving uniform heat penetration from the surface to the core of the preform wall is the primary thermal challenge — the extended heating section and zone-by-zone control provide the tool to manage it precisely.
High-Flow Blowing Station
The blowing station operates at 35 kg/cm² with a high-pressure air consumption of 12,500 L/min — the highest in the series. The station's air valve sequencing and stretch rod timing are calibrated for 20 L container geometry, with the 620 mm stretch rod travel matched to the container height range. The dual-cavity configuration blows two containers per cycle at the rated 700 bph throughput.
PLC Control & Production Monitoring
The touchscreen PLC control system manages all machine functions — heating profiles, blowing pressure curves, stretch rod timing, mold clamping force, and cooling circuit monitoring. For large-format container production where each defective bottle represents a proportionally larger material loss than at smaller formats, the alarm and rejection logic is particularly valuable in maintaining quality across long production runs.

About Us
We manufacture blow molding machines with a focused specialization in PET stretch blow molding technology across a container volume range from 50 ml to 22,000 ml. The J-2C366(20L) represents the upper end of this range — a machine that we have developed and refined over multiple production generations to address the specific technical demands of large-format PET container production. Every machine in our program, including this one, is tested at full production speed at the factory before shipment, generating actual container samples that are reviewed for dimensional conformance and visual quality before the machine is released for delivery.
Our blow molding machine product range also includes single-stage injection stretch blow molding machines, standard two-step models for smaller container formats, and specialized configurations for cosmetics, pharmaceutical, and beverage packaging. If your operation requires multiple container formats, we can configure a production program that covers your full range with matched equipment from the same technical platform.
Workshop




Auxiliary Equipment for a Complete Production Line
A large-capacity blow molding machine at the J-2C366(20L) scale requires matched auxiliary systems sized for its specific utility demands. We supply or source all of the following to support single-supplier project delivery.
Air Compressor
Oil-free high-pressure compressors rated to 35 kg/cm² at 12,500 L/min to match the J-2C366(20L)'s blowing air demand. At this consumption level, compressor sizing and redundancy planning are critical engineering decisions — a compressor undersized by 20% at this flow rate will limit machine output and cause pressure instability during the blowing cycle.

Mold Temperature Controller
Precision temperature control units sized for the mold's 120 L/min cooling circuit flow rate. At 20 L container volume, the thermal mass of each container cycle is significantly greater than at smaller formats, making stable mold temperature control more — not less — important for maintaining consistent cycle-to-cycle dimensional results.

Bottle Visual Inspection Machine
At 20 L container size, each defective bottle rejected downstream represents more material loss and more filling-line disruption than at smaller formats. Automated inspection systems positioned immediately after the blowing machine output conveyor provide the earliest possible defect detection point, reducing the cost impact of any quality event on the production shift.

Industrial Chiller
Chillers rated for 120 L/min at 8–12 °C maintain the mold cooling circuit at the temperature required for rapid container set after the blowing cycle. For large containers, the cooling phase is a proportionally larger fraction of the total cycle time — a chiller that maintains stable outlet temperature reduces the variability in cooling time and helps achieve consistent 700 bph output across multi-hour production runs.
