EP-HGA.ES-2C200 — Large-Volume Wide-Mouth Food Jar & Can Blow Molding Machine

 5,000 ml Container Capacity

The 5,000 ml volume ceiling and 180 mm maximum body diameter mean this blow molding machine covers every standard large-format jar size in the food, condiment, and supplement segments — from 2-litre peanut butter tubs to 5-litre institutional edible-oil jugs — without requiring separate equipment for different size tiers.

 85 kW High-Power Heating

Conditioning large-wall-weight preforms to a uniform blowing temperature demands substantially more infrared heating energy than smaller jar formats. The 85 kW maximum heating power — supplemented by a 35 kW auxiliary module — provides the thermal capacity to handle the heaviest preform specifications in the ES-2C200's container range without oven speed compromises.

 500 mm Stretch Rod Travel

The extended 500 mm stretch stroke enables full axial orientation of preforms for containers up to 350 mm in height — a requirement for the tall cylindrical jar formats used in protein powder and institutional condiment packaging, where incomplete stretching would leave an unoriented base zone prone to stress cracking under filled-container top-load conditions.

Dual-Cavity Efficiency

Two blow cavities operating in each cycle produce 1,600 containers per hour — a rate that makes large-format jar production economically viable as a primary output format rather than a niche capacity addition. For auto blowing machine operators in Colombia and Latin America, this output level opens large-format jar packaging to converters who previously relied on imported glass or metal containers due to insufficient domestic plastic-jar production capacity.

138 mm Wide Neck Support

The 138 mm maximum neck diameter is the widest available in the standard ES-2C series, accommodating the large-opening jar formats required for dry goods, granular products, and high-viscosity fills where a narrower neck would impede filling speed or create bridging issues on automated filling lines.

 Incision-Free Can Capability

Like the rest of the ES-2C series, the ES-2C200 supports the automatic incision-free wide-mouth can blowing process. Containers exit the mold with a fully finished neck surface — no trimming, no secondary cutting step — keeping the production chain as short as possible and eliminating the dimensional scatter that cutting operations introduce on neck sealing surfaces.

Preform Injection Mold

The gate bushing is machined as a two-segment assembly that enforces perfect axial alignment of the preform throughout the injection cycle. In large-wall-weight preforms for 5,000 ml containers, even minor gate offset results in wall-thickness asymmetry that amplifies during stretching — making coaxial gate design a prerequisite rather than a preference at this container scale.

Cooling channels are engineered to deliver maximum thermal extraction throughout the preform body, including at the thick base section where heat concentration is highest in heavy-weight preforms. Fast, even cooling shortens cycle time without leaving temperature gradients that cause post-ejection distortion of the preform's wide neck finish.

Cavity inserts are manufactured from imported grade 2316 die steel, which provides corrosion resistance as a base material property rather than a surface treatment, and undergoes controlled heat treatment to the hardness range required for sustained high-volume production without cavity surface wear.

Core plates, cavity plates, and all load-path structural components are produced from 420-grade stainless steel — the grade typically specified for mold structures that operate in persistently humid or thermally cycled industrial environments.

Standardized interchangeable die fittings throughout the mold simplify spare-parts procurement across global markets. The tooling base design accommodates multiple neck-finish standards — useful for operations that need to cover both domestic and export container specifications from the same injection mold frame.

Blowing Mold

Blow cavity blocks are forged from premium tooling steel selected for its hardness-to-thermal-conductivity balance — a trade-off that becomes more pronounced in large-cavity molds where the heat load per cycle is higher and where insufficient conductivity results in uneven cooling across the wide base and shoulder zones of the container.

3D CAD modeling is used for every container profile from the outset, with flow simulation validating the wall-distribution behavior before any cavity machining begins. For 5,000 ml containers, where tooling costs are significant, eliminating avoidable rework through pre-machining simulation is a direct cost protection for the customer.

A selection of validated large-format jar templates covers the most common food-jar profiles in the 2,000–5,000 ml range, including round-base canisters, flat-shoulder containers, and wide-flange-lid formats used in institutional food-service packaging across Colombia and export markets.

The cooling-water circuit is balanced to maintain uniform temperature across the full mold face area — particularly important in large cavities where the temperature differential between the bottom and the shoulder can be significant enough to affect surface gloss consistency across the container body.

All metal components, including the large-diameter neck rings and base plugs that are unique to this container class, are finish-machined on CNC milling and turning centers, holding the geometric tolerances that incision-free can neck finishing and automated capping sequences require.

Bulk Edible Oil

Large-format PET containers for 3-litre and 5-litre retail edible-oil SKUs, where biaxial molecular orientation from the stretch-blow process delivers superior top-load performance compared to extrusion-blown HDPE alternatives. The clear PET wall also enables the oil-clarity quality-check that premium oil brands use as a visual selling point in Colombian and Andean supermarkets.

Institutional Condiments

Wide-mouth 2,000–5,000 ml containers for bulk mayonnaise, ketchup, hot sauce, and salad dressing supplied to catering operations, restaurant chains, and school meal programs across Latin America. The wide neck diameter of up to 138 mm accommodates high-viscosity fills at the flow rates institutional filling lines require.

Bulk Dried Fruits & Snacks

Large canisters for dried fruits, mixed nuts, granola, and trail mix sold in club-store formats and bulk retail channels. The incision-free wide-mouth neck provides a hermetic induction-seal surface that maintains freshness equivalent to glass or metal packaging at a fraction of the container weight and breakage risk.

Protein & Supplement Powders

Large-format PETG containers for protein powders, meal-replacement blends, and granular vitamin supplements where the wide scoop-access opening requires a 100+ mm neck and where the container must withstand repeated opening and closing without neck-thread fatigue. PETG's non-crystallizing structure is preferred for the heavy neck-finish area in this application.

Agricultural & Industrial Food-Grade

5-litre containers for food-grade agricultural inputs, concentrated flavoring agents, and industrial food-processing liquids where FDA-compliant PET, easy chemical identification through clear walls, and stackable rectangular profiles for efficient warehouse storage are all required simultaneously — applications growing in the Colombian agri-food export sector.

Heavy-Section Machine Bed

At 4,500 kg, the machine itself reflects the structural mass required to handle the clamping forces generated by large-area blow molds. The welded steel bed undergoes post-weld stress relief before machining of all locating surfaces, ensuring the mold parallelism that dual-cavity wide-mouth production requires is held from day one and maintained across years of production.

Extended Infrared Oven

The heating oven is configured with sufficient lamp zones and oven length to condition 50 preforms concurrently — a capacity matched to the heavier preform weights required for 5,000 ml containers, where each preform needs more thermal energy input and more time to reach a uniform blowing temperature across its full wall cross-section.

High-Flow Cooling Circuit

The 91.4 ltr/min cooling-water flow rate — the highest in the ES-2C series — reflects the greater heat content that large-volume containers carry out of the blow mold. Adequate flow ensures the mold returns to its set temperature between cycles, preventing the gradual temperature drift that causes gloss and dimensional variation to develop during extended production runs.

Independent Air-Pressure Regulation

The pre-blow and final-blow stages operate on entirely separate regulated circuits, with the final-blow pressure operating at 30 kg/cm². For 5,000 ml containers with wide body diameters, the pre-blow timing and pressure control the initial lateral expansion of the preform and directly determine whether the base gate area forms correctly before the high-pressure stage completes the shoulder and body geometry.

High-pressure oil-free compressors sized for the ES-2C200's 6,000 ltr/min high-pressure demand at 30 kg/cm². Oil-free technology is mandatory for food-grade jar production where any lubrication carryover into the container interior would compromise food safety certification and regulatory compliance in Colombia and export markets.

Precision water-circulation mold temperature controllers maintain each blow cavity at a stable set temperature throughout the production shift. At the large cavity areas involved in 5,000 ml jar production, even a 3°C cavity temperature rise can shift wall thickness distribution measurably, affecting top-load test results on fully filled containers.

Inline optical inspection systems scan each large-format jar for base-gate defects, thin-wall zones, contamination, and neck-finish dimensional deviations at full production speed. For food-grade large-jar lines supplying Colombian supermarkets or export clients with HACCP requirements, this inspection step provides the traceability records that quality audits require.

We supply matched industrial chillers delivering 91.4 ltr/min of cooling water at 8–12°C — precisely the flow rate and temperature the ES-2C200 specifies — combined with oil-free compressed-air generation and treatment as a single utility skid. For new factory installations in Colombia and Latin America, this integrated utility supply simplifies site engineering and procurement.
