EP-HGA.JS-2C200 Edible Oil Bottle & Handle Bottle Blow Molding Machine

Dual-Station Heating Architecture

The JS-series design combines a blowing station (8 preform holders) with a separate temperature-raising station (128 preform positions). This dual-station arrangement allows heavy 5-liter preforms to undergo a longer, more controlled conditioning cycle before entering the 2-cavity blow mold — addressing the fundamental challenge of achieving even heat penetration through the thick walls of large oil-bottle preforms without over-heating the neck finish area.

Wide-Neck Handle Bottle Compatibility

A neck diameter range of 58 mm covers the wide-finish closures used on standard 5-liter cooking oil pour-spout bottles widely distributed in Colombian supermarkets and Latin American food-service supply chains. The 225 mm clamping stroke and 509 mm mold-open distance accommodate the large tooling profiles of both front-handle and rear-handle 5-liter bottle molds without requiring custom machine modifications.

35 kg/cm² Blowing Pressure

The blowing pressure of 35 kg/cm² is one of the highest in the HGA series, delivering the forming force required to fully expand 5-liter PET preforms against large-cavity mold walls in a single blow phase. Higher forming pressure reduces the risk of under-blow defects — the most common quality failure on large-format containers where the expanding PET must travel greater radial distances to fill the mold corner radii of handle-bottle geometries.

Compact Machine Weight

At 2,500 kg, the JS-2C200 is notably lighter than other 5-liter blow molding machines in its class. This weight advantage simplifies installation on existing facility floors without structural reinforcement requirements, and reduces transportation logistics costs for customers importing the machine into Colombia, Southeast Asia, or the Middle East — markets where import logistics add meaningfully to total project cost.

Efficient Running Heating Power

While the maximum installed heating power is 65 kW, the running heating power of just 26 kW reflects the thermal efficiency of the dual-station design. The temperature-raising station pre-conditions preforms continuously, so the blowing station's heating demand remains low — translating into lower electricity costs per bottle during sustained multi-shift production runs compared with machines of comparable output capacity that rely on a single continuous oven.

PLC Multi-Recipe Control

The fully automatic blow moulding machine stores multiple production recipes via PLC, enabling rapid changeover between 3-liter, 4-liter, and 5-liter bottle programs within a single shift. Operators select the stored recipe from the touch-screen panel, and the machine automatically adjusts temperature zone set-points, stretch rod travel, and pre-blow air timing — minimizing the operator skill requirement for format changes and protecting production uptime across mixed-SKU scheduling.

Preform Injection Mold

• The die-lip assembly is built in two precision-fitted halves, maintaining strict axial alignment through every preform injection cycle to keep wall-thickness variation within tight limits before the blowing phase begins.
• Cooling water channels follow an optimized routing path that extracts heat from the preform body quickly and uniformly, supporting faster cycle rates without creating thermal stress concentrations that would weaken the preform shoulder or body.
• All cavity-forming inserts are machined from imported grade 2316 die steel, which provides corrosion resistance after heat treatment — an important material property in environments where the mold cooling circuit operates continuously against the insert surfaces.
• Core plates, cavity plates, and structural components are manufactured in 420 stainless steel to maintain long-term corrosion resistance at the cooling-water contact surfaces within the mold body.
• Assembly uses standard interchangeable fittings throughout, so maintenance or wear-component replacement can be completed without returning the full mold assembly to the manufacturer.
• The cavity geometry is arranged to allow more than one preform neck standard to be produced within the same mold body, which reduces tooling investment when the production schedule covers multiple 5-liter bottle closure formats.

Blowing Mold

• Cavity blocks are produced from high-grade tool steel selected for hardness and dimensional stability under sustained 35 kg/cm² blowing pressure — the operating condition that governs cavity wear rate and service life in high-output production environments.
• All bottle profiles are developed using advanced 3D design software before machining, ensuring that internal volume accuracy and wall-thickness distribution across complex handle-bottle geometries are validated virtually before any cutting begins.
• Multiple bottle design options are available across the 3-liter to 5-liter size range, including round-body, square-body, and ergonomic-handle variants suited to the retail and food-service edible oil formats demanded by buyers in Colombia and international markets.
• Cooling channels embedded in the cavity walls are routed to handle the elevated heat removal load of large-volume PET bottles, maintaining a stable blow cycle even at the rated 1,000 bph output.
• All metal components are finish-machined on CNC equipment, maintaining the surface tolerances that keep parting-line flash at the mold seam within acceptable limits for food-grade edible oil containers.

Temperature-Raising Station

The dedicated temperature-raising station holds 128 preform mandrel positions, providing a long conditioning dwell time that allows heat to penetrate evenly through thick-wall 5-liter preforms. Independent zone control on the infrared lamp banks in this station allows the heat profile to be tuned to the wall thickness gradient of specific preform geometries, preventing the axial temperature non-uniformity that causes wall thinning in the body of large-format oil bottles.

Blowing Station (8-Position Carousel)

The blowing station operates as an 8-position carousel, transferring pre-conditioned preforms from the temperature-raising station into the 2-cavity blow mold at the precise moment each preform reaches its target temperature profile. Separating the temperature conditioning function from the blowing station allows the blow cycle timing to be optimized independently, without the heating dwell time constraining the cycle rate or vice versa.

Servo Clamping Unit

Servo-actuated toggle clamping delivers consistent lock force at the 225 mm clamping stroke required for 5-liter handle-bottle tooling. A mechanical clamp-lock engages at full closure before the 35 kg/cm² blow pressure is applied, protecting the servo motor from sustained torque loading during the blow phase and reducing thermal generation in the drive system during extended runs.

450 mm Stretch Rod

The 450 mm stretch rod travel provides the axial elongation needed to orient PET material in 5-liter oil bottles before the main blow phase. Mechanical rod descent is synchronized with the pre-blow pulse timing stored in the recipe, ensuring the correct biaxial orientation sequence — axial first, then radial — that gives large oil containers their drop-impact and top-load stacking performance.

Pneumatic Ejection System

Completed 5-liter bottles are ejected from the blow station pneumatically and transferred to the take-out conveyor without manual handling. This contactless transfer maintains the hygienic production conditions required for food-grade edible oil containers and prevents deformation of freshly-blown large-volume bottles before they have fully cooled to dimensional stability after ejection from the mold cavity.

5-Liter Cooking Oil Containers

The primary deployment category — 5-liter PET handle bottles for cooking oil, blended vegetable oil, and palm oil — where the machine's wide-neck compatibility (58 mm), large body diameter (180 mm), and 340 mm container height cover the standard physical envelope of 5-liter oil retail formats distributed through supermarkets and wholesale clubs in Colombia and across Latin America.

Wide-Neck Condiment Jars

The 58 mm neck diameter opens the JS-2C200 to wide-mouth condiment jar production — kimchi paste containers, bulk peanut butter, wide-mouth olive oil dispensers, and similarly wide-finish food containers where the neck opening is a functional requirement of the product's intended use and dispensing method, not a cosmetic choice.

Food-Service Liquid Packaging

Food-service distributors supplying restaurants and commercial kitchens increasingly specify 5-liter PET containers for edible oils, sauces, and concentrated flavorings. PET's clarity allows kitchen staff to monitor product levels, and its lighter weight versus glass or HDPE reduces handling fatigue on high-volume lines. This bottle blow molding machine produces the food-contact-compliant PET containers this channel requires.

Bulk Household Liquids

5-liter handle-bottle formats for household cleaning liquids, laundry products, and fabric softeners in Colombian and Latin American markets are well within the JS-2C200's production envelope. The dual-handle mold compatibility and large container capacity allow household-chemical producers to consolidate multiple SKU formats onto a single auto blowing machine platform.

Specialty Liquid Chemicals

The high blowing pressure of 35 kg/cm² and the dual-station conditioning system make this blow molding machine suited to thick-walled PET containers for agricultural chemicals, liquid fertilizers, and specialty industrial liquids where wall thickness and drop resistance requirements go beyond standard food-packaging specifications.

Air Compressor

The JS-2C200 requires 2,800 ltr/min high-pressure air at 35 kg/cm² blowing pressure. For edible oil and food-grade PET bottle production, the compressor type must be oil-free — either a screw or piston variant — to eliminate contamination risk in the high-pressure air circuit that contacts the interior of food-contact containers. We supply oil-free compressor packages sized and integrated specifically to this machine's demand profile, with the system start-up sequence coordinated through the machine PLC to prevent blowing pressure drops during peak cycle demand.

Controlador de temperatura do molde

Cavity surface temperature uniformity on large-volume molds is harder to maintain than on compact molds, because the greater cavity surface area creates more points where temperature variation can influence bottle wall thickness and post-blow dimensional stability. Our matched mold temperature controllers circulate controlled-temperature fluid through the mold cooling channels at stable pressure, holding surface temperature within ±1°C across the full cavity to support consistent cycle-to-cycle dimensional repeatability at the rated 1,000 bph production rate.

Bottle Visual Inspection Machine

Inline camera inspection systems examine every 5-liter bottle for surface defects, dimensional out-of-tolerance conditions, and wall thinning before containers proceed to the filling and capping stations. For branded edible oil customers supplying major retail chains in Colombia and international markets, automated visual inspection is increasingly a mandatory supply-chain audit requirement, and integrating it directly into the production line prevents defective bottles from reaching the filling stage where contamination risk and rework cost increase substantially.
