EP-HGA.JS-2CB152 Edible Oil Bottle & Handle Bottle Blow Molding Machine

Extended Preform Conditioning System

The 128-position heating section is one of the defining characteristics of the JS-2CB152 compared to earlier models in this series. More preform positions in the heating zone mean each preform receives a longer, more uniform thermal conditioning period before entering the blowing station. For 3 L handle oil bottles — where the preform body needs to achieve full heat penetration across a relatively thick wall — this extended dwell time produces more consistent stretch ratios and better bottle clarity than shorter heating configurations. The result is a finished container with tighter dimensional tolerances and fewer heat-related rejects per thousand bottles produced.

Dual-Cavity Output at Moderate Power Draw

At 48 kW peak heating power and 12 kW running consumption, the JS-2CB152 delivers 1,600 bph from a dual-cavity blowing station without the power infrastructure demands of larger machines. For food-grade bottle production facilities in Colombia and other Latin American markets where electrical infrastructure capacity may be a planning constraint, this power profile gives operators meaningful output at a manageable energy budget. The machine's blowing pressure of 35 kg/cm² is applied with precision timing, reducing air consumption inefficiency across the cycle.

Jump-Station Transport Architecture

The JS designation in this model's name refers to a jump-station preform transport design that decouples the heating and blowing sequences. Rather than linking each preform's movement directly to the blowing cycle, the transport system creates a buffer between the two stations, allowing the heating tunnel to operate at a consistent rate regardless of momentary variations at the blowing station. This architecture reduces the sensitivity of the overall cycle to minor timing variations and supports more stable long-run output on automatic pet blowing machine applications where continuous production shifts are standard.

Front & Rear Handle Bottle Capability

Like other models in this edible oil bottle series, the JS-2CB152 is configured to handle both front-handle and rear-handle bottle profiles. Handle geometry at the 3 L scale requires specific stretch rod timing and blowing pressure curve optimization, all of which are set up in the PLC control system and can be saved as named production recipes. Switching between handle profiles requires a mold change and parameter recall rather than mechanical reconfiguration of the machine — minimizing transition time between SKUs on the same production line.

Preform Injection Mold

• The gate lip is engineered as a two-piece interlocking assembly, a construction that maintains coaxial alignment between the core and cavity throughout the injection fill and packing stages — the primary mechanical factor controlling preform concentricity.
• Cooling channels are routed to achieve full-length preform coverage, maximizing heat extraction rate during the cooling phase and enabling shorter cycle times without compromising the dimensional stability of the ejected preform.
• All cavity-forming components are machined from imported 2316 die steel — a grade chosen for its proven corrosion resistance and the consistent hardness it achieves after heat treatment, supporting long service life in continuous production environments.
• Core and cavity plates are fabricated from 420 stainless steel, providing additional protection against the moisture and chemical exposure common in food packaging production facilities.
• Maintenance access is built into the mold architecture, with components sized and positioned to allow removal and replacement without requiring specialized equipment or extended downtime.
• All fittings use industry-standard interchangeable specifications, and the mold cavity layout supports production of multiple preform neck sizes from a single tool configuration.

Blowing Mold

• Mold bodies are produced from premium tool steel grades selected for hardness and machinability at the 35 kg/cm² blowing pressures and container sizes used in this production range.
• All bottle cavity geometries are developed in advanced 3D modeling software, ensuring that draft angles, handle sweep geometry, and base dome profiles are optimized for clean, consistent demolding of each container variant.
• A library of proven handle bottle and standard oil bottle designs is available for selection, giving buyers a faster path to production start than a fully custom mold design project would require.
• Internal cooling circuit routing prioritizes heat extraction from the thickest regions of each container — typically the base and handle attachment zones — to maintain consistent mold surface temperatures during long production runs.
• Every structural mold component is finish-machined on CNC equipment to tolerances that ensure repeatable parting-line contact and eliminate flash on the finished bottle across the full production life of the tool.

1 L – 3 L Cooking Oil Bottles

The JS-2CB152 blow molding machine's 3,000 ml volume ceiling and 330 mm maximum container height cover the full range of standard retail cooking oil formats sold in Latin American markets. In Colombia and neighboring countries, 1 L, 2 L, and 3 L handle oil bottles represent the dominant retail packaging formats across both supermarket and traditional trade channels.

Condiment & Sauce Packaging

Wide-body PET containers up to 140 mm in diameter produced on this plastic blow molding machine accommodate standard closure formats used for soy sauce, vinegar, hot sauce, and similar condiment products. The neck diameter of 46 mm is typical for the common screw-cap finish used across this product category in global markets.

Household & Personal Care Liquids

The handle bottle geometry produced on this auto blowing machine is equally applicable to household cleaning products, liquid soap, shampoo, and fabric care products in the 1–3 L size range. Mold changeover allows operators to run multiple product categories on the same machine across different production shifts.

Pharmaceutical & Food-Grade Liquids

PET containers produced on food-grade blow molding machines in this series meet the material purity requirements for pharmaceutical liquid packaging and food-contact applications. The 8–12 °C cooling water circuit maintains mold surface temperature within the range required for container dimensional stability in these regulated sectors.

Industrial & Automotive Fluids

At blowing pressures up to 35 kg/cm², the JS-2CB152 can produce PET containers with the wall thickness specifications required for motor oil, hydraulic fluid, and similar industrial liquids. Container robustness at this format is particularly important for the automotive after-market channel, where containers must survive warehouse stacking loads without deformation.

Automated Preform Feeder

The inclined hopper and conveyor system delivers preforms to the heating zone at a consistent feed rate matched to the machine's 1,600 bph cycle. Orientation guides prevent misaligned preforms from reaching the heating spindles, protecting the tooling and maintaining output continuity across multi-hour production runs.

128-Position Infrared Heating System

The 128-position heating section uses zoned infrared lamps with independent temperature control per zone. The extended preform capacity means each preform spends more time in the tunnel than in shorter configurations, enabling deeper, more uniform heat penetration across the full preform body — critical for producing 3 L handle bottles with consistent wall thickness in the grip and shoulder areas.

Dual-Cavity Blowing Station

The blowing station operates with two cavities per cycle at up to 35 kg/cm² blowing pressure. Stretch rods are mechanically synchronized with the air injection sequence to ensure the axial and radial expansion of the preform happens in the correct ratio for each container geometry. The blowing pressure profile is programmable per bottle type and stored in the PLC control system.

PLC Touchscreen Control

The control panel provides a full touchscreen interface for setting and saving production parameters by container model. Alarm outputs for heating zone deviation, pressure drop, and mechanical fault conditions keep operators informed during unmanned production periods. Production data including output count, cycle time, and reject event logs can be reviewed for quality control purposes.

Air Compressor

Oil-free high-pressure compressors matched to the JS-2CB152's 35 kg/cm² blowing requirement and 3,600 L/min high-pressure air consumption. Oil-free specification is a requirement for food-grade container production — oil carry-over from a standard compressor can contaminate the interior of finished bottles and create compliance issues in regulated markets.

Mold Temperature Controller

Precise temperature control units maintain the blowing mold at 8–12 °C throughout production. At the JS-2CB152's output rate, consistent mold temperature is the primary factor controlling cycle-to-cycle dimensional repeatability — a mold that drifts above its target temperature produces bottles with progressively more variation in base diameter and shoulder geometry as the shift progresses.

Bottle Visual Inspection Machine

Automated optical inspection equipment downstream of the blowing molding machine identifies surface defects, wall-thickness anomalies, and incomplete bottle formation before containers reach the filling station. For edible oil and food-grade applications, 100% inspection at the blowing stage is a best-practice quality control measure in export-oriented production operations.

Industrial Chiller

A dedicated industrial chiller maintains the 60 L/min cooling water supply at 8–12 °C. Undersized or unstable chiller capacity is one of the more common causes of extended cycle times and reject spikes in blow molding operations — sizing the chiller to 120% of the machine's rated flow requirement provides the headroom needed to maintain stable mold temperature during peak production conditions.
