EP-HGA.ES-2C150 Edible Oil Bottle & Handle Bottle Blow Molding Machine
The EP-HGA.ES-2C150 sits within the HGA.ES series — a product family purpose-built for the edible oil and condiment packaging market. Unlike a general-purpose pet blow molding machine, every element of this design addresses the specific demands of handle-bottle production: the clamping system accommodates integrated handle molds, the stretching mechanism handles the extra material volume required for thick-walled oil bottles, and the heating oven maintains temperature uniformity even when processing large-diameter preforms.
The two-stage blow molding approach used here separates preform injection from the blowing station, giving operators independent control over each process parameter. This separation is critical when producing 5-liter to 10-liter edible oil containers, where over-heating or under-stretching can create visible stress lines that no brand-owner will accept on a retail shelf. The centralized heating zone, combined with precisely timed distance blowing, resolves both issues by conditioning each preform evenly before it enters the blowing cavity.
With a theoretical output of 1,800 bottles per hour and a maximum container volume of 2,500 ml, the ES-2C150 suits mid-to-large bottling operations.
EP-HGA.ES-2C150 Edible Oil Bottle & Handle Bottle Blow Molding Machine
Engineered specifically for the edible oil and condiment packaging sector, the EP-HGA.ES-2C150 is a fully automatic blow molding machine capable of producing both front-handle and rear-handle PET bottles as well as large-capacity oil containers ranging from 5 liters up to 20 liters. This two-step blow molding machine integrates centralized heating with distance-blowing technology — a configuration that reduces cycle times, cuts energy overhead, and delivers consistent wall-thickness across every bottle. The machine targets manufacturers that need reliable, high-volume output for cooking oil, soy sauce, vinegar, condiment blends, and similar food-grade liquids. Built on a servo-driven platform with PLC automation and a touch-screen interface, the EP-HGA.ES-2C150 sets a clear benchmark in what a modern plastic blow molding machine should achieve: speed, precision, and repeatable quality, shift after shift.
Whether you are expanding an existing edible oil bottling line in Colombia, Southeast Asia, or anywhere across global markets, this bottle blow molding machine delivers the structural integrity and production throughput that brand-owners and contract fillers demand from a world-class blow molding machine.

Key Advantages of the EP-HGA.ES-2C150 Blow Molding Machine
What separates this pet blowing machine from standard two step blow molding machines is the engineering depth behind each subsystem. The advantages listed below are grounded in measurable design choices, not general marketing claims.
Centralized Heating + Distance Blowing
Uniform oven temperature prevents hot-spots across wide-body preforms, reducing reject rates on 2-liter and 2.5-liter edible oil bottles. Distance blowing delays cavity contact until optimal stretch ratios are reached, resulting in consistent material distribution around handle inserts.
Servo-Driven Clamping System
Servo motors replace hydraulic actuators on the clamping unit, cutting energy consumption during idle strokes and enabling precise positioning repeatability within ±0.05 mm. This directly improves bottle neck alignment on handle-bottle configurations where mold halves must meet without offset.
PLC Touch-Screen Control
An integrated PLC platform stores up to 99 mold recipes. Operators switch between bottle formats — from a 500 ml condiment jar to a full 2,500 ml oil container — in minutes. Real-time diagnostics flag pressure deviations or temperature drift before a fault stops production, protecting uptime during multi-shift runs.
Dual-Handle Compatibility
The mold clamping stroke of 190 mm accommodates both front-mounted and rear-mounted handle inserts without fixture changes, giving bottlers the flexibility to supply multiple SKUs from one auto blowing machine without investing in a second blowing station.
High-Pressure Air Efficiency
Blowing pressure adjustable from 26 to 35 kg/cm² with high-pressure air consumption in the range of 1,000–1,500 ltr/min. The closed-loop pressure recovery system returns residual blow air back to the low-pressure circuit, trimming compressed-air operating costs by a measurable margin on high-output shifts.
Compact Machine Footprint
At 4,290 × 1,800 × 2,220 mm and 3,500 kg, the ES-2C150 fits within standard factory floor allocations without requiring structural reinforcement, making it accessible to medium-scale edible oil producers in Colombia, Southeast Asia, and similar emerging markets expanding their PET bottling capacity.

Mold Engineering
The performance of any bottle blow molding machine depends heavily on mold quality. Two precision mold systems are available for the EP-HGA.ES-2C150 — each engineered to specific tolerances and material grades that support long production runs without dimensional drift.
Preform Injection Mold
- The die-lip assembly is split into two precision-fitted sections, maintaining strict coaxial alignment throughout every preform formation cycle — a design choice that directly controls wall-thickness uniformity.
- Cooling channels are routed to maximize heat extraction from the preform body, shortening cycle time without creating thermal stress points that could weaken the finished bottle.
- All forming inserts are manufactured from imported grade 2316 die steel — a material chosen for its corrosion resistance after heat treatment, which extends service life in humid production environments.
- Core plates, cavity plates, and primary structural components use 420 stainless steel, providing reliable corrosion resistance during prolonged contact with water-cooled circuits.
- Modular construction simplifies maintenance; standard interchangeable fittings mean replacement parts are sourced quickly without lengthy downtime.
- Advanced cavity layout allows a single mold to produce more than one preform variant, reducing capital investment when running multiple bottle formats on the same auto pet blowing machine.
Blowing Mold
- Cavity blocks are produced from premium-grade tool steel, selected for hardness and dimensional stability under repeated high-pressure blowing cycles at 26–35 kg/cm².
- Bottle profiles are developed using advanced 3D modeling software, ensuring accurate internal volume and even wall thickness across complex handle-bottle geometries before a single chip is cut.
- A broad portfolio of bottle styles is available, covering standard oil containers, square-profile condiment bottles, and ergonomic handle designs suited to 1-liter through 2.5-liter formats.
- Water-cooling circuits within the mold body are configured for efficient heat removal, helping maintain a stable cycle rate across extended production runs.
- Every metallic component is finish-machined on CNC equipment, providing surface tolerances that keep parting-line flash within acceptable limits and reduce post-blow trimming requirements.
Machine Structure & Technical Architecture
The EP-HGA.ES-2C150 two-step blow molding machine is structured around a rigid welded steel frame that absorbs clamping forces without transferring vibration to the heating or conveying sections. This structural isolation matters when producing handle bottles, because any vibration during preform transport causes positional errors in the handle-insert cavity that result in misaligned handles — a defect that triggers line stoppages and customer complaints. Below is a summary of the key structural zones and the engineering rationale behind each design decision.
Preform Feed System
A hopper-and-elevator arrangement delivers preforms at a controlled rate matched to the oven's capacity. Jams are detected by proximity sensors before they reach the mandrel, preventing preform deformation that would otherwise propagate through the blowing cycle.
Infrared Heating Oven
Near-infrared lamps are segmented into independent heating zones. Operators adjust each zone's output percentage to match the absorption profile of the preform wall — thicker sections in handle-bottle preforms absorb more energy and require zone-specific compensation to avoid over-heating the neck finish.
Sträckblåsstation
Mechanical stretch rods descend synchronously with the pre-blow air pulse. For 2.5-liter edible oil bottles, the stretching stroke of 450 mm provides sufficient axial orientation to develop the biaxial strength needed for stackable, drop-resistant containers.
Mold Clamping Unit
The servo-driven toggle clamp delivers consistent lock force across the full production run. A mechanical lock holds the mold closed during the high-pressure blow phase, so servo load remains low and motor heat generation stays within safe limits even during 20-hour runs.
Bottle Ejection & Transfer
Blow-formed bottles are ejected pneumatically and transferred to a take-out conveyor without operator contact, maintaining hygienic production conditions suitable for food-grade edible oil containers. The transfer speed synchronizes with the blowing cycle to prevent queuing or bottle-on-bottle collisions.
Applikationsscenarier
The EP-HGA.ES-2C150 bottle blow molding machine addresses a broad range of packaging tasks where handle-bottle integrity and food-grade material compliance are non-negotiable requirements. The following scenarios represent the primary application categories confirmed in commercial deployments of this machine.
Edible Oil Packaging
Purpose-designed for 1-liter, 1.8-liter, and 2.5-liter PET handle bottles for cooking oil, blended oil, and olive oil. The centralized heating design keeps material orientation consistent, delivering the drop-impact resistance required for filled containers shipped on mixed-product pallets.
Condiment & Sauce Bottles
Soy sauce, oyster sauce, vinegar, and specialty condiment producers use this blow molding machine to produce complex-profile PET bottles with integrated grip areas, tamper-evident neck finishes, and wide-body forms that accommodate sauce viscosity requirements and label-wrap decoration.
Food-Grade Liquid Packaging
Beyond oil and condiments, the ES-2C150 functions as a versatile food-grade pet blow molding machine suited to mineral water with handle, drinking vinegar, sports drinks in large formats, and other non-carbonated food liquids where PET clarity and safety certification matter.
Agricultural & Industrial Liquids
The robust clamping design allows production of thick-walled PET containers for agricultural chemicals, liquid fertilizers, and cleaning agents, where HDPE has traditionally dominated. PET provides superior clarity for product-level visibility and recycles cleanly within established food-packaging streams.
Household & Personal Care
Household cleaning liquids, dishwashing soap, and fabric softener producers in Colombia and other Latin American markets commonly use this type of fully automatic blow moulding machine to produce handle-grip bottles in the 1.5–2.5-liter range, where ergonomic pouring performance is a purchase driver for end-consumers.
How to Select the Right Blow Molding Machine
Choosing correctly between a single-stage and a two-stage blow molding machine, or between different models in the same series, requires matching production targets to machine capability on several dimensions simultaneously. The following checklist is drawn from real application engineering work across the edible oil, food, and condiment sectors.
| Selection Factor | What to Evaluate | ES-2C150 Position |
|---|---|---|
| Bottle volume range | Target container sizes in ml / liters | Up to 2,500 ml |
| Handle compatibility | Front, rear, or no handle | Both front and rear handles supported |
| Required output | Bottles per hour | Up to 1,800 bph |
| Material type | PET / PETG / PP compatibility | PET (primary), PETG compatible |
| Floor space | Available factory footprint | 4,290 × 1,800 mm |
| Energy budget | kW demand and utility costs | 42.5 kW max, 18 kW running heating |
| Neck diameter | Closure standard required | Up to 110 mm |
| Automation level | Operator headcount and shift coverage | Fully automatic, 1–2 operators per shift |
If your target bottle volume exceeds 2,500 ml or your output requirement surpasses 1,800 bph, the larger HGA.ES-2C200 or the HGA.FS-2C200(5L) models within the same series should be evaluated. For applications where Colombian or Latin American market bottle aesthetics require complex surface texture or embossing, a custom cavity discussion with the mold engineering team is recommended before placing an order.

Verkstad
Compatible Auxiliary Equipment
Running an EP-HGA.ES-2C150 blow molding machine at peak efficiency requires properly matched ancillary equipment. We supply and integrate the following systems as part of a complete, tested turnkey package — one supplier, one point of contact, one system warranty. This one-stop approach removes the integration risk that arises when customers source each machine independently from different vendors.
Air Compressor
High-pressure air compressors rated to deliver 26–35 kg/cm² blowing pressure and the required 1,000–1,500 ltr/min high-pressure flow. Oil-free screw and piston compressor options are available to meet food-grade compressed-air standards. System integration ensures the compressor start sequence is coordinated with the blowing machine's air demand profile, preventing pressure drops during peak cycles.
Formtemperaturregulator
Precise mold temperature management is essential for consistent bottle surface quality, particularly on handle-insert cavities where temperature imbalance causes sink marks or warped handles. Our matched mold temperature controllers maintain blow-mold surface temperatures within ±1°C, supporting stable cycle-to-cycle dimensional repeatability across the full shift.
Bottle Visual Inspection Machine
Inline camera-based inspection systems examine every bottle for surface defects, dimensional variance, and wall thinning before the container reaches the filling line. For edible oil and food-grade applications in global markets, this level of automated quality control is increasingly specified by brand-owners as a condition of supply-chain approval, making it a practical complement to this auto blowing machine installation.
Chiller & Cooling Water System
The ES-2C150 requires 30 ltr/min cooling water flow at 8–10°C and 5–6 kg/cm² operating pressure. Matched water chillers maintain these conditions consistently regardless of ambient temperature variations on the production floor, protecting both mold service life and bottle-to-bottle dimensional consistency. We supply chiller units sized specifically to this machine's thermal load, avoiding the over-engineering and wasted energy common when chillers are sourced separately.
