Edible Oil and Handle Bottle Blow Molding Machine

How Does the EPA.ES-2C150 Two-Stage Blow Molding Machine Work

Step 1: Raw Material Preparation

The blow molding machine process begins with rigorous raw material preparation. PET, PP, or PE pellets are thoroughly screened, blended, dried, and fed into the injection unit. Moisture content is carefully controlled, typically to below 50 ppm for PET, to prevent hydrolytic degradation. Only after strict verification of material properties are the pellets advanced to the melting and plasticizing stages, ensuring a consistent melt that will produce preforms of uniform density and transparency throughout the production run.

Step 2: Injection Molding of Preforms

During the injection molding phase, the prepared and melted plastic is injected under precisely controlled pressure and temperature into a multi-cavity preform mold. Parameters such as melt temperature, injection speed, holding pressure, and cooling time are tightly managed by the PLC system. The result is a batch of geometrically accurate preforms with well-formed neck threads and consistent wall thickness. This stage is foundational to the quality of every bottle produced by this two-stage blow molding machine.

Step 3: Preform Preheating

Before blow molding, all preforms pass through a multi-zone infrared heating oven where their body temperature is elevated uniformly to the glass-transition range, typically 90–110°C for PET. The oven design of this EPA.ES-2C150 features zone-by-zone temperature control, with cooling air directed at the neck thread area to preserve dimensional accuracy. Uniform preform temperature distribution at this stage is critical: it determines whether the bottle will stretch evenly and prevents localized thinning or opacity that would reduce the finished product's quality and shelf appeal.

Step 4: Stretch Blow Molding

The preheated preform is transferred into the blow mold station, where a stretch rod extends it axially to the full container height while high-pressure air at 26–35 kg/cm² simultaneously expands it radially to fill the mold cavity. This biaxial stretching process, characteristic of injection stretch blow molding machines, imparts superior strength, clarity, and gas-barrier properties to the finished bottle. Servo-motor-driven stretching provides precise, repeatable stroke control for every cycle, ensuring identical bottle geometry across the entire production batch.

Edible Oil and Handle Bottle

EPA.ES-2C150 Handle Bottle Blow Molding Machine Parts

Injection Unit

The injection unit consists of a precision-machined screw and barrel assembly responsible for plasticizing PET or PP resin at controlled temperatures (typically 265–280°C for PET). Servo-driven screw rotation ensures consistent melt volume and pressure during each injection cycle, directly determining preform weight accuracy and wall uniformity. Barrel heating zones are independently PID-controlled to prevent thermal degradation of resin and maintain melt flow index within specification for every bottle produced.

Molding Station

The molding station houses the 2-cavity preform mold or blowing mold depending on the process stage. Each cavity is machined from high-grade tool steel with a mirror-polished finish to minimize surface defects on finished bottles. The station's modular construction allows rapid mold changeovers, which is critical for manufacturers running multiple SKUs on the same line. Mold temperature is controlled via integrated cooling channels connected to the chiller, keeping each cavity at 8–10°C for optimal cycle times and bottle clarity.

Clamping Unit

The clamping unit provides the mechanical force required to hold mold halves securely closed against the internal blow pressure of 26–35 kg/cm². The EPA.ES-2C150 uses a servo-driven toggle clamping mechanism that delivers fast, repeatable open-close cycles while minimizing energy consumption compared to purely hydraulic systems. A clamping stroke of 190 mm and a maximum mold-open distance of 440 mm accommodate the full range of edible oil and handle bottle molds in the ES-2C series without requiring machine modification.

Blowing Unit

The blowing unit comprises a high-pressure compressor circuit, solenoid control valves, and a stretch rod actuator working in concert to execute the biaxial orientation step. Low-pressure air at 7 kg/cm² is first introduced to pre-expand the preform, followed by high-pressure air at 26–35 kg/cm² for final shaping. The stretch rod is servo-controlled with a stroke of 450 mm, providing precise biaxial orientation that is the defining quality feature of this injection stretch blow molding machine platform and is central to the bottle's wall-strength and barrier performance.

Control System

The EPA.ES-2C150 uses an industrial-grade PLC control system with a color touchscreen HMI that provides operators with real-time monitoring of all process parameters: temperature zone setpoints, blow pressure, stretching speed, cycle count, and alarm status. Recipe storage allows saving of up to 50 production programs, enabling rapid changeover between bottle models. The system also includes fault-diagnosis routines that identify and display malfunction codes, reducing troubleshooting time significantly and supporting the machine's reputation as a reliable blow molding machine for high-uptime production environments.

Preform Heating Oven

The multi-zone infrared heating oven is a core component of this automatic blow molding machine, responsible for conditioning preforms to the precise temperature profile required for effective biaxial stretching. Independent zone controllers manage each bank of infrared lamps, while forced-air cooling prevents overheating of the neck thread area. The oven capacity of 60 preform positions in the EPA.ES-2C150 ensures a continuous supply of thermally conditioned preforms to the blow station, sustaining the rated output of 1,800 bottles per hour without thermal delays or inconsistencies.

Preform Transport and Transfer System

An automated preform transport system, including a hopper loader, conveyor, and mandrel-based transfer mechanism, feeds preforms from bulk storage into the heating oven and subsequently into the blow mold station without manual handling. This fully automated preform flow eliminates contamination risks critical in food-grade packaging, and is a key reason that the EPA.ES-2C150 qualifies as a fully automatic blow molding machine. The transfer system is designed for zero-jam reliability with quick-release joints for fast maintenance access.

Bottle Ejection and Conveyor System

Upon completion of each blow-mold cycle, finished bottles are automatically ejected from the open mold cavity and transferred to an outfeed conveyor for downstream processing such as leak testing, labeling, filling, or capping. The ejection system uses pneumatic pushers synchronized with the mold-open sequence to prevent bottle deformation or scratching. The outfeed conveyor speed is adjustable to match downstream line speed, making the EPA.ES-2C150 straightforward to integrate into fully automated filling and packaging lines serving the edible oil and condiment industry.

Edible Oil and Handle Bottle Blow Molding Machine

Two-Stage Blow Molding Machine vs. Single-Stage Blow Molding Machine

Single-Stage Blow Molding Machines

Working Principle: Single-stage machines integrate preform heating and bottle blowing within a single system. PET preforms are injection-molded and immediately transferred to the blowing station while still warm, eliminating the need to cool and reheat preforms. This tight integration suits compact production operations where floor space and capital budget are constraints. These machines are a simplified version of the injection stretch blow molding machine concept, handling the full process in one pass.

EPA.ES-2C150 Plastic Blow Molding Machine Maintenance

1. Regular Infrared Lamp and Oven Inspection
Inspect all infrared heating lamps weekly for signs of dimming, cracking, or uneven radiation output. Lamps with degraded output cause non-uniform preform heating, leading to bottle defects such as uneven wall thickness and clarity loss. Replace any lamp showing more than 15% output deviation from its rated specification. Clean lamp reflectors monthly with a dry, lint-free cloth to remove resin dust accumulation, which can reduce heating efficiency and increase cycle times on this automatic blow molding machine.

2. Cooling Water Circuit Maintenance
The cooling water system must be checked bi-weekly for flow rate, temperature stability, and water quality. Maintain the system's operating temperature at 8–10°C using the connected chiller, and check flow rate against the rated 30 ltr/min for the EPA.ES-2C150. Flush the cooling circuits quarterly with a mild descaling agent to remove mineral scale that restricts flow and reduces cooling efficiency. Monitor water quality using conductivity and pH meters; deionized or softened water is strongly recommended to prevent internal corrosion and blockage of the mold cooling channels.

3. Mold Cavity and Parting Surface Care
Clean blow mold cavities at the end of each production shift using a soft brass brush and mild solvent to remove PET oligomer deposits and oil residues that accumulate on polished cavity surfaces. Inspect parting line surfaces for nicks, scratches, or wear that could cause flash on finished bottles. Apply a thin film of food-grade mold release lubricant to parting surfaces during extended shutdowns to prevent oxidation. Proper mold care directly influences the surface quality and dimensional accuracy of every bottle this fully automatic blow molding machine produces.

4. Lubrication of Mechanical Drive Components

Frequently Asked Questions

Q: What bottle sizes can the EPA.ES-2C150 fully automatic blow molding machine produce?
A: The EPA.ES-2C150 is designed to produce containers with a maximum volume of 2,500 ml per cavity, with a maximum container diameter of 130 mm and a maximum container height of 250 mm. It is particularly optimized for edible oil and handle bottles in the 1L to 5L range. For larger volumes up to 22,000 ml (20L), the EPA.J-2C366(20L) model within the same series is available. Custom mold configurations allow the machine to accommodate a wide range of intermediate bottle sizes to meet specific production requirements.

Q: What is the theoretical output of the EPA.ES-2C150 edible oil bottle blow molding machine?
A: The EPA.ES-2C150 has a rated theoretical output of 1,800 bottles per hour based on 2-cavity production with standard PET preforms and optimized process parameters. In practice, sustained output typically reaches 1,700 to 1,780 bph depending on bottle size, preform weight, cooling requirements, and ambient conditions. For higher throughput requirements, the EPA.ES-2C200 model in the same series delivers a theoretical output of 1,600 bph with larger bottle volumes up to 5,000 ml.

Q: What materials are compatible with this plastic blow molding machine?
A: The EPA.ES-2C150 is primarily designed for PET (Polyethylene Terephthalate), which is the standard material for transparent edible oil and condiment bottles. The machine can also process PP (Polypropylene) and compatible thermoplastic resins. For HDPE applications, please consult our technical team regarding machine configuration requirements. All compatible materials must meet food-contact safety standards when used for edible oil or condiment packaging. Ever-Power can advise on material selection based on the specific container application and target market.

Q: How does the EPA.ES-2C150 compare to an extrusion blow molding machine for oil bottles?
A: The EPA.ES-2C150 uses injection stretch blow molding (ISBM), which differs fundamentally from an extrusion blow molding machine. ISBM produces bottles with superior wall-thickness uniformity, better optical clarity, higher burst strength, and more precise neck-thread dimensions compared to EBM. For edible oil packaging where clarity, label adhesion, and structural integrity are critical, ISBM is the preferred technology. Extrusion blow molding is more suitable for irregular shapes and handle containers where neck precision is less critical. For large-handle oil bottles requiring excellent transparency, the EPA.ES-2C150 is the stronger solution.

Q: What cooling water requirements does the EPA.ES-2C150 blow molding machine need?
A: The machine requires cooling water at an operating pressure of 5–6 kg/cm², maintained at a temperature of 8–10°C, with a flow rate of 30 ltr/min. A dedicated industrial chiller is required to achieve and maintain the 8–10°C setpoint reliably, regardless of ambient temperature. Using softened or deionized water is strongly recommended to prevent mineral scale buildup in the mold cooling channels, which would reduce cooling efficiency and increase bottle defect rates over time. Cooling water quality should be monitored monthly for conductivity and pH levels.

Q: Is this an all electric blow molding machine or does it use hydraulic systems?
A: The EPA.ES-2C150 utilizes a hybrid architecture combining servo-electric drives for clamping, stretching, and preform transport with pneumatic systems for the blow circuit. It is not a purely all electric blow molding machine or full electric blow molding machine in the strictest sense, as it relies on compressed air for the blow stage. However, it does not use traditional hydraulic oil circuits, which reduces maintenance complexity, eliminates hydraulic oil contamination risks, and improves energy efficiency compared to older hydraulic blow molding systems. For specific servo-electric configurations, please contact our sales team.

Q: What high-pressure air supply does the EPA.ES-2C150 require?
A: The EPA.ES-2C150 requires high-pressure air at a blowing pressure of 26–35 kg/cm² (approximately 25–35 bar), with a high-pressure air consumption of 1,000–1,500 ltr/min. A dedicated high-pressure air compressor rated for at least 35 bar is required. Low-pressure control air at 7 kg/cm² with consumption of 600 ltr/min is also needed for pneumatic actuators and pre-blowing circuits. Ever-Power recommends sourcing matched compressor and air dryer systems from our auxiliary machinery portfolio to ensure air supply compatibility and reliability for continuous production operations.

Q: How long does it take to change molds on the EPA.ES-2C150?
A: With trained operators following the standardized mold changeover procedure, mold changes on the EPA.ES-2C150 typically take 2 to 4 hours depending on the difference in bottle dimensions between the outgoing and incoming molds. Quick-release clamping fixtures and a modular blow mold design reduce mechanical changeover time significantly. After mold change, a short warm-up and parameter verification period of 30–60 minutes is required before full-speed production resumes. Ever-Power provides detailed mold changeover procedure documentation and offers remote support during the first changeover for new customers.

Q: What is the power supply requirement for the EPA.ES-2C150 blow molding machine?
A: The EPA.ES-2C150 requires a maximum heating power supply of 42.5 kW, with typical working heating power of 18 kW during steady-state production. The machine operates on a three-phase industrial power supply. The exact voltage and frequency specification (e.g., 380V/50Hz or 440V/60Hz) should be confirmed at the time of order placement to ensure compatibility with the buyer's local electrical infrastructure. A dedicated electrical panel with appropriate circuit breakers and safety disconnects must be installed by a licensed electrician prior to machine commissioning.

Q: Does Ever-Power provide custom blow molding machine configurations for non-standard bottle shapes?
A: Yes. Ever-Power offers fully customized blow molding machine and mold solutions for non-standard bottle geometries including asymmetric shapes, multi-handle designs, ergonomic grip profiles, and embossed branding elements. Our engineering team works with clients' packaging designers using 3D CAD software and flow simulation tools to develop mold designs that are manufacturable within the EPA.ES-2C150's clamping and blow station geometry. Custom mold development typically requires 6–10 weeks from design approval to first sample production. Please provide your bottle drawing or sample for a technical feasibility assessment.

Edible Oil and Handle Bottle Blow Molding Machine

Customer Reviews

Carlos Mendez, Edible Oil Industry, Brazil
"We installed the EPA.ES-2C150 about eight months ago at our edible oil bottling plant in Sao Paulo, and honestly the throughput has been rock solid. We are running 5-liter sunflower oil bottles and averaging around 1,750 to 1,780 bottles per hour consistently across our two daily shifts. The centralized heating design was something our engineering team was a bit skeptical about at first, but it has proven to be genuinely energy-efficient. Our electricity consumption per thousand bottles is down about 12% compared to our previous machine. The Ever-Power service team was also very professional during installation and stayed on-site for four days until we were comfortable with the system. Really satisfied with this purchase."

Li Weiming, Condiment Packaging, China
"I was looking for a reliable handle bottle blow molding machine for soy sauce containers between 2L and 5L for our factory in Shandong. We compared three different suppliers and ended up choosing Ever-Power mainly because of their technical support reputation and the fact that spare parts are readily available. The machine has been running for six months now without a single unplanned stoppage. Wall thickness consistency is very good, our QC rejection rate is under 0.5%, which is much better than our old equipment. Delivery was fast, arrived exactly on the schedule they quoted us."

Rajesh Patel, Food Packaging, India
"Very good experience with the procurement and logistics team at Ever-Power. We ordered the EPA.ES-2C150 from our facility in Gujarat to produce 3-liter PET edible oil bottles with rear handles. Shipping from Mexico to Nhava Sheva port was smooth and the customs documentation was complete and accurate, which saved us a lot of hassle. The machine itself was easy to install with the provided manual and the remote video support from their engineers. We have been running it for four months and it is performing above our expectations. The bottle transparency is excellent and our retail customers have noticed the quality improvement. We plan to order a second unit in the next quarter."

Hendra Sutanto, Lubricant Packaging, Indonesia
"We've been operating the EPA.ES-2C150 for nearly a year at our motor oil bottle production line in Karawang, West Java. We produce 4-liter and 5-liter HDPE handle bottles for automotive lubricant brands and the machine handles the material well. One thing I particularly appreciate is the PLC control system, the recipe storage feature means our operators can switch between bottle programs quickly without re-entering all the parameters manually every time. This has cut our changeover time by almost 40 minutes per shift, which adds up to significant additional production capacity over the month. After-sales support through WhatsApp has been surprisingly responsive too."

Sofia Ramirez, PET Bottle Production, Mexico
"The after-sales service from Ever-Power has been the best part of this experience. We run a small PET bottle production company in Mexico City and this was our first fully automatic blow molding machine purchase. When we had a question about setting the stretch rod speed for a new 2.5-liter bottle mold, their technical team got back to us within two hours and walked us through the PLC settings step by step on a video call. The machine itself has been reliable for the seven months since installation and our customers have commented positively on the improved clarity and consistency of the bottles. For small to mid-size bottlers in Mexico looking for a trustworthy supplier, Ever-Power is worth considering seriously."

Ahmed Hassan, Edible Oil Packaging, Egypt
"I will be honest, we initially had concerns about sourcing a blow molding machine from Mexico for our factory in Cairo. But we did our research carefully and the technical specifications and price of the EPA.ES-2C150 were very competitive. The machine arrived well-packaged with no damage. We produce 2-liter and 5-liter edible oil bottles and the output quality has been consistent from day one. The cooling water control system keeps temperature very stable at around 9 degrees Celsius which is important in our climate where ambient temperatures get quite high in summer. No issues with overheating or bottle deformation. I would recommend this machine to any Egyptian bottler looking to upgrade."

Mustafa Yildirim, Condiment Packaging, Turkey
"We are a mid-scale condiment manufacturer in Istanbul and we ordered the EPA.ES-2C150 for our vinegar and olive oil bottle production. The machine has been running three shifts daily for five months and we have not had any major mechanical issues at all. The output of 1,800 bottles per hour means we were able to reduce our production shifts from four to three while maintaining the same volume, which has saved us labor cost. The blow mold we ordered together with the machine was well-made and the bottles have very clean parting lines with no flash issues. Packaging and shipping to Turkey was professional and the insurance documentation was all in order."

Thabo Dlamini, Cleaning Products Packaging, South Africa
"We use the EPA.ES-2C150 to produce large 10-liter front-handle PET bottles for a household cleaning detergent brand here in Johannesburg. The machine has proven to be robust enough for our production environment where humidity and ambient temperature vary quite a bit seasonally. The cooling system has performed reliably in all conditions. What I appreciate most is that the machine does not require a highly skilled operator once it has been set up correctly. Our team picked up the operation quickly after the initial training video call with Ever-Power. Replacement parts like lamps and air valves are also reasonably priced. Very good value for the investment."

Nguyen Thi Lan, PET Bottle Production, Vietnam
"Our company in Ho Chi Minh City bought the EPA.ES-2C150 nine months ago to produce 2-liter and 3-liter PET edible oil bottles. Honestly the quality of the bottles is very good, our retail clients have noticed the improvement in clarity and uniformity compared to what we were producing before. The machine runs smoothly and the PLC interface is easy to understand even for our operators who are not very technical. The one thing I would mention is that the technical manual could be more detailed in the Vietnamese language, but the English version is clear enough and the video call support from the Ever-Power team is always helpful. Overall I am very happy with the decision to choose this supplier."
