400KN Clamping Force | Up to 20L Capacity | 4-Station Rotary Precision

The EPY650-V4 is the heavy industrial leader of the EPY series. Weighing in at 28 Tons and boasting a 400KN clamping force, it is engineered for the massive production of large-volume containers, such as 5-gallon PC water barrels, 20L edible oil containers, and wide-mouth jars.

Machine Capabilities

The EPY650-V4 integrated blow molding machine is designed to handle the toughest molding challenges. Its massive platens and extended stroke (1070mm upper / 550mm lower) allow for deep-draw containers that smaller machines simply cannot produce.

Whether you need to produce a single 20L PC water barrel or four 5L PET oil bottles per cycle, the EPY650-V4 delivers consistent wall thickness and high optical clarity, free from the hazing often seen in two-step processes.

💪 Heavy-Duty Specifications:

  • Injection Clamping: 400 KN
  • Blowing Clamping: 400 KN
  • Shot Size: Up to 480g (Theoretical)
  • Max Bottle Size: 20 Liters (280mm Diameter)

How It Works: The 4-Station ISBM Principle

The EPY650-V4 utilizes a 4-station rotary table system that rotates 90 degrees every cycle. This integrates the entire production line into one compact unit, ensuring energy efficiency and superior bottle quality.

1. Injection Station

Molten plastic (PET/PC/PP) is injected into a cooled mold to form the preform. The neck finish is molded to exact tolerances here, ensuring a leak-proof seal for the final cap.

2. Conditioning Station

The hot preform is transferred here for temperature equalization. Heating pots or cooling rods adjust the preform's thermal profile, which is critical for blowing uniform walls in square or oval containers.

3. Stretch-Blow Station

The conditioned preform is stretched axially by a rod and expanded radially by high-pressure air (up to 3.5 MPa). This biaxial orientation significantly increases the bottle's strength and clarity.

4. Ejection Station

The finished bottle cools and is automatically ejected onto a conveyor. Since the bottle never touches the floor or manual handling during forming, it remains pristine and scratch-free.

Engineered for Performance

Triple-Servo Power

The EPY650-V4 is powered by 3 sets of servo pump systems totaling 75.7KW of motor power. This hybrid drive provides the immense force needed for large platens while maintaining the energy efficiency of a servo machine.

Nano-Infrared Heating

A massive 15KW Nano-far-infrared heating ring ensures the screw plasticizes large volumes of material rapidly and uniformly. This is critical for maintaining cycle speeds when producing heavy 20L containers.

Global Component Sourcing

We utilize only the best: Inovance/MIRLE PLC for control, Parker (USA) for pneumatic stability, and YUKEN (Taiwan) for hydraulic precision. This ensures 24/7 reliability in demanding industrial environments.

Air Supply for 20L Containers

Blowing a 20-liter container requires a massive volume of air delivered instantly. Stability is key—any pressure fluctuation results in thin walls or blown-out bottoms.

Ever-Power supplies matched High-Volume Oil-Free Screw Air Compressors designed for large-format molding. These compressors ensure that the large volume of air needed (at 2.0-3.5 MPa) is delivered cleanly and consistently, ensuring your large containers are safe for food and water storage.

What Our Clients Say

★★★★★

"The EPY650-V4 has revolutionized our 5-gallon water bottle production. The one-step process gives us a crystal-clear finish that our old machines couldn't match, and the scrap rate is virtually zero."

- Production Manager, Major Water Bottling Plant (Middle East)
★★★★★

"We needed a machine capable of producing heavy, wide-mouth jars for food service. The 400KN clamping force on the EPY650 is incredible—it holds the mold perfectly shut even with 4 cavities running."

- Technical Director, Industrial Container Manufacturer (South America)

Frequently Asked Questions

1. Can this machine produce 5-gallon PC water bottles?

Yes. The EPY650-V4 is specifically designed for large containers. In a 2-cavity configuration, it can produce 20L (approx. 5 gallon) bottles with ease.

2. What is the advantage of one-step molding for large bottles?

Two-step processes for large bottles often result in hazing or scratches on the preforms due to handling. The one-step process eliminates preform handling, resulting in a blemish-free, high-gloss surface that is superior for premium water and oil brands.

3. What is the total power consumption?

The installed power is 90.7 KW. However, thanks to the triple-servo pump system, the machine only consumes significant power during active movements. The holding phase consumes very little energy compared to hydraulic machines.

4. How heavy is the machine?

The machine weighs 28 Tons. This extreme weight provides the necessary rigidity to prevent platen deflection under the 400KN clamping load.

5. Do you provide the molds for 20L bottles?

Yes. We design and manufacture large-format molds in-house. We can optimize the preform design to ensure the best wall thickness distribution for your specific bottle shape.
