Heavy-Duty 400KN Clamping Force for PC 5-Gallon & Large PET Edible Oil Containers
Overview: The Titan of the Industry – EPY650-V4
In the specialized sector of large-format container manufacturing, stability and clamping power are the defining metrics of quality. Drawing on 20 years of expertise in heavy industrial machinery, I introduce the EPY650-V4. This is not just a machine; it is a 28-ton manufacturing fortress designed to produce large-volume containers (up to 20 Liters) with the precision typically reserved for small pharmaceutical vials.
The EPY650-V4 stands alone in its class with a massive 400KN Injection Clamping Force and an equally impressive 400KN Blowing Clamping Force. Unlike standard ISBM Machine models, this unit features an extended upper mold stroke of 1070mm, specifically engineered to accommodate deep-draw products like 5-gallon PC water cooler bottles, large PET edible oil jerrycans, and industrial wide-mouth jars.
Powered by a 75KW Inovance/WEICHI Servo System and a high-capacity 15KW Nano-infrared heating unit, the EPY650-V4 manages the immense thermal mass of heavy preforms (up to 480g shot size) with ease. For manufacturers targeting the large container market, this One Step PET Bottle Machine offers a seamless, flash-free, and energy-efficient solution that traditional two-step systems simply cannot match for this size category.

4-Station Process for Heavy Wall Containers
Processing large, heavy preforms (up to 900g) requires meticulous thermal management. The EPY650-V4's 4-station design ensures the thick preform walls are perfectly conditioned before stretching.
1. Injection
Massive injection. 400KN clamping prevents flash on thick preforms. Handles high-viscosity PC/PET.
2. Conditioning
CRITICAL: Deep core conditioning. Equalizes temperature in thick 900g preforms to prevent haze and crystallinity.
3. Stretch Blow
Long-stroke stretching. The 1070mm stroke allows for deep containers like 5-Gallon water bottles.
4. Ejection
Heavy-duty ejection mechanism designed to handle the weight of large 20L bottles.
Large Format Analysis: One-Step vs. Two-Step
| Feature | Ever-power EPY650-V4 (ISBM) | Two-Step Process |
|---|---|---|
| Preform Heating | Utilizes Injection Heat (Efficient) | Reheating Thick Preforms is Slow & uneven |
| Bottle Quality | Crystal Clear (No Scuffs) | Scuffs common during heavy preform transport |
| Energy Consumption | Lower (No Reheat Oven) | Very High (Heating thick walls takes massive energy) |
| Neck Precision | High Tolerance (Molded) | Neck deformation risk in oven |
| Material Versatility | Excellent (PC, Tritan, PETG) | Limited (Mostly PET) |
Industry Applications for Large Containers
5-Gallon Water Bottles (PC/PET)
The definitive machine for producing durable, reusable 20L water cooler bottles. The Injection Blow Molding Machine (One Step) process ensures the neck strength required for heavy lifting.
Edible Oil Jerrycans
Produces 5L to 20L PET edible oil containers with integrated handles. The 400KN force guarantees seal integrity for these heavy liquids.
Large Industrial Jars
Ideal for wide-mouth jars used in food service (pickles, mayonnaise) or industrial storage. The wide platens accommodate large neck diameters up to 140mm.
[Middle East] Large Water Bottle Production Strategy
In the Middle East, the demand for 5-Gallon water bottles is immense. Traditional extrusion blow molding yields bottles with poor clarity and seams. The EPY650-V4 offers a seamless, crystal-clear PC/PET solution. Equipped with an Oversized Oil Cooling System, it maintains the 400KN pressure required for large surface area molds even in 50°C factory environments.
[USA] Industrial Container Safety Compliance
Our machine complies with strict safety standards for large machinery. The 28-ton structure absorbs the immense kinetic energy of moving large molds, ensuring operator safety and machine longevity.
Competitor Benchmarking: Ever-power vs ASB-650EXHS
We offer a robust alternative for heavy-duty molding:
- Clamping Force: 400KN (Injection & Blowing) - Matches or exceeds top-tier Japanese specs.
- Open Architecture: We use Inovance PLCs, allowing for easier local maintenance compared to proprietary "Black Box" systems.
- Cost Efficiency: Achieve the same 20L production capability at 50% of the CAPEX.
