The premium water market demands packaging that is as pure and flawless as the product inside. Whether producing high-end still water or pressurized sparkling water, the bottles must exhibit exceptional glass-like clarity, high structural integrity, and perfect dimensional stability to hold carbonation securely. Ever Power’s advanced single stage injection stretch blow molding machine technology provides beverage manufacturers with the ultimate solution. By integrating the entire forming process into a single, highly efficient cycle, we deliver pristine bottles that elevate your brand while significantly reducing your production footprint and energy costs.
The Power of One-Step ISBM Technology
One-step injection stretch blow molding (ISBM) is the pinnacle of plastic container forming efficiency. It is the preferred method for manufacturing high-precision hollow products like premium beverage bottles, cosmetics, and medical containers from materials including PET, PETG, PP, PC, and Tritan. The defining advantage is that the three core stages—Injection, Stretching, and Blow Molding—are completed sequentially within one integrated machine. This eliminates the need to cool, eject, store, and reheat preforms, resulting in zero surface scratching and massive energy savings.
The Streamlined Process Flow
Molten PET is injected to form the preform. This ensures exact neck dimensions critical for retaining carbonation in sparkling water.
The preform’s internal latent heat is perfectly equalized, conditioning the plastic for optimal, uniform stretching.
Biaxial stretching orients the polymer molecules, giving the water bottle its high compressive strength and glass-like clarity.
The finished, pristine water bottle is automatically ejected onto a conveyor, ready for high-speed filling lines.
Core Advantages for Premium Beverage Brands
- Unmatched Optical Clarity: Because preforms are not tumbled in hoppers or reheated, there are zero surface scratches. The bottles look as clear as premium glass.
- High Structural Strength: Perfect biaxial orientation enhances the bottle’s pressure resistance, essential for safely containing highly carbonated sparkling water.
- Massive Energy Savings: Skipping the secondary preform reheating stage typical in two-step processes reduces total energy consumption by approximately 40%.
- Exceptional ROI: This mesin pengacuan tamparan satu langkah berkelajuan tinggi provides high material utilization with virtually zero scrap, all within a highly compact footprint.

Deep Dive: Equipment Composition and Key Technologies
Crafting perfect high-end water bottles requires absolute synchronization across five core mechanical systems.
1. Injection System
Using a high-precision servo-driven injection unit, this system guarantees uniform plastic melt. A major differentiator is our patented injection screw design. It is strictly engineered to melt PET uniformly without sheer stress, preventing any bubbles or yellowing that would ruin the water bottle’s appearance.
Patented Injection Screw Design for Optimal Clarity
- High-precision temperature control system (accuracy ±1℃).
- Servo-driven unit for rapid, highly repeatable injections essential for heavy sparkling water preforms.
- Preform wall thickness control system utilizes precise axial/radial adjustments.
2. Heating System
Proper thermal conditioning is critical to avoid uneven wall thickness during the high-pressure blowing phase.
- Zoned heating control allows precise temperature profiling across complex bottle designs.
- Non-contact temperature measurement prevents any surface marring.
- Adaptive heating power automatically self-optimizes based on the live production speed.
3. Stretch Blow System
- Advanced stretch mechanism operates up to 400mm/s with a positional accuracy of ±0.1mm.
- Independent high-pressure regulating valves keep pressure fluctuations under ±0.05MPa.
- Synchronous control technology ensures perfect timing between stretch and blow phases for maximum strength.
4. Mold System
Our robust rotary multi-station structures are tailored for the beverage industry. We offer flexible configurations based on your production goals.
3-Station Mold Structure
Combines Injection, Stretch Blow, and Ejection. Best for standard, high-speed still water bottle output.
4-Station Mold Structure
Includes an extra thermal conditioning station. Essential for very thick-walled preforms used in carbonated sparkling water bottles.
- High-precision machining ensures a cavity surface roughness of Ra≤0.8μm.
- Optimized cooling channels reduce cycle cooling time by up to 30%.
- Rapid mold change technology enables complete changeovers in ≤60 minutes.

Material Applications & Beverage Output
Our technology flawlessly processes the highest quality thermoplastic materials required for premium beverages:
- PET (Polyethylene Terephthalate): The undisputed champion for still and sparkling water. It offers glass-like transparency, incredible burst pressure strength for carbonation, and excellent recyclability.
- PP (Polypropylene): Used for hot-fill teas, juices, or specialized hot-water bottles due to its high heat tolerance (over 120℃).
- PETG: Applied in premium, thick-walled cosmetic jars or specialized high-impact containers.
- PC (Polycarbonate): Used for rigid, highly durable, and reusable water cooler jugs and sports cups.
Crucial Integration: Food-Grade Oil-Free Air Compressors
In beverage packaging, particularly for clear water, perfection is non-negotiable. A critical, yet often overlooked component of the ISBM line is the blowing air compressor.
During the stretch blow molding phase, massive volumes of high-pressure air are blasted directly into the heated preform, intimately contacting the interior surface of the water bottle. If a standard industrial compressor is utilized, there is a severe risk of microscopic oil vapors, moisture, or dust contaminating the air stream. This contamination will cloud the PET, ruining its optical clarity, and severely violate food safety standards.
Furthermore, maintaining the precise wall thickness required to hold high carbonation pressures requires absolutely stable air pressure. Ever Power completely mitigates these risks by offering matched 100% oil-free screw air compressors seamlessly integrated with our molding systems. These compressors guarantee a sterile, dry, and perfectly consistent high-pressure air supply. By sourcing your complete system from Ever Power, you ensure FDA-grade hygiene, pristine bottle aesthetics, and the exact dimensional precision needed for your premium water brand.

Soalan Lazim (FAQ)
1. Why is a one-step machine better for bottle clarity?
In traditional two-step processes, preforms are ejected, stored in bins, and tumbled through hoppers, causing microscopic surface scratches. Our one-step process handles the preform exclusively by the neck inside the machine, resulting in completely scratch-free, glass-like clarity.
2. Can this equipment produce thick-walled PET bottles for sparkling water?
Absolutely. For thick-walled sparkling water bottles that require high burst pressure resistance, we utilize our 4-station machine configuration. The extra thermal conditioning station perfectly equalizes the thick preform’s temperature, ensuring robust strength and preventing stress whitening.
3. What is the typical cycle time for a standard 500ml still water bottle?
Depending on the exact PET gram weight and the number of mold cavities, cycle times for a 500ml bottle generally range between 15 to 22 seconds. Our optimized water cooling channels are designed to maximize this output speed.
4. How complicated is the maintenance for the patented injection screw?
We design our equipment as a one step blow molding machine with low maintenance cost. The screw is highly durable. Routine maintenance is straightforward and primarily involves standard purging when changing resins or colors, guided by our diagnostic control system.
5. How fast can we switch production to a different bottle size?
Our machines feature rapid mold change technology. A trained operational team can completely swap out the injection preform mold and the blow mold, and load new operational parameters, in 60 minutes or less.
