Introduktion till enstegs formsprutning med sträckblåsning
Upgrading your manufacturing capacity shouldn’t require abandoning your existing tooling investments. The one-step injection stretch blow molding process is a highly efficient plastic container forming technology widely used for high-precision, demanding hollow products. From baby bottles and water cups to pharmaceutical containers and cosmetics packaging, this process handles materials like PET, PETG, PP, PC, Tritan, PS, ABS, and PLA with ease.
Kärnegenskapen hos detta enstegs formsprutningssträckformningsmaskin is that the three primary steps—injection, stretching, and blow molding—are completed continuously within a single piece of equipment. By eliminating intermediate handling and reheating steps, manufacturers experience a massive boost in production efficiency and product consistency.
Standard Process Flow
- Injektion: Raw plastic is melted and injected to form the preform.
- Preform Tail Cutting / Heat Preservation: The preform temperature is conditioned for ideal stretching.
- Sträckformblåsning: Förformen sträcks axiellt och blåses radiellt.
- Flaskavhämtning: The finished product is cleanly ejected.
Core Advantages of the EPY150-V4
- Hög effektivitet och energibesparing: Bypasses secondary preform reheating by utilizing residual injection heat, reducing energy consumption by approximately 40%.
- Överlägsen prestanda: Biaxial molecular orientation drastically improves the container’s compression resistance, gas barrier, and clarity.
- Hög precision och dimensionsstabilitet: Fully automated control minimizes human error, perfect for large-scale, continuous production runs.
- Maximum ROI: Features low energy use, reduced labor needs, a compact footprint, and competitive pricing with robust stability.

Utrustningskomposition och nyckelteknologier
The equipment consists of five major integrated systems. Here is how our engineering guarantees flawless production:
1. Precisionsinjektionssystem
The injection unit utilizes a high-precision servo-driven mechanism equipped with our proprietary, patented screw and barrel design to ensure incredibly uniform plasticization of the melt.
Ever Power’s Patented High-Efficiency Screw Design
- Högprecisionstemperaturkontrollsystem (noggrannhet inom ±1 ℃).
- Servodriven injektionsenhet för snabb respons och ultimat repetitionsnoggrannhet.
- Advanced preform wall thickness control (axial and radial optimization).
2. Intelligent värmesystem
Using zoned heating rings or advanced water/oil temperature control, the system features non-contact temperature measurement to avoid preform surface damage. It automatically adapts heating power based on real-time production speeds.
3. Sträckblåssystem
Comprising stretch rods, blow cores, and high-pressure air valves, this system executes rapid axial and radial expansion. Stretching speeds reach up to 400mm/s with a position accuracy of ±0.1mm. Our independent pressure regulating system keeps air fluctuations strictly within ±0.05MPa.
4. Advanced Mold System
The EPY150-V4 utilizes a rotating multi-station structure. We offer both 3-station and 4-station configurations depending on material requirements. The 3-station is standard for straightforward shapes, while the 4-station incorporates an extra conditioning step for complex resins like thick-walled PETG.
3-stationslayout: Injektion, formblåsning, utstötning.
4-stationslayout: Injection, Conditioning/Tail Cut, Blow Molding, Ejection.
Our high-precision mold processing ensures cavity surface roughness of Ra≤0.8μm. Optimized cooling channels slash cooling times by 30%, and rapid tooling technology allows mold changes in under 60 minutes. Proper wiring is crucial for these complex molds:
We also design and manufacture premium custom molds in-house.
5. Centraliserat styrsystem
An independent, multi-axis motion controller synchronizes all stations perfectly. Adaptive process parameters adjust in real-time based on production data, backed by a remote diagnostic system to maximize uptime.
Materialtillämpningar och produkttyper
The EPY150-V4 excels as a versatile solution, particularly acting as the ideal Enstegsblåsningsutrustning för kosmetiska förpackningar, pharmaceuticals, and food/beverage applications. Supported materials include:
- SÄLLSKAPSDJUR: High transparency and barrier properties, perfect for beverage bottles and food jars.
- PP: Excellent high-temperature resistance (>120℃) for hot-fill juice and tea containers.
- PETG: Superior toughness, colorability, and chemical resistance. Ideal for thick-walled cosmetic jars, mascara, and lip gloss packaging without stress whitening.
- Dator: High strength and heat resistance for infant feeding bottles and sports cups.
This machine efficiently produces round or asymmetrical containers ranging from 5ml up to 20L.
The Critical Role of Matched Air Compressors
A high-quality enstegsblåsningsmaskin cannot operate effectively without an equally capable air supply. The stretch blow molding phase requires significant volumes of high-pressure air to force the preform against the mold walls rapidly and accurately.
Ever Power provides customized, matched oil-free screw air compressors. In pharmaceutical and food applications, 100% oil-free air is a strict regulatory requirement to prevent internal container contamination. Furthermore, our matched compressors guarantee absolute pressure stability. Even minor pressure drops can result in uneven bottle wall thickness, improper thread formation, or incomplete bottom shapes. Investing in our integrated air system ensures your ISBM machine operates at peak capacity with zero defect rates.

Vanliga frågor (FAQ)
1. Do I need to modify my Japanese ASB-12M molds to fit the EPY150-V4?
No modifications are required. Our machine is specifically engineered with matching platen dimensions, tie-bar spacing, and stroke lengths to accept ASB-12M molds natively. It is a true plug-and-play upgrade.
2. How much energy can I expect to save compared to older hydraulic models?
Customers typically report energy savings of around 40%. This is achieved by the direct heat utilization of the one-step process and the high-efficiency servo motors that only consume power during active movements, unlike constantly running hydraulic pumps.
3. Can this machine process challenging materials like Tritan or heavy-wall PETG?
Absolutely. By selecting the 4-station configuration and utilizing our specialized screw profiles, the machine provides the precise temperature conditioning required to process complex resins without defects like stress whitening or burn marks.
4. What is the typical lead time for delivery and installation?
Standard machine delivery is generally 45 to 60 days. If custom molds are ordered simultaneously, an additional 15-20 days are needed for rigorous testing. Our global engineering team will then travel to your site to ensure a swift setup.
5. Are spare parts difficult to source internationally?
Not at all. We utilize globally recognized components for critical systems (e.g., servo drives, PLCs, pneumatic valves). Standard parts can be sourced locally in most countries, and proprietary parts are dispatched immediately via international express shipping from our factory.
