1. Produktöversikt
Tillämpliga branscher: Stackable edible oil jugs, CSD carbonated bottles, and lightweight mass mineral water.
Sammanfattning av kärnfördelar: The core reason PET replaced glass and heavy plastics is a scientific phenomenon called “biaxial orientation.” EVER POWER, a high-end manufacturer hailing from the Netherlands, builds two-stage stretch blow molding machines that perfect this process. By orchestrating a flawless mechanical vertical stretch simultaneously with a high-pressure radial blow, our machines yield bottles with extreme top-load strength while using drastically less raw resin.

3. The Science of Biaxial Stretching
Think of PET plastic like a net of messy fibers. When heated in our infrared ovens, it softens. Once in the mold, the servo stretch rod pushes the preform down (the “axial” stretch). A fraction of a second later, 35-bar high-pressure air explodes into the preform, pushing it sideways against the mold (the “hoop” or radial stretch). This “biaxial” pull aligns all the polymer chains perfectly into a tight cross-hatch matrix. This strain crystallization process makes the plastic exponentially stronger, clearer, and less permeable to gases than its unstretched state.
4. Top 5 Advantages of Flawless Biaxial Orientation
📦 Massive Top-Load Strength
Aligned polymers mean you can stack 5L edible oil jugs on pallets without the bottom layers buckling under the weight.
📉 Drastic Lightweighting
Because the plastic becomes stronger, you can significantly reduce the preform weight, saving hundreds of thousands in raw material costs.
🫧 Gas Barrier Properties
Biaxial orientation tightens the plastic structure, preventing carbonation from escaping CSD bottles and extending shelf life.
💎 Diamond Clarity
Stretching the molecules eliminates cloudiness, yielding a perfectly transparent bottle that looks like premium glass.
💧 Drop Test Survival
The cross-linked polymer matrix flexes instead of shattering, making it ideal for shipping heavy liquid chemicals and detergents.

5. Struktur- och materialteknik
Executing the perfect biaxial stretch requires split-second timing. EVER POWER equips its machinery with high-response pneumatic valving. This ensures the 35-bar blow hits exactly at the bottom of the servo rod’s stroke. We lock this shape in instantly using CNC-machined aviation aluminum molds equipped with dense water-chilling channels, freezing the aligned polymer matrix before it can relax.
6. Typical Applications Demanding Biaxial Strength
Carbonated Soft Drinks (CSD)
Without biaxial stretching, the internal gas pressure of soda would balloon the bottle. Stretching fortifies the petaloid base to withstand this stress.
Bulk Edible Oil (5L-20L)
Heavy liquids require massive top-load stackability. Biaxial orientation prevents the lower pallet layers from buckling.
7. Urvalsguide
Always verify your supplier’s clamping force capabilities. If the machine cannot hold the mold tightly closed during the 35-bar radial stretch, the parting lines will blow out, ruining the structural integrity. EVER POWER utilizes heavy-duty double crank toggles to guarantee the mold remains hermetically sealed.

11. Vanliga frågor
What is the minimum pressure required?
To achieve proper radial stretching, your auxiliary compressor must supply between 30 to 35 bar (3.0 to 3.5 MPa) of high-pressure air consistently.
