1. Product Overview
Applicable Industries: Edible oil refineries, bulk condiment manufacturers, and large volume liquid chemical packaging.
Core Advantages Summary: Producing large-capacity 5L to 20L containers presents immense thermal and structural challenges. EVER POWER, originating from the Netherlands, engineers heavy-duty two-stage blow molding machines specifically for this sector. Utilizing centralized heating to penetrate thick preforms and specialized molds for automatic handle integration, we ensure your bulk containers are structurally bulletproof and highly transparent.

| Handle Integration | Molds configured for Front & Rear insertion |
| Clamping Force | Heavy-Duty Double Crank |
3. Working Principle & Structure
Thick 5L preforms cannot be heated standardly; the surface will burn before the core melts. EVER POWER employs a “Centralized Heating” method. Preforms are bunched extremely close together through intense infrared tunnels to absorb maximum energy deeply. Upon exiting, a variable-pitch track spaces them wide apart (“Distance Blowing”) to fit the massive 5L-20L molds. Inside the mold, operators or robotics insert plastic handles just before the high-pressure air inflates the hot PET around the handle locking it permanently in place.
4. Core Advantages
⚡ Energy Saving Heating
Centralized heating arrays reduce electrical waste by up to 35% compared to standard wide-pitch ovens.
🦾 Extreme Clamping Force
Heavy-duty toggles ensure the molds stay shut under the massive pressure needed to blow thick 5L walls.
🛠️ Handle Integration
Custom mold architecture allows for seamless molding around front or rear plastic carry handles.
📦 Warehouse Savior
Blowing massive 20L containers on-demand eliminates the disastrous cost of storing empty pallets of large jugs.
📉 Scrap Elimination
Biaxial stretching prevents the base drop-outs common in thick extrusion-blown containers.

5. Structure & Material Technology
Blowing 20L jugs requires a machine base of extraordinary mass. EVER POWER utilizes ultra-thick alloy steel to prevent chassis flexing. Because large containers cool slower, we exclusively use premium aviation aluminum for the blow molds. The rapid thermal transfer of aluminum allows the thick PET to crystallize faster, speeding up the overall cycle time significantly.
6. Typical Applications
Bulk Edible Oils & Sauces
Producing 5L and 10L handle-integrated jugs capable of severe stacking pressure without bulging.
20L Water Dispensers
Replacing heavy, expensive Polycarbonate (PC) water cooler jugs with durable, lightweight PET.
7. Selection Guide
Do not under-spec your air compressors for large containers. Blowing 5L to 20L requires massive volumetric airflow at high pressure. EVER POWER provides turnkey auxiliary packages. Ensure you discuss your exact handle geometries with our engineers so we can machine the mold clearance perfectly.

10. Case Studies: Global Field Notes
11. Frequently Asked Questions
Does the handle require a special mold?
Yes, our aluminum molds are CNC-machined with a specific cavity. The plastic handle is inserted, and the blowing PET expands around it to lock it firmly in place.
Is a 20L PET bottle strong enough to stack?
Absolutely. The biaxial stretching inherent in our process aligns the polymer chains, granting the 20L jug immense vertical top-load strength for palletizing.
