Inside Bancy’s Factory

Where Quality is Engineered

From 100% Virgin Material to Double-Layer Welding. See the precision behind every flexible tank we ship globally.

Why Our Tanks Don’t Leak: The Double-Layer Tech

We apply an extra reinforcement strip over high-stress seams.

This ‘Double-Layer’ technology creates a mechanical bond stronger than the fabric itself, reducing failure risk by 99% compared to standard single-welds.

Flexible Tank Manufacturer Process: Transparent & Flawless

Material Screening
A Standard for Top Flexible Tank Manufacturer

Quality inspector measuring PVC fabric thickness with digital caliper

Quality starts before production. We use digital calipers to verify thickness and tensile testers to ensure fabric strength. Standard: Material thickness tolerance controlled within ±0.05mm.

01

Automated CNC Cutting

Automated CNC cutting table slicing flexible tank fabric material

Computer-controlled cutting tables translate your dimensions into reality with millimeter-level accuracy. This eliminates manual errors and guarantees perfect geometry for the subsequent welding stage.

02

Reinforced Seam Fusion

Heat sealing machine creating reinforced seams on grey PVC material

This is where Bancy stands out. For the main tank body, we apply an extra reinforcement strip over the seams using advanced heat sealing. This creates a mechanical bond stronger than the fabric itself, withstanding high internal pressure.

03

Welding & Assembly

High frequency welding machine installing valves on flexible tank

Valves and flanges are installed using our specialized heavy-duty welding process. This molecular-level fusion ensures that connection points—traditionally the weakest spots in flexible tanks—become as robust as the tank body itself.

04

Rigorous QC & Inspection

Quality is monitored at every stage. We conduct 100% Visual Inspection on all seams and perform Systematic Air-Tightness Sampling to ensure compliance with our leak-prevention standards.

05

Export Packaging

Forklift moving wooden crates containing flexible tanks for export

Products are carefully folded to minimize volume (High Cube Efficiency). Wrapped in woven bags or fumigation-free wooden crates, ready for secure global logistics and easy resale.

06

International Safety Standards (CE Compliant)

At Bancy, quality isn’t just a certificate—it’s a daily discipline.

While we operate under a strict Internal Quality Management System (QMS), our flexible tanks are manufactured in full compliance with CE Certification safety and environmental standards.

We don’t rely on guesswork. From the ±0.05mm raw material tolerance to our rigorous systematic air-tightness testing, every step is data-driven to ensure your tank withstands the harshest conditions.
