27.12 MHz High-Frequency Welding: The Core of Extreme Waterproof Durability

At Sealock, we don't just "glue" materials together; we molecularly fuse them. Our Ho Chi Minh City Phase II facility utilizes advanced 27.12 MHz High-Frequency (HF) Welding technology. This process creates a bond that is often stronger than the base material itself, ensuring your gear remains 100% submersible and airtight.

How 27.12 MHz HF Welding Works

Unlike conventional heat sealing which applies heat from the outside in, HF welding uses an electromagnetic field to agitate the molecules of PFAS-Free TPU or PVC fabrics from within.

• Molecular Friction: The 27.12 MHz frequency causes rapid molecular vibration, generating internal heat.
• Fusion under Pressure: While the material is in a molten state, high-precision pneumatic presses fuse the layers into a single, seamless piece.
• Instant Cooling: The weld is cooled under pressure, "locking" the molecular structure for maximum shear strength.

Why 27.12 MHz? The Sealock Advantage

1. Uniform Energy Distribution: This specific frequency ensures deep, consistent penetration even in heavy-duty 840D High-Tenacity TPU fabrics.
2. Zero Material Degradation: By heating only the contact area, we preserve the integrity of the surrounding fabric and its waterproof coatings.
3. Precision Control: It allows for complex seam geometries that are impossible with standard hot-air taping.
