Our weapon for air locking and waterproofing is welding. Not all fabric can be weldable but only for those coated and laminated.

There are 3 different methods for welding.

High Frequency Welding

Localized High Frequency electromagnetic waves heat up the molecules exceeding its melting point. The melted molecules then be bonded between fabric surfaces. Also known as Radio Frequency welding.

Heat Sealing Welding

Hot tooling, with a shape that matches the welded joint geometry, is pressed over the fabric. Heat is transferred to melt the interface. The tooling is pressed until the welded joint cools and re-solidifies to create a permanent bond.

Ultra Sonic Welding

Ultra Sonic Acoustic vibrations are locally applied to fabric being held together under pressure to create a solid-state weld.

Welded seam is reinforced by Heat Sealing for maximum strength and reliability.
