Single and double head ultrasonic spot welding machines support the documented configuration and application requirements for nonwoven fabric, film and thermoplastic material joining.

Single and Double Head Ultrasonic Spot Welding Machines for Nonwoven Fabric and Thermoplastic Materials

This product range includes single-head and double-head ultrasonic spot welding machines for precise bonding of thermoplastic materials without needles, thread or adhesive. Typical applications include welding nonwoven bag handles, face mask ear loops and surgical gown ties. The machines are compatible with composite fabrics, synthetic fiber cloth, nylon, knitted fabrics, nonwoven materials, spray-bonded cotton, thermoplastic films including polyethylene paper, polyethylene and polyurethane, and plastic sheets such as ABS.

Available Machine Configurations

Double Head Ultrasonic Spot Welding Machine

The dual-head ultrasonic welder is designed for applications requiring two welding points. Both heads can operate simultaneously or independently, allowing two points to be formed in one cycle. The head angles can be adjusted for long, symmetrical or larger workpieces.

• Dual welding heads for simultaneous or independent operation
• Two welding points formed in one cycle
• Independent frequency control for stable energy output
• Touch-screen parameter control and storage
• Suitable for nonwoven fabric, PE, EVA and plastic components

Single Head Ultrasonic Spot Welding Machine

The compact single-head ultrasonic spot welder is intended for single-point bonding, small production spaces, small batches and multi-style orders. Localized ultrasonic heating forms a clean weld without scorching the fabric or plastic.

• Compact footprint and flexible workshop installation
• Single-point instantaneous ultrasonic welding
• Stable energy control for continuous production
• Touch-screen parameter adjustment
• Suitable for nonwoven fabric, EVA, PE film and synthetic fabrics

Single And Double Head Ultrasonic Applications

This equipment is designed for consistent output, practical changeover and dependable process control. The existing technical parameters, specification tables, images and layout remain unchanged. Confirm material format, target capacity, utilities and optional modules with the engineering team before ordering.

Sunlay Auto provides application guidance so purchasing and production teams can compare documented capabilities with their actual workflow, installation space and quality requirements.

For a suitable configuration, confirm the workpiece material, welding-point position, tooling pattern, power supply and intended operating process before order confirmation. This helps align the machine configuration with the actual application without changing the documented machine specifications.
