Back-to-back hook and loop ultrasonic welding machines are specialized equipment designed for welding materials such as hook and loop fasteners. Below is a detailed introduction to these two types of equipment:

Working Principle of Back-to-back Hook and Loop Ultrasonic Welding Machine:

Utilizes ultrasonic plastic welding technology to convert ultrasonic energy into high-frequency vibrations applied to the hook and loop fastener.

Transmits ultrasonic energy to the welding area through the upper welding component. Due to the high acoustic resistance at the interface between the two welding surfaces, localized high temperatures are generated.

Because hook and loop fasteners have poor thermal conductivity, the high temperatures concentrated in the welding area cause the contact surfaces of the two plastics to melt rapidly. Under applied pressure, they fuse into a single unit.

Features:

High welding quality, using original Japanese components.

Four-point balanced adjustment tooling for easy welding head adjustment.

Equipped with an automatic overload protection device for long-lasting durability.

Electric lifting body for easy and convenient operation with high strength.

Robust and durable overall design with excellent streamlined appearance.

Applications:

Specifically used for welding hook and loop fasteners, adhesive hook and loop tapes, hook and loop straps, adhesive-backed hook and loop tapes, nylon hook and loop tapes, etc.

Suitable for use in the automotive industry, electronics industry, medical industry, home appliance industry, non-woven apparel, office supplies, packaging industry, toy industry, etc.
