BRDASON ultrasonics

An ultrasonic wire splicer is a specialized device that permanently joins (splices) metal wires using high-frequency ultrasonic vibrations.‌



‌Joining Process:‌


The wires to be spliced are positioned firmly between the sonotrode horn and a fixed ‌anvil‌.
The horn presses down onto the wires while vibrating intensely at ultrasonic frequencies.
This vibration creates rapid ‌friction‌ and localized ‌plastic deformation‌ at the interface of the wire strands.
The friction breaks down surface oxides and contaminants.
The plastic deformation allows the clean metal surfaces to interlock and bond at an atomic level under pressure.

‌Key Characteristics:‌


‌Cold Process:‌ Generates minimal external heat, avoiding damage to wire insulation or sensitive components.
‌Flux/Solder Free:‌ Requires no consumables like solder or flux.
‌Strong & Reliable Bond:‌ Creates a metallurgical weld often stronger than the wire itself, with low electrical resistance.
‌Clean:‌ Produces no fumes or residue.
‌Fast:‌ Joining cycle times are typically very fast (often less than a second).
‌Automation Friendly:‌ Easily integrated into automated production lines.
‌Applications:‌ Widely used for splicing fine wires in electronics (e.g., coils, sensors, micro-motors, transformers, medical devices), automotive components, aerospace wiring, and jewelry manufacturing.

What is ultrasonic degating ?

The separation of injection-moulded parts from their runner systems through the introduction of ultrasonic
energy into the area of the gate is referred to as ultrasonic degating*. These gate sections, when ultrasonically excited, reach high temperatures and melt due to a high degree of intermolecular excitation and internal friction.
This information sheet describes ultrasonic degating and provides design guidelines for its use.


The advantages of ultrasonic degating include:


• Speed of operation, with a typical cycle time of
less than one second.
• No stress developed in plastic component.
• A clean break at the part surface.
• Many parts may be degated and automatically separated into bins.


Mechanics of Ultrasonic Degating
The vibrating horn contacts the runner as closely to the part as possible with relatively light force, generally 20 to 40 pounds, imparting maximum energy into the runner system. The mechanical vibrations

generate a standing wave of energy down the runner through the gate area and into the part
