Battery & capacitor manufacturers rely on Sonobond’s Ultrasonic SonoWeld® 1600 and Dual Head Spot Welders to join up to 100 layers of foil as thin as seven microns without tearing. Our units weld foil-to-foil, -tabs & -terminals, battery pouches and HV terminations.

These welders, made in the USA, are used in the assembly of rechargeable batteries for all-electric & hybrid automobiles, and for the backup storage batteries needed in alternative energy systems like wind and solar.

Precise, dependable, solid-state and highly conductive welds are assured with our unique, patented Wedge-Reed Bonding System. Sonobond holds more than 150 patents, including the first for ultrasonic metal welding issued in 1960. Visit our website to order FREE SAMPLE WELDS made with your specific materials.

Herrmann Ultrasonics is a machine and system supplier that offers optimized solutions for ultrasonic welding used in the production of lithium-ion batteries, battery components, and other industrial applications. Our unique stack mount allows for faster tooling alignment, and repeatable change overs, resulting in greater production up time. Our ultrasonic welding systems meet the highest standards for weld quality and comply with today’s requirements for process monitoring, quality assurance, and data acquisition. Application-specific technical consulting is provided in our ultrasonic laboratories.

Leading battery & capacitor manufacturers rely on Sonobond’s ultrasonic metal welders to produce precise, environmentally-friendly, high performance foil-to-foil, -tab and -terminal welds; battery pouches & HV terminations. They’re ideal for Lithium-Ion, Ni-CD and Ni-MH battery assembly.

Sonobond invented ultrasonic metal welding in 1960, and our welders, made in the USA, use our patented Wedge-Reed System, which is essential for producing strong, solid-state, highly conductive welds without metallurgical defects. We also developed the first ultrasonic welder to join up to 100 layers of copper or aluminum foils as thin as seven microns, and in just one pulse.

We offer no cost/no obligation sample welds made with your specific materials so you can see the results before you buy.

Dynatrol® Density meters measure sulfuric acid in the manufacturing of lead –acid automobile batteries. The Dynatrol® System provides continuous % CONCENTRATION measurement at process conditions, performing real calculation of density change with temperature. It can also correct to various reference temps (Ex. 15C, 20C, 60, 68F or other temperatures). This durable equipment is made with ACID RESISTANT METALS – Hastelloy C, Carpenter 20
Dynatrol® Density Cells provides fast, precise measurement while withstanding temperatures up to 300° and abuse from sulfuric acid.
