Sonic Welding and Hot Stamping

In Ultrasonic Welding, high-frequency vibrations are locally applied to workpieces being held together under pressure to create a solid-state weld. It is especially used for joining dissimilar materials. In ultrasonic welding, there are no connective bolts, nails, soldering materials, or adhesives necessary to bind the materials together.

In-Depth Definition

Ultrasonic welding is an industrial technique whereby high-frequency ultrasonic acoustic vibrations are locally applied to workpieces being held together under pressure to create a solid-state weld. It is commonly used for plastics, and especially for joining dissimilar materials. In ultrasonic welding, there are no connective bolts, nails, soldering materials, or adhesives necessary to bind the materials together.

Applications

The applications of ultrasonic welding are extensive and are found in many industries including electrical and computer, automotive and aerospace, medical, and packaging. Whether two items can be ultrasonically welded is determined by their thickness. If they are too thick this process will not join them. This is the main obstacle in the welding of metals. However, wires, microcircuit connections, sheet metal, foils, ribbons and meshes are often joined using ultrasonic welding. Ultrasonic welding is a very popular technique for bonding thermoplastics. It is fast and easily automated with weld times often below one second and there is no ventilation system required to remove heat or exhaust. This type of welding is often used to build assemblies that are too small, too complex, or too delicate for more common welding techniques.

Hot Stamping

Hot Stamping is dry printing method in which a heated die and foil are used to apply graphics to a surface. Canyon Plastics, Inc. provides this service on-site to minimize costs to our clients. If your product requires Hot Stamping, be sure to contact us for a quote.

In-Depth Definition

Hot stamping is; 1) A die is mounted and heated, 2) Foil is positioned above the material to be imprinted, 3) A combination of heat, dwell time, pressure and stripping time control the quality of the stamp. Foil stamping is environmentally friendly due to it being a dry process. It does not use solvents or inks and does not create any harmful vapors.

A successful hot stamping job is directly related to the quality of the original artwork. In order to insure the highest quality reproduction of an imprint, the original artwork should be “camera-ready.” The better the artwork at the beginning, the better the imprint reproduction result. The key to a successful hot stamping job is three-fold; the first is creating a fixture to support the part firmly under the decorating area. Second, the fixture must also position the part for repeatability of the graphic location. And third, the fixture must allow the operator to easily load and unload the part from the fixture.
