What makes up the probe configuration in ultrasonic welding?

Apr 21, 2023 by James Stern 0 comments

The probe configuration in ultrasonic welding typically consists of a converter, a booster, and a horn. The converter is a piezoelectric transducer that converts electrical energy into mechanical vibration. The booster is a metal component that amplifies and modifies the amplitude and displacement of the vibration generated by the converter. The horn is attached to […]

What are the phases of welding in ultrasonic welding?

Apr 21, 2023 by James Stern 0 comments

In ultrasonic welding, there are typically four phases of welding: The parameters such as amplitude, pressure, and time can be varied during each phase to optimize the welding process for a particular application.

What are bad part limits in ultrasonic welding?

Apr 21, 2023 by James Stern 0 comments

Bad part limits in ultrasonic welding refer to the set of conditions or characteristics of a welded part that deem it unacceptable or unsatisfactory for its intended use. These limits are typically established during the development of the welding process and are based on a range of factors, including the design of the part, the […]

What is welding by position or absolute distance mean in ultrasonic welding?

Apr 21, 2023 by James Stern 0 comments

Welding by position or absolute distance in ultrasonic welding refers to controlling the weld process based on the actual position or distance between the horn and the workpiece. This method is typically used when the parts being welded are not of uniform size or shape, or when the positioning of the parts is critical to […]

What does Weld By Distance mean in ultrasonic welding?

Apr 21, 2023 by James Stern 0 comments

Welding by distance is a method of controlling the ultrasonic welding process based on the distance traveled by the ultrasonic horn during the welding cycle. In this method, the ultrasonic generator is programmed to deliver a specific amount of energy to the joint, based on the distance that the horn has traveled during the welding […]

What does Weld By Energy mean in ultrasonic welding?

Apr 21, 2023 by James Stern 0 comments

Welding by energy is a method of controlling the ultrasonic welding process based on the amount of energy delivered to the joint, rather than the duration of the welding cycle. In this method, the ultrasonic generator is programmed to deliver a specific amount of energy to the joint, based on factors such as the material […]

What is Weld By Time in ultrasonic welding?

Apr 21, 2023 by James Stern 0 comments

Welding by time is a method of controlling the duration of ultrasonic energy applied during the welding process. In this method, the ultrasonic generator is programmed to deliver a specific amount of energy to the parts being welded, based on the length of time that the ultrasonic horn is in contact with the joint. During […]

What is a shear joint in ultrasonic welding?

Apr 21, 2023 by James Stern 0 comments

A shear joint is a type of joint commonly used in ultrasonic welding that involves joining two materials in a parallel configuration. In this joint, the two materials are brought into contact and the ultrasonic horn is applied perpendicular to the joint line, causing a shearing force that creates frictional heat and melts the materials. […]

How do mold release agents affect in ultrasonic welding?

Apr 21, 2023 by James Stern 0 comments

Mold release agents are typically used to facilitate the release of plastic parts from the mold during the injection molding process. However, these agents can have an impact on the quality of ultrasonic welding if they are not properly removed prior to welding. If mold release agents are present on the surface of the plastic […]

How does hygroscopicity affect in ultrasonic welding?

Apr 21, 2023 by James Stern 0 comments

Hygroscopicity is the ability of a material to absorb moisture from the environment. In ultrasonic welding, the presence of moisture can have a significant impact on the quality of the weld. When a plastic material with high hygroscopicity is used for ultrasonic welding, the moisture absorbed by the material can lead to a decrease in […]
