Can you solvent bond polyethylene?

May 10, 2023 by James Stern 0 comments

Solvent bonding is generally not effective for polyethylene (PE) because it has low surface energy and poor chemical resistance to most solvents. However, some specialized solvents, such as 1,2-dichloroethane or trichloroethylene, can bond some types of polyethylene if the surface is first treated with a corona discharge or flame to increase surface energy. Additionally, a […]

What solvent is used to bond ABS?

May 10, 2023 by James Stern 0 comments

Acrylonitrile butadiene styrene (ABS) can be solvent welded using a variety of solvents, but the most commonly used solvent is acetone. Acetone is a fast-acting solvent that works well on ABS because it can dissolve the plastic and create a strong bond between the two pieces. However, it is important to note that acetone can […]

What solvent is used to weld acrylic?

May 10, 2023 by James Stern 0 comments

Acrylic, also known as polymethyl methacrylate (PMMA), is a thermoplastic material that can be easily welded using a solvent. The solvent used for welding acrylic is called Methylene Chloride (MC) or Dichloromethane. Methylene Chloride is a colorless, volatile liquid that has a slightly sweet odor. It has a low boiling point and evaporates quickly, making […]

Why use a mylar washer in ultrasonic welding?

Apr 21, 2023 by James Stern 0 comments

A Mylar washer is a type of insulating washer used in ultrasonic welding to electrically insulate the horn from the stack or transducer. It is made from a thin, durable, and high-temperature resistant material called Mylar. The Mylar washer serves several purposes in ultrasonic welding: When establishing a maintenance schedule for ultrasonic welding, it is […]

How do I establish a maintenance schedule for ultrasonic welding?

Apr 21, 2023 by James Stern 0 comments

Establishing a maintenance schedule for ultrasonic welding is an important step in ensuring that the equipment remains in good working condition and can operate efficiently over time. Here are some steps to help you establish a maintenance schedule: By following these steps, you can establish a maintenance schedule for your ultrasonic welding equipment that will […]

What is ultrasonic welding?

Apr 21, 2023 by James Stern 0 comments

Ultrasonic welding is a manufacturing process used to join two thermoplastic parts together. It uses high-frequency mechanical vibrations, typically between 20 kHz and 40 kHz, to create heat at the joint interface, melting the material and bonding the parts together. Ultrasonic welding is widely used in industries such as automotive, medical, consumer goods, and packaging. […]

What is part marking in ultrasonic welding?

Apr 21, 2023 by James Stern 0 comments

Part marking can cause issues in ultrasonic welding for several reasons. Firstly, it can indicate that the welding process is not optimized, as excessive pressure or energy can cause the plastic to deform or even break. This can lead to inconsistent or weak welds, which can compromise the integrity of the product. Additionally, part marking […]

What is the hold time in ultrasonic welding?

Apr 21, 2023 by James Stern 0 comments

The hold time in ultrasonic welding refers to the duration of time that the force is applied after the ultrasonic energy has stopped. It is the period during which the plastic cools down and solidifies, forming a strong bond. The hold time is an important parameter in ultrasonic welding as it affects the strength and […]

What is a hermetic seal in ultrasonic welding?

Apr 21, 2023 by James Stern 0 comments

A hermetic seal in ultrasonic welding refers to a seal that is airtight and does not allow any air, gas or liquid to pass through. In ultrasonic welding, hermetic seals are achieved by applying high-frequency ultrasonic vibrations and pressure to the materials being welded, causing them to melt and fuse together. This type of seal […]

What is a generator used for in ultrasonic welding?

Apr 21, 2023 by James Stern 0 comments

In ultrasonic welding, the generator is the power supply that produces the high-frequency electrical energy needed to drive the transducer and convert it into ultrasonic mechanical vibrations. The generator converts the input line power into a high-frequency AC signal that is sent to the transducer, which in turn produces high-frequency mechanical vibrations. The generator provides […]
