Prepare For Plastic Welding

Take Time to Prepare Plastics For Welding The spectrum of plastic welding is wide. To start, there are many types of plastic welds available to plastic fabricators. You have ultrasonic welding, which consists of using an acoustic tool to transfer vibration energy through plastic parts. Vibrating molecules generate friction, which...

Various Plastic Welding Types

Look around you. Without even realizing it, you’re likely seeing how plastic welding makes things possible. From patio awnings to miniature airplanes, plastic welding is responsible for many things before your eyes, from the simplest toy doll to more complicated electronics. When multiple plastic can’t be fused together by adhesives,...

The Importance of Ultrasonic Plastic Welding

Ultrasonic plastic welding is a state-of-the-art technology used to form a permanent bond. Mechanical vibrations generate frictional heat until the plastic parts reach melting point and can be pressed together. The advantage of ultrasonic plastic welding is that it can be applied to embed metal parts into plastic. Fusing plastic...

Practical Uses of Ultrasonic Welders

Ultrasonic welders have multiple uses. Frequently applied to fuse small- and medium-size thermoplastic parts, ultrasonic welding machines are used in automotive applications, computers, electronics, toys, textiles and house appliances. How do ultrasonic welders work? Plastic parts are joined together through pressure and high frequency mechanical vibrations, which create frictional heat...

Variables to Consider In Ultrasonic Welding

The Components of Ultrasonic Welding In ultrasonic welding, there are three variables to consider: time, pressure and amplitude. All three need to be taken into consideration to control the process. But before we delve into these considerations, let’s start with the basics. Ultrasonic welding equipment consists of a machine press,...

How Does Spin Welding Work?

Spin welding is one technique that some consider to fall under ultrasonic welding. Whereas an ultrasonic or sonic welder uses vibrations to connect two pieces of plastic together, a spin welder uses circular motion or spinning. It is one of the most popular techniques to use when working with thermoplastics....

Heat Staking Design Guidelines

Standard Flared Stake Spherical Stake   Hollow Stake Staking a hollow boss produces a large, strong head without having to melt a large amount of material. Also, the hollow stake avoids sink mark on the opposite side of the component and enables the parts to be reassembled with self-tapping screws...

Spin Welding Joint Design

The Spin Welding process: Spin Welding Joint Design is critical for a proper spin weld. Spin welding is used to join two plastic parts which are spherical or cylindrical in shape. Frictional heat is generated at the mating surface (joint) by spinning one part (upper) against a fixtured (lower) part,...

Sonic Joint Design

Sonic Joint Design Perhaps the most critical facet of ultrasonic welding is joint design (the configuration of two mating surfaces). It should be considered when the parts to be welded are still in the design stage, and incorporated into the molded parts. There are a variety of joint designs, each...
