Spin Welding Joint Design

Published by Leave your thoughts

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 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...

Companies Rely On Ultrasonic Welding

Published by Leave your thoughts

Back in the 1960s, the first plastic car was created using ultrasonic welding. Its creators had hoped that plastic cars would replace metal cars. It didn’t happen. Plastic cars never caught on. But ultrasonic welding did, and in a big way. Today, several industries including packaging companies, computer conglomerates, electrical...

Thermoplastic Polymers Suitable For Ultrasonic Plastic Welding

Published by Leave your thoughts

Understanding Ultrasonic Plastic Welding Ultrasonic plastic welding relies on the materials softening and not necessarily melting with increased temperature. This makes ultrasonic plastic welding suitable for thermoplastic polymers, but not thermosets. So what does this all mean? Most thermoplastic polymers have an amorphous structure with varying degrees of crystallinity (the...

Save Money and Invest In Used Welding Equipment

Published by Leave your thoughts

Plastic Assembly Systems (PAS) understands that it isn’t always possible to buy new, especially when faced with budget restraints. This is why PAS also deals in a wide variety of used welding equipment to address budget and assembly needs. Companies can feel secure that all used ultrasonic welding equipment from...
