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, thus welding the assembly together. Spin welding is a fast process that works well with large and … [Read more...] about Spin Welding 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 with specific features and advantages. Their selection is determined by such factors as type of … [Read more...] about Sonic Joint Design
