Ultrasonic welding is typically faster than hot plate welding, but there are limitations. Ultrasonic welding typically isn’t suited for joining larger pieces together. The types of plastic used to create the two pieces being joined must also be a close match, both chemically and in terms of their melting points. Within these constraints, however, ultrasonic welding is a fast and cost-effective way to join plastic pieces together.
Hot Plate Welding
Hot plate welding involves a longer cool-down period than ultrasonic welding, so it’s usually not as fast, but it can be used to join much larger pieces (up to five feet in length). It can also be used to join a wider range of different thermoplastics together, as long as their melting points fall below their decomposition temperature. Hot plate welding can also handle much greater complexity of joint geometry when needed in a weld.
Each new link added to your supply chain is a chance for delays or mistakes to happen. Simplifying your supply chain saves time and money.
