If you’re familiar with plastic welding, you’ve probably encountered ultrasonic welding. It’s the most well-known plastic welding technology. But just because it’s popular, doesn’t mean it is the best choice for every application. It has many benefits, but also some drawbacks. What do you do if ultrasonic welding isn’t your best option? And how do you know?
Trying to hot plate weld small brackets, or ports onto a large complex part can be tough and expensive in a standard machine. These types of applications often need a modular, configurable solution to fit around the parts. Often, the main piece has several small components, each needing a welding operation. For example, many automotive underhood ducts are long and meandering and have a couple of ports and brackets.
Servo-controlled hot plate welders completely revolutionize the hot-plate welding process. Take it from Extol, we started the servo movement with the Rapid Conductor hot plate welder. Our welders use servo-motors to control the platens and weld strong, repeatable parts.
If you do any hot-plate welding, you should start monitoring melt force to improve your weld consistency and quality. Extol’s Rapid Conductor hot-plate welder is equipped standard with three servo-driven platens: the upper and lower press platens, and the heated platen. Servo control eliminates the need for hard stops and ensures that all the pressure applied by the welder goes directly into the components being welded.
When welding parts in production, you want to have reliable and consistent assemblies. You may have been churning out ‘good’ parts for years, but suddenly you are finding part inconsistencies and failures when none of your parameters have changed! What happened?
We all love options – colors, cars, hobbies, music, and of course our favorite, plastic welding!
Let’s talk about a few of the differences between vibration and hot-plate welding that may help in discerning when to choose one over the other. Ah, but first we should briefly review the two welding processes.
