Hot-plate welding is the process of welding two plastic parts together using a heated tooling plate. A weld rib or bead on each component is brought into contact with the hot plate. Heat conducts into the weld rib causing it to melt. The heated tool is then removed and the parts are pushed together until they bond to one another.

Two components are brought into contact with a heated tool. The heat conducts into melt ribs causing them to soften. Also called the ‘Heat Phase’.
The components are removed from the heated tool and it is retracted out of the way. Also called the ‘Changeover Phase’.
The components are brought together and a hold pressure is applied until the weld cools. Also called the ‘Weld Phase’.

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.
When considering the common plastics joining methods for assembling a new product, in the mix of options should be hot-plate welding. This low-force method of heating and bonding plastic parts has been around a long time. Contemporary machinery and tooling provide users with exceptional control and consistent weld results.
