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’.

Ultrasonic welding vs. Hot-plate welding. When you picked your March Madness teams, you considered strength of schedule and how their weaknesses matched up. Let’s talk about welding plastic parts for life science applications and how weld strength and leak (weakness) compare between ultrasonic welding (USW) and hot-plate welding (HPW).
In our last blog post, we discussed that you only need 2 things to weld plastic, heat and pressure. It really is that simple. However, there are 4 common mistakes that people often make when setting up a hot-plate weld that can prevent adequate heat and pressure from being achieved. Today we’re going to explore these mistakes and how a strong weld can be attained by avoiding them.
Believe it or not, you only need two things to weld plastic parts together. Heat and pressure. Just look at hot-plate welding as an example. For those of you who may be unfamiliar with the hot-plate welding process, it goes like this: Two parts are…
