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. It also allows the machine to control and monitor the forces throughout the process. Being able to measure the melt and seal forces means you can quickly detect and correct issues.
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.
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.
