Plastic Welding Processes
Plastic welding is the process of heating up two plastic parts and bonding them together by applying pressure. There are several different welding technologies that differ in their application of heat and pressure, but the basic steps are heat, apply pressure (force), and cool. The weld created between the parts is a strong molecular bond and depending on the welding technology, is hermetically sealed. Learn more about specific joining processes below.
Design engineers often ask us, “How strong will my staked joint be?” Usually, they’re designing a plastic assembly that needs to be staked, and they need to know how to design the part.
So, you’ve seen the new revolutionary nanoSTAKE technology and you are wondering how you can get it on your next plastic staking application. There are two great ways to do that. You can purchase a turnkey nanoSTAKE machine directly from Extol, or you can purchase nanoSTAKE through your preferred integrator. Either way, you get expert technology service from our knowledgeable team. Let’s talk more about what is included in a nanoSTAKE integration package and how they work.
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.
In the InfraStake process, infrared energy comes from a tungsten halogen lamp inside the module. Reflective surfaces inside the module focus the IR energy from the lamp onto a plastic boss to heat it prior to staking. So, the output of the lamp is an important factor in the InfraStake process.
Spin welding is a pretty straightforward process. You spin one plastic component against another and the friction between them causes the material in the weld joint to melt. Even with a welding process this simple, it’s easy to make design mistakes that will cause headaches later. Here are three common mistakes that you should always avoid.
Mark recalled seeing a demo of Extol’s InfraStake technology a few months prior and was drawn to InfraStake’s built-in clamping feature that ensures tight stakes. Mark was hopeful that InfraStake would be a good fit for the door panel line, but wanted confirmation that the technology could meet the cycle time, strength, and assembly tightness requirements. That’s when our Applications Lab, the first of Extol’s wide array of customer-supporting service groups, stepped in to help.
