Spin Welding
Servo-driven spin welding designed around your applicationGet smart weld joints with our spin welding machines
When you need strong, leak-proof welds, the Vortex Eminence Spin Welder is an ideal solution. Whatever your application, we configure our servo-driven machines to work specifically with your part in mind. Whether your assembly has a small diameter or a large one, we have a spin welding solution that will meet your needs.
How does spin welding work?
Spin welding is a method of joining plastic components together with surface friction concentrated in a circular weld joint. One part is spun relative to another and force is applied, causing the material to heat and melt. The spinning process stops and the parts continue to be pressed together while they bond together.
Spin
One component spins, causing surface friction against the fixed component.
Melt
Friction between the two components generates heat, causing the contact surfaces to melt.
Hold
As the spinning stops, the weld joint resolidifies under pressure and they join.
Servo-driven spin welders for torque, force, and velocity control
A proper joint design is critical to achieving a strong, leak-proof weld with minimal flash and a wide process window. The Vortex Eminence is both scalable and integrable, so it is a perfect solution for manufacturers and integrators alike. Depending on your needs, we configure the torque and force output to weld parts of all shapes and sizes.

What is the difference between plastic welding and plastic staking?
When designing a plastic assembly, one of the earliest and most important decisions engineers face is how the parts will be joined. Two of the most common options are plastic welding and plastic staking. While both methods are widely used, they serve very different purposes and lead to different outcomes in terms of strength, appearance, cost, and performance.
If you’re evaluating plastic joining methods early in your design process, understanding the difference between plastic welding and plastic staking can help you avoid costly redesigns and manufacturing challenges later on.

Plastic Joining: Make or Break Factors
“What technology should I use to join my application?” is one of the most common questions we get from customers looking to ensure the best performance and durability for their project. Unfortunately, there’s no one-size-fits-all answer to that question. Several factors go into whether or not an application is compatible with different plastic welding technologies, and understanding them is key to making an informed decision.
Designing for Strength: What to Consider in Plastic Part Design
One of the more difficult questions I get asked by our customers is how to optimize assemblies for strength. This is an incredibly complex question but an important one when it comes to product development. Simulations like Finite Element Analysis are always a helpful tool, but FEA only provides some of the information, not all of it. Here are some questions to begin with during the development process
The Guide to Switch from Adhesive Bonding to Plastic Welding
In manufacturing and product assembly, choosing the proper joining method is critical to ensure the end product’s strength, durability, and efficiency. Adhesive bonding is a popular method for assembling plastic parts. But as product demand increases, the need for faster and more cost-effective joining methods arises. Plastic welding is a popular alternative to adhesive bonding that produces more durable, reliable, and cost-effective assemblies.
3 spin welding design mistakes to avoid
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.
4 spin welding tips to think about
Spin welding is a really good method for joining thermoplastics. It’s easy to understand, the tooling is simple, the strength results are impressive, and the process is really robust. Keeping those results consistent and managing weld flash control can be a challenge, however.
