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.

In the world of plastic assembly, finding a solution that balances high strength, aesthetic quality, and process repeatability can be a challenge. Traditional methods like ultrasonic welding or hot-air staking often come with trade-offs, such as material stringing, vibration damage to sensitive electronics, or inconsistent joint tightness.
InfraStake® represents a shift in plastic staking technology. By utilizing infrared (IR) energy to precisely melt plastic bosses, it provides a mechanical joint that is as strong as it is visually clean. Here is a breakdown of how the technology works and why it is becoming the preferred choice for complex manufacturing applications.

“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.

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

This question has been posed to me by many customers. I hear statements like, “The machine works great for a long time, and then we suddenly get all of this sticking and stringing.” This issue is somewhat common in most types of staking technologies and varies in severity among different thermoplastic materials.
