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.

InfraStake: The Solution for Strong, Reliable Plastic Assemblies

InfraStake: The Solution for Strong, Reliable Plastic Assemblies

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.
