InfraStake, The Premiere IR Plastic Staking Technology
InfraStake is a clean staking process that uses focused infrared energy to heat and form a plastic boss. In this webinar, you’ll learn how InfraStake produces the tightest and strongest plastic assemblies.
Infrared plastic staking
InfraStake® is a tight, clean staking process that uses focused infrared energy to heat and form a plastic boss. This patented technology shines above other outdated, hot, and sticky staking processes.
The InfraStake Process
Reflective surfaces focus infrared energy from an IR lamp onto the plastic boss, heating it. Once the material is softened, a non-heated punch forms the boss into a stake.
Clamp
Module is positioned over the molded boss. The face of the concentrator clamps the part directly at the stake point.
Heat
Infrared (IR) lamp is illuminated. Light is focused radially on the plastic boss.
Form
IR lamp is switched off and the non-heated punch forms the semi-molten boss into a stake.
Retract
After the plastic has re-solidified, the punch retracts and the module retracts from the part.
Benefits of InfraStake
Strongest Stake Joints
InfraStake softens the boss before staking, which allows the material to flow easily and minimizes internal stresses that are common with other processes.
Tightest Stake Joints
InfraStake modules clamp each stake point directly, applying independent pressure, which ensures the joint is as tight as possible.
Reliable and Repeatable
Safe for Electronics
InfraStake doesn’t vibrate, and the energy is contained, which makes it safe to use with electronics and other sensitive components.
No Sticking
InfraStake heats the boss without touching it and forms it with a non-heated punch, so it doesn’t stick to even the most challenging materials, like nylon.
Low Energy Use
InfraStake uses a low-wattage bulb, using very little energy.
No Read Through
InfraStake does not use excessive heat or vibration, eliminating the risk of A-surface marking and read-through on aesthetic components.
Tamper Evident
InfraStake produces a permanent joint that shows evidence of tampering if the product is opened. In contrast, screws can be removed without evidence of tampering.

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
Why is my plastic sticking during the staking 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.
