U.S. Heatstake Blog
Long-form articles from the U.S. Heatstake engineering team on impulse heat staking, brass insert installation, custom automation, and the design and process choices that decide whether a thermoplastic assembly works or fails on the line. Written by people who build heat staking equipment for a living and have spent years watching customer parts succeed or fail under it.
Topics covered include heat staking design rules, boss and stud geometry, equipment selection (benchtop vs inline vs custom cells), material compatibility, troubleshooting common failures, and comparisons against alternative joining processes such as ultrasonic welding, mechanical fasteners, and adhesives. Most posts are practical guides: design rules with real numbers, troubleshooting checklists, and honest discussions of when heat staking is not the right answer for a given part.

Editorial Approach
We write the articles we wish existed when we started in this industry: specific, opinionated, and honest about tradeoffs. If a competing process fits your part better than ours, we say so. If a particular resin is a bad fit for heat staking, we say that too. The goal is to help readers make the right call for their specific part, not to sell them equipment that does not fit.
