Impulse Heat Staking Equipment — A Modern Alternative to Hot Probe

U.S. Heatstake designs and manufactures impulse-based heat staking and brass insert installation systems for plastic assembly. Based in Roanoke, Indiana, we build benchtop presses, custom automation, and process tooling for automotive, medical device, electronics, and consumer-product manufacturers across North America. Every press and every tool we ship is engineered around the part it has to assemble, not pulled from a catalogue and hoped to fit.

Our impulse technology heats on demand and cools under compressed air, eliminating the sticking, stringing, drift, and cosmetic witness marks that plague traditional hot-probe heat staking. Patent-pending Weld by Energy control delivers a metered amount of energy per joint — one setting per stake, repeatable across long production runs, drift-prone resins, and operator changes. The tip heats for the brief moment it needs to soften the boss, the head forms under controlled load, the tip cools, and the press retracts without dragging molten plastic across your A-surface.

Our presses support up to eight bosses staked simultaneously with 0.1 mm encoder accuracy on the head position, multi-station automation cells for inline production, and tooling engineered around your specific part geometry. From a single benchtop press through a fully integrated robotic assembly cell, we cover the full range of heat staking production volumes — whether you build hundreds of parts per shift or hundreds of thousands.

What We Build

Three product lines cover most heat staking work. Impulse Heat Staking forms plastic bosses into permanent rivet-style heads that capture brackets, lenses, PCBs, and sub-assemblies inside a plastic housing. Brass Insert Installation heats and presses threaded brass, stainless, or aluminium inserts into moulded pilot holes, giving plastic parts permanent reusable metal threads. Custom Automation wraps that staking technology in multi-station rotary cells, inline integration with moulding lines, robotic part handling, and turnkey assembly systems with PLC controls and process documentation.

The flagship machine is the Model BTP Benchtop Press: production-grade pneumatic ram, impulse-heated tooling, 0.1 mm encoder accuracy, support for up to eight stakes or inserts per cycle, and one-setting-per-joint cycle behaviour that does not drift between operators, shifts, or resin batches.

Industries We Serve

We work with automotive Tier 1 and Tier 2 suppliers on dashboard clusters, lighting bezels, HVAC ducts, sensor housings, and EV battery enclosures. Medical device manufacturers use our presses for diagnostic instruments, drug delivery cassettes, single-use device assembly, and PCB retention inside sealed enclosures. Electronics programmes use heat staking for PCB-into-housing assembly, sensor modules, IoT devices, and connector retention. Consumer product brands use it for small appliances, personal care devices, lighting, and packaging where unit cost has to stay low and the housing has to look right out of the box.

Why U.S. Heatstake

Cosmetic-grade cycle behaviour, no sticking or stringing on tip retract, repeatable energy-metered joints across long production runs, tooling engineered around your geometry, and an engineering team that will tell you honestly when heat staking is not the right fit for your part.
