This video features a C-Series Thermal Press performing heat swaging – a specialized form of heat staking – to secure piezoelectric sounders into a wearable medical device. This application requires precise control of heat and pressure to form secure, consistent stakes while protecting sensitive electronic components.
The system is equipped with a rotary indexing table that enables efficient, continuous operation by allowing parts to be loaded and unloaded in one station while the thermal process is performed in another. This configuration improves throughput and supports higher production capacity without sacrificing process control or repeatability.
Each assembly is placed into a custom-engineered nesting fixture designed to accurately locate and support the piezoelectric components. The fixture incorporates vacuum suction to securely hold the parts in place during the cycle, ensuring stability and preventing movements that could impact stake quality or alignment.
Once indexed into position, the thermal head applies controlled heat and pressure to form the swaged features. The tooling is specifically designed to match the geometry of the plastic material, enabling proper material flow and strong mechanical retention of the piezo elements without damaging the surrounding device structure.
This solution highlights how Thermal Press International systems combine precision thermal control, application-specific tooling, and automated indexing to deliver reliable, repeatable results. It is particularly well suited for medical and electronics applications where consistency, part integrity, and production efficiency are critical.
