This video demonstrates a Thermal Press International C-Series machine performing precision heat staking of threaded inserts into thermoplastic components. Heat staking is a highly controlled thermal assembly process that allows metal inserts to be securely embedded into plastic parts, creating strong, repeatable threads without introducing stress or damage to the surrounding matierial.
In this application, a customized nesting system is used to accurately locate and secure each component prior to processing. The fixture design ensures consistent alignment of both the plastic part and the threaded insert, which is critical for maintaining tight tolerances and repeatable results across high-volume production runs.
The system is equipped with a rotary indexing table that enhances operator efficiency and throughput. While one part is being processed under the thermal head, the operator can simultaneously load and unload parts in a separate station. This continuous workflow minimizes downtime and supports higher production capacity without compromising precision.
During the cycle, the thermal head applies controlled heat and force to the insert, allowing it to be cleanly embedded into the plastic. Process parameters such as temperature, dwell time, and applied force are precisely managed to ensure optimal material flow and strong mechanical retention. The result is a reliable, high-quality assembly with excellent pull-out strength and long-term durability.
This example highlights the flexibility of the C-Series platform, which can be configured with custom tooling, multi-station indexing tables, and process controls to support a wide range of heat staking applications across industries such as medical devices, electronics, automotive, and consumer products.
