The medical sector imposes some of the highest technical requirements in the industry: absolute precision, uncompromising reliability and compliance with the strictest regulations. From surgical instruments to active implant devices, every application requires perfect thermal control and reproducible processes. AET Group, through ID Partner, designs and manufactures bespoke induction heating systems tailored to the specific challenges of the medical and dental sectors.
The medical sector is subject to particularly stringent regulatory and technical requirements. Every thermal process—whether it involves the manufacture of surgical instruments, the soldering of medical electronic devices, or the sterilisation of equipment—must ensure full traceability, perfect repeatability, and compliance with current standards (UL, ISO, CE). Even the slightest thermal deviation can compromise the integrity of the device, jeopardise patient safety and lead to regulatory non-compliance with critical consequences.
The increasing miniaturisation of medical devices and the rise of active implants also pose new challenges: it is becoming necessary to concentrate precise thermal energy in extremely small, sometimes inaccessible areas, without affecting surrounding components or tissues.
Conventional heating techniques (oxyacetylene flame, electric resistance, heat transfer fluids) have significant limitations in a medical context: risks associated with open flames, high thermal inertia, temperature gradients that are difficult to control, and insufficient process traceability.
For applications such as brazing miniaturised contacts, tube forming, annealing medical wires or sterilising instruments, these methods do not allow the level of precision, safety and repeatability required by the medical industry to be achieved.
Furthermore, certain cutting-edge applications, such as wireless power transmission to implantable devices, require highly specialised induction architectures that combine high reactive power with a compact footprint, whilst complying with strict electromagnetic compatibility standards.
ID Partner has developed an induction system capable of transmitting energy wirelessly to a prosthesis implanted beneath several layers of muscle. Despite having a reactive power of 125,000 VA, the entire system fits into a piece of hand luggage and complies with UL standards.
Induction heating is a technological solution particularly well-suited to the requirements of the medical sector. With no flame or contact, heat is generated directly and exclusively in the targeted area, thereby eliminating any risk of contamination or damage to adjacent components. This precision in heating, combined with the complete absence of thermal inertia, enables the levels of repeatability essential for the manufacture of medical devices to be achieved.
The systems designed by ID Partner natively incorporate programmable thermal profile management and full traceability of each heating cycle, thereby meeting the documentation requirements of regulated environments. This approach covers a wide range of applications: soldering of contacts and medical electronic devices, annealing of surgical wires, hardening of instruments, sterilisation of equipment, tube forming, and wireless power transmission to active implants.
The integration of ID Partner into the AET Group has strengthened the group’s capabilities in the design, manufacture and integration of induction heating systems for the most demanding medical applications. ID Partner brings transformative expertise in the design of bespoke inductors, tailored to the complex geometries and regulatory requirements specific to the medical sector.
