SAET INDUCTION
Additively manufactured copper inductors engineered for the widest range of hardening profiles — from simple scan hardening to the most complex single-shot geometries.
No matter the size or complexity, we deliver advanced solutions for even the most demanding induction processes and coil designs.
Complex induction coils often require non-standard geometries, tight spatial integration, or the ability to follow irregular component profiles. In these applications, inductor design becomes a key factor in ensuring uniform heating, high efficiency, and consistent process performance.
Whether working within limited space or integrating with surrounding components and tooling, we carefully evaluate multiple manufacturing approaches to identify the optimal solution. Each design is tailored according to geometry, tolerances, and specific application requirements.
For the most challenging cases, we also leverage advanced and complementary manufacturing technologies — including 3D printing — to unlock greater design freedom and accelerate development.
Every advantage compounds — longer coil life means less downtime, fewer changeovers, and more predictable production planning.
One continuous copper structure — the primary cause of water leaks and premature failure is permanently eliminated.
Free-form internal channels follow the exact coil contour — impossible with bent copper tube.
Independent testing confirms significantly longer coil life across automotive and industrial applications.
Hairpin, single-shot, multi-turn — any shape achievable in CAD can be produced without compromise.
Every coil is printed from the same CAD file — identical geometry, consistent and predictable hardening results.
Longer life, less downtime, faster re-ordering — lower total cost of induction hardening operations.
A direct comparison of the two manufacturing approaches across the factors that matter most in production.
| Parameter | Traditional (bent & brazed) | 3D Printed Coils |
|---|---|---|
| Brazed joints | Multiple — primary failure point | None — monolithic structure |
| Service life | Baseline | 3–4× longer (validated) |
| Dimensional repeatability | Operator-dependent variation | CAD-identical, batch after batch |
| Internal cooling geometry | Limited by tube bending | Free-form channels follow coil contour |
| Complex geometries | Limited by bending & brazing | Any geometry achievable in CAD |
| Re-order speed | Fabrication from scratch | Re-print from stored CAD file |
| Machine downtime | Higher — more frequent replacement | Lower — extended coil life |
