Coils and Tooling

Need a part treated? Send us the heat treat pattern and we will design a coil that fits your needs!

The induction coil is a fundamental component to achieving the required metallurgical results for any induction application. Coils are carefully designed and built specifically for the work piece it encloses with many different factors taken into consideration. Work piece material, size, and geometry all influence the configuration of the coil and depending on the design, the difficulty can range anywhere from simple to complex.

Oftentimes minor modifications are needed to be made during the development process to perfect the heat treat pattern. Luckily, KVA employs the most highly skilled coil builders and machinists that produce accurate tolerances for consistent process ability. Here at KVA our full service tooling department will work with you to not only design, develop, and manufacture new coils, but also repair ones that are damaged as well.

3D Printed Induction Coils

3D printing allows for longevity and productivity to be improved...

3D printed coils are made as one piece so there are no brazed joints.

3D printing gives simplicity to the most complex designs...

3D printing allows for longevity and productivity to be improved...

The first coil is made the same as the last, making tolerance and repeatability no longer a concern.

3D printing opens up so many new possibilities...

We can make coils and their cooling pockets as intricate as needed.

KVA Tooling Examples

Single Shot

MIQ (Machine Integral Quench)

Single Shot

The position of the induction coil relative to the heated length of the part does not move. The part rotates while heating and quenching occur to ensure uniformity of pattern.

Multi-turn

MIQ (Machine Integral Quench)

Single Shot

Typically used where a long heated length is required or in line continuous applications where a soak time is required for the heat to reach the center of the component.

MIQ (Machine Integral Quench)

The quench is integrated right into the induction coil itself and typically has separate pockets for water cooling and quench delivery.

Non-MIQ

Quick Change

MIQ (Machine Integral Quench)

The quench is NOT part of the induction coil assembly and is often delivered in a different station or position like a quench barrel for example.

Quick Change

A quick change coil adapter is utilized to minimize down time when induction coil changes are frequent because of mixed production, and part or tooling changeovers.

Bus Bar

Quick Change

Bus bar systems are often used for power distribution and will connect the induction coil with the remotely positioned generator.
