Tailor-made replacement and special solutions from INDUGO
A defective or worn inductor does not necessarily have to be replaced at high cost by the original manufacturer. In many cases, inductor reproduction is the more economical and faster solution – especially when original parts are difficult to obtain, discontinued, or disproportionately expensive.
INDUGO supports companies with the precise reproduction of inductors – independent of manufacturer, application-specific, and based on solid engineering. Whether replacement for existing production lines, reconstruction of damaged tools, or manufacturing of custom inductors: the goal is always a reliable solution for continued production use.
What does inductor reproduction mean?
In inductor reproduction, an existing inductor is reproduced or specifically further developed based on a sample, a drawing, or available measurement data. The aim is not merely to copy the outer shape. What matters is that the process-relevant characteristics of the original are transferred as accurately as possible or, where appropriate, technically improved.
This includes in particular the geometry of the inductor, the structure and routing of the windings, as well as the design of the connection and cooling system. Equally important are the distance to the workpiece, the thermal and electrical load during ongoing operation, and the specific installation situation in the existing system.
A professional reproduction is therefore not just a simple spare part, but a functionally critical tool that must be precisely matched to the respective process.
When does inductor reproduction make sense?
Inductor reproduction is particularly advisable when a repair is no longer sufficient or no suitable original part is available. Typical cases include:
- the existing inductor is severely damaged or worn
- cost‑effective inductor repair is no longer possible
- the original manufacturer no longer supplies parts or only with long lead times
- spare parts are very expensive
- existing inductors need to be adapted for new applications
- older systems require a functionally identical replacement
- special geometries are needed for specific workpieces
Which inductors can be reproduced?
These inductors are precisely matched to the workpiece geometry. They are often used where defined heating zones or precise hardness patterns are required.
Internal inductors are used to heat bores, internal surfaces, or internal contours. Their reproduction requires high precision in geometry and cooling design.
External inductors are used for heating external areas of the workpiece, for example on shafts, rings, or rotationally symmetrical components.
Depending on the process requirements, different numbers of turns and designs may be necessary. Exact reproduction ensures the desired coupling and heating characteristics.
For geometries that are difficult to access or for local heating zones, special designs are often used. In these cases, the reproduction of custom inductors is particularly in demand.
Custom inductors for existing systems and new applications
Not every inductor reproduction is a pure 1:1 copy. In many projects, the task is to develop custom inductors that are matched to an existing system, a new workpiece type, or changed process requirements. INDUGO supports companies in implementing customer‑specific and tailor‑made inductors for various applications – for example for:
- induction hardening
- induction brazing
- preheating processes
- joining and shrink‑fit processes
- automated series production
- special industrial applications
How does inductor reproduction work?
Analysis of the existing inductor
At the outset, the existing inductor is examined. Geometry, wear, material condition, cooling layout, connections, and process‑relevant characteristics are evaluated.
Recording of dimensions and functional characteristics
Depending on the initial situation, reproduction is carried out on the basis of sample parts, drawings, photos, measurement data, or technical specifications. Even for damaged components, a reliable reconstruction can often be created.
Technical assessment
It is then evaluated whether a 1:1 reproduction is appropriate or whether an adaptation offers advantages – for example in terms of service life, manufacturability, cooling, or installation conditions.
Manufacturing of the new inductor
In the next step, the new component is manufactured. Depending on the requirements, various processes can be used, such as brazing, welding, machining, or other modern manufacturing methods.
Quality inspection and release
Before being put into operation, geometry, workmanship, tightness, and function are tested. This results in an inductor replacement designed for industrial use.
Why precision is so important in inductor reproduction
An inductor has a direct impact on the quality of the induction process. Even small deviations in reproduction can cause the heating pattern to change, cycle times to increase, or process stability to deteriorate.
Key influencing factors include:
- position and shape of the windings
- distance between inductor and workpiece
- cross‑section and routing of the conductor
- position of the connections
- cooling and flow
- reproducible installation conditions
Benefits of inductor reproduction with INDUGO
Significantly lower costs
Reproduction is typically more cost‑effective than a spare part from the original manufacturer. This is especially true for older systems or special tools, where original parts can be disproportionately expensive.
Faster availability
Long lead times from the OEM often result in unnecessary downtime. Independent reproduction can help shorten production interruptions.
Replacement even for older or discontinued designs
If original parts are no longer available, inductor reproduction based on the original or on a sample provides a robust alternative.
Custom adaptation possible
A 1:1 copy is not always ideal. When reproducing custom inductors, geometry, cooling, or installation conditions can be adapted to current requirements.

FAQ on inductor reproduction
The most common questions at a glance.
What is the difference between inductor reproduction and inductor repair?
In inductor repair, an existing defect on the current component is remedied. In inductor reproduction, an inductor is manufactured entirely or largely anew – usually based on a sample, a drawing, or technical specifications.
Can an inductor be reproduced even if no drawing is available?
Yes. In many cases, inductor reproduction based on a sample is possible even without a complete drawing, provided that an old part or sufficient technical information is available.
Is reproduction also suitable for older systems?
Yes. In fact, for older or discontinued systems, inductor reproduction for existing equipment is often particularly relevant.
Are custom inductors also manufactured?
Yes. In addition to reconstructing existing components, custom inductors and tailor‑made inductors can also be produced for new applications.
Is reproduction cheaper than an original part?
In many cases, yes. Inductor reproduction can be more cost‑effective than purchasing directly from the manufacturer, especially when OEM prices are high or delivery times are long.
Can water‑cooled inductors be reproduced?
Yes. The reproduction of water‑cooled inductors is possible. It requires a high level of precision in geometry, connection technology, and cooling design.
What does inductor reproduction cost?
The costs cannot be stated as a flat rate, as they depend on the type and complexity of the inductor, the availability of drawings, and many other factors. Get in touch and we will be happy to prepare a non‑binding quotation for you.
