When looking for custom electromagnets, comparing prices or lead times isn't enough.
The choice of supplier has a direct impact on the reliability of your automated system, the service life of the component and the stability of your production. An electromagnet designed for a specific application performs far better than a standard model. At Bobinados Osés, we develop fully personalised solutions, with no catalogue, manufactured under a quality management system certified to ISO 9001.

What a reliable custom electromagnet manufacturer should offer
Not every custom electromagnet manufacturer offers the same level of specialisation. A reliable supplier needs to bring engineering knowledge, design capability and repeatable manufacturing processes. The goal isn't just to produce a component, but to guarantee it performs correctly throughout its working life.
A specialised manufacturer should offer:
- Design adapted to the customer's application
- Full traceability of materials and processes
- Quality control throughout manufacturing
- Capacity to produce both prototypes and series runs
- Technical guidance from the design phase onwards
- Production of complete electromechanical subassemblies
At Bobinados Osés, we work with OEM manufacturers, industrial integrators, engineering departments and manufacturers of special machinery. Our team gets involved from the start of the project, turning a technical need into a solution ready for series production.
Beyond the electromagnet itself, we supply wiring, connectors, encapsulation, laser marking and final assemblies ready to integrate into the production line. Custom electromagnets built this way reduce assembly time, simplify logistics and improve process efficiency.
Custom-built vs standard catalogue electromagnets: why it matters
One of the most common mistakes when comparing electromagnet manufacturers is assuming that every electromagnet performs the same way. In reality, every application has different operating conditions and calls for a specific design.
The force and reliability of an electromagnet depend on variables such as:
- Duty cycle (ED%)
- Operating temperature
- Thermal dissipation through Joule heating
- Ferromagnetic core material
- Air gap between the electromagnet and the part
- Residual magnetism
- Current intensity
- Magnetic circuit geometry
When these variables aren't taken into account, the component can lose holding force, run hotter than expected or wear out sooner.
Residual magnetism is another key factor. After the current is switched off, part of the magnetic flux can remain in the core. If this isn't considered during design, the part may fail to release with precision, affecting the automated system.
Custom manufacturing also improves batch-to-batch repeatability and makes series production easier, which matters most to OEMs and industrial automation companies that need every installed component to behave the same way.
Does your application have requirements a catalogue can't cover? Tell us about your project and our technical team will assess the best solution for your process.
ISO 9001: the quality guarantee the industry demands
ISO 9001 certification isn't a legal requirement for manufacturing electromagnets in Spain or the EU. However, for many buyers it's an essential criterion during supplier approval.
At Bobinados Osés, we hold ISO 9001:2015 certification, audited by Bureau Veritas, covering the manufacture of electromagnetic coils, ferrite assemblies, electromechanical assemblies and laser marking. This guarantees our manufacturing processes are documented, audited and geared towards continuous improvement.
For an industrial buyer, working with a certified supplier means access to:
- Full material traceability
- Consistency between production batches
- Documented procedures
- Quality control throughout the process
- Lower risk of product incidents
Certified manufacturer vs manufacturer without ISO

| ISO 9001 certified supplier | Non-certified supplier |
|---|---|
| Audited processes | Variable internal procedures |
| Documented traceability | Weaker record control |
| Batch-to-batch consistency | Greater variability |
| Easier supplier approval | Can complicate approval processes |
| Higher confidence for OEM and industry | More uncertainty for the buyer |
Certification also brings legal and technical peace of mind. If any issue arises, documented traceability allows materials, checks and manufacturing records to be identified, reducing risk throughout the project's lifecycle.
Design-led manufacturing, no catalogue: how we work
At Bobinados Osés, we don't work from a standard product catalogue. Every project starts from the customer's technical requirements, developing a component adapted to their application. This optimises performance from the design phase and guarantees straightforward integration into the production process.
We mainly work with two types of projects.
Development from scratch
When a project is still at the engineering stage, we work with the customer's technical department to define the electromagnet's characteristics and validate its performance before manufacturing begins.
At Bobinados Osés, we work with OEM manufacturers, industrial integrators, engineering departments and manufacturers of special machinery.
Manufacturing to your drawing
Many customers already have complete technical drawings and specifications. In these cases, we manufacture exactly to that documentation, applying the same quality controls and traceability as any in-house development.
The result is a repeatable, stable component ready to integrate into the production line without modifications.
Beyond the electromagnet or the electromagnetic coil, we can supply the fully assembled subassembly, reducing assembly time, minimising integration errors and speeding up commissioning of new industrial equipment.
Key technical factors in an industrial electromagnet
Designing electromagnets for industrial automation involves much more than nominal force. Supply voltage, duty cycle (ED%), operating temperature, part geometry, IP protection rating and energy efficiency all play a role.
In advanced industrial applications, factors like magnetic reluctance, air gap and residual magnetism directly affect holding force and the repeatability of the automated system. Even small variations can alter how the electromagnetic system behaves.
Many automated systems also use PWM control to optimise energy consumption, reduce heating and improve operating stability during long duty cycles.
Frequently asked questions about custom electromagnet manufacturers
Is ISO 9001 certification mandatory for an electromagnet manufacturer?
No. ISO 9001 certification isn't a legal requirement for manufacturing electromagnets. However, for many OEMs, machinery manufacturers and publicly funded projects, it's a standard criterion during supplier approval.
What's the difference between a catalogue electromagnet and a custom-built one?
A catalogue electromagnet is designed for standard applications and average operating conditions. A custom-built electromagnet is calculated according to the required force, duty cycle, temperature, air gap and available space.
What information does a manufacturer need to design a custom electromagnet?
To develop a personalised solution, it's helpful to provide:
- Required force
- Supply voltage
- Expected duty cycle
- Ambient temperature
- Available space
- Maximum dimensions
- Technical drawings or specifications, if available
With this information, we can design custom electromagnets adapted to the real needs of the project and optimise their behaviour from the first stage of manufacturing.
