We offer a wide range of plastic enclosures for electronic devices and electrical applications
We are a company with more than 50 years of experience in the design, manufacture, customization, and worldwide distribution of plastic enclosures for encapsulating electronics.
Our designs are our own, cutting-edge, and adhere to the highest quality standards. We can sell you our products directly and ship them from Spain to anywhere in the world. Or if you prefer, you can contact our international distributor or your nearest electronics store.
Our entire supply and production chain is located in Europe, and we have quality controls certified to the ISO 9001:2015 standard. All our products comply with the RoHS2 Directive 2011/65/EU.
- Our highly qualified technical team specializes in customizing enclosures, both ours and those from other manufacturers.
We are dedicated to adapting each enclosure to meet your specific needs, whether aesthetic or functional, through CNC machining, UV digital printing, adhesive front panels, membrane keypads, injection molding with special materials and colors,... Our goal is to provide customization services that not only meet your technical requirements, but also give your product a professional, cutting-edge look. - Our expert engineers, thanks to their extensive experience designing hundreds of plastic enclosures, also offer the possibility of custom-designing enclosures for our customers.
We take care of every stage of the process: from the initial enclosure design to the technical development and the manufacture of the injection mold. In addition, we can optionally handle the injection molding of the enclosures, guaranteeing fast delivery times and the ability to adapt to your volume requirements. By managing the entire process in-house, we avoid additional costs associated with third parties, which allows us to offer this service at a competitive price without compromising quality.

History
Supertronic is a family business, now in its third generation, founded in 1971 in Barcelona (Spain). In its early days it manufactured electronic kits to build simple electronic devices (transistor, buzzer, etc.) for electronics enthusiasts. We soon identified the demand for versatile enclosures to protect electronics and began marketing them independently. Over time, we evolved toward the exclusive manufacture of enclosures, both plastic and metal, and a wide range of accessories.
During the 80s and 90s, we stopped producing kits to focus on enclosures and accessories, expanding our product range and establishing an international distribution network, especially throughout the countries of the European Union.
In the new millennium, we focused on export and customization, including machining and stamping services. Over the last decade, we have specialized exclusively in plastic enclosures and expanded customization services: digital printing, adhesive front panels and membrane keyboards, lacquering, etc.
Currently, we specialize in providing a complete solution for the encapsulation of our customers’ electronics, primarily with our enclosures but occasionally also using housings from other manufacturers, to achieve the most optimal result so that our customers only have to focus on adding value to their product and selling.
Environment
A healthy, livable environment is a shared commitment. At Supertronic, we take our environmental responsibility seriously.
We have implemented sustainable initiatives, such as a 100% electric vehicle fleet and all of our lighting based on LED technology. In addition, we have installed a system of solar panels and batteries that generates 80% of the energy we consume, reaffirming our commitment to renewable energy.
Our designers and engineers prioritize the use of eco-friendly materials that minimize environmental impact, ensuring that our natural resources – water, soil, and air – are preserved for future generations. This is reflected in the fact that all our products comply with strict environmental regulations such as REACH and RoHS, guaranteeing not only their quality but also their sustainability.
At Supertronic, we understand that protecting the environment is a collective task, and we are committed to leading by example, integrating sustainable practices into every aspect of our operation.
