Over 50 years providing the best solution for electronics encapsulation

Since its founding in 1971 in Barcelona, Supertronic has walked an impressive path, evolving from a third-generation family business to a leader in the design, manufacture, and customization of plastic cases for electronic assemblies. With over 50 years of experience, our mission has always been to offer complete solutions for the encapsulation of electronics, adapting to the changing needs of the market and our clients.

Our story began with the manufacture of electronic kits, where we quickly identified the demand for versatile and quality plastic cases. This insight led us to specialize in the manufacturing of cases, first as part of the kits and later as standalone products, meeting the specific demands of the market.

In the 1980s, we focused exclusively on manufacturing plastic and metal cases, complementing our offering with a line of accessories. The 1990s marked our international expansion, thanks to our participation in fairs and the creation of distributor networks throughout Europe.

With the turn of the millennium, we prioritized exporting and diversifying our range of enclosures, emphasizing our plastic cases over the metal ones. Customization became a key pillar, offering services like machining, printing, and the manufacture of adhesive faceplates and membrane keyboards.

Today, Supertronic is synonymous with quality and customization in the electronic assemblies sector. Our completely local production guarantees immediate delivery and superior quality. We offer a wide range of cases, from IP65 versions to fireproof ones, with a wide variety of accessories.

Our commitment to the environment is firm, with a fleet of electric vehicles and a solar energy system backing our operation. With the ISO:9001.2015 certification, we ensure that each product meets the highest standards.

Looking towards the future, Supertronic focuses on providing global solutions for electronics encapsulation, optimizing internal processes, and leveraging new technologies, always with the goal of enabling our clients to focus on what they do best: innovate and sell their products.
