Deltron Enclosures specialises in the design and manufacture of electronic enclosures for a wide variety of industries and applications. To complement our extensive range of enclosure options, we can manage your project from concept to production with our in-house machining, painting and enclosure assembly services.

Our customer portfolio is broad, and consists of small and medium original equipment manufacturers, wholesalers, catalogue distributors and multi-national blue-chip companies, some of which we have worked with for over 50 years, others have joined us more recently.


Why work with us?

 > As part of the Alpha 3 Manufacturing group, we have a lot to offer.
Purchase your enclosures from us and we can machine them in-house, paint the enclosures in any colour, assemble the enclosures with components we have sourced ourselves and send them out to you ready for immediate termination. That way, you don’t have to deal with a long supply chain; saving time and money.

As part of the Alpha 3 Manufacturing group, we also manufacture cable assemblies and EMC filters should you require these additional components for your project.

 > A knowledgeable sales and engineering team.
Our teams have had experience in the industry and worked with us for many years, enabling them to offer engineering advice and support to help you find the best product for your requirements. Even if enclosures are outside your area of expertise, our teams can help you understand the relevant terminology and what they mean for your project if you are unsure.

 > Effective Communication.
We allocate an operations assistant to all customers, who becomes the key contact for queries and updates throughout the process.


Our History

In the early days we started out in Acton, West London, where, as Deltron Components Limited, we manufactured die cast boxes and professional audio connectors for over 50 years, before relocating to North Lincolnshire in 2000.

Our original die cast boxes have stood the test of time and are still available today along with newer ranges of IP rated enclosures, heavy duty enclosures, plastic enclosures, plus a corrosion and impact resistant range.

Deltron Enclosures is now one of the four brands of DEM Manufacturing which includes Roxburgh EMC, Deltron Components and BES.

Since 2007, DEM Manufacturing has been a division of Alpha 3 Manufacturing Limited which also includes CCS Electronics, CTL Manufacturing and Tekdata Interconnections; electromechanical sub-contract manufacturers. All sites are UK based, currently employing 290 people.
