Plastic Enclosures

We design and manufacture custom plastic enclosures so that you don’t compromise on the design or quality of your project.  Our bespoke plastic boxes offer great value for money. Plus you can enjoy rapid turnaround times, no mould tool costs, better aesthetics and no restrictions on changes or quantity

Plastic is an increasingly popular material choice for enclosures and casings. Generally it is lighter, more durable and more cost effective than metal alternatives.  We stock a wide range of plastic materials including recycled, UL94-V0 listed grades, ABS, HIPS, Polycarbonates, Acrylics, and Carbon Fibre effect.

Speak to CDT, the plastic enclosure experts. We do everything from PCB electronics casings, to DIN rail units and IP-rated or weatherproofed boxes.


Do not settle for a standard off-the-shelf plastic box

With over 30 years experience, we work in partnership with you to create a casing or enclosure that fits your specific requirements.

Here at Custom Design Technologies Ltd (CDT), formerly known as Bafbox, our expert team of designers, engineers and manufacturing operatives make the complex simple. We love sharing our enclosure knowledge so that ‘things’ work better. We excel at transforming flat pieces of plastic into bespoke quality boxes, enclosures, plates and cases.
