As we find that more and customers are looking for a custom Raspberry Pi case, we thought it would be helpful to share these 3 things to consider before you approach your manufacturer.

So, if you are looking for an enclosure to either to hold a Raspberry Pi  or to include one with other components and/or configurations read on…


Planning makes the perfect Pi case

At the outset carefully plan out your case. Why not go old school and get a pencil and draw your case! Make sure you get an outline of it on all sides. This gives an idea of the components that need to be accommodated and connectors that will need openings.

This outline will provide a useful start to specifying your case. Then note things like the location of the Pi’s SoC, (overheating with prolonged use can occur so an opening for hot air to release is suggested) and spacing around cables and SD card to reach their destination, (for instance, the HDMI connector will need enough space around the port for the rubber moulding on mating cable).

Then what other hardware will you be hosting (camera, display, battery or RFID component etc). Where do these need to be in relation to the Pi? And what is the best placement / dimensions to accommodate these?

Understanding its purpose

As expert custom electronic case manufacturers we suggest you take time to fully understand what the current and future purpose of the project you’re working on is.

What special requirements are needed. Where, when, and who will be using it? Does it have brand, health and safety, weatherproofing or aesthetic considerations that need to be taken into account. Is weight, impact resistance or hygiene important? All these elements will inform the specification, in particular, the type of material you use.

The number of cases required, the type of material and the manufacturing method used are the main factors dictating the price per unit. Talk to a custom electronic case manufacturer, like CDT, who can provide information on the types of material and finishes available that suit your requirements.

Injection moulding vs custom plastic machining

For anything less than 10,000 custom plastic machining provides better cost efficiency compared to injection moulding. It does not need to use mould tools so there are no expensive moulds to produce or dies to cut.

Using our custom manufacturing process means modifications are easier and faster. It provides the greatest flexibility of design which is especially useful for prototype development and for marketplaces with ever-shortening product life-cycles.

Also, if precision of your custom plastic parts is important then plastic machining is often preferable. The telecommunications, aerospace and medical equipment sectors which tend to need the closest possible tolerances often choose plastic machining for its superior precision.

Lastly the types of plastic materials you can use for injection moulding is limited. Rubbers and other flexible materials are ideal for moulding; however, many harder, high-performance specialty plastics can only be machined. So, if you have a specific advanced plastic in mind for your electronic casing, do check it is a viable option for injection moulding.


In conclusion

So, if you don’t want to settle for an off-the-shelf Pi case and instead go for a custom Pi case we hope that this blog helps you enjoy a smoother, speedier turnaround of your Pi project.
