How to Make Custom Electronic Enclosures
Electronic product developers are able to turn a scrapheap-bound piece of junk into a market-conquering phenomenon. Prototype and the end parts need custom electronic enclosures. The custom electronic enclosures represent the finishing touch of the electronic device and hold the components and wiring in place to make sure the electronic device is durable and have a professional appearance. At TEAM RAPID, our possibilities to make custom electronic enclosures are endless. We have ever use a wide range of processes and materials make laser-cut wooden box , sheet metal casing, CNC machined aluminum shell such as the enclosure of a MAC book laptop and more. Contact us today for your custom electronic enclosures projects. We will use different technologies like CNC machining, injection molding, sheet metal fabrication, pressure die casting and more to fulfill customers’ need.
Make Custom Electronic Enclosures
What is custom electronic enclosures
A custom electronic enclosure is a outer shell of electronic device. The electronic enclosure contains the components and other pars of the electronic device. Custom electronic enclosures are normally made from plastic or metal. The electronic enclosures keep components in place and protect the fragile components from external hazards such as dust and liquid. The electronic enclosures allow to connect inputs and outputs easily. It also makes the part recognizable though it shape, color, branding and more.
Manufacturing Processes for Custom Electronic Enclosures
3D Printing Custom Electronic Enclosures
3D printing is one of the best and efficient solution to create custom electronic enclosures in plastic and metal, it is especially good for prototyping and low-volume production. It allows complex designs, undercuts, and rapid design changes to be produced directly from CAD data without tooling investment. 3D-printed enclosures materials can be ABS-like resins and nylon, it can be used for fit, function, and early performance testing. While not ideal for high-volume production, 3D printing is an excellent choice for fast development, customization, and bridge manufacturing before mass production.
CNC machining custom electronics enclosures
CNC machines are one of the tools to make custom electronics enclosure. CNC machining centers can metal and plastic. The parts can be produced directly from a digital CAD design. CNC machining is repeatable. Once one custom electronics enclosure is machined, the same design file can be sued to produce thousand more identical copies. CNC machining allows to make complex enclosures with high geometrical complex. CNC machining allow to make smooth curves, asymmetrical structures and complex features. CNC machining may be slower than other methods like sheet metal fabrication, but it is an effective method to produce custom electronic enclosures
Sheet metal fabrication custom electronics enclosures
Sheet metal fabrication is one of the most important methods to create custom electronic enclosures. Sheet metal fabrication enclosures are affordable and durable. They are widely used on product such as desktop computer, indoor and outdoor industrial applications. Sheet metal fabrication is a ideal method to make custom electronics enclosure. A sheet of metal can be turned into an open-ended box. When the holes are punched and stamped into the box, the functional custom electronic enclosures are on the way. Aluminum, steel and stainless steel are the common used metals to create custom electronic enclosures. And depending on the application, a wide range of finishes can be added.
Injection molding custom electronics enclosures
Injection molding is a great method to mass produce simple consumer products. It can also used to create plastic parts in large quantities. Injection molding is widely used to produce handheld controller, sensors, electronic key, display and more. Injection molding can be used with hard thermoplastic like ABS, acrylic, aceta and non-rigid plastics like TPV and TPE which has shock absorption.
Pressure die casting custom electronics enclosures
Pressure die casting a a quick, reliable and cost-effective producing process to produce custom electronic enclosures with tight tolerances in high volume. Pressure die casting process consists of injecting under high pressure a molten metal alloy into a steel mold which gets solidified quickly to form a part. It is then automatically extracted. Compared to other processes, the cost of pressure die casting is lower. Pressure die casting is economical, thousand to million of parts can be produced before requiring replacement. Pressure die casting custom electronics enclosures has close dimensional control and great surface finish. Pressure die casting custom electronics enclosures have thin walls and are lightweight.
Plastic Electronic Enclosure vs. Metal Electronic Enclosure
Choosing the right material for your custom electronic enclosure is important, it relates with many factors, the best choice not means the good performance, but also reduce budget and friendly to environment. There are plastic and metal offer distinct here:
| Feature | Plastic Electronic Enclosure | Metal Electronic Enclosure |
|---|---|---|
| Common Materials | ABS, Polycarbonate (PC), PC-ABS | Aluminum, Steel, Stainless Steel |
| Weight | Lightweight, ideal for portable devices | Heavier, better for fixed or industrial use |
| Strength & Durability | Moderate strength, suitable for light to medium-duty use | High strength and impact resistance |
| Design Flexibility | Excellent – complex shapes, snap-fits, bosses can be molded | Limited – shape depends on cutting, bending, and welding |
| Electrical Insulation | Naturally non-conductive, no grounding required | Conductive – grounding is required |
| Heat Dissipation | Limited heat resistance and thermal performance | Excellent thermal conductivity |
| EMI / RFI Shielding | Not inherent, requires conductive coating or inserts | Inherent EMI/RFI shielding |
| Corrosion Resistance | Excellent, no rust | Requires coating or corrosion-resistant alloys |
| Surface Finish & Appearance | Color molded-in, smooth cosmetic finish | Anodizing, powder coating, plating available |
| Manufacturing Cost | Lower tooling and part cost for many applications | Higher material and fabrication cost |
| Production Methods | Injection molding, CNC machining, 3D printing | Sheet metal fabrication, CNC machining |
| Typical Applications | Consumer electronics, medical housings, IoT devices | Industrial equipment, outdoor electronics, power systems |
