Customized Injection Plastic Shell for Digital Electronic

• PCB mounting points: standoffs and bosses that match the holes on the circuit board.
•  
• Apertures: specific holes for screens (displays), buttons, ports (USB-C), speakers, microphones, and cameras. Usually made via additional processing such as CNC machining or laser cutting.
•  
• EMI/RFI shielding: can include channels for inserting conductive gaskets or places for the metalized plating/shield cans (EMI/RFI protection).
•  
• Thermal management: vents, thermal pads, or places of contact with the heat sinks.
•  
• Cosmetic finishes: texture (to prevent fingerprints), high gloss, matte, in-mold labeling (IML) or painting.

Why Injection Molding is the Go-To Process for Electronic Shells

1. High Volume & Low Cost: With the expensive mold already made, each individual unit produced afterwards will be very inexpensive, ideal for electronics that come out in large volumes of tens or hundreds of thousands of units.
2. Precision & Consistency: Molds make components with very fine tolerances, ensuring that each unit fits their internal components such as PCBs, batteries, and screens properly.
3. Good Surface Finishing: Produces a finished surface right from the mold itself, with anything from a textured grip to a glossy surface.
4. Versatility with Materials: A variety of materials can be utilized to satisfy any needs (refer below).
5. Features Built-in: Snap fits, complex shapes, living hinges, screw bosses, ribs and many more features can be built in a single shot.
