🧩 What Are Plastic Injection Parts?
Plastic injection parts are created by melting plastic pellets and injecting them into molds. Once cooled, they form precise, ready-to-use components.

In electronics, these parts are commonly used as:
- Device housing/enclosures
- PCB mounts and supports
- Buttons, switches, and control panels
- Connectors and wire holders
- Plugs and access panel covers

🔌 Key Functions in Electronics

● Precision Assembly and Integration
Injection molding enables the production of highly detailed components — such as USB ports, screw holes, and sensor mounts — in one piece, streamlining assembly.

● Natural Electrical Insulation
Most plastics are non-conductive, providing excellent insulation and reducing the risk of short circuits when used near electronic circuits.

● Multi-Functionality in One Part
Plastic parts can be designed to perform multiple functions, such as structural support, mechanical interaction, and airflow management — all in one, reducing part count and cost.

● Shock and Vibration Absorption
Some plastics offer inherent flexibility that acts as shock absorbers, protecting sensitive electronics from mechanical stress.

🛠️ Common Plastics for Electronics Applications

● ABS (Acrylonitrile Butadiene Styrene)
Tough, impact-resistant, and easy to mold. Ideal for durable enclosures like remote control casings and control boxes.

● PC (Polycarbonate)
High transparency and excellent heat resistance. Used in light-transmitting parts like display covers and transparent control panels.

● PBT/PC Blends
Combines flame resistance from PBT with PC’s toughness. Suitable for power adapters, electrical connectors, and circuit boxes.

● PPS (Polyphenylene Sulfide)
Excellent heat and chemical resistance. Used near heat sources such as power supplies, heating connectors, and high-performance assemblies.

📐 Design Considerations for Injection Molded Parts

- Shrinkage Rates:
Each plastic type shrinks differently; CAD designs must account for final dimensions after cooling.

- Parting Lines:
Impacts visual finish and dimensional accuracy. Must be strategically placed during mold design.

- Structural Reinforcements (Ribs, Bosses):
Adds strength without increasing wall thickness, reducing material use and cycle time.

- Screw Boss Design:
Must withstand fastening stress without cracking over time.

- Draft Angles:
Necessary for easy part ejection from molds without damage.
