High Precision Injection Molded Heat Sink Housing 50-300mm
Durable high-precision OEM supplier of heat sink module housings for electronic devices.
Process Introduction
The heat sink module housing utilizes high-precision injection molding, often using materials such as ABS, PC+ABS, and PA+GF. These housings offer high strength, heat resistance, and dimensional stability, typically used in conjunction with metal heat sinks for securing, protection, and airflow control.
Process Flow
- Drying and pre-treatment of engineering plastics
- Injection molding to ensure uniform wall thickness
- Cooling and demolding to prevent warping
- Surface treatment (spraying, electroplating, anti-static coating)
- Dimensional inspection and assembly testing
