Injection molding and CNC machining are used to manufacture tools for several applications in the electronics industry. Our high-precision tooling and molding services help produce components with complex geometries that define many electronic devices and systems.   

The final parts our molds can help you with include knobs, fuse boxes, switch components, circuit boards, computer parts, sensors, phone accessories, toasters, coffee machines, microwaves, kitchen appliances, and telecommunication equipment.   Here are some examples fabricated by Polmold designed-and-made injection mold tooling:

Plastic Injection Molded Components

• High-Performance Polymer Capacitors: Utilizing polymers as the dielectric material, these capacitors offer superior stability, lower equivalent series resistance (ESR), and higher tolerance to temperature and voltage compared to traditional electrolytic capacitors. They are widely used in power supply circuits, automotive electronics, and high-frequency applications.
• Connectors, Insulators and Sockets: PPS and LCPs are used in high-density connectors and sockets for their excellent electrical properties, resistance to high temperatures, and mechanical strength. These are essential in environments where reliability and precision are critical, such as in telecommunications and aerospace.
• Polyether Ether Ketone (PEEK) Components: Known for its high temperature resistance, mechanical strength, and chemical resistance, PEEK is used in high-performance parts like insulators, bushings, and connectors in aerospace, automotive, and medical electronics.

Metal Injection Molded (MIM) Components

• Heat Sinks and Cooling Fins: Made from aluminum, copper, or alloys, these components are essential for dissipating heat in power electronics, CPUs, GPUs, and LED lighting. Their efficiency in cooling improves the performance and lifespan of electronic devices.
• Shielding Components: Metal shields are used to protect sensitive electronics from electromagnetic interference (EMI) and radio frequency interference (RFI). Materials like copper, aluminum, and mu-metal are used to fabricate cases, enclosures, and shields for mobile phones, computers, and medical equipment.

These plastic and metal components highlight the importance of materials science and precision engineering in the development of advanced electronics. They are selected for their unique properties that meet the demands of specific applications, enhancing the functionality, reliability, and performance of electronic devices.
