Plastic injection molding is a manufacturing process that converts raw plastic material—in granular or pellet form—into molded parts and products. During such operations, the injection molding machine melts and injects the plastic into pre-designed molds. After a cooling period, the hardened plastic part is ejected from the mold and proceeds to further finishing operations or direct use.

By leveraging plastic injection molding technology, industry professionals create a wide range of molded components suitable for use in a diverse set of industries. In particular, the process offers several advantages that make it well-suited for use in the production of electronic parts and products.

Why Use Plastic Injection Molding for Electronics?

The plastic injection molding process is commonly employed for the manufacture of electronics for a number of reasons. These include:

Greater cost-effectiveness

While the initial investment cost for building a plastic injection mold can be high, the costs for materials are typically much lower when compared to other manufacturing methods. The process is especially cost-effective for high volume production orders.

Better part and process consistency

From part to part and between production runs, the injection molding process produces more consistent.

Broader material options

Using plastics for injection molding operations opens up a wealth of material options to industry professionals. The injection molding process accommodates a wide range of plastics of varying formulations, colors, and finishes to suit different part and production needs, including flexible vs. rigid, conductive vs. non-conductive, watertight, UV resistant, and more.

Applications of Plastic Injection Molding in the Electronics Industry

Injection molding finds application in the manufacture of electronic parts and products for a variety of industries, such as aerospace, appliances, automotive, communications, construction, military and defense, and packaging. Some typical end uses of injection molded electronics include:

  • Cell phones
  • Computers
  • Electronic connectors
  • Housings
  • Laser printers
  • Maritime electronic systems
  • Meters, sensors, and other testing equipment
  • Semiconductor processing equipment
  • Telecommunications systems
