What is injection molding?

Injection molding is a standard process in plastic manufacturing for manufacturing miniature medical device connectors. The basic idea is to heat solid plastic pellets until they’re molten, then forcefully inject them into specialized molds. Inside the mold, the molten plastic fills the cavity and cools and solidifies, ultimately forming the required Pogo Pin connectors.

Key steps of the injection molding process:

1. Material Preparation:

  • Selecting medical-grade plastic materials suitable for use in medical devices and preparing them in pellet or powder form.

2. Heating and Melting:

  • Placing plastic pellets into the injection molding machine’s heating barrel. Melting them into a molten state through heating and mixing.
