Injection molded plastic parts

How Does Injection Molding Work?

Injection molding works by melting plastic resin and injecting it under high pressure into a precision-machined mold cavity. Once the material cools and solidifies, the mold opens and the finished part is ejected. This process enables fast, repeatable production of complex plastic parts with tight tolerances and consistent quality.
