The basics of injection molding What is a injection molding? How does it work and what is it used for? In this section, we answer these questions and show you common examples of injection molded parts to help you familiarize yourself with the basic mechanics and applications of the technolog...
Injection Molding Machine Components Process Plastic injection molding uses thermoplastic pellets, which need to be melted first. These are fed into the hopper and make their way to the barrel, where the reciprocating screw pulls back to make room for them to get through. The screw then goes fo...
Calculating The True Per Part Cost For Injection Molding Vs 3D Printing October 14, 2024 by Maya Posch 45 Comments At what point does it make sense to 3D print a part compared to opting for injection molding? The short answer is “it depends.” The medium-sized answer is, “it depends...

molds. Some advantages of injection molding are high tolerance precision, repeatability, large material selection, low labor cost, minimal scrap losses, and little need to finish parts after molding. Some disadvantages of this process are an expensive upfront tooling investment and process limitations....
During the plastic molding process, melted plastic is injected into a prefabricated mold under pressure. The pressurized plastic is forced into every crevice and then allowed to cool into the desired shape. Injection molding creates products with a smooth, clean finish that requires little to no ad...
