Small Part Injection Molding

Discover AIM Processing's customer small part injection molding services, designed to deliver precise, high-quality components for industries requiring intricate and complex plastic parts.


AIM Processing specializes in small part plastic injection molding. We define "small plastic parts" as roughly the size of your fingernail to the size of your hand. Injection molding is a process in which plastic resin, in pellet form, is heated and sheared until it reaches a viscous state.

It is then injected under enormous pressure into a steel or aluminum mold, cooled until it hardens, and ejected. With small part injection molding, we are able to manufacture complex, small shapes in a cost-effective, repeatable process.

As a leading small plastic parts manufacturer, we work with engineering grade plastics to create custom molded plastic parts that match the requirements for a part with properties like: chemical resistance, flexural strength, durometer, and yield strength to name a few. There are so many material options, and we can help you make the right choice for your program.

Understanding Plastic Injection Molding

The design and manufacture of custom molded plastic parts can seem simple at first, but there are many details that must be taken into consideration depending on how the part will be used. For example, there are mechanical properties like:

  • Strength of the plastic part
  • Yield
  • Stress concentration

Material properties, such as:

  • Chemical resistance
  • Lubricity
  • Hardness
  • Shrinkage
  • Cost

And, cosmetic aspects like:

  • Texture
  • Polish
  • Clarity

Then there are factors like the manufacturability of gate locations, draft, and ejector pins. It's enough to make your head spin.
