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.

MME Group, a Seaway Plastics Company has extensive experience in two-shot injection molding. We offer comprehensive tooling and secondary operations, serving diverse industries like medical, aerospace, industrial, and defense. MME Group specializes in plastic and LSR injection molding, providing a full suite of services from in-house tooling to post-molding operations, including assembly, kitting, and packaging. Our capabilities in two-shot molding allow us to create parts that combine different thermoplastics in a single cycle, improving design and functionality while cutting down on the need for post-molding assembly. This process is highly efficient and economical for high-volume production, ensuring the delivery of high-quality, multi-material components.

Two-shot injection molding, also known as dual-shot or multi-shot molding, is an advanced manufacturing process that enables the production of complex, multi-material components in a single molding cycle. This technique involves injecting two different thermoplastics, which can vary in color, type, or hardness, into a single mold sequentially. The process utilizes a specialized machine equipped with two barrels that inject the materials into the mold cavities one after the other, allowing for the creation of integrated, multi-functional parts.

While both two-shot injection molding and overmolding involve combining multiple materials to create a single part, they have key distinctions:

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

“We received the charger base and I want you all to know it looks FANTASTIC! Thank you for getting us this one for the BOD meeting.”

Two-shot injection molding is versatile and finds applications across various industries such as automotive, industrial, consumer, aerospace, defense, and particularly in the medical field, including:

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.

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:
