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

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.

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.

HDPE injection molding involves melting the HDPE material and injecting it into a mold cavity to create specific shapes.

Maintaining temperatures becomes a crucial process to ensure smooth flow and prevents material degradation during the HDPE injection molding process. You can maintain the temperatures between 180°C to 230°C to achieve the goal.
