Insert Molding

1 step. Stronger parts.

Is insert molding right for your product?

Both insert molding and overmolding involve putting two types of materials together to make one part.

Insert molding, however, takes only one step, which makes for stronger parts and a more robust structure (compared to overmolding that requires two steps: one to create the substrate and one for the overmold that goes on top of it).

Advantages of Insert Molding:

  • Durability: Inserts will guarantee the function of threads and mitigate wear and tear over the part’s life.
  • Strength: Insert molding’s “one-shot” process can produce stronger parts than overmolding and other processes.
  • Part Production: Insert molding is great for creating prototypes and production parts.

Other design benefits of insert molding include the elimination of secondary assembly operations such as snap fits, gluing, and the use of screws or fasteners; reduction in the number of required parts; and integration of design features not possible by plastic alone.

Insert molding is frequently used in industries such as medical, packaging, automotive, consumer electronics, building/construction, and robotics.
