About Us


Dakota Molding has been in the rotational molding business since 1996. Our company is one of the largest custom molders in the Midwest. We specialize in both short-run and volume production using linear low density polyethylene, high density cross-linked polyethylene and Nylon 6 plastic resins. Operating out of our state-of the art facility Dakota Molding provides products well suited for Industrial, recreational, merchandising, safety and home use.

Rotational molding is a process ideally suited to producing hollow plastic products. By using additional post-molding operations, complex components can be produced enabling the process to compete effectively with other molding and extrusion practices. Rotational molding differs from other processing methods in that the heating, melting, shaping, and cooling stages all occur after the polymer is placed in the mould, therefore no external pressure is applied during forming. This provides the following advantages:
  • Economically produced large products
  • Minimum design constraints
  • Very low residual stresses
  • No polymer weld lines
