Rotational Molding Engineering

Design & Engineering Services

Beginning a new project starts with a solid design concept. Our in-house Design & Engineering Department will help advise and manage your project all the way to a produced rototmolded part.

Whether your project is a rough idea or a 3D model, we believe in developing a partnership early on with the customer and strive to reduce lead times and so both parties benefit from rotational molding.

Rotational Molding Design Guides

Rotational Molding design guides

  • Minimum wall separation 5x wall thickness (a)
  • Minimum wall separation 3x wall thickness (b)
  • Uniform wall thickness ± 20% (c)
  • ±10% is considered precise tolerance (c)
  • Wall thickness .090" to 1.00" (c)
  • Different wall thickness can be produced based on functional requirements
  • Large flat areas need a crown or ribs (d)
  • Corners need minimum radius of 3/16"(e)
  • Structural strength
  • Reinforcing ribs - average proportions
  • Height 4x wall thickness (f)
  • Width 5x wall thickness (g)
  • Kiss-off ribbing (h)
  • Part Finishing and Secondary Operations

Note: Design Guide information is based on Linear Low Density Polyethylene (LLDPE) other materials tolerance can vary.
