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

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

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