Manufacturing of rotational production mould is one of the new activities within TRIPLAST.


The production comprises of the following phases:


  • The client’s order for engineering of the mould
  • Analysis of the proposed final product in relation with rotational moulding constraints
  • Analysis of technical specifications and product governing standards – should they exist
  • Engineering of the intended mould and presentation of the 3D concept for the client
  • Brainstorming of the project with the client
  • Engineering and prototyping of the finite element
  • Analysis of parting lines in preparation of mould production
  • Verification/enhancement/improvement of the mould
  • Project approval
  • Mould execution
  • Test production and adjustments to the mould


What materials are used to produce the moulds?

The moulds are executed using steel or aluminium.


What wall thickness can be executed in rotational formation?

Depending on the product’s load bearing requirements, wall thickness can vary from 2-3mm to 15mm.


What is the difference between moulds executed of steel and aluminium regarding product quality?

The selection between steel and aluminium is mainly determined by the product geometry and surface finish requirements.


When does rotational formation become feasible?

In comparison with other production techniques, rotational formation becomes feasible (or even the single option), when the product size and/or geometry becomes impractical or cost inefficient to be executed by other techniques, such as blow-moulding, or injection.
