Figure 3. A case study of EP moulds with an integrated sandwich chamber for the fluid flow. One-half of the mould has been sectioned to highlight the reduced volume of the process chamber and the presence of the lattice structure. The external side of the moulded part measures 150 mm in length. EP: Expanded polymer.
