01 / SUBSTRUCTURE
Build a stable reference
Set the armature, base and datums before adding the foam core. The support must preserve the geometry while allowing access for clay application, machining and manual work.
TOOLING MATERIALSApplication / Automotive
Industrial clay gives vehicle designers a surface they can sculpt, machine and revise during shape development. The model combines a stable supporting structure with foam bulk and a clay working layer for surface evaluation.

Engineering requirements
01 / SUBSTRUCTURE
Set the armature, base and datums before adding the foam core. The support must preserve the geometry while allowing access for clay application, machining and manual work.
02 / WORKING SURFACE
Condition and apply the selected iClay grade according to its TDS. The clay layer supports CNC rough shaping and hand refinement, followed by scanning or surface review as required.
03 / MATERIAL CHOICE
Compare iClay 61M and iClay 61H using their handling instructions and the studio’s machining and finishing requirements. Foam and model boards serve as supporting materials rather than substitutes for the clay working layer.
04 / HANDOVER
Maintain reference points between the model, measuring equipment and CAD data. Repeated surface revisions belong to the styling process; a later rigid master is a separate tooling decision.
