Abstract
Uno stampo per lo stampaggio di materie plastiche per mezzo di un procedimento in cui il calore necessario viene apportato alla materia plastica in corso di stampaggio per mezzo dell'applicazione di un campo elettromagnetico, che è principalmente costituito da un materiale non elettricamente conduttivo nel quale sono incorporati uno o più organi conduttivi per il campo elettromagnetico, disposti e profilati per guidare il campo elettromagnetico in modo tale da produrre nelle regioni attive di stampaggio una distribuzione sostanzialmente uniforme delle linee di campo e dell'intensità del campo elettromagnetico. Questi organi conduttivi possono avere sostanzialmente la sola funzione di rendere uniforme il campo elettromagnetico in corrispondenza delle regioni di stampaggio, oppure possono avere anche, o solamente, la funzione di concentrare il campo elettromagnetico in corrispondenza delle rimanenti regioni. Se nello stampo sono presenti inserti metallici o presentanti parti conduttive, questi possono essere utilizzati per costituire alcuni degli organi conduttivi incorporati nello stampo ai fini indicati.
