Abstract

Inventia se refera la o forma de turnare, destinata pieselor cu forma complicata si care necesita miezuri ale caror diametre sînt mai mari decît diametrul gurii de scoatere a miezului din piesa turnata. Extragerea miezului se realizeaza prin tragerea unor stifturi, cu ajutorul carora piesele ce alcatuiesc miezul se pot demonta. Fiecare reper al miezului are gabaritul mai mic decît diametrul gurii de scoatere a miezului.
