Method of producing an injection moulding tool

An injection moulding tool which contains several injection points (3) which are fed simultaneously has a hot runner (2) located in a composite body. The composite body is composed of several plates (9, 11, 12, 13, 9') into which both the hot runner system (2) and the tubular heaters (10) requi...

Zusammenfassung:	An injection moulding tool which contains several injection points (3) which are fed simultaneously has a hot runner (2) located in a composite body. The composite body is composed of several plates (9, 11, 12, 13, 9') into which both the hot runner system (2) and the tubular heaters (10) required for the heating are worked from the parting surfaces (F1, F2, F3, F4), whereupon the individual surfaces, after appropriate pretreatment, are joined together by diffusion welding.
