Abstract
The results of estimation of home scrap addition in charge influence on durability and wear of casting instrumentation life in the highpressure
casting technology using the hot chamber machine of alloy of AZ91 are presented. The wear of the following elements of the
casting instrumentation so-called "casting set" as: syphon, plunger, sliding-rings, nozzle and injection moulding nozzle was estimated.
A wear was estimated quantitative by registering the number of mould injections for different charges to the moment of element damage
supervision. A damage had to be at such level that liquidated an element from further exploitation and necessary was an exchange on new
or regeneration. In a final result allowed it the detailed determination of durability of the applied rigging elements in dependence on the
type of the applied type of melt. It is noticed, that together with the increase of home-scrap participation in the charge wear of pressure
machine instrumentation elements increases.
