Feeding of the nickel-based alloys CZ-100, M-35-1, and CW-12MW, as well as of the austenitic stainless steel CN-7M, is investigated, using a combination of casting experiments and simulation. Casting trials are performed at five foundries, to produce a total of 55 plates of varying lengths and radiographic soundness levels. In order to develop the property databases necessary to simulate the ca...

Castings produced for the automotive industry are considered important components for overall roadworthiness. To ensure the safety of construction, it is necessary to check every part thoroughly using non-destructive testing. Radioscopy rapidly became the accepted way for controlling the quality of die cast pieces. In this paper the fundamental principles of the automated detection of casting d...

This chapter presents the application of a neural network to the industrial process modeling of high-pressure die casting (HPDC). The large number of interand intradependent process parameters makes it difficult to obtain an accurate physical model of the HPDC process that is paramount to understanding the effects of process parameters on casting defects such as porosity. The first stage of the...

One of the research directions this study is to determine possibility making precise, thin-walled castings from selected iron alloys. The scope work aimed at determining applicability casting process alloys with technology wax pattern, for precise a wall thickness less than 3 mm. article presents results tests carried out experimental shape steps, characterized by different thicknesses: 1 mm, 5...

The paper deals with a numerical modelling of equiaxed microstructure formation during the solidification of two-component alloys. The basic enthalpy formulation was applied to model the solidification. The equiaxed grain size was dependent on the average cooling velocity at the moment when the liquid metal reaches the liquidus temperature. The experimentally determined dependence between grain...

The article presents an analysis of the formation parameters microrelief artistic casting. direction for solving particular issues improving castings quality with high requirements accuracy surface relief is shown.

Within the manufacturing process planning, blanks are either selected or designed, respectively forms of input material for the manufacture of products. Reviewed in this paper are three types of group blanks: group castings, group forgings manufactured by closed die forging and free forging, and group blanks manufactured by pressing melted metal in casts. The paper also presents requisites for ...
