Investment casting is one of the precise casting methods where disposable wax patterns
made in wax injection molds are used to make a casting mold. The production capacity of …

The paper presents the results of an investigation of the thermal deformation of moulding
sands with an inorganic (geopolymer) binder with a relaxation additive, whose main task is …

An optical measurement test setup was used to determine the elastic modulus of chemically
bonded sand as it is used in foundry applications. The surface of the sand specimen was …

The paper refers to earlier publications of the author, on identification of properties of
thermomechanical, chemically hardened core/mold sands. In that earlier period, first version …

The paper summarizes research realized by the author in laboratory and industrial
conditions (foundries of cast steel and cast iron, castings up to 50 tons) on the effects of the …

Binder jetting sand printing is a 3D printing process in which a sand mould or sand core is
produced from an STL file. A single layer of a sand matrix consisting of one or more grains of …

This chapter presents a practical approach to the identification and interpretation of
phenomena in multi-component ceramic granular porous materials (called mould sands) …

Simulation codes currently used in the foundry industry are primarily used to predict casting
quality, quality tied mainly to the location of defects such as shrinkage (voids of shrinkage …

This study is an attempt to determine by Hot Distortion Test (HDT) the impact of physical
methods of hardening inorganic binders in the moulding sands on phenomena caused by …

Spool control valves are one of the most common use components of fluid power systems.
They play an important role in hydraulic systems controlling flow direction and movement of …
