All About Plaster Mold CastingWhat it is and How it Works

Casting is a type of metal fabrication process in which molten metal is poured into the cavity of a specially designed mold and allowed to harden After the metal workpiece hardens it is removed from the die to undergo various finishing treatments or for use as a final product Casting methods are typically used to create intricate solid shapes and cast products are found in a wide range of

UV VIS SpectroscopyChemical Analysis

The wavelength and amount of light that a compound absorbs depends on its molecular structure and the concentration of the compound used Concentration dependence follows Beer s Law A=εbc A = log T bc A = is absorbance no units since A = log P 0 P ε= the molar absorbtivity with units of L mol 1 cm 1

Compound castingless weight greater cost effectiveness

One variant which is becoming ever more important in series production is compound casting Through the combination of various materials this compound casting process can help components meet the most diverse of requirements And with the hybrid construction process the material bond is created by recastingseparate hot or cold bonding/jointing processes are not necessary This in turn reduces the number of production steps needed in the manufacturing process A good example of applications in this field is the manufacturing of engine blocks As a pure sheet steel solution it consists of numerous individual parts which are joined to one another In contrast the compound casting solution makes it possible to produce this component as a single piece The intelligently designed casting made from an aluminium or magnesium alloy ensures the high functional integrity of flanges and bearing carriers for instance In difficult areas a carefully positioned insert such as a semi finished product made of steel or an aluminium alloy provides the necessary strength In comparison with conventional diecasting the manufacture of a compound casting
