A study of the effects of digitally produced casting models on casting quality
Jewelry manufacturers are steadily integrating digitally produced casting models into their production processes, having a wide variety of machines and materials from which to choose. There is a significant body...
The effects of hot isostatic pressing of platinum alloy castings on mechanical properties and microstructures
In earlier research a better understanding of the solidification characteristics for a number of platinum-based alloys was established. The findings demonstrated a strong tendency...
Glossary: joining line
A welding is defined as brazing when it is made using a process temperature that is above 450°C (840°F) and below the items’ melting temperature. This is typical when using solders based on gold, silver, platinum or palladium.
MASTER ALLOY: an alloy produced in drop form that must be added to the fine metal (gold, silver or other precious metals) for the production of jewelry at title.
Gold and silver, used as pure metals, do not allow to obtain jewels that stand up under wear and tear,...
ALLOYS: PRODUCTION PROCESSES
Alloys for casting
Compositions characterized by an improved performance on:• metal flowability in liquid phase • increase of filling on complex shapes,• optimization of scraps reusage without problems,• minimization of solidification shrinkage.
AN ALLOY’S IDENTITY DOCUMENT
The quantity (in weight) of precious metal present in the final alloy, expressed as per thousand parts or carats. The characterization of an alloy is performed in dedicated title, since the ratio between metal and master...
