Learning nugget: Sand-related defects
SUMMARY:
Casting defects are deviations, imperfections, or deficiencies in parts relative to the quality specifications established by the service requirement and design. Most of these defects originate from process deviations. Sand-related defects can be grouped into four main types: surface defects, defects due to sand expansion, mold-related defects, and defects related to the mold-metal reaction. Although virtually all sand-related defects can be avoided with proper sand mill management, studying them and understanding their origin is considered extremely useful for detecting their presence and taking the necessary corrective actions to eliminate them without incurring high process costs.

(*) This training session on sand-related defects is part of the “Introduction to Iron Casting” training series, which consists of 13 short videos lasting between 15 and 40 minutes.
Language:
English (soon)
Target audience:
- Technical and non-technical staff of iron foundry companies.
- New hires.
“The Foundry of the Future is that of connected processes that is able to take advantage of the knowledge generated inside the company at the same time that it keeps learning from its manufacturing and market experience.
Along with a deep knowledge of metallurgy, Industry 4.0 technologies, advanced data management systems and machine learning technologies have landed in this industry to transform the way castings are conceived”.
