In my earlier posts, we have looked at ways to control sand compactability and how it is affected by process variables. The next important control variable in a green sand system is clay level. It is vital to understand the science behind clay for efficient production.
In conversation with the Director of Contact Gearing Limited (UK), Graham Penning— the gear guru who got into the industry by chance and carved a niche for himself in the past four decades.
With more than two decades of working experience in the manufacturing industry, Vice President of Magna Electro Castings Limited, Mal Murugan, shares his experience with THORS training.
“Wait, what did you say?”
I was lost yet again. It was the early days of writing the Polymer Fundamentals course, and I had no idea what we were talking about.
“Polyethylene Terephthalate,” my expert, Kevin, patiently replied.
One day, I thought to myself, I was going to be able to say that name and, if lucky, be able to spell it. On that distant day, far out on the edge of near impossibility, I would be a genius who would have mastered the concept of polymers and their chemistry. But the world of polymers was foreign and utterly daunting. I slowly typed out the words, missing letters and looking to Kevin, who spelled the name out for me, again.

With over twenty years of work experience in the Human Resources sector, Jennifer Connelly from Fuserashi International Technology (FIT) is constantly reinventing her training methods to hire and retain the best talent in the manufacturing industry.
We told you how you can control the compactability of sand in our earlier blog. We are now back with tips to help you make better decisions during sand storage,transportation, testing, and handling.
What is Compactability?
Compactability relates to the reduction in volume of sand bonded with clay and water after undergoing compression applied by squeezing or compaction.
What is the ideal range for compactability?
Compactability should ideally lie in the range of 36-42.
Why is it important?
Compactability plays an important role in producing good quality molds and castings. It affects sand fill and mold density in the pockets of pattern. It also affects the integrity of mold edges and corners.
