Every time I watch one of these guys in the Third World sand casting I learn a few things. The skill and speed of this molder is impressive. His use of two “chopsticks” as drawspikes is cool. I also see he uses two small alignment pins (like I commonly use when appropriate) not the typical long pins we see. Denis
That mold with the multi piece pattern in a four piece flask is really impressive, I don't think most of us would consider attempting something like that and they make it look easy. Sidenote: it doesn't matter how many times I see videos like that, I still can't get me head around wearing flip flops in a foundry.
I'm amazed at the sand not dropping out of those thin flask sections. Although no one walked on their molds, bare feet seem to serve some of those squatting molders pretty effectively. I'm with you on the furnace guys though.
I've seen more of these Indian (or Pakistani ?) molding videos. Those guys are excellent and have more knowledge and experience than many of us. It is a shame that those have barely safety equipment (unprotected eyes near a furnace or pouring) and are paid so badly, a few dollars a day when they are lucky.
This video is a little different than most, here they seem to be using "normal" greensand rather than the molasses sand you see in most of the aluminum casting videos. I'd take it a little further and say they have more experience than ANY of us.
It would be interesting to know for how many decades this pattern has been cast at this foundry. Did he learn from a master, maybe his father? Doing this pattern all day long day after day is physically punishing. Somehow the process is refined to near perfection. Denis
