Hi, I am working on a university project and am trying to find the best way to manufacture the part in the attached image out of aluminium if the product was put into production, but because of it's size I'm not sure what the best option would be, it would also be best if there was a hole running through it. I'm not sure if it would work but I read some information on slush casting but don't know much about, I don't actually have to get it made, just specify the process which would be used. If anyone could help it would be appreciated. Thanks in advance. Sam.
