7" Press Tonnage

[2043]

Hey Everybody,

I have been looking at different pressing options and was wondering the following:

It seems that the press tonnage for 12" records generally falls in the 100-125 ton range for manual presses like Hamiltons and Finebilts for example. I think 3 post Alpha brochure shows 108 tons.

So for 7" records would a 50-80 ton press be appropriate? It's not often I see one and when I do the nameplates are difficult to read.

It seems like less mass to press would take less force. Not sure if it's a ratio or what. I'm horrible with physics...

Thanks in advance for knowledge sharing.

You're on the right track, Toolex AD12 12"press is 108 tonnes. Toolex also made a smaller press, the AD7 for 7" records, as did Lened.I don't know the tonnage of these dedicated 7" presses but they are certainly less. I would think there is no point in making a dedicated 7" press these days - probably best to make one press that can make 7", 10" and 12" records.
