Mad Moose Baits Posted November 11, 2017 Report Share Posted November 11, 2017 I am building my own centrifugal casting setup. 12" molds. My question is on the mold ring/can: for a 12"x1" how much does the "lip" on the lid of the can go into the cavity? It looks like about 1/4" to me. I have a local machine shop that can make me a can for a fraction of what I would pay for "the real thing". The parts being cast are spinnerbaits and buzzbaits, so a 1" mold should do the trick. My plan is to put mold in place and then the lid using large CClamps to add the pressure. I look forward to the replies and thank you in advance. Oh ....I am going DIY due to limited funds and let's face it, if we weren't DIY types we wouldn't be here. Quote Link to comment Share on other sites More sharing options...

dlaery Posted November 11, 2017 Report Share Posted November 11, 2017 mine has no lip. Just 2 round flat aluminum disks. the important part is getting the mold in the center of the mold. I guess if you have a lip a 1/4' tall on the bottom disk then the mold would fit in and then that would keep the mold in the center. Quote Link to comment Share on other sites More sharing options...

This is the frame to make (vulcanize) the mold, not the part that spins the mold and you pour the lead in. We may be talking about two different things Quote Link to comment Share on other sites More sharing options...

dlaery Posted November 11, 2017 Report Share Posted November 11, 2017 i guess i was wrong, it is 1/4" tall. Quote Link to comment Share on other sites More sharing options...
Mad Moose Baits Posted November 11, 2017 Author Report Share Posted November 11, 2017 Just now, dlaery said: i guess i was wrong, it is 1/4" tall. So I am clear: the interior of the can is 1" so the mold rubber is compressed by that 1/4" disc part of the lid? Quote Link to comment Share on other sites More sharing options...

dlaery Posted November 11, 2017 Report Share Posted November 11, 2017 this is what I have been taught, during vulcanizing, if the lid touches the 1 inch frame, then the mold may not vulcanize properly. meaning it didn't get enough pressure to squeeze the rubber to fill in all of the detail leaving a bad spot in a cavity. My frame is taller and I put in a 1/2" spacer disk on top of the mold, so I can may a 1-1/2" thick mold if necessary. I went and checked the lip on the bottom and found out I measured the bottom disk when I told you 1/4 inch the bottom disk has a 1/4 in lip and the top has 1/2 inch.

Mad Moose Baits Posted November 11, 2017 Author Report Share Posted November 11, 2017 Ok that is very very helpful. The main mold ring looks to be about 1 3/4" high and the bottom piece goes 1/4" reducing the depth to 1 1/2" the spacer allows for the mold to be 1" and then the top lid compresses it all. Thanks a ton dlaery! Quote Link to comment Share on other sites More sharing options...
