I often shake my head when I see centrifugal molding for soft baits and the numbers of people that think its the next big thing. The large volume producers don't use it for a reason. 1- you don't get an even distribution of flake (as evidenced in the above video at the end with all the flake bunched up at the tail). 2- for the same reasons as 1 you can't run salt or any other weight additive as it will get pushed to the out side edge of the mold. 3- There is no way to consistently produce laminates. 4- Time, in the same amount of time it took to load the mold in the centrifuge, pour the baits and then cool and open the mold, I and several others I know could have shot 3 times as many baits by hand, all while being able to produce laminates, use higher loads of glitter and added salt or other additives if needed.
No, in artificial stone you don't get the same finish, unless you lubricate the molds the baits tend to stick in the molds and they don't handle the heat anywhere near as good as aluminum.
