There are several ways to molding 2 color flip top closures: by rotary table multi component injection machine, which needs machine with turntable.
So any other way to molding such flip top by standard machine ?
Sure, but still needs second unit side entry beside the machine, check below picture.
And what will be the mold structure ?
Have to use hydraulic cylinder core pulling, after first color inject, cylinder work to cut off first color overflow into second color area, also after core pulling, then second unit inject. Motor can not replace cylinder here, as motor just keep on rotating, can not realize the limit effect, to prevent first color overflow.
In additionally, mold needs valve gate injection, to realize raw material timing control.
Or there is other way, mold without cylinder if your standard machine no hydraulic core pulling installed: we do the custom the turntable, to good fit with machine to realize rotating.
Feel free to contact for quality two color molds custom.
