Can customer use 2 color machine for 1 component mold ?

As we know to get two colored plastics, need two color machine with turntable or standard machine with second injection unit beside. Sure compared to the former, stand machine with second unit beside can be more flexible, to fit both molds for two color and single color.

Here is standard machine with second injection unit beside. Very flexible to move the second unit to mold 1 component or 2 component parts.

So how about the turntable machine ? Can customer use it for 1 component mold ?

The answer is yes, but should have two sets molds together manufacturing (two molds for different product OK), must ensure two molds’ height same, otherwise, long time manufacturing may cause machine plates deformation. Or customer only can use one mold, the second only is a dummy, and table must not turn. This can be adjusted by machine program setting.

After meet above conditions, the rest just ensure injection shot weight, etc. items fit, same as single color machine. Just for the existent molds, may need to do some re-machining of mold bottom plates to make it good fixed onto the machine.

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.
