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.
Above is machine with turntable, also two parallel injection units.
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.
