There are several different types two color machine, then how to choose the suitable one for your bi material injection??

Well, the first let’s talk about the turnable (table rotary) machine with two parallel injection units, it is suit for the most 2k plastic housewares! And 280T will be ok for the max. 300mm part dimension!

Then customer may tell that they do not want the rotary table, as the machine cost will be much higher than without the table ones! If so, and you still want to run it in 2k automatically, then a transfert robot will be needed!

You’ll need the robot to pick the first color part, and put it again into the second color’s position, to have it second color injection! And by this way, then no problem the second nozzle is on the vertical side, L side or just upward the first nozzle, we can do the mold custom to fit with your machine!

The next let’s talk about the axis rotary (shaft rotary) machine, it is suit for the plastic parts which have both sides double colored, for example the toothbrushes!

And I’ll share more details in my next blog about the toothbrush making machine!

Hope it will help you!
