YUEYI Mold, China top multi component mold maker, quality offer 2 component toothbrush mold shaft rotary injection molding, overmolding TPE brush, 2K rubber mold brush, toothbrush two color mold design!
As we all know, if you prefer to have the toothbrush mold automatic running, then must the injection machine itself equipped with the shaft rotating structure, or shaft rotation in the mold!!! Compared these two, suggest to have the former one, as by this way, the mold construction design will be much more easier also the brush mold cost will be cheaper than the latter. For example, 4+4cav adult toothbrush mold cost is USD28,000, while USD33,500 for the shaft rotation in the mold! But if your two color machine even has no ejector in the center to eject the axis rotary in the mold, then the cost may be over 50% higher than USD28,000.
Or otherwise, over molding will be your best solution, with automation robot system or manual hand to pick the first colored part and then put it into the second mold to have it double colored!
Pls do not hesitate to contact me for your toothbrush mold custom!
