mold construction design for rotary shaft multi shot molding

In my previous blog, we’ve talked about the mold construction design for rotary platen multi shot molding, so here I’ll continue to share you my understanding for the rotary shaft molding.

Rotary shaft multi shot molding

The rotary shaft multi shot molding is similar to the rotary platen molding, and adding additional capabilities: The rotating platen can now be retracted from the core half. In addition, the cavities and cores of each stage have different geometries. Axis rotating performs switching between different core / cavity sets.

And it is common used in 2 component toothbrush molding!
Check below video for better understanding:

The rotary shaft 2k molding is more complex than the rotary platen 2k molding, and it requires a more complex mold construction design. This complexity further increases the 2k mold cost and delivery time, but it allows for the production of more complex multi component molded parts.

If you’re still looking for the good two materials mold maker in China, then we can be your another good choice.

TPE toothbrush mold

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!
