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.
