mold construction design for core toggle multi shot molding

We have discussed the rotary table multi shot mold and rotary shaft multi shot mold before, so today we will talk about the two-color injection of the core toggle mold!

The core toggle multi shot molding process is the easiest, because the core and cavity of the mold do not need to be moved. Conversely, changing the geometry of the mold cavity by moving the slider. Check below pictures:

First inject material A into the cavity, at the same time the slider is in the fully extended position!

Then retracting the slider to reveal a new portion of the cavity!

After that, material B is injected into the reconfigured cavity through a separate gate (above the middle nozzle), the remaining gap is filled by moving the slider!

Then the plastic part hardens and ejected from the mold. Sequentially circulated as the above to continue the molding!

Adding a slider to the mold adds the cost of the tool, but it still can be much more cheaper than rotating platen or rotary shaft mold. Unfortunately, it can not produce the complex multi colored plastic parts.

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.
