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:

double injection core toggle mold design

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 platen multi shot molding

In the past, a multi materials part was done by using additional secondary services or more complex assemblies. However, today’s multi materials injection molding largely eliminates these additional requirements, making it much more easier to manufacture complex finished parts, faster and cheaper.

According to moving different molded parts can be divided into:

1.      Rotary platen multi shot molding

2.      Rotary shaft multi shot molding

3.      Core toggle multi shot molding

Rotary Platen Multi Shot Molding

The mold core plate contains two identical cores that are mirrored on the centerline of the platen and coincide with the axis of rotation. The cavity plate connected to the fixed platen contains two cavities with different geometries. In each cycle, the rotary platen completes the switching of the molded parts, and eliminates the need for manual switching.

Check below video for better understanding!

Here we only show the two materials mold, which can actually accommodate more materials. The rotary platen can be rotated by 90°, 120° or 180° depending on the amount of material used. Also it will need a special injection machine to provide the required rotation on the core side.

And on my next blogs, I’ll share you my understanding of mold construction design for Rotary shaft multi shot molding & Core toggle multi shot molding!

Hope it will help you for your multi materials molding !

double bottom wine glass plastic injection mold

此幻灯片需要JavaScript支持。

How to have the double bottom tumblers? Well, the most common one is glasses, and it is welded by glue with ultrasound, thus to have the appearance that the middle of the two glasses looks hollow!

But as we all know that glass is very fragile, so can we use plastic instead of glass, but still retaining the hollow style in the middle of the two glasses? The answer is yes!

With the efforts of our genius team, we have developed an innovative mold construction design. We canceled the ultrasound welding method in the secondary stage, directly by plastic injecting in one step, to have exactly the same glass as above pictures showed – double bottom wine glass in plastic, also it can be 2k or 3k !

Now the mold is under making, and we plan to show it on Chinaplast 2020, together with Yizumi 3 color machine!

Focare invites you to bring us your 2k mold / 3k mold project big or small, and you will receive full support right from the design stage to prototyping and commercial launch of your product.

Focare provides full support through an experienced part design team that has done a huge number of different multi shot applications.

how to choose the suitable two color machine for your bi material molding ??

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!
