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.

We YUEYI Mold, China top multi injection mold maker, always here ready to service you, if you’re still looking for the good multi shot mold maker in China!

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 !

co injection stack mold supply

co injection stack mold China supply

Co injection molds is widely used in food and medical packaging, and we YUEYI provides co injection tooling based on innovated technology and systems – CO INJECTION STACK MOLD supply!

Co-injection stack mold can effectively solve the low output of customers’ two-color molded parts, greatly increase the production and reduce the consumption costs!

While compared to the single layer two color mold, the clamping force of co-injection stack mold will be 1.2-1.5 times! And the molding cycle time will be very similar, but the output efficiency is more than 1.8 times!

So what should be paid attention while doing the co-injection stack mold??

  • co injection stack molding with robotic transfer or the mold core part rotary is ok!
  • The mold requires high machining accuracy and high concentricity
  • The mold construction design must consider a reasonable and dedicated mold base system, hot runner system, load guidance system, two-way ejection system, linkage secondary molding system, etc.

We YUEYI team has accumulated over ten years of R & D and manufacturing experience in multi material molding technology. Foreseeably design and correct defects for various two-color parts, and support customers with the mature bi material molding technologies!!

If you’re troubled with the low output of your current 2k molding, if you’re still looking for the good 2k mold maker in China, then we can be your another good choice!

YUEYI Mold, China top multi color mold maker, quality offer bicolors storage tray mold, plastic trays double mold, two shot collection tray, two color mould design storing tray!

2k molds and bi injection molding have grown significantly now. The advantages of applying 2k molding technology are not only considering to have a better surface looking of the plastic parts, but maybe also to enhance part design features, or simply to add quality to the part or to reduce the cost of the downstream parts assembly.

Two color injection is not specific to one technology. It is driven by product design and can be performed by different mold construction design techniques such as: internal pull-back core / sliders, rotating stripper plate, indexing transfer plate, turntable, and robot transfer from cavity to cavity or mold to mold.

We YUEYI provides rotary molds, cube molds, shuttle molds and in mold automation to efficiently perform multi-shot processes.

Welcome your new inquiry!
