mold construction design for core toggle multi shot molding

Leave a comment

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 platen multi shot molding

Leave a comment

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 !

Many customers complain that our mold cost is very high, but pls let me expain why:

As we all know, mold price can be different 100% due mainly to his details,

steel quality, mold construction design, machining way, cooling system, hot runner system…. and so on.

  • Steel quality: We use the real quality steel, not like most mold makers here in China are cheating in steel! Then customers may tell that they can ask the supplier to provide the steel certificate to prove it is the right steel they’ll use. Well, I’ll keep silence about this, anyway, unless you trust that supplier very well, otherwise do not believe even they provide you the certificate!
  • Mold construction design: Except the steel quality, mold construction is the key that we insist to have the molds with excellent performance! That’s why we pay much more attention on it to make the mold durable and easy maintenance! Pls contact me for the details, I would love to share you our two color mold design!
  • Machining way: Some experienced customers may ask the supplier to share the details break up of mold cost, but honestly speaking, it can only clearly show you the steel cost & hot runner cost, for the key machining cost still will be a big problem. As we all know, CNC machines have many different levels according to their precision work. So the machining cost will be corresponding differ a lot. And for us, we ensure you to use the high speed CNC to reach 0.02mm precision!
  • Hot runner system: Well, for customers who know Huangyan market very well, then they should know the Huangyan local brand hot runner system is only cost 500RMB per tip, but ours is USD750 per tip! Compared to the traditional heaters is circled around the nozzle body, ours is more stable working as heaters are all inserted into the nozzle body! Design is just similar as YUDO!

In additionally, all the spare parts we use, is brand imported, for example JunFan cylinder from Taiwan,  Japan Daido springs and Korea Samsol springs, etc. Just to avoid some stupid mistakes happen!

So what we offer you is the quality mold with very reasonable cost!

Anyway, if you’re looking for the durable mold with easy maintenance, pls feel free to contact with me! We’ll offer the best to invite your first order to see what we can do for you!
