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 !

bi materials pediatric medium concentration oxygen mask

Leave a comment

 

YUEYI Mold, China top bi component mold maker, offer paediatric oxygen mask injection mold 2k, two material aerosol pediatric mask, plastic padiatrics medical mask 2 color!

Various groups have questioned the use of PVC in medical products and it’s impact on the environment. So now we change to use PP+TPE materials to reduce the environmental impact of its products and processes.

The utilisation of new materials and the latest manufacturing technology has resulted in the elimination of PVC from the mask shell resulting in a reduced environmental impact！

  1. Soft face seal
    For improved patient comfort
  2. A choice of “under chin” or “on-chin” positions
    Provides a better fit on a wider range of patient face shapes
  3. Incurved nose seal
    Improving the fit and eliminating the need for a separate nose clip.
    Designed to prevent oxygen or aerosolised drugs entering the patients’ eyes!
  4. The material forming the body of the mask is clear, permitting visualisation of the patients’ nose and lips. It is also rigid enough to maintain the mask’s shape during transportation and use!

medium concentration pediatric oxygen mask provides a comfortable lightweight option.

If you’re still looking for the good two color pediatric mask mold maker in China, then I’m sure we can be your another good choice.

tpe n pp nebulizer mask

YUEYI Mold, China top dual material mold maker, offer tpe n pp nebulizer mask, 2 component aerosol face mask, plastic oxygen mask injection mould 2k, double gas mask mold!

In order to make it comfortable for the patient, we do the unique masks design:

–   A soft, thermoplastic elastomeric, face seal ensures a greater level of patient comfort.

–   An incurved nose seal designed to prevent oxygen entering the patient’s eyes. This eliminates the need for a separate metal nose clip making the product MRI compatible.

–   The unique nose seal is designed to equalise the pressure exerted on the nose as the seal conforms to differing nose shapes.

–   These design features combine to provide an improved seal on the patient’s face, which in turn, results in higher oxygen concentrations as less ambient air enters the mask.

–   The mask retaining elastic can be fitted either above or below the patient’s ears depending on the patient’s face shape. In the “below ear” position it eliminates the discomfort and longer-term trauma created by elastic to the top of the patient’s ears.

–   A choice of “under chin” or “on chin” positions provides a better fit on a wider range of patient face shapes.

–   The material forming the body of the mask is clear, permitting visualisation of the patient’s nose and lips. It is also rigid enough to maintain the mask’s shape during transportation and use!
