how to choose the suitable injection machine for your 2k toothbrush molding?

Here I’ll share with you some info about the axis rotary (shaft rotary) machine, it is suit for the plastic parts which have both sides double colored, for example the toothbrushes! There are also several ways to have the molded brushes:

  • by axis rotary machine + normal 2k toothbrush mold
  • by normal 2k machine +  2k brush mold with in mold rotary system
  • table rotary machine + 2k brush mold with in mold rotary system
  • two molds injection by over molding (insert molding)

What is axis rotary machine?? On the machine moving platen should equipped with below structure, together with the center axis, below the red marked axis in picture two, to eject the center insert and turn it 180° to shift the first color part to the second color!

Then what’s the difference between the normal 2k brush mold & in mold rotary?? Well, here the normal 2k brush mold means, the injection machine has the structure or system to drive the red center axis directly! If no, then we have to make the center axis rotate in the mold, we’ll use a rack system which will be driven by hydraulic cylinder, to drive to rotate the center axis!

Anyway, if you’re still looking for the good bi material brush mold maker in China, then we can be your another good choice!

Mold name: tear drop toothbrush 2 component

Material: PCTG+TPE

Product dimension: 17.1 X 192 X 14mm

Product weight: first color 11g, second color 4g

Steel: core/cavity German S420 with hardness HRC45-48

Cavity: 12+12cav

Gate: 24 tips YUDO valve gate

Mold dimension: 626.8 X 1237.3 X 1010.2mm

Mold weight: 1718kg

Machine: Engel 250T two color injection machine

There are three ways to manufacture the 2 component brush handles:

  • One is by overmolding, it will needs two molds injection, run by the normal single color injection machine.
  • Second is two color mold + shaft rotary two color machine
  • While the third is two color brush in mold rotary + normal two color machine.

As we all know the first one, so here let’s talk about the second & third ones!

If we go ahead with the second, then it needs the machine should be equipped with the shaft rotary structure! At the same time, needs double injection nozzles! Check below pics:

But the two color mold will be relatively easier than the third way! As by the third, will need the toothbrush in mold rotary, i.e. no need the machine have the shaft rotary structure (but sure needs double injection nozzles), it will complete the rotary in the mold.

Above all, by the second, the two color mold will be easier, but the machine is more complex; while by the third, the mold is much more complex, but the machine easier!!!

If you’re still looking for the good toothbrush mold maker in China, we can be your another good choice. We’ll do the custom based on your factory manufacturing situation!

TPE toothbrush mold

Focare Mould, China top multi component mold maker, quality offer 2 component toothbrush mold shaft rotary injection molding, overmolding TPE brush, 2K rubber mold brush, toothbrush two color mold design!

As we all know, if you prefer to have the toothbrush mold automatic running, then must the injection machine itself equipped with the shaft rotating structure, or shaft rotation in the mold!!! Compared these two, suggest to have the former one, as by this way, the mold construction design will be much more easier also the brush mold cost will be cheaper than the latter. For example, 4+4cav adult toothbrush mold cost is USD28,000, while USD33,500 for the shaft rotation in the mold! But if your two color machine even has no ejector in the center to eject the axis rotary in the mold, then the cost may be over 50% higher than USD28,000.

Or otherwise, over molding will be your best solution, with automation robot system or manual hand to pick the first colored part and then put it into the second mold to have it double colored!

Pls do not hesitate to contact me for your toothbrush mold custom!
