What color injection?

Color injection molding, that is a plastic product with two colors. Take the keys on the phone to give you an example shows that the key is black, and the number "5" is transparent.
There are two concrete implementations:
1, two-color injection molding mold by two-color injection molding machine.
The mold of the mold 2, there are two front mold. (Two front mold structure is basically the same.) Injection molding machine after the installation of two parallel installation site after mold, mold installation before mounting two before mold. Color injection molding machine has two radio Tsui (two barrel), supporting two dryers, two kinds of molding material.
Injection molding process:
The first co-production, the emergence of digital post-mold of transparent material, "5." After the mold is opened, after the mold is rotated 180 degrees. (That is, position 2 after molding swap the) second co-production, the black material fired into the mold cavity, surrounded by the number "5" after the open mode, you can see the two colors of the keys.

2, due to the two-color injection molding machine machine more expensive, many companies use another approach.
Like to open two sets of mold, the process is as follows:
The first use of a general injection molding machine, the transparent product number "5" to do it, then the transparent product "5" into another set of black mold in the injection molding material. This is also the color of the product came out. Belong to two molding.
