2K – a double injection molding or bi-injection
Bi-Injection & 2K injection is one of the variants producing a two-color / material part without using the two-stage rotation molding method. Two materials are injected independently via two independent gates into a single cavity in a more or less defined configuration. Except for the reduced cycle time, another benefit of using bi-injection molding is the better adhesion of the two materials at the junction, mostly due to the better molecular penetration at higher temperature.
The challenge of designing the co-injection process is the selection of gate location, and the processing condition. This is because the material interface of the two materials is solely governed by the melt flow pattern.

2K – Recommended operating conditions
In order to improve the adhesion between the polymers, we recommend the following:
High temperatures of both polymers
High injection speed
Mould temperature> 60 ° C
holding pressures not too high
avoid suck injection pressure as high as possible
Pre-essicamaneto of hygroscopic materials (moisture absorbing)
Pre-heating omogeneeo of the engineering plastic (Ideal temperature of 100 ° C) dry, clean and smooth polymer.
sufficient thickness on the side of the softer polymer
Venting of the mold
Location and profile of the injection properly studied
Desired object is manufacturable using 2k-injection, it is definitely best to use 2k-injection over traditional injection molding.

2k-injection a better approach are as followed:
•lower cost
•higher-quality product
•significant reduction in assembly operations
•reduction in cycle times
