Co-Injection Analysis Services
Co-Injection provides an invaluable tool for simulating the process where a skin material is injected first, followed by the injection of a different core material. Co-Injection is the ideal process for using recycled materials or achieving specialized cosmetic and structural objectives.
Results of a Co-Injection study can determine the following:
The pattern of two co-injected materials to aid in part design and gate placement
The extent of penetration of the core material in relation to the skin material
The injection pressure and clamp force requirements for molding machine selection
The best transition point for switching from skin-material to core-material injection
Optimal inlet melt temperatures for skin and core materials
Thickness fraction of polymer B shows what percentage of the wall is occupied by the second polymer for co-injection. This plot shows the penetration about halfway through the filling process.
