We have some problem with an article that we produce after the injection process.
We produce an transparent white shade (for a lamp article) and the material from each we make it is PPHO + white masterbatch (concentration 25%, we mix with 1% from the PPHO quantity).
The color is ok, the material is ok, the only problem is that because need to be transparent to see the light from the bulb, inside the material is has shadows marks or the material was not completely homogenized or melt correctly.
What do you think is the problem the masterbatch or the equipment parameters?
