When you are using a dual injector on your blending block if you have some of the hot plastic on the one side and went to the blending block and go ahead and inject your going to have a mass I would assume that something like that happen to you you have to make up for sure that it's still in the injector before you put it in the blending block. when I used the dual injector the temperature for never even because I used two different microwaves but they are plenty hot when I go ahead and shoot I had that incident happened to me the other day where we had some bleed over what that was my fault like I told you a little bit of one color got into the blending block and then I went ahead and injected so what little burnt to the other color you can be off 9° one way or the other when you are shooting the dual injector on both of the cups that you are using. using a laminate plate you shouldn't have any problems just to mention on the half that you are going to shoot the hot plastic on his cold right. but like I told you I'm sure you got some of the plastic up one side of that dual injector into your blending block. in what blending block or I should say dual injector are you using.
