Knit Lines
#1
I'm concerned about back pressure. I need resin flows to merge correctly while still hot. Knit lines are a real pain to control. Will Porcerax II solve that problem?

Thanks in advance.

Knit lines are cause by gas being trapped between the two converging material fronts. The longer it the takes for the material to flow together the colder the material will be and the weaker the knit line will be. Inserting Porcerax II so it extends, approximately .250" either side of the knit line will allow the gases to pass thru the Porcerax II and the material fronts will flow together quickly. The hotter the material is when the two fronts meet the them more the material will be able to meld together forming a stronger and less noticeable the knit line.
