I have seen this condition with Sub-gates, The surface area where the sub-gates pulled required additional polish to remove rough surfaces that would flake while as the mold
opened or during ejection. Not knowing what type gating your mold has I suggested this as a starting point.
Hi Brian,
Yes it is a sub gate. and a brand new mold. I will check it out.
Thank you,
Nicholas
I have seen it before from the runner, part, or cold slug well dragging on the way out causing it to leave flakes on the mold.
I agree, check your parts and runner for drag marks, a tell tell sign for the issue you describe.
