Need Help Troubleshooting Defects...

[moldingppm]

Hi All.

I'm having an issue with some ABS parts. It looks like I'm getting some gate blush and possible stress marks on these parts. Can anyone help me troubleshoot this? I've played with injection pressure, speed, and temps. The "blush" comes and goes, I'm assuming it might be not mixing well with the base ABS.

The lines around the part I can't get to go away at all. I'm assuming it's stress, but I'm not sure. This is a brand new mold from China that my customer delivered and said "here run this."

Any thoughts? Pictures attached.

Thanks
