    Quality Issues with Valve Gate running PC/ABS w/FR

    Struggling quite a bit with a couple molds that are valve-gated running PC/ABS w/FR. I cannot run the valve-gate temperatures at the recommended temps. without delamination, gate blush or halo appearance. But, running the temps. so low is causing leakage between the valve-gate components.

    I would take any advise anyone has, but also would like to know what experiences you have had with PC/ABS FR in valve-gate systems. I'd also like to know if there are better or worse valve-gate manufactures out there. I'm not going to mention who built this one though given we have not determined to be supplier specific.
