Re: Rubber Matt has Hazy Areas
Thanks Chris, and Nemanja,
Yes, Chris, you got the gate location correct!, tunnel gated, and looks ample in size, (if not too big. )
We did dry the material, and I thought that was unnecessary, only because we usually don't dry TPE. but I am NOT the expert on this stuff! I might try different drying levels as you guys suggested.
I didn't see anything much in the mold, I would clean the mold, and next shot looked the same. Playing with fill speed, I could move the hazy spots around a bit, and diminish a bit, but always in the same basic location.
I ended up going Sloooow thru gate, then FAST the rest , or the gate would also look crappy. I can't remember doing parts at 50% full, I probably did(?), but I like that idea, and will look again.
FYI - I also cut off the ribs on the back of the part, stuck them in the mold, and shot again, thinking I had at least the problem (Turbulence flowing over the ribs) clarified, but those next parts looked the same too!....
Thanks for the feedback!
Joel
