Notes

Knit (Weld) lines are “caused by the melt-front flowing around an object standing proud in a plastic part as well as at the end of fill where the melt-front comes together again. Can be minimized or eliminated with a mold-flow study when the mold is in design phase. Once the mold is made and the gate is placed, one can minimize this flaw only by changing the melt and the mold temperature.” (Wikipedia, Knit Lines or Weld Lines, 4/25/2012)
