Sink Marks\n* **Definition**: \"Depressions or craters on a part's surface caused by internal material shrinkage as it cools.\"\n* **Potential Causes**: [\"Excessively thick wall/rib sections\", \"Insufficient holding pressure or time\", \"Melt or mold temperature is too high\", \"Inadequate cooling time\"]\n* **Recommended Resolutions**: [\"Reduce the thickness of the thickest sections\", \"Increase holding pressure and/or time\", \"Lower mold/melt temperature\", \"Increase cooling time before ejection\"]\n\n### 2. Knit Lines (Weld Lines)\n* **Definition**: \"A visible line or seam where two or more fronts of molten plastic have met and failed to fuse completely.\"\n* **Potential Causes**: [\"Part geometry has holes or obstructions\", \"Material or mold temperature is too low\", \"Low injection speed or pressure\"]\n* **Recommended Resolutions**: [\"Increase material and/or mold temperature\", \"Increase injection speed and/or pressure\", \"Relocate the gate to alter flow paths\", \"Add an overflow well at the weld location\"]\n\n### 3.
