Common injection molding defects and how to fix them:

<ol>
<li>Warping — uneven cooling → balance mold temperature</li>
<li>Sink marks — insufficient packing → increase hold pressure/time</li>
<li>Flash — low clamp force or mold fit → increase tonnage or repair parting line</li>
<li>Short shot — low injection speed or material temp → increase both</li>
<li>Weld lines — cold melt front → increase mold temp and injection speed</li>
</ol>
