Short Shot in Injection Molding: A Defect Crime Scene

In this injection molding defect case file, an incomplete plastic part becomes a crime scene. The technician tries to fix the short shot by increasing injection pressure and adjusting molding parameters. But the real cause may come from poor venting, a restrictive runner system, uneven wall thickness, or flow path problems. When the root cause is ignored, one defect can quickly create another — flash. Before cutting steel, DFM review, mold design evaluation, material behavior analysis, and molding feasibility checks can help reduce short shot, flash, scrap, and production cost.
