Top-10 Injection Molding Defects And How To Fix Them

Flow Lines.Description Flow lines are streaks,patterns,or lines - commonly off-toned in color - that show up on the prototype part as a consequence of the physical path and cooling profile of the molten plastic as it flows into the injection mold tooling cavity.Injection molded plastic begins its journey through the part tooling via an entry section called a gate.The Identification and Prevention of Defects on Finished defects may originate in the substrate metal as a result of the thermo-mechanical fabrication process used to produce the sheet or extrusion or during handling and storage of the material before finishing.Defects can also result from a lack of control,or contamination,of the solutions used in the various stages used to produce an anodized Taking Subjectivity out of Class A Surface Evaluation Aug 03,2008 What are the defects in the production of SAPH310 automotive structural steel#0183;As automotive companies get smaller,design and release engineers are more likely to choose materials in which they have high confidence.The more closely molders can match the appearance of steel,the more likely it is that program teams will be open to specifying composites in place of steel, says Fernholz.
