Comprehensive Guide to Injection Molding Defects

Injection molding is a versatile and widely used manufacturing process, but like any production method, it can encounter defects. Understanding and addressing these injection molding defects is crucial to ensuring high-quality, reliable products. At DTG Injection Molding, we specialize in identifying, preventing, and solving common injection molding defects to deliver flawless results.

Common Injection Molding Defects and Solutions

1. Sink Marks
   • Description: Indentations on the surface of the part, often due to cooling issues.
   • Prevention: Optimize cooling times, adjust mold temperature, and ensure uniform wall thickness.
2. Warping
   • Description: Distortion or bending of the part after cooling, caused by uneven shrinkage.
   • Prevention: Use consistent cooling rates, ensure uniform wall thickness, and choose appropriate materials.
3. Flash
   • Description: Excess material that escapes from the mold cavity, forming a thin layer on the part’s edges.
   • Prevention: Maintain proper mold clamping force, ensure accurate mold alignment, and use precise mold dimensions.
4. Short Shots
   • Description: Incomplete filling of the mold cavity, resulting in missing sections or incomplete parts.
   • Prevention: Increase injection pressure, adjust mold temperature, and ensure proper material flow.
5. Burn Marks
   • Description: Discoloration or burn marks on the part’s surface, often caused by trapped air or excessive heating.
   • Prevention: Optimize venting, reduce injection speed, and monitor mold temperature closely.
6. Flow Lines
   • Description: Visible lines or patterns on the part’s surface, usually caused by variations in material flow.
   • Prevention: Adjust injection speed and pressure, ensure consistent mold temperature, and use suitable gate locations.
