Mould Flow Analysis
Mold Flow Analysis (MFA) is a computer simulation process used in plastic injection molding to predict how molten plastic will flow inside a mold. This helps identify defects, optimize designs, and improve manufacturing efficiency.
Common Injection Molding Defects, Causes, and Solutions
| Defect | Cause | Solution |
|---|---|---|
| Short Shot | Incomplete filling | Increase injection pressure or temperature |
| Weld Lines | Two flow fronts meeting | Optimize gate locations & flow balance |
| Air Traps | Air gets trapped in mold | Add vents or modify flow paths |
| Sink Marks | Uneven cooling & shrinkage | Adjust cooling time & gate placement |
| Warping | Uneven material shrinkage | Optimize cooling system & part geometry |
