Common Problems and Solutions
Flow Lines:
- Challenge: Flow lines are common problems characterized by inconsistent flow of molten material that cause visible streaks on the surface of the finished product.
- Solution: I ensure that melt temperature is maintained consistently within the range of 280°C —300°C to deal with flow lines. Also, optimizing injection speed while ensuring a uniformly heated mold can make it smother and defect-free.
Warpage:
- Challenge: Warpage occurs when different parts of the mold contract at different rates as they cool, causing deformation.
- Solution: I prevent warpage by maintaining a mold temperature between 80°C and 100°C. Balanced cooling and controlling holding pressure and time also reduce internal stresses that lead to this problem.
Short Shots:
- Challenge: Short shots occur due to either insufficient pressure or poor material flow, which prevents the mold cavity from filling completely.
- Solution: To avoid shot shots, I raise injection pressure to between 1000 and 1500 bars, which should be enough to fill all cavities with force. Additionally, appropriate injection speed retention and thorough drying out of moisture-related materials prevent such a fault from happening.
Sink Marks:
- Challenge: The molded part’s surface often bears sink marks that appear as hollows due to the shrinkage of raw materials during the cooling process.
- Solution: Sink marks are prevented through optimizing mold temperature; as well as ensuring adequate holding pressure that will compensate for any material shrinkage. Cooling time is also increased for uniform solidification of material to be achieved before demolding
Burn Marks:
- Challenge: Burn marks usually result from excessive temperatures or long residence times within the barrel, which lead to feedstock degradation.
- Solution: In order not to have burn marks one has got always monitor and control melt temperature so it remains within 280oC–300oC respectively. I lower the rate at which injection goes into a mold if there is no sufficient venting.
