When forging process begins, defects are common problem experienced by manufacturers and forgers. TO overcome the issue, you should know about the right cause of problem and corrective measures to prevent the re-occurrences. Here, we will discuss on forging defects in brief and corrective measure how to overcome the same.

- There are few cases when actual forging takes place only at the surface and does not penetrate further. Here, forging process has to be completed under more compressive forces for full penetration.
- Sometimes, due to excessive work pressure over surface, it breaks down even at low temperature. You should work at high temperature and check the surface tolerances from time to time.
- When flash passes through metal then crack penetrates deep into metal surface due to thin flash. Here, you should increase flash thickness, don’t pass the flash through most critical surface of metal and apply forces under less stress.
- When process is not completed with accuracy then two surfaces fold against each other without proper welding. The biggest reason behind this defect is excessive friction or chilling. The only solution is to increase fillet radius on the open die forgings India.
- At some places, dies are not completely filled by flowing metal due to improper quantity usage of raw materials or poor heating. The only solution is to opt for proper heating and right amount of raw materials.
- Have you ever noticed about poor alignment of flash lines? If yes, you should align flash lines properly first then proof read for proper alignment before any final execution.
- In some cases, Scales get embedded on metal surface due to oxidation. Here, you need proper cleaning prior to forging.
- Forging is popular all around due to its best grain structure. So, you have to extra cautious when designing or manufacturing dies otherwise grain structure will get disturbed.
