In the process of production of aluminum alloy castings, because of various reasons such as technology, there may be flying edge.  But you do not need to worry, aluminum alloy die casting manufacturers to help you solve the problem of flying edge.

  
The so-called die casting flash refers to the appearance of a continuous sheet of metal on the edge of the casting, which can be identified by visual inspection.  Aluminum alloy die casting manufacturers summarized the reasons for the occurrence of flash: before injection, workers adjusted the clamping force of the machine is not accurate;  Die, die and slide block damage, locking element failure, or die insert and slide wear, or die strength is not enough to lead to deformation;  Parting surface has not cleaned up the debris;  The projection area was miscalculated and exceeded the clamping force;  The injection speed is too fast and the pressure impact peak is too high. 

Aluminum alloy die casting manufacturers have found out the causes of die casting flash, in order to avoid the casting flash, we should do these in production: before production, check the machine's die closing force and pressure, appropriate adjustment of injection increase mechanism, to ensure that the peak of injection boost is reduced;  Check molds and sliders, timely repair damaged sliders, to ensure that the locking elements play a role, repair worn sliders;  Calculate mould strength and clamping force correctly;  Clean up the debris on the parting surface;  Adjust the injection speed appropriately.
