Die casting causes flash with:
1) problem: die casting machine clamping force adjustment.
2) process problems: injection speed is too high, the formation of high pressure shock peak.
3) mold problems: deformation, sundry on parting surface, insert, slider wear not flush, template strength is not enough.
To solve the sequence casting measures flash: clean the parting surface, improve the clamping force, adjusting process parameters and mold repair wear parts, improve the mold stiffness. From easy to difficult, do each stepimprovement, first to test its effect, then the second step. [knowledge] Qingdao die casting |
