Solution of Surface Bubbles in Die Casting Aluminum Alloy
The surface of the casting has a cavity formed under the raised skin of rice grain size.
Solution to surface strain of aluminum alloy die casting
① The surface of the mold cavity is damaged; ② The direction of the mold is not inclined or the inclination is too small; ③ The ejection is unbalanced;
Solution of Surface Crack of Die Casting Aluminum Alloy
The surface of the casting is linear or wavy lines, narrow and long, under the action of external force has a development trend; cold crack cracking metal is not oxidized; ③ hot crack a crack metal has been oxidized.
Solution of flow mark and pattern of die casting aluminum alloy
There are stripes on the surface of the casting in the same direction as the flow direction of the metal, and there are obviously visible non-directional lines with different colors from the metal matrix, and there is no development trend.
Solution to discoloration and spots of die-casting aluminum alloy
Different colors and spots appear on the surface of the casting.
Solution to IEI Trapping of Die Casting Aluminum Alloy
Dents appear on the smooth surface of the casting.
Solution of burr and flash of die-casting aluminum alloy
Die castings have a sheet of metal on the edge of the parting surface.
Solution of shrinkage cavity and shrinkage porosity of die-casting aluminum alloy
① Anatomy or flaw detection inspection, the hole shape is irregular, not smooth, the surface is dark; ② large and concentrated for small shrinkage and scattered for shrinkage.
Deformation Solution of Die Casting Aluminum Alloy
① Overall deformation or local deformation; ② Die casting geometry drawings do not match.
Die-casting aluminum alloy cold isolation solution
The surface of the die casting has obvious, irregular, sunken linear lines (penetrating and non-penetrating). The shape is small and narrow, and some of the transition edges are smooth, which may develop under the action of external force.
Die-casting aluminum alloy mesh wool wing solution
There are traces of protrusions or depressions like reticular hairs on the surface of die castings, which are continuously expanded and extended with the increase of die casting times.
Solution to Undercasting of Die Casting Aluminum Alloy
The casting surface has underpoured parts; the contour is not clear.
Solution to Porosity of Die Casting Aluminum Alloy
