With the rapid development of die casting technology, the corresponding application of die casting industry has been popularized, especially aluminum alloy die casting and zinc alloy die casting and other material diversification development has promoted the rapid application of die casting industry, especially the application of aluminum alloy die casting mold. However, in the actual application of aluminum alloy die-casting mold, people often do not understand the surface quality of aluminum alloy die-casting mold is what? The following is a brief introduction to the 6 requirements for surface quality of aluminum alloy die-casting die by Fu Rong die casting.

1. If there is no special stipulation in the drawing, the installation of the die casting process, such as the position of the ejector, the parting line, the gate and the overflow gate, etc., shall be determined by the manufacturer itself. Otherwise, the drawing shall be marked or agreed by the supplier and the demander.

2. Surfaces requiring special processing such as polishing, shot peening, chromium plating, coating, anodizing, chemical oxidation etc. should be marked on the drawings or agreed by both suppliers and consumers.

3, casting mold allows abrasions, dents, lack of meat and mesh burrs and other defects. However, the extent and quantity of its defects should be consistent with the standards agreed by the supplier and the buyer.

4, casting mold gate, flare, overflow mouth, skin separation, ejector trace and so on should be cleaned up. But allowed to leave traces.

5, casting mold does not allow cracks, lack of casting, loose, air bubbles and any penetrable defects.

6, the surface roughness of the casting mold should comply with the requirements of GB/T15114-1994.
