Aluminum alloy die-casting products are mainly used in electronics, automobiles, motors, home appliances and some communication industries, etc. Some high-quality aluminum alloy products with high performance, high precision and high toughness are also used in large aircraft, ships and other industries with high requirements.

With the rapid development of die casting technology, the die casting industry has been paid attention to, especially the diversified development of aluminum alloy die casting and zinc alloy die casting materials has promoted the rapid application of the die casting industry, especially the application of aluminum alloy die casting molds.

However, in the practical application of aluminum alloy die casting mold, people often do not understand what the surface quality of aluminum alloy die casting mold is.

1. If there is no special provision in the drawing, the setting of the die-casting process part, such as the position of the ejector rod, the position of the parting line, the position of the gate and the overflow port, shall be specified by the manufacturer itself, otherwise it shall be indicated on the drawing or agreed by the supply and demand parties.

2, aluminum alloy die casting mold requires special processing of the surface, such as polishing, shot peening, chrome plating, coating, anodizing, chemical oxidation, etc., must be indicated on the drawing or agreed by the supply and demand parties.

3, aluminum alloy die casting mold is allowed to have scratches, dents, lack of meat and mesh burrs and other defects, but the degree and number of defects should be consistent with the standards agreed by the supply and demand parties.

4, aluminum alloy die casting mold gate, flash, overflow, partition, top bar traces should be cleaned, but allowed to leave traces.

5, the casting mold is not allowed to have cracks, under-casting, porosity, bubbles and any penetration defects.
