Aluminum die-casting products are primarily used in the electronics, automotive, motor, home appliance, and some communication industries. Some high-performance, high-precision, and high-tensile aluminum alloys are also utilized in industries with stringent requirements, such as large aircraft and ships.

With the rapid development of die casting technology, the die casting industry has gained significant attention, particularly with the diversified development of materials such as aluminum alloy die casting and zinc alloy die casting, which has further accelerated the widespread application of die casting, especially in the use of aluminum alloy die casting molds.

However, in the actual application of aluminum alloy die casting molds, people often fail to understand how the surface quality of aluminum alloy die casting molds is?

If not specified in the design, the settings for the die casting process, such as the position of the ejector rod, the location of the parting line, and the positions of the sprue and runner, shall be determined by the manufacturer. Otherwise, such details should be noted in the design or agreed upon by both parties.

2. Aluminum alloy die-casting molds require special surface processing, such as polishing, shot peening, chrome plating, coating, anodizing, chemical oxidation, etc., which must be noted on the drawings or agreed upon by both parties.

3. Aluminum alloy die-casting molds may have scratches, dents, lack of material, and network-like burrs, but the degree and quantity of these defects should be consistent with the standards agreed upon by both parties.

4. Aluminum alloy die casting molds should be cleaned thoroughly of gates, flash, overflow gates, skin, and pin marks, but traces are permissible.

5. Cast molds must not have cracks, under-cast, porosity, bubbles, or any penetrating defects.
