Requirements for Dies and Die Casting Process Settings for Aluminum Castings

During the production process of aluminum castings, the surface quality should be effectively controlled, and the roughness of the casting mold surface should comply with its relevant regulations. Aluminum castings are not allowed to have cracks, under casting, porosity, bubbles, and any penetrating defects.

Aluminum casting molds allow for defects such as scratches, dents, missing flesh, and network burrs. But the degree and quantity of its defects should be consistent with the standards agreed upon by both the supply and demand parties. The gate, flash, overflow port, separator, and ejector pin marks of the casting mold should be cleaned. But leaving traces is allowed.

Aluminum castings usually use their sand molds effectively, and the raw materials for the sand molds are mainly sand, which is mixed with binders, water, etc. to a certain extent. The sand mold material must have a certain adhesive strength in order to be molded into the desired shape and be able to resist the erosion of high-temperature molten iron without collapse.
