Top rated aluminum die casting provider
Best aluminium die casting producer? Fine blanking machinery used for Automotive components, power tool components and textile machinery components. The process of fine blanking holds very tight tolerances and sometimes can eliminate secondary operations. Materials that can be fine blanked include aluminum, brass, copper and carbon, alloy and stainless steels. The vacuum aluminum die casting process was originated and developed China, GC Precision Mold is the die casting manufacturer who has reached experience in this die casting process. Aluminum die castings can also be easily plated or finished. Aluminum die castings are dimensionally stable and heat resistant. Find even more details on Die casting China.
Once the cooling time has passed, the die cavity can be opened and the ejection mechanism can be employed to push the casting out. The ejection mechanism will need to employ some force in pushing the casting out as the part usually shrinks while cooling and adheres to the die. Once the casting is ejected, the die cavity is closed and ready for the next injection. During the cooling process, some aluminum will have solidified and attached itself to the walls of the channels of the die. These redundant elements will need to be removed. This removal is called trimming. This can be done manually in which case sawing or cutting will be the method employed, or it can be done using a trimming press. The trimmed aluminum can be disposed of or recycled.
Aluminum gravity casting can be operated both by handwork or by gravity casting machines. Because of the low cost of labor force, mostly china gravity casting foundries handle such casting process by handwork without any assistant machines. Though compared that assisted by machines it has a low production capacity, yet for a small quantity of some gravity casting part, such handwork can have a much lower unit price. Our mission is to provide the aluminium gravity die castings with the highest quality, at a competitive price and with value-added service to our customers. Our aluminum gravity casting products maintain great flexibility in the production and shipping schedule, which enables us to better meet customer demands.
There are two main types of sand used for molding. “Green sand” is a mixture of silica sand, clay, moisture and other additives. The “air set” method uses dry sand bonded to materials other than clay, using a fast curing adhesive. When these are used, they are collectively called “air set” sand castings to distinguish these from “green sand” castings. Two types of molding sand are natural bonded (bank sand) and synthetic (lake sand), which is generally preferred due to its more consistent composition.
Aluminum die casting process: requires the cold chamber process, the method of transfer to the chamber is manually ladling the molten metal into the shot chamber from where a hydraulic powered plunger will push the molten aluminum into the die. The injection time is the time required for the molten metal to fill all parts of the cavity. This is usually a very short time to prevent the molten aluminum from solidifying too early, before having filled the mold. For the cold chamber process machine, the injection time also includes the time it takes to manually ladle the molten aluminum into the chamber.
