Aluminium die casting supplier by aludiecasting.com

Aluminium die casting provider in China? Gc Precision Mold Co.ltd is an experienced vacuum zinc die casting manufacturer. Zinc Die casting is characterized by forcing molten zinc under high pressure into a mold cavity, which is machined into two hardened tool steel dies. zinc is the easiest alloy to cast, has a low melting point and is economical and easily palatable. Zinc also has high impact strength, offers high durability and promotes long die life. OUR Metals is very beneficial for polished die castings, particularly those which are gold plated, or coated with zirconium nitride (ZrN), titanium nitride (TiN) or chromium nitride (CrN), by physical vapour phase deposition (PVD) processes. Aluminum die casting is efficient and economical and offers a wide range of durable shapes and components. Little or no machining is required after a part is die-casted, because the process provides very close tolerances for even complex shapes. See extra info at China die casting.

Aluminum die casting benefits : Strong, Lightweight and Resilient Die Cast Aluminum: this die casting process creates an aluminum alloy that is lightweight yet extremely strong and capable of withstanding higher operating temperatures than any other die cast alloy. Additional benefits of die casting aluminum are that it is extremely resistant to corrosion, has excellent electrical and thermal conductivity and is fully recyclable and reusable in production. It also has outstanding EMI and RFI shielding properties.

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.

The accuracy of the casting is limited by the type of sand and the molding process. Sand castings made from coarse green sand impart a rough texture on the surface of the casting, and this makes them easy to identify. Air-set molds can produce castings with much smoother surfaces. Surfaces can also be ground and polished, for example when making a large bell. After molding, the casting is covered in a residue of oxides, silicates and other compounds. This residue can be removed by various means, such as grinding, or shot blasting.

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.
