Aluminum 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. Discover additional details 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.
During casting, some of the components of the sand mixture are lost in the thermal casting process. Green sand can be reused after adjusting its composition to replenish the lost moisture and additives. The pattern itself can be reused indefinitely to produce new sand molds. The sand molding process has been used for many centuries to produce castings manually. Since 1950, partially-automated casting processes have been developed for production lines.
The aluminum die casting process typically has five steps, the two halves of the die mold are first cleaned to remove any residue from the last injection. Then, each half is lubricated to facilitate ejection from the mold later on in the process. After lubrication, the two halves of the die are properly clamped together. Sufficient force is needed to keep the two dies securely clamped together. The time needed to close and the clamp will increase with the size of the machine.
