Casting is a metal smelting process, usually by using the gravity of the metal in the mold for casting. But “aluminum die-casting” is not done by gravity, it’s done by pressure. It’s kind of like injection molding. But it has a higher technical content of the core, cooling and other systems. In general, materials are delivered through a centralized inlet into the cavity to be cast and “molded” to form the part. Aluminum has a history of more than 100 years since it was discovered by the Danish scientist H.C.Orsted in 1825. It has been more than 100 years since…

Which method is more cost-effective, such as prototype 3D printing or CNC processing?
During prototype proofing, some products can be made either by CNC processing or by 3D printing. Because CNC processing is relatively complicated and the workload is larger than 3D printing in theory, most customers take it for granted that CNC processing is more expensive than 3D printing. Is this the case? Li Gong, the professional master of precision models, introduced the differences between the two processing methods in detail According to Li, CNC processes need to be programmed and disassembled. Generally, a CNC machine needs 3-4 people, which means a large labor cost. Therefore, the cost of CNC mainly depends…

The traditional die casting process is mainly composed of four steps, or called high pressure die casting. These four steps, which include mold preparation, filling, injection, and sanding, are the basis of various modified die casting processes. During the preparation process, a lubricant is sprayed into the mold cavity. In addition to helping to control the temperature of the mold, the lubricant can also help to release the casting. The mold can then be closed and the molten metal is injected into the mold at a high pressure ranging from 10 to 175 mpa. When the molten metal is filled,…
