Applications of Investment Castings in New Energy Cars

Investment casting is a process that uses a disposable wax mold to create a permanent ceramic mold which is used to shape an object. After the ceramic mold has hardened, it is heated, causing the wax to melt and drain away. Molten metal is then poured into the ceramic mold to form the desired object. This process is used in a variety of industries, including the automobile industry. In fact, investment casting is widely used to manufacture parts for new energy cars.

Investment casting and new energy cars

Investment casting offers a number of benefits and is commonly used for intricate and complex shapes. Parts made using this process have a smooth finish, are lightweight, are very heat tolerant, require less lead time and labor than those made using most other processes and have tighter tolerances. In addition, investment casting can be used with a wide variety of materials to create objects in a wide range of sizes. These benefits make the process very well-suited to new energy cars, a category that includes plug-in electric vehicles, battery electric vehicles, fuel cell vehicles and hybrid vehicles. Just a sampling of the parts for these vehicles made using investment casting include…
