Application of Investment Casting in New Energy Vehicles

Investment casting is a process that uses a disposable wax pattern to create a permanent ceramic mold for shaping an object. After the ceramic mold hardens, it is heated to melt the wax and drain away. The molten metal is then poured into the ceramic mold to form the desired object. The process is used in a variety of industries, including the automotive industry. In fact, investment casting is widely used to manufacture parts for new energy vehicles.

Investment Casting and New Energy Vehicles

Investment casting offers many benefits and is often used for complex and intricate shapes. Parts made using this process have smooth surfaces, are lightweight, are very heat-resistant, require less lead time and labor than parts made using most other processes, and have tighter tolerances. In addition, investment casting can be used with a variety of materials to create objects of various sizes. These advantages make the process well suited for new energy vehicles, which include plug-in electric vehicles, battery electric vehicles, fuel cell vehicles, and hybrid vehicles.

Sample parts of these vehicles manufactured using investment casting include:

Motor housing

Battery box

Onboard charger

DC-AC converter housing

HV/EV ECU housing
