The recent rapid growth of the Vietnamese automobile market is convincing proof that the Government has been giving the industry a close interest in formulating policies to build and develop the industry. In particular, the automobile production and assembly industry are increasingly focused on developing, thereby confirming the competitiveness of domestic cars with imported cars. However, up to now, supporting industries for the automobile manufacturing industry in Vietnam are still very rudimentary. To help the automobile industry, increase the localization rate for cars manufactured in Vietnam, this article focuses on the assessment of manufacturing technologies and materials used in the manufacturing process for pistons of automobile engines, from which to find the most suitable technological solution and material for the manufacture of this part in Vietnam. Many casting technologies can be used to produce pistons for automotive engines such as die-casting and centrifugal casting. The choice of the appropriate casting method depends on the manufacturer’s decision. The trend of choosing aluminum alloy materials for piston production still dominates although steel and new materials have confirmed their role.
