piston produced through the use of additive manufacturing techniques

摘要

1/1 summary “Piston produced using additive manufacturing techniques” is a one-piece piston body for an internal combustion engine. the piston body includes a first part including a pair of flange portions and a pair of pin shoulders and a second part including a crown portion with an upper combustion surface and an at least partially confined oil gallery. The first and second parts are joined in a joint that is located on one side of the oil gallery opposite the upper combustion surface. The first part is produced by casting or forging, and a second part is produced by an additive manufacturing process, such as direct laser metal sintering.
