METHOD FOR THE PRODUCTION OF A THROTTLE VALVE PORT

摘要

Disclosed is a method for producing a throttle valve port, according to which a first half (1) and a second half (2) of a housing are produced with corresponding cavities for internal parts (4) in a casting process in a first step. The internal parts (4) are then placed within the first half (1) or the second half (2) of the housing in a second step, whereupon the first half (1) and the second half (2) of the housing are connected to each other in a third step.
