Description

Four MIM parts—blank discharge check, stop discharge check valve, valve discharge check, and CRV spring seat—that go into a device that controls fuel flow in Gasoline Direct Injection (GDI) pumps.Three of the parts are made of 440C stainless steel, while the fourth is made of 17-4 PH. The extremely complex geometry of the blank discharge check, with the intercrossing of holes, required tooling with six side cores, three of which move at different timings. The annual volumes are close to 1.2 million pcs a year each. The parts are designed for MIM. All the 4 parts go into a device which controls the fuel flow in Gasoline Direct Injection (GDI) Pumps of passenger cars.
