Abstract

Aluminum cover of engine for Honda car was manufactured by die casting.The predominant factors influencing the cover quality include advanced mould design

proper injection parameters

special moldfication for aluminum melt

rational improvement of ingate and exhaust pipe and proper control of die temperature.Some predominant parameters were determined including slow-injection velocity of 0.2～0.3 m/s

fast-injection velocity of 6.0～6.3 m/s

fast-injection distance of 460 mm and applying-pressure specific pressure of 33.6 MPa

applying-pressure distance of 510 mm

holding pressure of 8 s

pouring temperature of 680 ℃ as well as die temperature of 140～260 ℃.
