Auto Transimission die casting Mounting

This is a kind of Transmission Parts using in Auto area,the raw material is ADC12.The main processes are die casting,CNC Milling,CNC Turning. In the die casting process,higher specific pressure is required, so that higher filling speed can be obtained, which is beneficial for alloy to overcome mold filling resistance and effectively fill each part of the cavity. The Casting General Tolerance is Grade GB-CT4. If product structure is unreasonable, will cause uneven contraction, if mold is opened too fast, the product does not have complete solidification cooling, it is necessary to change the product structure, adjust the mold opening time. otherwise, will cause shape deformation. There are many methods used for centuries for casting metals.Some of these methods date back over 5000 years.One of the most modern and effective methods is die casting. For the four BOSS column screw holes of this Transmission Parts,we choose to form the bottom hole through the die casting process, and then…
