Aluminum Alloy Die Casting Shifting Fork

This is a kind of Transmission Parts using in Auto area,the raw material is A380,a kind of material, having good fluidity, which is good for filling while die casting. This material is a good material to produce end cover, housing, gearbox, bracket etc.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.
To improve product quality, refining is carried out when the semi-finished alloy is completed. At the same time, install a fibre filter at the riser nozzle and a ceramic filter at the level gate of the gold tail liquid. 
It is also necessary to add a filter screen made of double-layer fibres to the residue of the horizontal gate and the slit to achieve three-time fine filtration.The technique difficulty of this Transmission Parts is the processing of holes, which requires very high precision and good process control.
