Temperature Cooling Control and Experimental Analysis of Automobile Wheel Hub Dies

Aimed at the problem of easy forming shrinkage in Al-alloy spoke wheel hub when using low pressure casting process to manufacture, a point-cooling temperature control technology was developed, the order solidification of alloy liquid was established by monitoring and controlling the spoke local temperature. The test result proves that this method is effective to solve the shrinkage problem at the root of spokes, it can be used for actual production.
