Exploration of Investment Cast ZL114A Aluminum Alloy Casting by Preset Gypsum Cores
The soluble core is often used for aluminum alloy precision casting with tubular circuit for the difficulty in core pulling during the wax pattern making.However,the precision casting is prone to defects such as scabs and runner blockage.Therefore,this paper improves the method by using a preset gypsum core and compares the casting effects of the two methods.The results show that the preset plaster core is indeed feasible.
