A, lost wax casting the effects of cold deformation:After annealing in products, mechanical processing of warping deformation of skew, etc.1, reason: because the casting residual stress, released in the process of bad.2, countermeasure: the optimization of product design, increasing reinforcement, in order to increase rigidity;Reduce the lost wax casting casting stress, reduce the pouring temperature, mold temperature reduction, to extend the time for mould;Optimization of annealing process, adjust the time, temperature, cooling way.
