The main parameters of inhibition can be changed randomly in the whole process of inhibition.

When using new abrasives, try to make clear the order of assembly disassembly of abrasives, the removal method of wax mold.

When storing wax mould, pay attention to the idle position to avoid deformation. If necessary, the pipe buckle other measures can be adopted to prevent the wax mold deformation.
