1) kind of wax tree waterway and wax models generally have a 45 ° Angle between rods, that is, the direction of the wax models is tilted upward.Only in this way can facilitate the goldwater smoothly into the plaster mould.This Angle can be according to the size of the wax models and complexity appropriate adjustments, small and complex wax models can decrease the Angle;On the other hand, the bigger of the wax models can increase the Angle.2) before a wax tree, should first to weighing the rubber chassis.A wax tree, again weighing.The results of the two weighing subtraction, can obtain the weight of the wax tree.According to the weight of the paraffin wax tree with the weight of the casting metal density in the conversion ratio of metal, can estimate how much about metal casting.3) kind of wax tree, must check whether the wax models have been welded.If there is no weld, when pouring gypsum is likely to cause falls off wax models, affect the proceeding of the casting.Finally, should check whether there is enough space between the wax models, wax models if the stick together, should be separated;If you have any drip drip wax, wax tree to should use the blade.
