Mold opening can be wax injection after the operation.Wax wax injection operation should pay attention to the temperature, stress and plastic modulus of compression and other factors.Making wax models using paraffin wax is usually blue model, its melting temperature at around 60 ℃, wax injection temperature at about 65 ℃.There are some other colors of paraffin wax, nature is slightly different.Wax temperature and injection pressure is determined by the wax injection machine.The category of the wax injection machine usually has two kinds of wind pressure and vacuum.The two basic similar note wax principle of wax machine, is to use pneumatic the wax injection plastic mould molten state.The difference between the two lies in the vacuum type wax injection machine to plastic mold vacuum first, in the plastic mold injection wax;And wind pressure type wax injection machine can directly to the plastic mold injection wax.So usually operate in a vacuum type wax injection machine is relatively easy to grasp, and wind pressure type wax injection machine you may need to have certain experience.
