The heater and feeling the warm wax injection machine can make the wax liquid achieve and maintain a certain temperature.Generally wax wax injection machine temperature should be kept between 70 ~ 75 ℃, the temperature can ensure the liquidity of wax liquid.If the temperature is too low, wax liquid filled with wax models not easily, cause wax models of disability;Instead of wax liquid temperature is too high, and can lead to overflow or wax liquid from the film aperture place from wax injection overflow mouth, easy to form a flash or burn your fingers.Wax injection machine within the cylinder pressure is provided by the external air pump, the general should be kept in 0.5 ~ 0.7 at (or KGF/cm2) is between 0.051 ~ 0.071 Bar, can also according to the volume and complexity of wax models for appropriate adjustments.
