Since the force may also be affected by the fragment with different sizes and shapes, extrusion between the ore, humidity, density and other uncertain factors, even shoveling the same kind of material, the load data may be not regular at all [10].

The empirical formula provided by Tait is usually used to express the relationship among P-V-T during pressure maintain process: ; ;; Where Tg is the glass transition temperature ( for nonlinear materials ) or the crystallization temperature (for crystalline materials).
In the above equations, b1,1~b9 are material constants.
When establishing the mathematical model of temperature field in the process of cooling, simplifying should be done as follows: Ignores the gap thermal resistance between cavity with plastic melt, and takes heat-conducting properties of the mould materials as isotropic.
