The method of duplicating internal cavity is copying the internal shape with silicon rubber and other elastic material characterized low melting and rapidly solidified, which be injected in the valve body and taken out Fig. 1 The valve body with internal cavity after solidification easily, the external surface of the entity is regarded as the internal cavity so that it can be measured expediently and easily.
A technical trick can be used in this process because of the softer silicon rubber, a clava is inserted in internal cavity filled with liquid silicon rubber, it can not only reduce the material consumption, but also decrease deformation of silicon rubber entity.
The next step is cutting out the material entity of the internal cavity based on the solid model created above according to the curves of the internal surface, which is also imported in the CAD software.

Layout optimization which includes size, shape and topology optimization is to find the optimal distribution of materials and minimum weight or cost structure with a given external load so it can avoid the lack of current design[1].
Solid Isotropic Material with Penalization (SIMP)[4] model expresses the stiffness and density for each element using the following well-known power-law relationship (2) Where Ei0 denotes the initial Young’s modulus of the ith element; Ei denotes the pseudo-modulus of the ith element, p is a penalization parameter; ρi0 denotes the initial density of the ith element; ρi denotes the pseudo-density of the ith element.
