molding surface
3.In this preparation nanocomposites technology is adopted, compositive refractory material is used as the main raw material and nanometer materials are used as betterment additives. By adopting plastic admixture, homogenization of the body batch,extrusion molding, micro-wave drying,sintering to net size and so on,the products attain good using effects. Its surface porosity is 60～80%,compression strength>25MPa, thermal expansion coefficient<6×10-6/℃,using temperature 1400～1850℃.
5.Abstract: In this paper,a trimming method for subdivision surface is presented.It is applied well in the CAD/CAE system of plastic injection molding,and also useful for other designing of products and field of FEM analysis.Experimental results show that the method is highly automatic,quick and stable.
6.Based on Hele-Shaw flow model, methods of model integrated analysis were studied for injection molding parts with complex surfaces. The technological frame and executable steps were put forward,which estimate injection moulding in product structure in advance and add thickness attributes on CAE mesh model according to the CAD geometry surface when solid models of the parts with complicated surfaces were constructed.
7.Uses the high quality special molding manufacture, but becomes by the kneading board and the leg combination; Has the contour artisticly, firm is durable, does not need to maintain and so on the merit; The kneading board and the inside lining stiffener spreads across, the bearing power optimizes, Leg each strengthens processing, the average distributed load; The surface uses galvanizes or the static electricity spurts models processing, is advantageous for cleanly, is not easy to pollute; Is suitable in various professions, the many kinds of situations, the use scope is extremely broad.
