Material mechanics properties of sheet machine analysis ( On)

Sheet machine equipment is the production of plastic molding products, plastic molding plastic products is a necessary process. And before the production of plastic products, need to be material mechanics analysis, it is whether the material qualified, whether important detection composite production standard, here is to introduce a little material machine and mechanical properties of the materials needed to produce. Material by external force, its internal will produce an internal force to resist external force, also with the deformation of the material. Based on the characteristics of deformation, deformation can be divided into elastic deformation and plastic hand in two typical cases. The material deformation under the external force, when the external force to cancel, the nature of the deformation can disappear completely is called elastic deformation of completely disappear is called elastic deformation. The action of external force and material deformation, when the external force to cancel remained after the deformation state and size, and not the nature of the cracks is called plasticity. This can't restore deformation is called plastic deformation. Lunch box machine in the production of plastic box is a kind of elastic deformation of the material. In fact, there is no pure elastic or plastic material. Of various materials under different stress, will show the different deformation performance.
