Injection Molding Simulation

Injection-Molding is a complex operation involving non-linear non-isothermal dynamic flow of a visco-elastic material which undergoes a melt to solid transition. The flow behavior is complicated by the fact that the material is shear thinning and experiences extensional effects as it flows through contractions and around corners, features that are typical in an injection-molded product. Finally, as the product solidifies, the plastic shrinks in a non-uniform manner that depends on a number of factors that include flow induced stresses, thermal effects and for semi-crystalline materials, the degree of crystallization and the crystalline morphology. An understanding of that effects are accounted for in the simulation aids in the proper interpretation and use of the CAE results.
