Rubber injection molding: The inherent complexity of various rubber compounds and their peculiar flow behaviour during molding reqires speacial attention.An integral approach to injection molding of rubber is needed which will take into account allmajor aspects of rubber behaviour, including modeling of flow into extruder, nozzle, sprue, runner system,and cavity, curing behaviour, packing, mold design, rheology and effect of processing upon structure and properties of molded products. A description of this integrated concept is the major trust of rubber injection molding.The process of rapidly forcing an exact amount of rubber from a tube/cylinder into a closed, heated mold. This process provides economical advantages including short molding cycle ,lower unit cost, high dimensional tolerances, absence of flash and little scrap/waste.
