Injection moulds are divided into two types based on runner design (i.e.) Cold runner moulds and Runner less moulds (i.e.) hot runner moulds. In cold runner moulds, for multi-cavity and multi-point injection moulds, there is wreckage of material in runner area. Sometimes wreckage of material is more than component weight. For avoiding the above problem, the technique used is hot Runner moulds. Hot runner mould is the advanced manufacturing methods for multi-cavity type moulds. These types of moulds are widely used for large production rate. While producing plastic components using normal/standard multi-cavity mould, we are facing the problems like partial filling, cavities in components, less product quality, injection pressure and temperature drop age and warpage etc. Thus we are redesigning the Ceiling Fan Regulator Knob by doing some modification in and this will be beneficial for our using purpose. We are making design of the component, mould flow analysis using software Solidworks.
