DFM & Simulation for Injection Mould of Knob

This work deals with injection moulding simulation of Knob, in which the gate location, diameter and the possible defects during the filling& packing phase is determined and warpage effects under variable shrinkage with process parameters. In this simulation process is carried out by using Hyper mesh and Mould Flow Software. In the Hyper mesh phase, meshing works are carried along with thickness assignment. In the Mould Flow phase, material flow, positioning of gate location, gate size and analysis of defects are determined here. The component tested virtually is Knob that used to set/tune the time for a wash in Washing machine
