Design and Analysis of Cap Forward Armrest Component

The aim of this paper is to design a mould cavity for a plastic component known as cap forward armrest component. Analysis was carried out in Moldex3D in which flow, pack, cooling and warp simulation are done for given component material and design parameters of process. Feed system designed is a submarine gate with geometrically balanced runners having diameter 6 mm to fill total injected plastic weight of 13.2 g. Fill time from fill and pack analysis is 0.473 s with no short shot (incomplete filling) and no weld lines created during moulding. With gate freezing completely, packing time calculated for the process is 5.5 s. Fill time in transient analysis is increased to 0.496 s. Form analysis injection pressure determined was 33 MPa, and the filling sprue pressure was found to be 27.71 MPa. The results obtained were satisfactory in producing good quality product within less time and with low cost.
