tion of injection moulded components. The company provides CAE solutions in areas including plastic part design optimisation, material selection, mould cooling design optimisation, moulding and process validation, design of experiment (DOE) and injection moulding troubleshooting using a range of software systems, including the Moldex3D simulation software. Jasmin Wong, Project Engineer at Plazology, describes how the cycle progresses and emphasises how the design process with simulation can provide signifi cant advantages. “A normal design cycle starts with the concept, through design into validation and then fi nally production,” she says. “However, although simulating the injection moulding process via fi nite element method increases the design time, the validation stage is signifi cantly reduced because fewer physical prototypes are required. This gives substantial savings in terms of time and cost. It is critical to simulate early because this allows the time to achieve the greatest infl uence on the part design.” CAE can assist at virtually all stages of the work fl ow


cycle. “The initial product design should take design for manufacture (DFM) into consideration. By carrying out

injection moulding simulation at the design stage, typical potential defects such as short shot, air trap, weld lines and sink marks can be identifi ed and eliminated prior to building of the mould tool. Only after part design is predicted to be well within specifi cations can we progress to the mould design evaluation. This is to allow a wider processing window. Typical problems that can be solved at this point include runner imbal- ance and poor cooling layout, which can result in high warpage. Once the mould design is optimised, then it is possible to progress to mould manufacture,” she says.
