Physical Product Designer Question:

Producing good and constant quality at reasonable cost is what injection moulding is all about. Plastic components must be designed with the process in mind. It is therefore important for the designer to understand what happens in the mould during the production cycle. A few basic principles and some imagination are all that is needed for elementary flow and cooling analyses. How does the melted plastic flow, where does it (prefer to) go first? What happens when the material cools? How do the effects manifest themselves in the product and how should they be considered in the design? There is always some deviation in the process.
