Process Architecture, a story


On the way to create, part designers tend to look at the geometry of their part in idealized characteristics such as isotropic material properties. These perfect properties are like a fairytale weaving a merry tune but often end with being eaten by the wicked (polymer) witch.  

Not to be cruel but part designers tend to feel that they have "years" of designing with polymers and with the process, however, I find that this is not the case, the required depth of knowledge is lacking in very many cases.


Working with plastics requires depth in all aspects of the triad, Design-Tool-Process. Whether this is accomplished with the designer or by augmenting the knowledge base with additional resources the triad needs to be fulfilled. The tool design cannot be isolated from Design nor Process. These are interwoven, connected to drive for a successful part result. The principle characteristics needed for successful plastic parts is control flow and thermal behavior


Plastic part design starts with a detailed review of the goals for the part, what does it want to be when it grows up. A method to accomplish this is through the DfM process. This process applies a disciplined approach and system to detail, discover and record the requirements. The DfM process will stay with the part throughout its life.
