During the product design, many decisions are made that affect cost and quality, and unfortunately many decisions are made in a knowledge vacuum by a product designer. Once he\/she is done many of the costs are locked in. <a href=\"https:\/\/www.acomold.com\/benchmark-simulation-software-moldflow-moldex-cadmould.html\">Moldflow<\/a> introduced Autodesk Simulation DFM, to help a designer develop a viable plastic part (this is as much as you can expect from a designer). Feedback on manufacturability is provided in real time. It uses minimal input from the designer, and can help avoid basic and obvious mistakes before they become expensive.<\/p>\n<p>After the designer is done, someone has to figure out how to make the plastic part. This requires expertise and a different set of tools like Moldflow Adviser or Insight. This requires a different user, more precise input and results accuracy. These tools should ideally be used throughout the product development, rather than at one single stage in the process. A designer does not have the background of plastics expert, and analyst should not have to chase down basic design errors.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A good mold flow analysis has lots of benefits, although it is time consuming, the cost is much lower than the cost of trials during nights and days on a production injection molding machine.
