If simulation is used in parallel to part and mold design, an efficient production is ensured.
Therefore, part costs will be minimal due to low cycle time and lowest need of precious resources.
As Part Designer, you bear the main load of the responsibility for part costs.
The later an error is found, the more money is needed to solve it (factor 10 for each step further away from part design).
A simple filling analysis will provide all answers needed to ensure the best part design.
As Project Manager, you need to tighten the work flow within the whole development and production process. One critical thing is to minimize time loss due to modifications on a finished mold. The consequent use of simulation is your chance to create a hassle free process for each of your projects. Simulation ensures that you will get a mold, which can be used without or with only minimal further changes. Possible threats are known upfront and can be taken care of early in the process.
An efficient production and a stable quality of produced parts are the responsibilities of the Quality Manager. Foregoing simulation will point out realistic cycle time and the required process window for manufacturing. Evaluated data will be compared with information from production to ensure a profitable process. Good plans to check part quality are done taking simulation results into account.
