Plastic Flow Simulation

In NX EasyFill Analysis, you can evaluate molding related issues that significantly influence the quality of plastic parts, such as cooling time or melt front temperature. It also enables you to make changes upfront to optimize part design, gate number/locations, material selection or process conditions. Ultimately, NX EasyFill Analysis helps designers efficiently achieve higher quality and lower costs.

Capabilities

  • Automatic meshing and injection knowledge: EasyFill uses proprietary automatic meshing technology that generates high-quality 3D analysis meshes from NX part models
  • Melt front time simulation: NX EasyFill helps designers explore the filling pattern of the mold by simulating melt front time.
  • Air trap simulation: Designers can use NX EasyFill Analysis to visualize the position of air traps in the molding process.
  • Weld line simulation: With NX EasyFill Analysis, you can observe the results and optimize gate locations.
  • Pressure drop analysis: NX EasyFill Analysis simulates the drop in pressure at the flow front of the plastic due to drag and frictional effects in the mold. The pressure drop simulation displays the pressure distribution of the part cavity at the end of filling (EOF) stage.
  • Melt front temperature prediction: The results help designers identify areas of excessive heating or cooling, and to determine the appropriate fill speed for uniform temperature distribution.
  • Maximum temperature: EasyFill calculates and displays the maximum temperature distribution during the filling process.
  • Average temperature: With NX EasyFill’s average temperature simulation, designers can check the combined effects of viscous heating of polymer melt and mold cooling across the part thickness at any instant.
  • Gate contribution simulation: EasyFill calculates each gate’s percentage of total plastic flow into the cavity.
  • Frozen layer ratio: EasyFill simulates solidification of frozen layers near the cavity surface caused by cooling.
  • Maximum cooling time analysis: The maximum cooling time calculated by EasyFill Analysis shows the estimated cooling time required under the given design and process conditions.
  • High performance parallel computing: NX EasyFill Analysis supports parallel computing and can be used to reach the maximum acceleration by fully using each core of modern CPU architectures (maximum 4 cores).
  • Packaging and availability: EasyFill Analysis is available as an add-on software application for NX Gateway and NX Mach Series solutions that run on Windows operating systems
