Injection Moulding Process, MoldFlow Analysis for plastics parts using Autodesk MoldFlow insight

Flow analysis

Flow analysis simulates the filling and packing phases of the molding cycle. Different process conditions can be evaluated and most appropriate process parameters can be chosen to produce the part.

For a set of process inputs (injection time, melt and mold temperature, pack profile etc) the following results can be seen:

  • Injection pressure
  • Clamp force
  • Temperature reduction at flow front
  • Weld line locations
  • Air trap locations
  • Volumetric shrinkage, etc.

Based on these results the most optimum process condition can be chosen.

MoldFlow Analysis Service using Autodesk MoldFlow insight

Cool analysis

Cool analysis helps to optimize the cooling circuit design of the mold to achieve uniform mold cooling and achieve minimum cycle time.
Non-uniform temperature distribution can lead to warpage and related part quality problems.

Cooling analysis determines the temperature distribution on the cavity and core for the given process condition. Based on this suitable modifications to the mold design can be derived.

Choices of providing inserts made of materials with higher heat extraction capability in areas of hot spots in the mold can be evaluated using the
cooling analysis

Ultimately the optimization of mold design using cooling analysis to minimize the cycle time has the benefit of yielding greater productivity.

Cool analysis facilitates:

  • Optimum Cooling circuit design.
  • Location of hot spots.
  • Better core/cavity temperature setup.
  • Evaluation of Cooling efficiency in core and cavity side.
  • Optimization of cooling time required.

Warp analysis

Warp analysis determines the causes of warpage in molded parts and predicts where the warpage will occur in the part.
Based on the causes of warpage as seen from the analysis, part warpage can be controlled by optimizing design, material and processing
Overcoming of warpage problems in the design stage itself helps to avoid costly reworks on mold and time delays.

Warp analysis facilitates understanding of:

  • Deflection in X, Y and Z direction.
  • Effect of corrective actions to minimize warpage.
  • Final shape of the product.
