CAE Injection molding analyses

Analysis of an injection molding cycle
Simulation of processes

We analyse potential risks and propose a way of treatment for most technologies of injection molding of thermoplastics and thermosets.

Analysis of an injection molding cycle

We use pre- and post-procesor Moldflow Synergy for analysis. Synergy contains a very efficient generator of a Midplane mesh, DualDomain and volumetric tetrahedral mesh and a sofisticated editor final element mesh.

CAD data can be imported from all common CAD systems, parts as well as assemblies. Unique database of 10 000+ polymers and grades.

Simulations are done in Autodesk Moldflow Insight Ultimate.

Simulation analysis of the cycle shows:

  • Locations of melt flow slow down in the cavity
  • Weld lines and their effect on quality
  • Shear stress of the melt and risk of degradation
  • Air traps and trapped air back pressure, air hooks
  • Potential void locations
  • Pressure at the cavity entrance, pressure field during the cycle
  • Clamping force of the injection machine
  • Melt flow front temperature, temperature field of the part during the cycle, temperature field of the mold during the cycle
  • Weight of the part
  • Orientation and anisotropy of strength of the part made of fiber-filled plastics
  • Longitudinal and transverse shrinkage of plastics with CRIMS data measured
  • Warpage of the part after ejection from cavity and warpage causes

Simulation of processes

Besides standard injection molding of thermoplastics we simulate

  • Metal and plastic insert overmolding
  • In-mold labeling, in-mold lamination
  • 2K and 3K injection molding
  • Rapid mold heating and cooling using water, steam, heating cartridge, induction heating
  • Conformal cooling
  • Gas-assisted injection molding (GIT)
  • Microcellular injection molding with and without core back
  • Injection with a chemical blowing agent (CBA)
  • Injection-compression molding with packing by mold or core back
  • Co-injection molding
  • Bi-injection molding
  • Powder injection molding
  • Compression molding
  • Rubber, liquid silicone injection molding
  • Resin transfer (RTM) and structural reaction injection molding (SRIM)
  • Reaction injection molding
