Injection molding simulation for thermoplastic parts

Injection molding simulation software helps manufacturers verify and optimize polycarbonate part and mold designs by providing visual and numerical feedback on injection molding production. Using CAE simulation software helps reduce the need for costly physical prototypes, avoid manufacturing defects and reduce the product’s time to market.

As technologies advance, so do the capabilities of CAE for injection molding simulation. CAE software allows designers to see simulations in 3D for quality prediction of optical lenses. It’s also possible to detect and troubleshoot shrinkage and warpage, and provide detailed hot runner simulation.

Without injection molding simulation, its likely that many issues would not be discovered until molding has begun, translating into additional time and expense.

 

To support customer projects Covestro utilizes the following simulation methods:

„Conventional“

  • Filling and holding pressure
  • Optimization of filling (gate location, part geometry)
  • Runner balancing
  • Clamping force
  • Shrinkage / Warpage

Special technologies

  • Compression molding
  • Sequential filling
  • Film insert molding
  • Tool cooling
  • Multi component molding
  • Gas assisted analyses

Technology developments

  • 3D for quality prediction of optical lenses
  • Detailed Hot runner simulation

Covestro provides material data for rheological simulation.
