Part and mold design optimization

Flow, cool and warp analysis

Good part and mold design is essential to the production of high quality, injection-molded parts. Computer Aided Engineering (CAE) analysis software is an important tool for optimizing part and mold design. As a leading supplier of polycarbonate resins and blends, Covestro can help customers use these tools to produce quality parts.

Covestro works with customers to optimize part and mold design using filling, cooling and warpage CAE analysis tools. 

  • Filling analysis to predict flow-balancing and filling pressure for runner design and part thickness optimization.
  • Cooling analysis to predict temperature distribution and the existence of hot-spots (if any) for cooling design evaluation and cycle time optimization.
  • Warpage analysis to predict warpage behavior due to non-uninform shrinkage, uneven cooling, and material orientation.

While beneficial for all types of molded parts, flow, cool and warp analysis is particularly advantageous for large, thin-walled parts. TV housing parts, for example, require higher injection pressure and at the same time have less stiffness. Consequently, these parts tend to warp, making part/mold design with such CAE tools necessary.
