Prevent defects

Through the predictive analysis of glass flow in the mold, manufacturers gain valuable insights into potential defects that may occur during the production process. Armed with this knowledge, they can proactively adjust the tooling and optimize production parameters to enhance precision and consistency in design. By utilizing simulation software, manufacturers can significantly reduce the occurrence of defects, ultimately leading to improved product quality.


Lower container weight

By optimizing design and manufacturing parameters, simulation software effectively reduces container weight in glass forming. This leads to a decrease in material usage and costs while ensuring the structural integrity of the final product. As a result, the implementation of simulation software contributes to environmental sustainability by minimizing raw material consumption and reducing energy usage during production.



In the realm of glass forming, simulation software facilitates rapid and efficient prototyping and testing. With its accurate and reliable simulations, manufacturers can quickly assess various glass forming techniques, detect potential challenges, and optimize the manufacturing process with precision and effectiveness.

We meet your challenges

For bottles

Transvalor computing solutions allow the mastering of the quality and final performances of a mold-blown bottle, an accurate prediction of the thickness in the final stage at any point of the glass container, local defects including necking defects, the temperature distribution at any time of the process and the optimal pressure cycle to apply. The software includes a dedicated model for glass (Fulcher) with available data.


Forge svg (1)

FORGE® is a leading solution for the simulation of hot, warm and cold forging processes.

Glass containers are produced based on 2 major processes, blow-blow process and press-blow process. FORGE® addresses these 2 processes.

The software provides an accurate prediction of:
  • The thickness in the final stage at any point of the glass container,
  • Local defects including necking defects,
  • The temperature distribution at any time of the process,
  • The optimal pressure cycle to apply.

For molds

The optimal blank mold’s shape or bottle characteristic (shape, stress, temperature distribution) can be predicted thanks to the optimization module integrated in the software. The cyclic heating metal molds can be predicted thank to the thermal steady state feature integrated in the software.
