About V-Glace

[Glass Mold Simulation CAE Software]

V-Glace The “World’s First” CAE software

The “World’s First” CAE software that can simulate the process of glass mold forming by incorporating glass properties, developed in collaboration with RIKEN. 3D simulation of the glass mold forming process using V-Glace enables process optimization and results analysis.

Glass Mold

The software can perform stress analysis, heat transfer analysis, structural relaxation analysis, and viscoelastic analysis of molds and glass during the pressing process at high temperatures.
In particular, it can be used as a guideline for process optimization because it can output virtual temperatures that serve as an indicator of changes in the glass state during the cooling process. As a result, the intuition and experience of skilled workers and the behavior of samples in the mold, which until now have been a black box, can be quantified, contributing to improved quality and productivity through the accumulation of know-how.

Shorten Development Period and Reduce Costs

By performing a simulation before mold design, it is possible to predict correction points such as molds, molding conditions, and preforms. As a result, the number of mold modifications and prototypes can be reduced, contributing to shorter development times and lower costs.

Simulation Samples

We present four sample simulations.It is possible to analyze the heat transfer, shape change, stress time changes, of the glass material in the mold with animation.This allows us to observe  the differences in glass material behavior caused by differences in preform geometry and molding patterns.

Examples of Analysis Undertaken

We undertake simulations based on information provided by the customer, including the shape data of molds and preforms, control information such as load, displacement, and temperature conditions during the molding process, and the name of the glass material used. We construct simulation models and conduct molding simulations. We can provide final shape, residual stress distribution, deformation process during pressing, etc. Additionally, parameter surveys based on specified multiple conditions are also possible.

Molding Consultation

We provide consultation on mold shapes, preform shapes, molding process conditions, and other factors to ensure stable production, proposing optimization of the molding process.

Contract Analysis of Physical Properties

It measures and records the physical property values of samples used in simulations, thereby contributing to more accurate simulations. This includes parameters such as creep, friction coefficient, and structural relaxation, which are essential for the simulations.
