Glass Engineer System

GE-System(Glass Engineering System) software helps glass engineers to quickly predict the glass properties and optimize the glass component design.

Glass engineers and researchers can use this software to develop new glass products and improve the old product design.

Why GE-System? – Save Your Time & Money!

Optimization components design reduces the test times for melting, improve the glass product property,and reduce the melting temperature. So you can save money and time.

Glass Engineer System is very stable

GE-SYSTEM version 1.0 was released in 1994 and was the first glass engineer software running on PC. The current version now is 10.0(2010) and very stable.
To use the GE-SYSTEM is very simple and fast.

Over 150 properties include optical,mechanical,electrical,chemical,thermal,laser and high temperature of melting
