Product Introduction

The 140GPM glass molding machine from Moore Nanotechnology Systems is specifically designed for the field of precision optical glass. The grinding configuration of 140GPM matched with 450UPL ultra precision single point diamond machine or 350FG ultra precision free-form surface machine can be used for ultra precision grinding of WC and SiC molds. Therefore, 140GPM is an ultra precision glass molding machine tool. The diameter of the 140GPM processing area is 140mm. The machine tool can choose to configure multi-mode cavity molding method and fully automatic feeding or sorting molding method to meet the requirements of large-scale processing.

The advanced 140GPM is equipped with GPMSim, which is unique（SB SE)FEA software package, used for predicting and analyzing the operating status during glass molding process. The unique capabilities of GPMSim software include: easy to operate work interface, easy to create aspheric cavity, and easy to call and specify glass and mold data from the established material database. The software can automatically generate a quadrilateral network distribution map and simulate the five stages of glass molding to calculate the molding results, namely heating, liquefaction, pressurization, and two cooling processes (one is annealing cooling and the other is rapid cooling). Other predictive functions include residual pressure of glass, deformation of glass, and shrinkage of glass materials.

Machine tool characteristics

Independent cabinet style precision glass molding machine with a processing diameter of 140mm

Can use single hole or multi hole molds

• Compatible with fixed and floating mold devices

The computer fully controls the positioning module and integrates the pressure control module with heating and cooling cycles
