VISI mould making


The modular software system for mould design and manufacture

The optimised end-to-end solution for tool and mould making, VISI supports all parts of the mould making process, from model analysis and plastic flow front simulation, to core and cavity separation, electrode production and 3D tool construction. This industry-specific technology makes VISI the only end-to-end CAD/CAM solution unique to the toolmaking and mould making industry.


VISI Modelling


2D and 3D CAD

VISI Modelling provides a robust and powerful solid and surface modelling platform based around the industry standard Parasolid®. Combined with Hexagon’s surface technology, model analysis and 2D design, VISI Modelling offers complete flexibility to construct, edit or repair the most complex 3D data.


Advanced modelling

Advanced modelling is a set of tools that enable the existing model topology to be changed without compromising model integrity or curvature consistency. For example, it can be the easiest way to introduce warpage compensation into the mould tool.

2D construction

• Extensive construction techniques

• All geometries such as points, lines, circles, splines, profiles

• Trimming, moving, scaling, rotating and mirroring of elements

• Form and position tolerances, surface specifications

• Full dimensioning/measuring functions

3D solid modelling

• Dynamic direct modelling

• Simple generation of solids

• Feature manager

• Wall thickness analysis

• Model kinematics

• Exploded view

• Drawing creation

• Bill of materials


VISI Flow


Plastic flow analysis

The Lite version module simulates the filling phase of the injection moulding process. This is where the initial moulding criteria and gating positions are defined in order to achieve a well-balanced filling of the cavities under optimum manufacturing conditions.


VISI Flow Lite

• Optical criteria (e.g. weld lines, air pockets)

• Pressure and temperature distribution during filling

• Clamping forces

• Shear stress

• Cooling time definition and overall quality
