VISI Flow
Moulding design
All areas of moulded component creation can benefit from the optimisation of mould tool design and
moulding process parameters. Part designers, mould makers and moulders will all benefit from using
Vero’s patented technology for injection simulation to achieve cost-effective and reliable mould
designs and the optimum moulding conditions.
VISI Flow is a unique prediction tool, ideal for pre- and post-production analysis and con-current
engineering of injection moulded plastic components.
Pre-production analysis
* Before designing the tool design do preventive analysis;-
such as welding lines
air traps
best gate location etc
test wall thickness distribution
overall quality of the finished component
maximize the choice of moulding material
design changes can be implemented with minimum impact on tooling corrections
save on expensive moulding trials
Post-production analysis
* Better understand conditions inside the mould cavity during the moulding cycle.
* Help judge the effectiveness of different corrective actions.
* Produce the most effective improvements to the moulding results.
Con-current engineering
* Made possible through an integrated CAD/CAM/CAE analysis.
* Uninterrupted data exchange between the design and analysis environment.
* Identify possible critical situations.
* Set the most effective moulding parameters.
* Optimise the runners and cooling layout.
* Predict problems concerning any part of the plastic component creation process.
VISI Flow is the most cost effective solution, providing a user friendly interface
with short model preparation and calculation times.
Initially introduced to the injection simulation market over 25 years ago, VISI
Flow combines the powerful versatility of VISI Modelling with the undisputed
result accuracy of Finite Element Analysis. VISI Flow provides the complete
solution for part/mould designers and plastic injection moulding technicians:
from filling analysis, to warpage calculations and thermal optimisation
analysis.
Extensive range of CAD interfaces.
* Parasolid, IGES, DXF, DWG, STL and VDA
* STEP, Solid Works and Solid Edge
* CATIA v4 & v5, Pro-E, UG and ACIS
Simple design of runner and cooling systems
* Import or creating one of the most important mould tool features.
* Any feeding and conditioning system.
* No limit to the complexity.
* Easily edited to allow for a comparative analysis to be calculated.
Patented meshing technology
* Hybrid meshing technology.
* Perform 3-dimensional flow simulation.
* Very short calculation times.
* Solid mesh creation is an automated function.
* Short model preparation times.
* Rapid analysis calculations.
* Meshing approach gives consistent results.
* Unaffected by component size, complexity or wall thickness.
Materials database
* Accuracy of result is directly related to the material characterisation.
* Extensive material database.
* Ability to easily add new polymer grades.
* Modify the existing data to match the exact moulding material.
Filling phase
* Control the injection of molten polymer into the mould cavity.
* Moulding parameters are suggested for an accurate moulding.
* Minimum input from the operator.
* Limited experience required to create an analysis.
* The filling simulation provides;-
ability to forecast and visualise component filling
identify potential aesthetic issues
clamp force
pressure
temperature
shear stress
frozen skin
fibre orientation etc.
Shape phase module
* Investigate polymer during the holding and freezing time.
* Identify sinking or voids caused by packing.
* Visualise and measure the final moulded shape.
* Many tools provided for evaluating the result including;-
viewing displacement along an axis
querying point locations to calculate the warpage
linear shrinkage
export warped model geometry for comparison with CAD data
Thermal phase module
* Analyse the effect of the thermal conditioning.
* Use cooling channels of VISI Mould for thermal simulation.
* Run analysis by considering all possible thermal effects including;-
heat exchange among plastic and blocks
hot and cold runners
mould inserts with high conductive materials
* Analyze the cooling system to visualise warpage.
* Define the best cooling layout to achieve the short cycle times.
Complete analysis of the moulding process
* Optional modules for simulation of;-
sequential moulding
gas-assisted
co-injection
overmoulding
crosslinking grades
