MOLDFLOW ANNOUNCES UPGRADED FLOW TECHNOLOGY

(Shelton, Connecticut -- January 27, 1993) Moldflow is now delivering a
significant upgrade of its plastics flow analysis technology in the form
of MF/FLOW Release 8.1 which contains several major new capabilities for
users. First of all, CAD interfacing capability within MF/FLOW has been
significantly improved by the addition of an IGES translator. The Moldflow
modeling program MF/VIEW can now import an IGES generated surface file and
export a finite element mesh suitable for Moldflow analysis. MF/VIEW can
also output this mesh in Patran neutral file format turning MF/VIEW into a
powerful CAD to CAE interfacing tool. As a result, a single model can now
be used for CAD and CAE analysis, reducing model time and modeling errors,
while only requiring an understanding of a single modeling system. Several
tools have been provided to check and correct any imperfections in the
translated model.

Furthermore, hard copy support of screen displays is now available within
Moldflow's modeling and results display program MF/VIEW for HPGL/2 and
Postscript format printers. MF/VIEW 3D analysis results display now
includes sink mark prediction. Light source shading provides a realistic
visualization of sink marks while color-scaled displays show predicted
sink mark depth. 3D flow analysis programs now use an improved solver,
giving shorter analysis time and more accurate pressure prediction.
Automatic 3D graphical runner balancing has been improved, with annular,
tapered, circular and rectangular runner cross sections now being
supported. Extra pressure control options have been added to MF/FLOW,
allowing the user to switch over to packing pressure based on
PVT/Compressability data. This simulates the mold shop practice of
stopping the molding machine ram before the cavity is completely filled,
allowing the melt to expand into the remaining area. Clamp tonnage
prediction accuracy will be improved using this method.

Finally, Moldflow's interactive 2D flow analysis has a new graphical user
interface based on the same Motif standards as the full Moldflow 3D flow
analysis product. All commands are selected via a mouse from pull down
menus, commands do not need to be memorized. Only relevant menu options
are active when a task is selected, making the software intuitive to use,
without requiring specialist skills. Simple 3D modeling requires only the
representative flow path to be created, while on-line recommended material
processing conditions guide analysis inputs. Instantaneous graphical
analysis results include graph plots of melt properties such as pressure
and temperature, while automatic re-dimensioning of runner and cavity
sections gives balanced flow pressures.

Moldflow has pioneered computerized analysis of plastic injection molding,
which improves product performance, reduces scrap, shortens design
leadtimes and lowers design and manufacturing costs. Independent market
surveys have determined that Moldflow has a dominant market share.
Products include: MF/FLOW -- which predicts flow patterns and
characteristics within the mold; MF/COOL --- which analyzes the vital role
of heat exchange and temperature control in the mold; and MF/WARP software
which analyzes the net distortion of the actual molded part and helps
determine its mechanical properties.
