Accessibility to Wider Community, Updated User Interface and 64-bit Support Prime Product for Broader Adoption

FRAMINGHAM, MA - April 24, 2008 - Moldflow Corporation (NASDAQ:MFLO), the leading provider of plastics simulation software that empowers more users to optimize more designs across their enterprise, today announced the release of Moldflow Communicator™ 2.0, a free simulation results viewer that allows distributed product teams to visualize, quantify and compare Moldflow analysis results. New features allow the Communicator to be accessed by a wider audience and updates to the user interface and new operating system support should result in increasing its position as the leading plastics simulation results viewer.

One of the key new enhancements to Communicator 2.0 is support of analysis results from Moldflow Plastics Advisers® (MPA®) 8.1. MPA users can use Communicator files to report their simulation results to other members of a design-to-manufacturing team, regardless of whether or not they are Moldflow customers. Support for MPA results has the potential to significantly broaden the Communicator installed base with new users involved in the design of plastic parts or injection molds.

In addition, an updated user interface continues to provide intuitive navigation through Communicator functionality with the most frequently used features available at the click of a button. The interface will be as easy to use for non-Moldflow customers as it is familiar to existing Moldflow customers. New support for the Microsoft Windows Vista® operating system will help speed product adoption and 64-bit architecture support will allow for the efficient handling of large models.

Murali Annareddy, Director of Product Marketing at Moldflow Corporation, states: ''Moldflow Communicator 1.0 and 1.1 have been extremely popular with Moldflow Plastics Insight® users and their extended development teams, with over 7,500 product downloads since its initial release. Now for the first time, our MPA customers can start realizing the same benefits of sharing dynamic analysis insight with clients, suppliers and design team members, all in an effort to make more informed decisions, reduce development times, improve part quality and speed time to market.''

Moldflow Communicator 2.0 is free and available for download now to both Moldflow customers and non-customers. It runs on 32- and 64-bit hardware running Microsoft Windows Vista® and XP®.
