Software produces designs from models
MoldDesign software from Bentley Systems Inc. generates mold-base designs directly from three-dimensional models.
MoldDesign is integrated with the Exton, Pa., firm's solid modeler, the MicroStation Modeler.
The software designs mold plates and components. It also details locations of slots and holes. Users pick from a catalog of parts, such as plates, leader pins, bushings and ejectors. The catalogs include parts from a number of companies.
MoldDesign is integrated into Bentley's MechanicalSpace Continuum system.

EDI manifold design debuts in Thailand
Flat-die maker Extrusion Dies Inc. introduced a new manifold design for cast film and coatings at ASEANplas '98 in Bangkok, Thailand, in March.
The Multiflow VI gives processors the advantages of internal deckling in operations that require dies that have manifolds with varying cross sections.
The deckle is a device that changes the width of plastic coming out of a flat die by blocking off part of the melt flow.
EDI of Chippewa Falls, Wis., offers the Multiflow VI design on new single- and multimanifold dies. The system provides deckle widths of eight to 12 inches on a side.
In manifolds with varying cross sections, the cross-sectional depth diminishes from the center of the die to either end, to optimize melt distribution, the company said. But until now, this prevented the use of an internal deckle because a deckle required a constant cross section. One solution is an external deckle, placed in front of the die opening. But EDI said an internal deckle produces better film.
EDI said Multiflow VI combines manifolds of its 4-year-old Multiflow V, which has an elongated-teardrop configuration with a diminishing cross section, and constant cross-section manifolds like Multiflow IV.
A straight ``gull-wing'' section has a constant depth to handle varying deckle positions.

Battenfeld offering film winder system
Battenfeld Gloucester Engineering Co. Inc. is selling a new servo-driven indexing system for stretch film winders.
The unit is designed for a rapid, profiled movement during indexing on both blown and cast film winders, according to the Gloucester, Mass.-based firm.
The system controls turret speed through the indexing cycle, at speeds of one, 11/2, two or eight seconds. A programmable logic controller runs the indexer.

Moldflow Corp. touts Release 9.5 program
Moldflow Corp. said its Release 9.5 of the Dynamic Series of design software simplifies the software's ability to take a solid model and automatically create a midplane mesh for a computer model of an injection molded part.
The Lexington, Mass., company said 9.5 integrates Moldflow's MF/Midplane with MF/View. The integration merges automatic midplane mesh creation with powerful editing functions, the firm said.
