Synventive Molding Solutions Inc. of Peabody, Mass., continues to build on its trademarked Dynamic Feed technology.
The technology includes a hot-runner system and a computer-based data-acquisition and hydraulic control unit.
The firm began developing the product in 1996, started commercial sales in 1999 and in mid-2000 started beta-testing modifications to mold larger parts and use a different hot-runner system and newer user-interface versions.
By midyear, version 3.0 software will incorporate pin positioning and a simplified user interface. Upcoming is a multizone hot runner that European processors have requested.
The closed-loop, flow-control technology can significantly reduce the cost of delivering a product to market, said Paul Jensen, vice president and global Dynamic Feed business manager.
``We are right on the brink of something that is going to change the plastics processing industry,'' he said. Jensen termed current estimates of under-one-year payback on a Dynamic Feed investment as conservative.
The controller obtains input from the molding machine, monitors valve pressures and sends signals to the hydraulic unit. Independent control of each nozzle's valve position results in optimal injection and pack profiles.
Synventive focuses on three applications: high-volume precision molding of tight-tolerance parts in a multicavity mold, precision cavity filling for larger highly functional parts, and use of flexible modular tooling, or family molds, to make different parts with inserts in the same mold.
