Hot Runner Technology Offers Complete Control of Molding Parameters

Synventive introduces its updated Synflow3 technology. Synflow technologies help molders eliminate cosmetic defects on sequentially-filled parts caused by sudden flow front accelerations and stagnations created when the delayed pins open. According to the company, this next generation of Synflow offers more advanced features that enable molders to quickly and easily define the complete molding parameters for a specific application.

Synventive developed Synflow3 with simplicity of use in mind by increasing functionality to greatly improve performance and user experience. The most significant addition to Synflow’s functionality is the ability to stop the pin and hold it at any position mid-stroke. This enables individual flow rate control of each nozzle to balance family molds or to fill complex multi-gated geometries. Moldmakers can program alternating opening profiles, offering the ability to pre-fill cold runners or create differential packing within complex multi-gated parts.

During mold sampling, Synflow can be installed and running in a matter of minutes if a brief trial indicates that the technology would benefit the process. No connection to the injection molding machine is necessary, and the same controls equipment can be used on multiple systems.

All Synventive valve-gated hot runners can come standard with SVG+, which includes position sensors that enables a simple upgrade. The Synflow technology can be added to any activeGate-enabled system through simple external hookups.
