Synflow technology by Synventive Molding Solutions retains all of the functionality of previous versions. Synflow helps molders eliminate cosmetic defects on sequentially filled parts that are caused by sudden flow front accelerations and stagnations created when the delayed pins open. 

Synventive plans to release the third generation of Synflow late in 2017. Synventive says it has improved Synflow’s functionality, performance and user experience. With Synflow, it is now possible to stop the pin and hold it at any position mid-stroke, which enables individual flow rate control of each nozzle to balance family molds or to fill complex multi-gated geometries. Synflow can program alternating opening profiles, which offers the ability to pre-fill cold runners or to create differential packing within complex multi-gated parts.

Synventive says that it is easy to upgrade to Synflow after molding parts. The company also says that Synflow Technology installs and starts running in minutes. All Synventive valve gated hot runners can come standard with SVG+, which includes position sensors that enable the simple Synflow upgrade.
