Friedrichshafen, Germany — Italy-based hot runner manufacturer HRSflow GmbH, a division of mold maker Inglass SpA, is touting the control capabilities of its FlexFlow system for injection molding ...

In high-volume injection molding, hot runner systems are the silent workhorses behind every shot. They govern how melt flows, how cavities fill, how much pressure is needed, and, ultimately, part ...

Filters, shown here in cross section, should be purged of foreign debris if elevated injection pressures appear. Nozzles have been threaded into the manifold in this two-shot system with air-actuated, ...

Cycle time is the primary cost measure of the molding process, and cooling represents about 80% of the molding cycle (see Figure 1). The thicker the part, the longer the cycle time. However, the ...

Running purging compound through hot runner channels can remove residual materials while leaving a minimal amount of residue behind. This ensures continued proper and efficient operation of a molding ...
