To overcome the temperature sensitivities of optical materials like PC, PMMA, and cycloolefin copolymers, a new hot runner system eliminates local overheating of material and long residence times. The ...

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, ...

The company has developed integrated hot-runner technology, combining a unitized design with a simple mold-design modification. Injection molders benefit from the integrated approach in several ways: ...

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 ...

Oerlikon HRSflow has introduced an improvement to its HRScool hydraulic cylinder system for hot-runner injection molding, first introduced in 2019, which uses advanced temperature management ...

Italian hot runner manufacturer HRSflow GmbH, a division of mold maker Inglass SpA, is showing a range of product developments aimed at improving the injection molding process. HRSflow's largest ...
