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 demand for hot runner systems has increased with the move toward greater efficiencies, higher productivity, and reduced scrap. That’s pretty much the word from the hot runner systems manufacturers ...

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 ...
