CAVITY AND CORE COMPONENTS Vortex ® Core Pins and Plugs
Vortex ® Vortex Core Pins and Plugs are made from a porous, sintered metal with a porosity of 25% air by volume. With a series of interconnected pores averaging a diameter of 7 (.0003") microns throughout the material. Using Vortex ® in appropriate areas eliminates gas buildup, reduces injection pressure, lowers cycle times, gloss levels and substantially reduces scrap and reject rates . Vortex Pins and Plugs provide a location-specific method of venting gas. Due to its porosity volume, one fourth of the surface
becomes a vent. Vortex Benefits: •
