DME Company offers Vortex Core Pins and Plugs. The product is a cost-effective, time-saving method of removing trapped gas from a mold cavity during the molding process.

Vortex Core Pins and Plugs are made of Porcerax II, a porous, sintered metal. Because the material is 25 percent air by volume, it vents gas without the need for a separate venting component. As a result, Vortex Plugs and Pins help reduce mold size, cost and complexity.

This method of venting also delivers benefits including:

·         Cycle time reduction

·         Enhanced part appearance

·         Elimination of burning and shrinkage

·         Fewer flow and knit lines

·         Elimination of short shots

Vortex Pins are 3 inches long and available in diameters of 0.25 inch, 0.375 inch and 0.5 inch. Plugs come in 0.25 inch, 0.5 inch and 1 inch lengths, and in diameters of 0.25 inch and 0.375 inch.


The full line is heat treated to 30-40 HRC for a tensile strength of 74,000 pounds per square inch and hardness of HMV 350-400.
