Venting in Action
A dynamic (versus static) mold-venting valve helps resolve the most common effects of poor cavity venting.
A dynamic (versus static) mold-venting valve helps resolve the most common effects of poor cavity venting. Its design is based on a simple mechanical system allowing the gas to escape from a venting hole that automatically closes under the pressure of the plastic flow front. It can be placed inside the cavity where the filling pattern produces gas traps. The venting hole isn't affected by mold deposits, thanks to the high venting capacity counter pressure of the air inside the cavity is dramatically reduced.
Correct alignment lock selection will reduce maintenance costs, molding downtime and increase part quality over the mold’s entire life.
