Dynamic mold venting valve SGD
The dynamic SGD mold venting valve is an innovative solution able to help resolve the most common effects of poor cavity venting. SGD 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. SGD 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.
Gas venting ejector pin SGDE
The gas venting ejector pin SGDE incorporates the dynamic venting technology 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. The venting ejector pin can be placed inside the cavity where the filling pattern produces gas traps or at last filling point. 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.
