The MS-VG8 closes each gate mechanically with a valve pin, leaving a clean witness mark instead of a gate vestige — the standard answer where surfaces face the customer or gates sit on visible faces.
Pins are driven pneumatically with individually adjustable timing, which also opens the door to sequential filling: gates open as the flow front passes, moving weld lines away from critical areas on large or complex parts.
The pin guide package is serviceable from the parting line where the mold design allows it, and each system ships with seal and pin spares for the first maintenance interval.
