PRODUCT SERIES
SD Direct Nozzle
Open runner gating for the main series of high-temperature and corrosive grades
SD DIRECT NOZZLE FEATURE
Zero stringing, zero drooling, no gate clogging—maintenance-free during the warranty period.
Technology
Open gate (tip remains open; no valve pin)
Gating
Runner gating (melt enters the cavity via the runner)
Minimum nozzle outer diameter
Ø13 mm
Minimum bore
Ø14 mm (mold mounting bore)
Minimum center distance
15 mm (nozzle-to-nozzle center distance)
Structure and gating
A straight-through channel without a valve pin or spring assembly. Melt flows directly from the runner to the gate, ideal for molds that can be gated directly from the runner.
Vestige and break
A small stub remains at the gate and is removed in a secondary step. Breakage is achieved by controlling the gate temperature to freeze the melt, which reduces stringing and drooling.
Models
Five sizes cover the common range. Verify nozzle length, mounting bore, and wiring against the mold layout.
