NOZZLE SELECTION
To select the correct nozzle for an application, the following information is required.
• Part weight and desired throughput per nozzle.
• Material and additives.
• Acceptable vestige and gate location.
To accommodate a wide range of molded part sizes, Husky offers 4 standard nozzle sizes. Each nozzle offers a variety of
different gating methods.

GATING METHODS
VALVE GATING
Valve gating is used when a flush gate mark with minimal vestige height is required on the molded part. Valve gating
allows for larger gate diameters, minimizing molded-in stress and providing easier part filling. All valve gating options use a
pneumatically operated valve stem to mechanically shut off resin flow at the gate.

HOT TIP GATING
Hot tip gating is used when a small gate mark on the molded part is acceptable. The size of the vestige is affected by
the gate size, gate cooling, material, and processing conditions. Gate solidifica tion is achieved b y the r emoval of he at from
the gate area following the injection cycle.
