HOT SPRUE BUSHING TIP STYLE

SPRUE GATE TIP

STANDARD / EXTENDED

For use where gate vestige is allowed. Provides low resistance to flow with excellent flow rates.

Extended style provides additional stock for machining profiles or part contours.

RING GATE TIP

STANDARD / EXTENDED

Ideal for low vestige commodity and engineering grade resin applications. The Ring Gate features

a sealed tip for efficient shut-off at the part surface. Available with standard or wear resistant

needles. Extended style provides additional stock for machining profiles or part contours.

POINT GATE TIP

Suitable for high viscosity resins, engineering plastics and applications requiring optimum gate

cosmetics with minimal gate vestige. Available with standard or wear resistant needles.

NOTE:

Temperature and density values shown above are general, and may not apply to your

application. Please refer to proper processing data for the resin grade intended for your specific

application. Failure to use temperature settings appropriate to the specific resin and resin grade

intended for your application may result in poor part quality, or inability to produce acceptable

molded parts.
