Husky Injection Molding Systems’ Ultra SideGate hot runner is designed for direct-gating of parts that would otherwise require gating with a cold runner. Well-suited for deep-draw parts such as pipettes and syringe barrels in which minimal gate vestige is required, the hot runner is capable of producing a vestige as small as about 0.05 mm.

The hot runner offers tip-to-tip spacing as small as 55 mm, requiring a small footprint in the mold and allowing for a large number of cavities in the mold base. Nozzle tips are mounted separately from the nozzle housing into one-piece cavity inserts before hot half assembly, eliminating the need for split cavities, reducing mold maintenance and providing direct access to individual tips without the need to disassemble the entire drop. The Ultra SideGate can support one, two or four tips per nozzle.
