A company has designed a material- and timesaving hot runner specifically for injection-molding deep-draw medical device components such as pipettes and syringe barrels. The technology enables parts that would otherwise require gating with a cold runner to be direct-gated and supports molding applications in which component quality and gate vestige are critical considerations. The Ultra SideGate accommodates single-piece mold cavities, which eliminates the surface-quality issues associated with split-cavity designs, and it limits the size of gate vestiges on finished parts to approximately 0.05 mm. Offering tip-to-tip nozzle spacing down to 55 mm and a small nozzle housing area that accepts 1-, 2-, and 4-tip configurations, the system allows molds to have a large number of cavities while maintaining a relatively small footprint. Users can access the individual nozzle tips without removing the mold from the machine.
