MULTI-TIP HOT RUNNER NOZZLES PERMIT BALANCED FILLING OF PRECISION TUBULAR PARTS WITHOUT CORE BENDING

DN5/3 Series Multi-Tip Nozzles

To Be Introduced to the U.S. Market by ALBA Enterprises at NPE2015, New Thermoplay® Nozzles Have Been Used in Europe to Mold Pen Barrels in Very High Cavitation Tooling

RANCHO CUCAMONGA, CA, U.S.A., December 17, 2014: New multi-tip hot runner nozzles designed for axial injection of small tubular parts provide balanced filling that prevents flow lines and reduces the risk of core pin bending caused by high injection pressures, it was announced today by ALBA Enterprises, LLC. The company will introduce the nozzles to the U.S. market at NPE2015 (Booth W1323).

Designed by the Italian firm Thermoplay S.p.A., for which ALBA is the North American representative, Thermoplay® DN5/3 Series nozzles can be used for direct lengthwise injection on the walls of parts. They have symmetrically arranged tips that can be located at a minumum of 3.2 mm from each other. This makes the nozzles particularly suited for multi-cavity molding of small precisión parts with limited distance between their axes, or for small mold systems with extremely restricted áreas. The nozzles are also suitable for parts requiring a high degree of concentricity.

ALBA recommends the Thermoplay® DN5/3 Series nozzles for use with high-flow polymers such as ABS, polyethylene, polypropylene, and polystyrene.

“Three-gated Thermoplay DN5/3 Series nozzles have been used successfully in Europe for molding precisión writing instruments,” said Antonio De Longhi, ALBA’s chief technology officer. “In one such application, the molder used them in 64-cavity tooling—a total of 192 gates.”

Another multi-tip nozzle series from Thermoplay, the DL-Syringe Series, is designed for edge gating, with similar advantages for small parts or confined mold systems.
