A new hot-runner nozzle for close cavity spacing or hard-to-reach areas of the mold is available from Hasco America Inc., Arden, N.C. Its Z3210 Compact Shot nozzle permits center distances as small as 14 mm. It comes 63 to 180 mm long. Thermocouple, heater, and nozzle tip can be changed easily, despite the compact design, Hasco says.


The standard nozzle is fixed by a retaining plate in front of the manifold and the cable ducts are machined in the back of the nozzle retaining plate. A special flanged version can be fixed to the front of the nozzle plate with the thermocouple and heater cables at the front, so as to simplify maintenance.
