A new line of nozzles and manifolds created specifically for small parts and with tight pitches is new from Gunther Hot Runner Systems Inc., Buffalo Grove, Ill. Its Mighty Tight line comes in either a valve-gate design that allows for pitch centers as small as 9 mm or a hot-tip design that allows pitch centers as close as 7 mm. The system is designed to handle engineering materials as well as standard resins. A Double Mighty Tight design, in which two nozzles are housed in one main body, offers pitch spacing down to 12 mm on one axis and 9 mm on the other axis. The nozzles have separate heaters and temperature control to ensure exceptional temperature control at the gate.
