New nozzle permits sandwich molding. (Keeping up with Injection Molding).Capability for multi-material sandwich molding has been added to the TM series of toggle To alternate back and forth between two states. toggle - To change a bit from whatever state it is in to the other state; to change from 1 to 0 or from 0 to 1. This comes from "toggle switches", such as standard light switches, though the word "toggle" actually refers to presses from Battenfeld of America, West Warwick West Warwick (wôr`wĭk, –`ĭk), town (1990 pop. 29,268), Kent co., central R.I., on the Pawtuxet River; set off from Warwick and inc. 1913. Textile manufacturing remains a leading industry. West Warwick includes the village of River Point. , R.I. The new TM BM series features a newly designed two-channel nozzle An orifice in an inkjet print head through which ink is sprayed onto the paper. Print heads with six thousand or more nozzles are common in today's printers. Nozzle head with shorter connecting flow channels that provide more accurate injection control. Shorter channels minimize the volume of the melt flowing through the concentric nozzles, increasing speed and accuracy of material changeover (programming) changeover - The time when a new system has been tested successfully and replaces the old system. . The hydraulic control system has been redesigned so that injection of the core material begins while injection of the skin material is in progress. This method is said to yield blemish-free surfaces and uniform distribution of the core material throughout the flow length. It also ensures constant flow-front velocity without peaks or sharp pressure drops, preventing the appearance of witness marks. An additional pump speeds nozzle shut-off.
