Please confirm all dimensions and nozzle/gating suitability with Husky prior to machining. 2006. 08 9 Nozzle Selection GATING METHODS VALVE GATING Valve gating is used when a flush gate mark with minimal vestige height is required on the molded part. [. . . ] Three criteria are used to determine the best gating option. SHOT WEIGHT MATERIAL COMPATABILITY GATE LOCATION VESTIGE The shot weight per nozzle required to fill the molded part will determine the nozzle size. The resin type to be processed determines suitable gating options. Resin properties to be taken into account include: Amorphous / Semi crystalline Abrasive Additives Used Color Change Frequency Gate location and acceptable gate vestige must be considered. GATING OPTION Please confirm all dimensions and nozzle/gating suitability with Husky prior to machining. 18 2006. 08 Nozzle Selection SELECTION GUIDELINES ULTRA 250 Throughput (grams / sec. ) HT-D HT-T HT-DX HT-U HT-TX Low Medium High 10 4 1 10 4 1 6 2 1 10 4 1 10 4 1 *Noted throughputs are approximate guidelines.

The L-dimension is required for both quotations and design specifications. Refer to the Design Information pages within the Nozzle Selection section for standard L-Dimension ranges. For Ultra 250, Ultra 500, Ultra 750 and Ultra 1000 systems, the customer has the option of specifying the BL-Dimension instead of the L-Dimension. [. . . ]
