[. . . ] Introduction OVERVIEW Welcome to the Husky Hot Runner Design Center. This information is intended to simplify the hot runner selection process. [. . . ] CAD Library Mold designers are provided with all standard gating methods, nozzles and generic hot runner view installations to be merged into their CAD file. Available formats include:. dxf, . igs, and . prt. NOTE: Please refer to www. hotrunners. com for the most current design information. Please confirm all dimensions and nozzle/gating suitability with Husky prior to machining. 2006. 08 1 Introduction COMPLETE HOT RUNNER SYSTEM Ultra 750 HT/VG Shown Electrical Connector Backing Plate Wire Clip Manifold Thermocouple Manifold Air Line Valve Stem UltraSeal Piston Cylinder Backup Pad Manifold Bushing Manifold Plate Locating Ring Center Locating Insulator Sprue Bushing Nozzle Heater Nozzle Housing Tip Retainer Tip Insert Plate Cooling Backup Insulator Pad Manifold Heater Cavity Interface Tap Plate Bolt Guide Pin Plate Alignment Dowel Please confirm all dimensions and nozzle/gating suitability with Husky prior to machining. 2 2006. 08 Introduction MANIFOLD SYSTEM Ultra 750 HT/VG Shown Backup Pad Nozzle Tip Valve Stem Piston Melt Channel Piston Seal Manifold Manifold Bushing Center Insulator Sprue Heater Sprue Bushing UltraSeal Nozzle Heater Backup Insulator Pad Carbide Insert Tip Nozzle Housing Manifold Heater Please confirm all dimensions and nozzle/gating suitability with Husky prior to machining. 2006. 08 3 Introduction SINGLE CAVITY VALVE GATE SYSTEM Ultra 750 SCVG Shown Sprue Body Heater Sprue Body Insert Nozzle Heater Nozzle Tip Valve Stem Locating Ring Air Line Tip Insulator Please confirm all dimensions and nozzle/gating suitability with Husky prior to machining. 4 2006. 08 Introduction HOT SPRUE Ultra 750 HS Shown Insulator Body Nozzle Heater Band Heater Nozzle Tip Retainer Locating Ring Nozzle Tip Please confirm all dimensions and nozzle/gating suitability with Husky prior to machining. 2006. 08 5 Introduction INTRODUCTION HOT RUNNER SYSTEMS The objective of a hot runner system is to distribute the material from the machine nozzle to each gate, while minimizing adverse effects to the material's properties. Husky offers two hot runner system types: · · Complete hot runner system with plates Manifold system Complete Hot Runner System A complete hot runner system is supplied to the customer as a fully assembled unit, ready to be fastened to the cavity plate and installed into the machine press. Manifold System A manifold system includes all components that make up the heated flow path except the hot runner plates. Drawings that outline the necessary plate machining to accommodate the manifold and related components are included with every shipped manifold system. Benefits of Ordering Complete Hot Runner System vs. Manifold System Customer benefits when ordering a complete hot runner system: · · Husky's extensive design experience With a complete system, plate features such as: cooling circuits, air circuits, wire channels, and plate bolts are optimally positioned to maximize performance. 3-Year Leak-Proof Guarantee for UltraSealTM systems. Complete hot runner is ready to be fastened to the cavity plate and begin production. Simplified communication by providing one source responsibility. · · · Please confirm all dimensions and nozzle/gating suitability with Husky prior to machining. 6 2006. 08 Introduction Single Drop Assemblies Single drop assemblies are well-suited for single cavity molds and prototype applications. Two single drop system types are available: · · Single Cavity Valve Gate (SCVG). [. . . ] To simplify the drawing, the standard dimension tolerancing, surface finishes, parallelism, and concentricity requirements are listed below and followed throughout the manual. In situations where special tolerances or finishes are used, these are indicated on the drawing.
