This document provides technical information on the Synventive Hot Runner Manifolds, Series VH, used in injection molding applications. It includes product specifications, component descriptions, dimensional data, and manifold types. The guide emphasizes consulting the Synventive Hot Runner Guide for detailed design and application information.

1. Product Description and Components

• Series VH Hot Runner Manifolds: Designed for precise melt flow control in injection molding.
• Main Components: Manifold block with heaters and thermocouples, inlet bushing (heated or unheated), centre support, dowels, and support pads.
• Material Notes: Hardened inserts are recommended but not supplied; dimensions depend on nozzle selection and material.

2. Dimensional Specifications

• Manifolds are available in standard shapes: I, H, X, Y, and customizable shapes.
• Key dimensions include manifold thickness, width, flow bore diameter, inlet bushing diameter, and expansion gaps.
• Typical manifold sizes range with lengths from 50 mm up to 200 mm and flow bore diameters from 5 mm to 25 mm.
• Inlet bushings come in various lengths and can be heated or unheated, with size codes such as BC 025 50.

3. Attached Parts and Accessories

• Centre supports tailored to nozzle sizes.
• Dowels and support pads for assembly and stability.
• Recommendations to use hardened inserts for durability.

4. Manifold Types and Configurations

• Standard Shape Manifolds: Designed for common cavity and runner layouts (I, H, X, Y).
• Customized Shape Manifolds: Tailored to customer specifications using Series VH components.
• Bridge Manifolds: Enable combining multiple manifolds into one feed system, designed per customer requirements.
• Manifold type codes use capital letters indicating shape and runner layout; numbers indicate nozzle count.

5. Design and Application Recommendations

• Consult the Synventive Hot Runner Guide for detailed design parameters and application-specific advice.
• Illustrations are schematic and not to scale; actual dimensions depend on nozzle and material choices.
• Errors and omissions are excepted; for specific applications, direct consultation with Synventive is advised.

Critical Information Summary

• Use hardened inserts for improved wear resistance (not supplied).
• Manifold dimensions and inlet bushing specifications must be selected based on nozzle size and material.
• Multiple manifold shapes and configurations allow flexible integration into injection molding systems.
• Heated inlet bushings are available to maintain melt temperature control.
