Overview

This document details the technical specifications, design guidelines, and configuration options for the Synventive 04 C03 series manifold hot runner nozzles with face fit. It targets designers and engineers in injection molding requiring precise nozzle selection and configuration.

1. Product Description and Classification

• Series & Type: 04 C03, part of nozzle class 04 C.
• Nozzle Size: Flow bore diameter fixed at 4 mm.
• Nozzle Style: Manifold nozzle, face fit, optimized for high cavity counts.
• Nozzle Tip: Screw-in interchangeable tips allowing various shapes and gating types.
• Gating Types: Open (with or without torpedo) and valve gate options available.

2. Design and Application Information

• Refer to the Synventive Hot Runner Guide for comprehensive design and application details.
• Consult Synventive for specific applications to ensure optimal nozzle selection.
• Locking pin groove/bore secures nozzle against rotation; details provided on page 2.
• Mold plate cut out dimensions and tolerances for nozzle and connections are specified for proper fit.

3. Configuration and Specification Variables

• Length Code: Defines specific nozzle length or length range per series.
• Heater Zones: Numbered from nozzle tip to head; power ratings typically 180–280 W.
• Thermocouple: Fe/CuNi type per DIN 437 standard.
• Tolerances: General dimensional and surface tolerances per DIN ISO 2768-mK.
• Specification Variables: Include series, type, length code, heater power, and drawn offset.

4. Mechanical and Dimensional Data

• Nozzle lengths range from 86 mm to 186 mm depending on tip shape and gating type.
• Key dimensions include nozzle length (L), head height (H), bore diameter (Dt), and mold plate cut outs with tolerances.
• Flow bore diameter consistently 4 mm across the series.
• Cut outs vary by nozzle tip type (open, torpedo, valve gate).

5. Nozzle Tip Variants and Applications

• Open with Torpedo (Type T): Versions 01, 02, 03 tailored for medium to wide, narrow to medium, and abrasive process windows respectively.
• Valve Gate (Type V): Versions designed for narrow to medium process windows.
• Cooling is mandatory around and opposite the nozzle tip for all variants.
• The nozzle tip front must always contact the plastic melt to ensure proper gating.

6. Heating and Electrical Specifications

• Heaters operate at 230 V AC with replaceable elements.
• Power ratings vary by nozzle length and tip type, typically between 180 W and 280 W.

7. Installation and Assembly Notes

• Locking pin groove/bore prevents nozzle rotation during operation.
• Strict adherence to mold plate cut out dimensions and tolerances is required for proper assembly.
• Surface finishes and dimensional tolerances must comply with DIN ISO 2768-mK standards.

8. Summary of Critical Parameters and Best Practices

• Select nozzle length and tip type based on material process window and application needs.
• Ensure effective cooling around nozzle tips to maintain temperature stability.
• Follow specified tolerances for cut outs and assembly to avoid mechanical issues.
• Consult Synventive for application-specific advice and configuration confirmation.

Additional Details on Nozzle Versions

• Multiple nozzle versions (e.g., 04FT, 04WT, 04WV, 04XT, 04XV) correspond to different process windows and gating types (open with torpedo or valve gate) and tip shapes (F, W, X).
• Versions are optimized for material characteristics including abrasion resistance and process window width.

Tolerances and Standards

• General tolerances conform to DIN ISO 2768-mK, covering shape, position, surface finish, and dimensional limits.
• Locking pin groove/bore and mold plate cut out requirements ensure secure and precise nozzle installation.
