Overview

This document provides comprehensive technical specifications, design guidelines, and configuration instructions for the Synventive 04 S01 series hot runner nozzles, focusing on dimensional data, nozzle tip variants, heating zones, and application recommendations for thermoplastic materials.

1. Product Description and Classification

• Series & Type: 04 S01 series, single nozzle, open style with a 4 mm flow bore diameter.
• Nozzle Versions: Basic version succeeding the CA ... E series.
• Nozzle Tip Types: Multiple gating types including open, open with torpedo, and valve gate options.
• Heating Zones: Typically 2 zones numbered from nozzle tip to head, with power ratings up to 410 W per zone.
• Thermocouple: Fe/CuNi type compliant with DIN 437 standard.
• Operating Voltage: 230 V AC externally heated.
• Application: Suitable for all common thermoplastics; maximum shot weight per nozzle is 70 g for open, low viscosity materials.

2. Dimensional Specifications and Tolerances

• Key Dimensions: Nozzle length (L), head height (H), bore diameters (Dt), centring diameters, and radii (R) are precisely defined with tolerances.
• Tolerances: General tolerances follow DIN ISO 2768-mK standard.
• Length Range: Nozzle lengths vary from 36 mm to 126 mm depending on length code and tip shape.
• Cut Out Details: Specific dimensions for mould plate cut outs, nozzle tips, and locking pin groove/bore ensure correct installation and rotation prevention.

3. Nozzle Tip Variants and Gating Types

Several nozzle tip shapes and gating types are described, each optimized for different processing windows and material characteristics:

• Y01T: Open with torpedo, version 01 for medium to wide process windows.
• Y02T: Open with torpedo, version 02 for narrow to medium process windows.
• Y03T: Open with torpedo, version 03 designed for abrasive materials.
• F01T: Open with torpedo, version 01 with a different tip shape (F) for medium to wide process windows.
• Additional Series: F02T, F03T, W01T, W02T, and X01T series with specific tip shapes and cooling requirements; some optimized for abrasive materials.

All variants require cooling around or opposite the nozzle tip and must be positioned so the nozzle tip front contacts the plastic directly.

4. Configuration and Selection Guidelines

• Nozzle Description Completion: Users must specify series, type, length code, and heater zone power based on provided tables and schematic drawings.
• Length Code: Corresponds to specific nozzle lengths or ranges depending on series.
• Heater Zones: Numbered from nozzle tip; power ratings standardized up to 410 W per zone.
• Drawings: Provided illustrations are schematic and not to scale but serve as essential configuration references.

5. Installation and Application Notes

• Locking Pin Groove/Bore: Prevents nozzle rotation; detailed dimensions referenced (page 2 of original document).
• Mould Plate Cut Outs: Must follow specified dimensions for proper nozzle and connection fit.
• Surface and Shape Tolerances: Critical for sealing and mechanical stability.
• Consultation: Recommended for specific applications or deviations from standard configurations.

6. Standards and References

• General tolerances and surface finish requirements comply with DIN ISO 2768-mK.
• Thermocouple specifications follow DIN 437.
• Further design and application details are available in the Synventive Hot Runner Guide.

Critical Parameters and Limitations

• Maximum nozzle length: up to 126 mm depending on tip and length code.
• Maximum nozzle contact radius: 40 mm.
• Maximum length tolerance: ±0.05 mm.
• Maximum heater power per zone: 410 W.
• Maximum shot weight per nozzle: 70 g for open, low viscosity materials.
