Overview

This document provides detailed technical specifications and configuration guidelines for the Series 16 E01 manifold nozzles with screw fit, designed for hot runner systems in injection molding. It covers nozzle dimensions, heating zones, gating types, tolerances, cooling requirements, and selection criteria for various thermoplastic applications.

1. Product Description

• Nozzle Size: 16 mm flow bore diameter.
• Style: Manifold nozzle with screw-in interchangeable tips.
• Gating Types: Open, open with torpedo, valve gate.
• Heating: External heating with 230 V AC, 1 to 3 zones, power up to 1660 W depending on length and type.
• Thermocouple: Fe/CuNi type per DIN 43710.
• Applications: Suitable for common thermoplastics; max shot weight 2500 g (open), 1500 g (valve gate).

2. Dimensions and Tolerances

• Nozzle length (L), cut-out lengths (L1), diameters (D, D1), and heights (H) vary by tip shape and length code.
• General tolerances follow DIN ISO 2768-mK standards.
• Mold plate cut-outs for nozzle and connections are specified, including electrical and thermocouple placements.
• Different cut-outs apply for through bore and blind bore nozzle tips.

3. Nozzle Tip Types and Gating

• Interchangeable screw-in tips with shape codes (Y, U, P, K, L, etc.).
• Gating options: Open (N), Open with torpedo (T), Valve gate (V).
• Version 01 is standard; variations accommodate materials with narrow to wide process windows.

4. Heating Zones and Power Ratings

• Heating zones numbered from nozzle tip to head.
• Power ranges from 400 W to 1660 W depending on length code and nozzle type.
• Cooling required around nozzle tip and opposite side based on gating type.

5. Selection and Configuration

Tables and charts guide selection of nozzle length codes, tip shapes, gating types, and heating power tailored to application needs. Users are advised to consult the Synventive Hot Runner Guide for comprehensive design and application details.

6. Installation and Application Notes

• Nozzle tip front must contact plastic to ensure proper gating and flow.
• Cooling requirements vary by tip and gating type.
• Locking pin groove/bore details are critical for secure installation.
• Illustrations are schematic; verify dimensions from official data sheets.

7. Summary of Critical Parameters

8. Recommendations and Best Practices

• Ensure nozzle tip front is in contact with plastic to avoid defects.
• Apply appropriate cooling around nozzle tip as specified.
• Consult Synventive Hot Runner Guide for detailed design and application guidance.
• Verify all dimensions and tolerances per DIN ISO 2768-mK before installation.
• Select nozzle tip shape and gating type based on material process window and application needs.

9. Nomenclature and Series Revisions

Users should be aware of nomenclature changes between older and newer nozzle series, which may affect length codes and compatibility.

10. Summary of Nozzle Types and Features

11. Critical Considerations

• Nozzle tip front must always contact plastic for proper gating.
• Cooling must be applied both around and opposite the nozzle tip for thermal stability.
• Heater power and nozzle length selection must align with molding process and material characteristics.
• Consult Synventive for application-specific adaptations or clarifications.

12. Nozzle Specification and Configuration Guidance

• Complete nozzle description by selecting series, type, and length code from provided charts.
• Adhere to DIN ISO 2768-mK tolerances for shape, position, and surface finish.
• Configure heater power within specified wattage ranges for optimal thermal control.
• Refer to locking pin groove/bore details (page 2) for secure attachment.
• Ensure correct mold plate cut-out dimensions for nozzle and connections.
• Use regional contact information for technical support and inquiries.

This structured summary consolidates the essential technical data, configuration options, and best practices for Synventive Series 16 E01 manifold nozzles, facilitating accurate specification and effective application in hot runner injection molding systems.
